+===================
+Devicetree (DT) ABI
+===================
+
+I. Regarding stable bindings/ABI, we quote from the 2013 ARM mini-summit
+ summary document:
+
+ "That still leaves the question of, what does a stable binding look
+ like? Certainly a stable binding means that a newer kernel will not
+ break on an older device tree, but that doesn't mean the binding is
+ frozen for all time. Grant said there are ways to change bindings that
+ don't result in breakage. For instance, if a new property is added,
+ then default to the previous behaviour if it is missing. If a binding
+ truly needs an incompatible change, then change the compatible string
+ at the same time. The driver can bind against both the old and the
+ new. These guidelines aren't new, but they desperately need to be
+ documented."
+
+II. General binding rules
+
+ 1) Maintainers, don't let perfect be the enemy of good. Don't hold up a
+ binding because it isn't perfect.
+
+ 2) Use specific compatible strings so that if we need to add a feature (DMA)
+ in the future, we can create a new compatible string. See I.
+
+ 3) Bindings can be augmented, but the driver shouldn't break when given
+ the old binding. ie. add additional properties, but don't change the
+ meaning of an existing property. For drivers, default to the original
+ behaviour when a newly added property is missing.
+
+ 4) Don't submit bindings for staging or unstable. That will be decided by
+ the devicetree maintainers *after* discussion on the mailinglist.
+
+III. Notes
+
+ 1) This document is intended as a general familiarization with the process as
+ decided at the 2013 Kernel Summit. When in doubt, the current word of the
+ devicetree maintainers overrules this document. In that situation, a patch
+ updating this document would be appreciated.

-Amlogic Meson8 and Meson8b SRAM for smp bringup:
-------------------------------------------------
-
-Amlogic's SMP-capable SoCs use part of the sram for the bringup of the cores.
-Once the core gets powered up it executes the code that is residing at a
-specific location.
-
-Therefore a reserved section sub-node has to be added to the mmio-sram
-declaration.
-
-Required sub-node properties:
-- compatible : depending on the SoC this should be one of:
- "amlogic,meson8-smp-sram"
- "amlogic,meson8b-smp-sram"
-
-The rest of the properties should follow the generic mmio-sram discription
-found in ../../misc/sram.txt
-
-Example:
-
- sram: sram@d9000000 {
- compatible = "mmio-sram";
- reg = <0xd9000000 0x20000>;
- #address-cells = <1>;

+description: |+
+ ARM's Versatile Express platform were built as reference designs for exploring
+ multicore Cortex-A class systems. The Versatile Express family contains both
+ 32 bit (Aarch32) and 64 bit (Aarch64) systems.
+
+ The board consist of a motherboard and one or more daughterboards (tiles). The
+ motherboard provides a set of peripherals. Processor and RAM "live" on the
+ tiles.
+
+ The motherboard and each core tile should be described by a separate Device
+ Tree source file, with the tile's description including the motherboard file
+ using an include directive. As the motherboard can be initialized in one of
+ two different configurations ("memory maps"), care must be taken to include
+ the correct one.
+
+ When a new generation of boards were introduced under the name "Juno", these
+ shared to many common characteristics with the Versatile Express that the
+ "arm,vexpress" compatible was retained in the root node, and these are
+ included in this binding schema as well.
+
+ The root node indicates the CPU SoC on the core tile, and this
+ is a daughterboard to the main motherboard. The name used in the compatible
+ string shall match the name given in the core tile's technical reference
+ manual, followed by "arm,vexpress" as an additional compatible value. If
+ further subvariants are released of the core tile, even more fine-granular
+ compatible strings with up to three compatible strings are used.

-Juno device tree bindings also share the Versatile Express bindings as
-described under the RS1 memory mapping.
-
-Required properties (in root node):
- compatible = "arm,juno"; /* For Juno r0 board */
- compatible = "arm,juno-r1"; /* For Juno r1 board */
- compatible = "arm,juno-r2"; /* For Juno r2 board */
-
-Required nodes:
-The description for the board must include:
- - a "psci" node describing the boot method used for the secondary CPUs.
- A detailed description of the bindings used for "psci" nodes is present
- in the psci.yaml file.
- - a "cpus" node describing the available cores and their associated
- "enable-method"s. For more details see cpus.yaml file.
-
-Example:
-
-/dts-v1/;
-/ {
- model = "ARM Juno development board (r0)";
- compatible = "arm,juno", "arm,vexpress";
- interrupt-parent = <&gic>;
- #address-cells = <2>;
- #size-cells = <2>;
-
- cpus {
- #address-cells = <2>;
- #size-cells = <0>;
-
- A57_0: cpu@0 {
- compatible = "arm,cortex-a57";
- reg = <0x0 0x0>;
- device_type = "cpu";
- enable-method = "psci";
- };
-
- .....

-Broadcom Northstar Plus SoC CPU Enable Method
----------------------------------------------
-This binding defines the enable method used for starting secondary
-CPU in the following Broadcom SoCs:
- BCM58522, BCM58525, BCM58535, BCM58622, BCM58623, BCM58625, BCM88312
-
-The enable method is specified by defining the following required
-properties in the corresponding secondary "cpu" device tree node:
- - enable-method = "brcm,bcm-nsp-smp";
- - secondary-boot-reg = <...>;
-
-The secondary-boot-reg property is a u32 value that specifies the
-physical address of the register which should hold the common
-entry point for a secondary CPU. This entry is cpu node specific
-and should be added per cpu. E.g., in case of NSP (BCM58625) which
-is a dual core CPU SoC, this entry should be added to cpu1 node.
-
-
-Example:
- cpus {
- #address-cells = <1>;
- #size-cells = <0>;
-
- cpu0: cpu@0 {
- device_type = "cpu";
- compatible = "arm,cortex-a9";
- next-level-cache = <&L2>;
- reg = <0>;
- };
-
- cpu1: cpu@1 {

+title: ARM Coresight Cross Trigger Interface (CTI) device.
+
+description: |
+ The CoreSight Embedded Cross Trigger (ECT) consists of CTI devices connected
+ to one or more CoreSight components and/or a CPU, with CTIs interconnected in
+ a star topology via the Cross Trigger Matrix (CTM), which is not programmable.
+ The ECT components are not part of the trace generation data path and are thus
+ not part of the CoreSight graph described in the general CoreSight bindings
+ file coresight.txt.
+
+ The CTI component properties define the connections between the individual
+ CTI and the components it is directly connected to, consisting of input and
+ output hardware trigger signals. CTIs can have a maximum number of input and
+ output hardware trigger signals (8 each for v1 CTI, 32 each for v2 CTI). The
+ number is defined at design time, the maximum of each defined in the DEVID
+ register.
+
+ CTIs are interconnected in a star topology via the CTM, using a number of
+ programmable channels, usually 4, but again implementation defined and
+ described in the DEVID register. The star topology is not required to be
+ described in the bindings as the actual connections are software
+ programmable.
+
+ In general the connections between CTI and components via the trigger signals
+ are implementation defined, except when the CTI is connected to an ARM v8
+ architecture core and optional ETM.
+
+ In this case the ARM v8 architecture defines the required signal connections
+ between CTI and the CPU core and ETM if present. In the case of a v8
+ architecturally connected CTI an additional compatible string is used to
+ indicate this feature (arm,coresight-cti-v8-arch).
+
+ When CTI trigger connection information is unavailable then a minimal driver
+ binding can be declared with no explicit trigger signals. This will result
+ the driver detecting the maximum available triggers and channels from the
+ DEVID register and make them all available for use as a single default
+ connection. Any user / client application will require additional information
+ on the connections between the CTI and other components for correct operation.
+ This information might be found by enabling the Integration Test registers in
+ the driver (set CONFIG_CORESIGHT_CTI_INTEGRATION_TEST in Kernel
+ configuration). These registers may be used to explore the trigger connections
+ between CTI and other CoreSight components.
+
+ Certain triggers between CoreSight devices and the CTI have specific types
+ and usages. These can be defined along with the signal indexes with the
+ constants defined in <dt-bindings/arm/coresight-cti-dt.h>
+
+ For example a CTI connected to a core will usually have a DBGREQ signal. This
+ is defined in the binding as type PE_EDBGREQ. These types will appear in an
+ optional array alongside the signal indexes. Omitting types will default all
+ signals to GEN_IO.
+
+ Note that some hardware trigger signals can be connected to non-CoreSight
+ components (e.g. UART etc) depending on hardware implementation.

+ The Multi-System Mode Controller (MSMC) is responsible for sequencing
+ the MCU into and out of all stop and run power modes. Specifically, it
+ monitors events to trigger transitions between power modes while
+ controlling the power, clocks, and memories of the MCU to achieve the
+ power consumption and functionality of that mode.
+
+ The WFI or WFE instruction is used to invoke a Sleep, Deep Sleep or
+ Standby modes for either Cortex family. Run, Wait, and Stop are the
+ common terms used for the primary operating modes of Kinetis
+ microcontrollers.

-Hisilicon Hip06 Low Pin Count device
- Hisilicon Hip06 SoCs implement a Low Pin Count (LPC) controller, which
- provides I/O access to some legacy ISA devices.
- Hip06 is based on arm64 architecture where there is no I/O space. So, the
- I/O ports here are not CPU addresses, and there is no 'ranges' property in
- LPC device node.
-
-Required properties:
-- compatible: value should be as follows:
- (a) "hisilicon,hip06-lpc"
- (b) "hisilicon,hip07-lpc"
-- #address-cells: must be 2 which stick to the ISA/EISA binding doc.
-- #size-cells: must be 1 which stick to the ISA/EISA binding doc.
-- reg: base memory range where the LPC register set is mapped.
-
-Note:
- The node name before '@' must be "isa" to represent the binding stick to the
- ISA/EISA binding specification.
-
-Example:
-
-isa@a01b0000 {
- compatible = "hisilicon,hip06-lpc";
- #address-cells = <2>;
- #size-cells = <1>;
- reg = <0x0 0xa01b0000 0x0 0x1000>;

- device_type = "ipmi";

-ARM idle states binding description
-==========================================
-
-==========================================
-1 - Introduction
-==========================================
-
-ARM systems contain HW capable of managing power consumption dynamically,
-where cores can be put in different low-power states (ranging from simple
-wfi to power gating) according to OS PM policies. The CPU states representing
-the range of dynamic idle states that a processor can enter at run-time, can be
-specified through device tree bindings representing the parameters required
-to enter/exit specific idle states on a given processor.
-
-According to the Server Base System Architecture document (SBSA, [3]), the
-power states an ARM CPU can be put into are identified by the following list:
-
-- Running
-- Idle_standby
-- Idle_retention
-- Sleep
-- Off
-
-The power states described in the SBSA document define the basic CPU states on
-top of which ARM platforms implement power management schemes that allow an OS
-PM implementation to put the processor in different idle states (which include
-states listed above; "off" state is not an idle state since it does not have
-wake-up capabilities, hence it is not considered in this document).
-
-Idle state parameters (e.g. entry latency) are platform specific and need to be
-characterized with bindings that provide the required information to OS PM
-code so that it can build the required tables and use them at runtime.
-
-The device tree binding definition for ARM idle states is the subject of this
-document.
-
-===========================================
-2 - idle-states definitions
-===========================================
-
-Idle states are characterized for a specific system through a set of
-timing and energy related properties, that underline the HW behaviour
-triggered upon idle states entry and exit.
-
-The following diagram depicts the CPU execution phases and related timing
-properties required to enter and exit an idle state:
-
-..__[EXEC]__|__[PREP]__|__[ENTRY]__|__[IDLE]__|__[EXIT]__|__[EXEC]__..
- | | | | |
-
- |<------ entry ------->|
- | latency |
- |<- exit ->|
- | latency |
- |<-------- min-residency -------->|
- |<------- wakeup-latency ------->|
-
- Diagram 1: CPU idle state execution phases
-
-EXEC: Normal CPU execution.
-
-PREP: Preparation phase before committing the hardware to idle mode
- like cache flushing. This is abortable on pending wake-up
- event conditions. The abort latency is assumed to be negligible
- (i.e. less than the ENTRY + EXIT duration). If aborted, CPU
- goes back to EXEC. This phase is optional. If not abortable,
- this should be included in the ENTRY phase instead.
-
-ENTRY: The hardware is committed to idle mode. This period must run
- to completion up to IDLE before anything else can happen.
-
-IDLE: This is the actual energy-saving idle period. This may last
- between 0 and infinite time, until a wake-up event occurs.
-
-EXIT: Period during which the CPU is brought back to operational
- mode (EXEC).
-
-entry-latency: Worst case latency required to enter the idle state. The
-exit-latency may be guaranteed only after entry-latency has passed.
-
-min-residency: Minimum period, including preparation and entry, for a given
-idle state to be worthwhile energywise.
-
-wakeup-latency: Maximum delay between the signaling of a wake-up event and the
-CPU being able to execute normal code again. If not specified, this is assumed
-to be entry-latency + exit-latency.
-
-These timing parameters can be used by an OS in different circumstances.
-
-An idle CPU requires the expected min-residency time to select the most
-appropriate idle state based on the expected expiry time of the next IRQ
-(i.e. wake-up) that causes the CPU to return to the EXEC phase.
-
-An operating system scheduler may need to compute the shortest wake-up delay
-for CPUs in the system by detecting how long will it take to get a CPU out
-of an idle state, e.g.:
-
-wakeup-delay = exit-latency + max(entry-latency - (now - entry-timestamp), 0)
-
-In other words, the scheduler can make its scheduling decision by selecting
-(e.g. waking-up) the CPU with the shortest wake-up delay.
-The wake-up delay must take into account the entry latency if that period
-has not expired. The abortable nature of the PREP period can be ignored
-if it cannot be relied upon (e.g. the PREP deadline may occur much sooner than
-the worst case since it depends on the CPU operating conditions, i.e. caches
-state).
-
-An OS has to reliably probe the wakeup-latency since some devices can enforce
-latency constraint guarantees to work properly, so the OS has to detect the
-worst case wake-up latency it can incur if a CPU is allowed to enter an
-idle state, and possibly to prevent that to guarantee reliable device
-functioning.
-
-The min-residency time parameter deserves further explanation since it is
-expressed in time units but must factor in energy consumption coefficients.
-
-The energy consumption of a cpu when it enters a power state can be roughly
-characterised by the following graph:
-
- |
- |
- |
- e |
- n | /---
- e | /------
- r | /------
- g | /-----
- y | /------
- | ----
- | /|
- | / |
- | / |
- | / |
- | / |
- | / |
- |/ |
- -----|-------+----------------------------------
- 0| 1 time(ms)
-
- Graph 1: Energy vs time example
-
-The graph is split in two parts delimited by time 1ms on the X-axis.
-The graph curve with X-axis values = { x | 0 < x < 1ms } has a steep slope
-and denotes the energy costs incurred while entering and leaving the idle
-state.
-The graph curve in the area delimited by X-axis values = {x | x > 1ms } has
-shallower slope and essentially represents the energy consumption of the idle
-state.
-
-min-residency is defined for a given idle state as the minimum expected
-residency time for a state (inclusive of preparation and entry) after
-which choosing that state become the most energy efficient option. A good
-way to visualise this, is by taking the same graph above and comparing some
-states energy consumptions plots.
-
-For sake of simplicity, let's consider a system with two idle states IDLE1,
-and IDLE2:
-
- |
- |
- |
- | /-- IDLE1
- e | /---
- n | /----
- e | /---
- r | /-----/--------- IDLE2
- g | /-------/---------
- y | ------------ /---|
- | / /---- |
- | / /--- |
- | / /---- |
- | / /--- |
- | --- |
- | / |
- | / |
- |/ | time
- ---/----------------------------+------------------------
- |IDLE1-energy < IDLE2-energy | IDLE2-energy < IDLE1-energy
- |
- IDLE2-min-residency
-
- Graph 2: idle states min-residency example
-
-In graph 2 above, that takes into account idle states entry/exit energy
-costs, it is clear that if the idle state residency time (i.e. time till next
-wake-up IRQ) is less than IDLE2-min-residency, IDLE1 is the better idle state
-choice energywise.
-
-This is mainly down to the fact that IDLE1 entry/exit energy costs are lower
-than IDLE2.
-
-However, the lower power consumption (i.e. shallower energy curve slope) of
-idle state IDLE2 implies that after a suitable time, IDLE2 becomes more energy
-efficient.
-
-The time at which IDLE2 becomes more energy efficient than IDLE1 (and other
-shallower states in a system with multiple idle states) is defined
-IDLE2-min-residency and corresponds to the time when energy consumption of
-IDLE1 and IDLE2 states breaks even.
-
-The definitions provided in this section underpin the idle states
-properties specification that is the subject of the following sections.
-
-===========================================
-3 - idle-states node
-===========================================
-
-ARM processor idle states are defined within the idle-states node, which is
-a direct child of the cpus node [1] and provides a container where the
-processor idle states, defined as device tree nodes, are listed.
-
-- idle-states node
-
- Usage: Optional - On ARM systems, it is a container of processor idle
- states nodes. If the system does not provide CPU
- power management capabilities, or the processor just
- supports idle_standby, an idle-states node is not
- required.
-
- Description: idle-states node is a container node, where its
- subnodes describe the CPU idle states.
-
- Node name must be "idle-states".
-
- The idle-states node's parent node must be the cpus node.
-
- The idle-states node's child nodes can be:
-
- - one or more state nodes
-
- Any other configuration is considered invalid.
-
- An idle-states node defines the following properties:
-
- - entry-method
- Value type: <stringlist>
- Usage and definition depend on ARM architecture version.
- # On ARM v8 64-bit this property is required and must
- be:
- - "psci"
- # On ARM 32-bit systems this property is optional
-
-This assumes that the "enable-method" property is set to "psci" in the cpu
-node[6] that is responsible for setting up CPU idle management in the OS
-implementation.
-
-The nodes describing the idle states (state) can only be defined
-within the idle-states node, any other configuration is considered invalid
-and therefore must be ignored.
-
-===========================================
-4 - state node
-===========================================
-
-A state node represents an idle state description and must be defined as
-follows:
-
-- state node
-
- Description: must be child of the idle-states node
-
- The state node name shall follow standard device tree naming
- rules ([5], 2.2.1 "Node names"), in particular state nodes which
- are siblings within a single common parent must be given a unique name.
-
- The idle state entered by executing the wfi instruction (idle_standby
- SBSA,[3][4]) is considered standard on all ARM platforms and therefore
- must not be listed.
-
- With the definitions provided above, the following list represents
- the valid properties for a state node:
-
- - compatible
- Usage: Required
- Value type: <stringlist>
- Definition: Must be "arm,idle-state".
-
- - local-timer-stop
- Usage: See definition
- Value type: <none>
- Definition: if present the CPU local timer control logic is
- lost on state entry, otherwise it is retained.
-
- - entry-latency-us
- Usage: Required
- Value type: <prop-encoded-array>
- Definition: u32 value representing worst case latency in
- microseconds required to enter the idle state.
-
- - exit-latency-us
- Usage: Required
- Value type: <prop-encoded-array>
- Definition: u32 value representing worst case latency
- in microseconds required to exit the idle state.
- The exit-latency-us duration may be guaranteed
- only after entry-latency-us has passed.
-
- - min-residency-us
- Usage: Required
- Value type: <prop-encoded-array>
- Definition: u32 value representing minimum residency duration
- in microseconds, inclusive of preparation and
- entry, for this idle state to be considered
- worthwhile energy wise (refer to section 2 of
- this document for a complete description).
-
- - wakeup-latency-us:
- Usage: Optional
- Value type: <prop-encoded-array>
- Definition: u32 value representing maximum delay between the
- signaling of a wake-up event and the CPU being
- able to execute normal code again. If omitted,
- this is assumed to be equal to:
-
- entry-latency-us + exit-latency-us
-
- It is important to supply this value on systems
- where the duration of PREP phase (see diagram 1,
- section 2) is non-neglibigle.
- In such systems entry-latency-us + exit-latency-us
- will exceed wakeup-latency-us by this duration.
-
- - status:
- Usage: Optional
- Value type: <string>
- Definition: A standard device tree property [5] that indicates
- the operational status of an idle-state.
- If present, it shall be:
- "okay": to indicate that the idle state is
- operational.
- "disabled": to indicate that the idle state has
- been disabled in firmware so it is not
- operational.
- If the property is not present the idle-state must
- be considered operational.
-
- - idle-state-name:
- Usage: Optional
- Value type: <string>
- Definition: A string used as a descriptive name for the idle
- state.
-
- In addition to the properties listed above, a state node may require
- additional properties specific to the entry-method defined in the
- idle-states node. Please refer to the entry-method bindings
- documentation for properties definitions.

+ ==========================================
+ 1 - Introduction
+ ==========================================
+
+ ARM systems contain HW capable of managing power consumption dynamically,
+ where cores can be put in different low-power states (ranging from simple wfi
+ to power gating) according to OS PM policies. The CPU states representing the
+ range of dynamic idle states that a processor can enter at run-time, can be
+ specified through device tree bindings representing the parameters required to
+ enter/exit specific idle states on a given processor.
+
+ According to the Server Base System Architecture document (SBSA, [3]), the
+ power states an ARM CPU can be put into are identified by the following list:
+
+ - Running
+ - Idle_standby
+ - Idle_retention
+ - Sleep
+ - Off
+
+ The power states described in the SBSA document define the basic CPU states on
+ top of which ARM platforms implement power management schemes that allow an OS
+ PM implementation to put the processor in different idle states (which include
+ states listed above; "off" state is not an idle state since it does not have
+ wake-up capabilities, hence it is not considered in this document).
+
+ Idle state parameters (e.g. entry latency) are platform specific and need to
+ be characterized with bindings that provide the required information to OS PM
+ code so that it can build the required tables and use them at runtime.
+
+ The device tree binding definition for ARM idle states is the subject of this
+ document.
+
+ ===========================================
+ 2 - idle-states definitions
+ ===========================================
+
+ Idle states are characterized for a specific system through a set of
+ timing and energy related properties, that underline the HW behaviour
+ triggered upon idle states entry and exit.
+
+ The following diagram depicts the CPU execution phases and related timing
+ properties required to enter and exit an idle state:
+
+ ..__[EXEC]__|__[PREP]__|__[ENTRY]__|__[IDLE]__|__[EXIT]__|__[EXEC]__..
+ | | | | |
+
+ |<------ entry ------->|
+ | latency |
+ |<- exit ->|
+ | latency |
+ |<-------- min-residency -------->|
+ |<------- wakeup-latency ------->|
+
+ Diagram 1: CPU idle state execution phases
+
+ EXEC: Normal CPU execution.
+
+ PREP: Preparation phase before committing the hardware to idle mode
+ like cache flushing. This is abortable on pending wake-up
+ event conditions. The abort latency is assumed to be negligible
+ (i.e. less than the ENTRY + EXIT duration). If aborted, CPU
+ goes back to EXEC. This phase is optional. If not abortable,
+ this should be included in the ENTRY phase instead.
+
+ ENTRY: The hardware is committed to idle mode. This period must run
+ to completion up to IDLE before anything else can happen.
+
+ IDLE: This is the actual energy-saving idle period. This may last
+ between 0 and infinite time, until a wake-up event occurs.
+
+ EXIT: Period during which the CPU is brought back to operational
+ mode (EXEC).
+
+ entry-latency: Worst case latency required to enter the idle state. The
+ exit-latency may be guaranteed only after entry-latency has passed.
+
+ min-residency: Minimum period, including preparation and entry, for a given
+ idle state to be worthwhile energywise.
+
+ wakeup-latency: Maximum delay between the signaling of a wake-up event and the
+ CPU being able to execute normal code again. If not specified, this is assumed
+ to be entry-latency + exit-latency.
+
+ These timing parameters can be used by an OS in different circumstances.
+
+ An idle CPU requires the expected min-residency time to select the most
+ appropriate idle state based on the expected expiry time of the next IRQ
+ (i.e. wake-up) that causes the CPU to return to the EXEC phase.
+
+ An operating system scheduler may need to compute the shortest wake-up delay
+ for CPUs in the system by detecting how long will it take to get a CPU out
+ of an idle state, e.g.:
+
+ wakeup-delay = exit-latency + max(entry-latency - (now - entry-timestamp), 0)
+
+ In other words, the scheduler can make its scheduling decision by selecting
+ (e.g. waking-up) the CPU with the shortest wake-up delay.
+ The wake-up delay must take into account the entry latency if that period
+ has not expired. The abortable nature of the PREP period can be ignored
+ if it cannot be relied upon (e.g. the PREP deadline may occur much sooner than
+ the worst case since it depends on the CPU operating conditions, i.e. caches
+ state).
+
+ An OS has to reliably probe the wakeup-latency since some devices can enforce
+ latency constraint guarantees to work properly, so the OS has to detect the
+ worst case wake-up latency it can incur if a CPU is allowed to enter an
+ idle state, and possibly to prevent that to guarantee reliable device
+ functioning.
+
+ The min-residency time parameter deserves further explanation since it is
+ expressed in time units but must factor in energy consumption coefficients.
+
+ The energy consumption of a cpu when it enters a power state can be roughly
+ characterised by the following graph:
+
+ |
+ |
+ |
+ e |
+ n | /---
+ e | /------
+ r | /------
+ g | /-----
+ y | /------
+ | ----
+ | /|
+ | / |
+ | / |
+ | / |
+ | / |
+ | / |
+ |/ |
+ -----|-------+----------------------------------
+ 0| 1 time(ms)
+
+ Graph 1: Energy vs time example
+
+ The graph is split in two parts delimited by time 1ms on the X-axis.
+ The graph curve with X-axis values = { x | 0 < x < 1ms } has a steep slope
+ and denotes the energy costs incurred while entering and leaving the idle
+ state.
+ The graph curve in the area delimited by X-axis values = {x | x > 1ms } has
+ shallower slope and essentially represents the energy consumption of the idle
+ state.
+
+ min-residency is defined for a given idle state as the minimum expected
+ residency time for a state (inclusive of preparation and entry) after
+ which choosing that state become the most energy efficient option. A good
+ way to visualise this, is by taking the same graph above and comparing some
+ states energy consumptions plots.
+
+ For sake of simplicity, let's consider a system with two idle states IDLE1,
+ and IDLE2:
+
+ |
+ |
+ |
+ | /-- IDLE1
+ e | /---
+ n | /----
+ e | /---
+ r | /-----/--------- IDLE2
+ g | /-------/---------
+ y | ------------ /---|
+ | / /---- |
+ | / /--- |
+ | / /---- |
+ | / /--- |
+ | --- |
+ | / |
+ | / |
+ |/ | time
+ ---/----------------------------+------------------------
+ |IDLE1-energy < IDLE2-energy | IDLE2-energy < IDLE1-energy
+ |
+ IDLE2-min-residency
+
+ Graph 2: idle states min-residency example
+
+ In graph 2 above, that takes into account idle states entry/exit energy
+ costs, it is clear that if the idle state residency time (i.e. time till next
+ wake-up IRQ) is less than IDLE2-min-residency, IDLE1 is the better idle state
+ choice energywise.
+
+ This is mainly down to the fact that IDLE1 entry/exit energy costs are lower
+ than IDLE2.
+
+ However, the lower power consumption (i.e. shallower energy curve slope) of
+ idle state IDLE2 implies that after a suitable time, IDLE2 becomes more energy
+ efficient.
+
+ The time at which IDLE2 becomes more energy efficient than IDLE1 (and other
+ shallower states in a system with multiple idle states) is defined
+ IDLE2-min-residency and corresponds to the time when energy consumption of
+ IDLE1 and IDLE2 states breaks even.
+
+ The definitions provided in this section underpin the idle states
+ properties specification that is the subject of the following sections.
+
+ ===========================================
+ 3 - idle-states node
+ ===========================================
+
+ ARM processor idle states are defined within the idle-states node, which is
+ a direct child of the cpus node [1] and provides a container where the
+ processor idle states, defined as device tree nodes, are listed.
+
+ On ARM systems, it is a container of processor idle states nodes. If the
+ system does not provide CPU power management capabilities, or the processor
+ just supports idle_standby, an idle-states node is not required.

+ The TI K3 family of SoCs usually have a central System Controller Processor
+ that is responsible for managing various SoC-level resources like clocks,

+ through the TI-SCI protocol.
+
+ Each specific device management node like a clock controller node, a reset
+ controller node or an interrupt-controller node should define a common set
+ of properties that enables them to implement the corresponding functionality
+ over the TI-SCI protocol. The following are some of the common properties
+ needed by such individual nodes. The required properties for each device

-======================================
-
-The AP806 is one of the two core HW blocks of the Marvell Armada 7K/8K
-SoCs. It contains system controllers, which provide several registers
-giving access to numerous features: clocks, pin-muxing and many other
-SoC configuration items. This DT binding allows to describe these
-system controllers.
-
-For the top level node:
- - compatible: must be: "syscon", "simple-mfd";
- - reg: register area of the AP806 system controller

--------
-
-
-The Device Tree node representing the AP806/AP807 system controller
-provides a number of clocks:
-
- - 0: reference clock of CPU cluster 0
- - 1: reference clock of CPU cluster 1
- - 2: fixed PLL at 1200 Mhz
- - 3: MSS clock, derived from the fixed PLL
-
-Required properties:
-
- - compatible: must be one of:

+Marvell Armada AP80x System Controller
+======================================
+
+The AP806/AP807 is one of the two core HW blocks of the Marvell Armada
+7K/8K/931x SoCs. It contains system controllers, which provide several
+registers giving access to numerous features: clocks, pin-muxing and
+many other SoC configuration items. This DT binding allows to describe
+these system controllers.
+
+For the top level node:
+ - compatible: must be: "syscon", "simple-mfd";
+ - reg: register area of the AP80x system controller
+
+SYSTEM CONTROLLER 0
+===================
+
+Clocks:
+-------
+
+
+The Device Tree node representing the AP806/AP807 system controller
+provides a number of clocks:
+
+ - 0: reference clock of CPU cluster 0
+ - 1: reference clock of CPU cluster 1
+ - 2: fixed PLL at 1200 Mhz
+ - 3: MSS clock, derived from the fixed PLL
+
+Required properties:
+
+ - compatible: must be one of:
+ * "marvell,ap806-clock"
+ * "marvell,ap807-clock"
+ - #clock-cells: must be set to 1

-LLCC (Last Level Cache Controller) provides last level of cache memory in SOC,
-that can be shared by multiple clients. Clients here are different cores in the
-SOC, the idea is to minimize the local caches at the clients and migrate to
-common pool of memory. Cache memory is divided into partitions called slices
-which are assigned to clients. Clients can query the slice details, activate
-and deactivate them.
-
-Properties:
-- compatible:
- Usage: required
- Value type: <string>
- Definition: must be "qcom,sdm845-llcc"
-
-- reg:
- Usage: required
- Value Type: <prop-encoded-array>
- Definition: The first element specifies the llcc base start address and
- the size of the register region. The second element specifies
- the llcc broadcast base address and size of the register region.
-
-- reg-names:
- Usage: required
- Value Type: <stringlist>
- Definition: Register region names. Must be "llcc_base", "llcc_broadcast_base".
-
-- interrupts:
- Usage: required
- Definition: The interrupt is associated with the llcc edac device.
- It's used for llcc cache single and double bit error detection
- and reporting.
-
-Example:
-
- cache-controller@1100000 {
- compatible = "qcom,sdm845-llcc";
- reg = <0x1100000 0x200000>, <0x1300000 0x50000> ;

+hierarchy.
+
+Required properties:
+- compatible: Must contain one of the following:

+- reg: Contains PRM instance register address range
+ (base address and length)
+
+Optional properties:
+- #power-domain-cells: Should be 0 if the instance is a power domain provider.
+- #reset-cells: Should be 1 if the PRM instance in question supports resets.
+
+Example:
+
+prm_dsp2: prm@1b00 {

-SAMSUNG Exynos SoC series PMU Registers
-
-Properties:
- - compatible : should contain two values. First value must be one from following list:
- - "samsung,exynos3250-pmu" - for Exynos3250 SoC,
- - "samsung,exynos4210-pmu" - for Exynos4210 SoC,
- - "samsung,exynos4412-pmu" - for Exynos4412 SoC,
- - "samsung,exynos5250-pmu" - for Exynos5250 SoC,
- - "samsung,exynos5260-pmu" - for Exynos5260 SoC.
- - "samsung,exynos5410-pmu" - for Exynos5410 SoC,
- - "samsung,exynos5420-pmu" - for Exynos5420 SoC.
- - "samsung,exynos5433-pmu" - for Exynos5433 SoC.
- - "samsung,exynos7-pmu" - for Exynos7 SoC.
- second value must be always "syscon".
-
- - reg : offset and length of the register set.
-
- - #clock-cells : must be <1>, since PMU requires once cell as clock specifier.
- The single specifier cell is used as index to list of clocks
- provided by PMU, which is currently:
- 0 : SoC clock output (CLKOUT pin)
-
- - clock-names : list of clock names for particular CLKOUT mux inputs in
- following format:
- "clkoutN", where N is a decimal number corresponding to
- CLKOUT mux control bits value for given input, e.g.
- "clkout0", "clkout7", "clkout15".
-
- - clocks : list of phandles and specifiers to all input clocks listed in
- clock-names property.
-
-Optional properties:
-
-Some PMUs are capable of behaving as an interrupt controller (mostly
-to wake up a suspended PMU). In which case, they can have the
-following properties:
-
-- interrupt-controller: indicate that said PMU is an interrupt controller
-
-- #interrupt-cells: must be identical to the that of the parent interrupt
- controller.
-
-
-Optional nodes:
-
-- nodes defining the restart and poweroff syscon children
-
-
-Example :
-pmu_system_controller: system-controller@10040000 {
- compatible = "samsung,exynos5250-pmu", "syscon";
- reg = <0x10040000 0x5000>;
- interrupt-controller;
- #interrupt-cells = <3>;
- interrupt-parent = <&gic>;
- #clock-cells = <1>;
- clock-names = "clkout0", "clkout1", "clkout2", "clkout3",
- "clkout4", "clkout8", "clkout9";
- clocks = <&clock CLK_OUT_DMC>, <&clock CLK_OUT_TOP>,
- <&clock CLK_OUT_LEFTBUS>, <&clock CLK_OUT_RIGHTBUS>,
- <&clock CLK_OUT_CPU>, <&clock CLK_XXTI>,
- <&clock CLK_XUSBXTI>;
-};
-
-Example of clock consumer :
-
-usb3503: usb3503@8 {
- /* ... */
- clock-names = "refclk";
- clocks = <&pmu_system_controller 0>;
- /* ... */
-};

-UniPhier outer cache controller
-
-UniPhier SoCs are integrated with a full-custom outer cache controller system.
-All of them have a level 2 cache controller, and some have a level 3 cache
-controller as well.
-
-Required properties:
-- compatible: should be "socionext,uniphier-system-cache"
-- reg: offsets and lengths of the register sets for the device. It should
- contain 3 regions: control register, revision register, operation register,
- in this order.
-- cache-unified: specifies the cache is a unified cache.
-- cache-size: specifies the size in bytes of the cache
-- cache-sets: specifies the number of associativity sets of the cache
-- cache-line-size: specifies the line size in bytes
-- cache-level: specifies the level in the cache hierarchy. The value should
- be 2 for L2 cache, 3 for L3 cache, etc.
-
-Optional properties:
-- next-level-cache: phandle to the next level cache if present. The next level
- cache should be also compatible with "socionext,uniphier-system-cache".
-
-The L2 cache must exist to use the L3 cache; the cache hierarchy must be
-indicated correctly with "next-level-cache" properties.
-
-Example 1 (system with L2):
- l2: l2-cache@500c0000 {
- compatible = "socionext,uniphier-system-cache";
- reg = <0x500c0000 0x2000>, <0x503c0100 0x4>,

- cache-unified;
- cache-size = <0x80000>;
- cache-sets = <256>;
- cache-line-size = <128>;
- cache-level = <2>;
- };
-
-Example 2 (system with L2 and L3):

- compatible = "socionext,uniphier-system-cache";
- reg = <0x500c0000 0x2000>, <0x503c0100 0x8>,

-ML-AHB interconnect bindings
-
-These bindings describe the STM32 SoCs ML-AHB interconnect bus which connects
-a Cortex-M subsystem with dedicated memories.
-The MCU SRAM and RETRAM memory parts can be accessed through different addresses
-(see "RAM aliases" in [1]) using different buses (see [2]) : balancing the
-Cortex-M firmware accesses among those ports allows to tune the system
-performance.
-
-[1]: https://www.st.com/resource/en/reference_manual/dm00327659.pdf
-[2]: https://wiki.st.com/stm32mpu/wiki/STM32MP15_RAM_mapping
-
-Required properties:
-- compatible: should be "simple-bus"
-- dma-ranges: describes memory addresses translation between the local CPU and
- the remote Cortex-M processor. Each memory region, is declared with
- 3 parameters:
- - param 1: device base address (Cortex-M processor address)
- - param 2: physical base address (local CPU address)
- - param 3: size of the memory region.
-
-The Cortex-M remote processor accessed via the mlahb interconnect is described
-by a child node.
-
-Example:
-mlahb {
- compatible = "simple-bus";
- #address-cells = <1>;

+ These bindings describe the STM32 SoCs ML-AHB interconnect bus which connects
+ a Cortex-M subsystem with dedicated memories. The MCU SRAM and RETRAM memory
+ parts can be accessed through different addresses (see "RAM aliases" in [1])
+ using different buses (see [2]): balancing the Cortex-M firmware accesses
+ among those ports allows to tune the system performance.

-Allwinner SRAM for smp bringup:
-------------------------------------------------
-
-Allwinner's A80 SoC uses part of the secure sram for hotplugging of the
-primary core (cpu0). Once the core gets powered up it checks if a magic
-value is set at a specific location. If it is then the BROM will jump
-to the software entry address, instead of executing a standard boot.
-
-Therefore a reserved section sub-node has to be added to the mmio-sram
-declaration.
-
-Note that this is separate from the Allwinner SRAM controller found in
-../../sram/sunxi-sram.txt. This SRAM is secure only and not mappable to
-any device.
-
-Also there are no "secure-only" properties. The implementation should
-check if this SRAM is usable first.
-
-Required sub-node properties:
-- compatible : depending on the SoC this should be one of:
- "allwinner,sun9i-a80-smp-sram"
-
-The rest of the properties should follow the generic mmio-sram discription
-found in ../../misc/sram.txt
-
-Example:
-
- sram_b: sram@20000 {
- /* 256 KiB secure SRAM at 0x20000 */
- compatible = "mmio-sram";
- reg = <0x00020000 0x40000>;
- #address-cells = <1>;
- #size-cells = <1>;
- ranges = <0 0x00020000 0x40000>;
-
- smp-sram@1000 {
- /*
- * This is checked by BROM to determine if
- * cpu0 should jump to SMP entry vector
- */
- compatible = "allwinner,sun9i-a80-smp-sram";
- reg = <0x1000 0x8>;
- };

- };
-
-== Pad Control ==
-
-On Tegra SoCs a pad is a set of pins which are configured as a group.
-The pin grouping is a fixed attribute of the hardware. The PMC can be
-used to set pad power state and signaling voltage. A pad can be either
-in active or power down mode. The support for power state and signaling
-voltage configuration varies depending on the pad in question. 3.3 V and
-1.8 V signaling voltages are supported on pins where software
-controllable signaling voltage switching is available.
-
-The pad configuration state nodes are placed under the pmc node and they
-are referred to by the pinctrl client properties. For more information
-see Documentation/devicetree/bindings/pinctrl/pinctrl-bindings.txt.
-The pad name should be used as the value of the pins property in pin
-configuration nodes.
-
-The following pads are present on Tegra124 and Tegra132:
-audio bb cam comp
-csia csb cse dsi
-dsib dsic dsid hdmi
-hsic hv lvds mipi-bias
-nand pex-bias pex-clk1 pex-clk2
-pex-cntrl sdmmc1 sdmmc3 sdmmc4
-sys_ddc uart usb0 usb1
-usb2 usb_bias
-
-The following pads are present on Tegra210:
-audio audio-hv cam csia
-csib csic csid csie
-csif dbg debug-nonao dmic
-dp dsi dsib dsic
-dsid emmc emmc2 gpio
-hdmi hsic lvds mipi-bias
-pex-bias pex-clk1 pex-clk2 pex-cntrl
-sdmmc1 sdmmc3 spi spi-hv
-uart usb0 usb1 usb2
-usb3 usb-bias
-
-Required pin configuration properties:
- - pins: Must contain name of the pad(s) to be configured.
-
-Optional pin configuration properties:
- - low-power-enable: Configure the pad into power down mode
- - low-power-disable: Configure the pad into active mode
- - power-source: Must contain either TEGRA_IO_PAD_VOLTAGE_1V8
- or TEGRA_IO_PAD_VOLTAGE_3V3 to select between signaling voltages.
- The values are defined in
- include/dt-bindings/pinctrl/pinctrl-tegra-io-pad.h.
-
-Note: The power state can be configured on all of the Tegra124 and
- Tegra132 pads. None of the Tegra124 or Tegra132 pads support
- signaling voltage switching.
-
-Note: All of the listed Tegra210 pads except pex-cntrl support power
- state configuration. Signaling voltage switching is supported on
- following Tegra210 pads: audio, audio-hv, cam, dbg, dmic, gpio,
- pex-cntrl, sdmmc1, sdmmc3, spi, spi-hv, and uart.
-
-Pad configuration state example:
- pmc: pmc@7000e400 {
- compatible = "nvidia,tegra210-pmc";
- reg = <0x0 0x7000e400 0x0 0x400>;
- clocks = <&tegra_car TEGRA210_CLK_PCLK>, <&clk32k_in>;
- clock-names = "pclk", "clk32k_in";
-
- ...
-
- sdmmc1_3v3: sdmmc1-3v3 {
- pins = "sdmmc1";
- power-source = <TEGRA_IO_PAD_VOLTAGE_3V3>;
- };
-
- sdmmc1_1v8: sdmmc1-1v8 {
- pins = "sdmmc1";
- power-source = <TEGRA_IO_PAD_VOLTAGE_1V8>;

-ARM Versatile Express boards family
------------------------------------
-
-ARM's Versatile Express platform consists of a motherboard and one
-or more daughterboards (tiles). The motherboard provides a set of
-peripherals. Processor and RAM "live" on the tiles.
-
-The motherboard and each core tile should be described by a separate
-Device Tree source file, with the tile's description including
-the motherboard file using a /include/ directive. As the motherboard
-can be initialized in one of two different configurations ("memory
-maps"), care must be taken to include the correct one.
-
-
-Root node
----------
-
-Required properties in the root node:
-- compatible value:
- compatible = "arm,vexpress,<model>", "arm,vexpress";
- where <model> is the full tile model name (as used in the tile's
- Technical Reference Manual), eg.:
- - for Coretile Express A5x2 (V2P-CA5s):
- compatible = "arm,vexpress,v2p-ca5s", "arm,vexpress";
- - for Coretile Express A9x4 (V2P-CA9):
- compatible = "arm,vexpress,v2p-ca9", "arm,vexpress";
- If a tile comes in several variants or can be used in more then one
- configuration, the compatible value should be:
- compatible = "arm,vexpress,<model>,<variant>", \
- "arm,vexpress,<model>", "arm,vexpress";
- eg:
- - Coretile Express A15x2 (V2P-CA15) with Tech Chip 1:
- compatible = "arm,vexpress,v2p-ca15,tc1", \
- "arm,vexpress,v2p-ca15", "arm,vexpress";
- - LogicTile Express 13MG (V2F-2XV6) running Cortex-A7 (3 cores) SMM:
- compatible = "arm,vexpress,v2f-2xv6,ca7x3", \
- "arm,vexpress,v2f-2xv6", "arm,vexpress";
-
-Optional properties in the root node:
-- tile model name (use name from the tile's Technical Reference
- Manual, eg. "V2P-CA5s")
- model = "<model>";
-- tile's HBI number (unique ARM's board model ID, visible on the
- PCB's silkscreen) in hexadecimal transcription:
- arm,hbi = <0xhbi>
- eg:
- - for Coretile Express A5x2 (V2P-CA5s) HBI-0191:
- arm,hbi = <0x191>;
- - Coretile Express A9x4 (V2P-CA9) HBI-0225:
- arm,hbi = <0x225>;
-
-
-CPU nodes
----------
-
-Top-level standard "cpus" node is required. It must contain a node
-with device_type = "cpu" property for every available core, eg.:
-
- cpus {
- #address-cells = <1>;
- #size-cells = <0>;
-
- cpu@0 {
- device_type = "cpu";
- compatible = "arm,cortex-a5";
- reg = <0>;
- };
- };
-
-
-Configuration infrastructure
-----------------------------
-
-The platform has an elaborated configuration system, consisting of
-microcontrollers residing on the mother- and daughterboards known
-as Motherboard/Daughterboard Configuration Controller (MCC and DCC).
-The controllers are responsible for the platform initialization
-(reset generation, flash programming, FPGA bitfiles loading etc.)
-but also control clock generators, voltage regulators, gather
-environmental data like temperature, power consumption etc. Even
-the video output switch (FPGA) is controlled that way.
-
-The controllers are not mapped into normal memory address space
-and must be accessed through bridges - other devices capable
-of generating transactions on the configuration bus.
-
-The nodes describing configuration controllers must define
-the following properties:
-- compatible value:
- compatible = "arm,vexpress,config-bus";
-- bridge phandle:
- arm,vexpress,config-bridge = <phandle>;
-and children describing available functions.
-
-
-Platform topology
------------------
-
-As Versatile Express can be configured in number of physically
-different setups, the device tree should describe platform topology.
-Root node and main motherboard node must define the following
-property, describing physical location of the children nodes:
-- site number:
- arm,vexpress,site = <number>;
- where 0 means motherboard, 1 or 2 are daugtherboard sites,
- 0xf means "master" site (site containing main CPU tile)
-- when daughterboards are stacked on one site, their position
- in the stack be be described with:
- arm,vexpress,position = <number>;
-- when describing tiles consisting more than one DCC, its number
- can be described with:
- arm,vexpress,dcc = <number>;
-
-Any of the numbers above defaults to zero if not defined in
-the node or any of its parent.
-
-
-Motherboard
------------
-
-The motherboard description file provides a single "motherboard" node
-using 2 address cells corresponding to the Static Memory Bus used
-between the motherboard and the tile. The first cell defines the Chip
-Select (CS) line number, the second cell address offset within the CS.
-All interrupt lines between the motherboard and the tile are active
-high and are described using single cell.
-
-Optional properties of the "motherboard" node:
-- motherboard's memory map variant:
- arm,v2m-memory-map = "<name>";
- where name is one of:
- - "rs1" - for RS1 map (i.a. peripherals on CS3); this map is also
- referred to as "ARM Cortex-A Series memory map":
- arm,v2m-memory-map = "rs1";
- When this property is missing, the motherboard is using the original
- memory map (also known as the "Legacy memory map", primarily used
- with the original CoreTile Express A9x4) with peripherals on CS7.
-
-Motherboard .dtsi files provide a set of labelled peripherals that
-can be used to obtain required phandle in the tile's "aliases" node:
-- UARTs, note that the numbers correspond to the physical connectors
- on the motherboard's back panel:
- v2m_serial0, v2m_serial1, v2m_serial2 and v2m_serial3
-- I2C controllers:
- v2m_i2c_dvi and v2m_i2c_pcie
-- SP804 timers:
- v2m_timer01 and v2m_timer23
-
-The tile description should define a "smb" node, describing the
-Static Memory Bus between the tile and motherboard. It must define
-the following properties:
-- "simple-bus" compatible value (to ensure creation of the children)
- compatible = "simple-bus";
-- mapping of the SMB CS/offset addresses into main address space:
- #address-cells = <2>;
- #size-cells = <1>;
- ranges = <...>;
-- interrupts mapping:
- #interrupt-cells = <1>;
- interrupt-map-mask = <0 0 63>;
- interrupt-map = <...>;
-

-- interrupts: interrupt for the block
-- reg: registers and size for the block
-
-Optional properties:
-- clocks: a SoC clock running the peripheral.
-- clock-names: should be set to "PCLK" for the peripheral clock.
-
-Required properties for "cortina,gemini-pata" compatible:

+ (MWDM) modes 0 through 2 and Ultra DMA modes 0 through 6.
+
+ On the Gemini platform, this PATA block is accompanied by a PATA to
+ SATA bridge in order to support SATA. This is why a phandle to that
+ controller is compulsory on that platform.
+
+ The timing properties are unique per-SoC, not per-board.

-* Calxeda AHCI SATA Controller
-
-SATA nodes are defined to describe on-chip Serial ATA controllers.
-The Calxeda SATA controller mostly conforms to the AHCI interface
-with some special extensions to add functionality.
-Each SATA controller should have its own node.
-
-Required properties:
-- compatible : compatible list, contains "calxeda,hb-ahci"
-- interrupts : <interrupt mapping for SATA IRQ>
-- reg : <registers mapping>
-
-Optional properties:
-- dma-coherent : Present if dma operations are coherent
-- calxeda,port-phys : phandle-combophy and lane assignment, which maps each
- SATA port to a combophy and a lane within that
- combophy
-- calxeda,sgpio-gpio: phandle-gpio bank, bit offset, and default on or off,
- which indicates that the driver supports SGPIO
- indicator lights using the indicated GPIOs
-- calxeda,led-order : a u32 array that map port numbers to offsets within the
- SGPIO bitstream.
-- calxeda,tx-atten : a u32 array that contains TX attenuation override
- codes, one per port. The upper 3 bytes are always
- 0 and thus ignored.
-- calxeda,pre-clocks : a u32 that indicates the number of additional clock
- cycles to transmit before sending an SGPIO pattern
-- calxeda,post-clocks: a u32 that indicates the number of additional clock
- cycles to transmit after sending an SGPIO pattern
-
-Example:
- sata@ffe08000 {

-Renesas Bus State Controller (BSC)
-==================================
-
-The Renesas Bus State Controller (BSC, sometimes called "LBSC within Bus
-Bridge", or "External Bus Interface") can be found in several Renesas ARM SoCs.
-It provides an external bus for connecting multiple external devices to the
-SoC, driving several chip select lines, for e.g. NOR FLASH, Ethernet and USB.
-
-While the BSC is a fairly simple memory-mapped bus, it may be part of a PM
-domain, and may have a gateable functional clock.
-Before a device connected to the BSC can be accessed, the PM domain
-containing the BSC must be powered on, and the functional clock
-driving the BSC must be enabled.
-
-The bindings for the BSC extend the bindings for "simple-pm-bus".
-
-
-Required properties
- - compatible: Must contain an SoC-specific value, and "renesas,bsc" and
- "simple-pm-bus" as fallbacks.
- SoC-specific values can be:
- "renesas,bsc-r8a73a4" for R-Mobile APE6 (r8a73a4)
- "renesas,bsc-sh73a0" for SH-Mobile AG5 (sh73a0)
- - #address-cells, #size-cells, ranges: Must describe the mapping between
- parent address and child address spaces.
- - reg: Must contain the base address and length to access the bus controller.
-
-Optional properties:
- - interrupts: Must contain a reference to the BSC interrupt, if available.
- - clocks: Must contain a reference to the functional clock, if available.
- - power-domains: Must contain a reference to the PM domain, if available.

-Simple Power-Managed Bus
-========================
-
-A Simple Power-Managed Bus is a transparent bus that doesn't need a real
-driver, as it's typically initialized by the boot loader.
-
-However, its bus controller is part of a PM domain, or under the control of a
-functional clock. Hence, the bus controller's PM domain and/or clock must be
-enabled for child devices connected to the bus (either on-SoC or externally)
-to function.
-
-While "simple-pm-bus" follows the "simple-bus" set of properties, as specified
-in the Devicetree Specification, it is not an extension of "simple-bus".
-
-
-Required properties:
- - compatible: Must contain at least "simple-pm-bus".
- Must not contain "simple-bus".
- It's recommended to let this be preceded by one or more
- vendor-specific compatible values.
- - #address-cells, #size-cells, ranges: Must describe the mapping between
- parent address and child address spaces.
-
-Optional platform-specific properties for clock or PM domain control (at least
-one of them is required):
- - clocks: Must contain a reference to the functional clock(s),
- - power-domains: Must contain a reference to the PM domain.
-Please refer to the binding documentation for the clock and/or PM domain
-providers for more details.
-
-
-Example:
-
- bsc: bus@fec10000 {
- compatible = "renesas,bsc-sh73a0", "renesas,bsc",
- "simple-pm-bus";
- #address-cells = <1>;
- #size-cells = <1>;
- ranges = <0 0 0x20000000>;
- reg = <0xfec10000 0x400>;

+
+description: |
+ The UniPhier System Bus is an external bus that connects on-board devices to
+ the UniPhier SoC. It is a simple (semi-)parallel bus with address, data, and
+ some control signals. It supports up to 8 banks (chip selects).
+
+ Before any access to the bus, the bus controller must be configured; the bus
+ controller registers provide the control for the translation from the offset
+ within each bank to the CPU-viewed address. The needed setup includes the
+ base address, the size of each bank. Optionally, some timing parameters can
+ be optimized for faster bus access.

-UniPhier System Bus
-
-The UniPhier System Bus is an external bus that connects on-board devices to
-the UniPhier SoC. It is a simple (semi-)parallel bus with address, data, and
-some control signals. It supports up to 8 banks (chip selects).
-
-Before any access to the bus, the bus controller must be configured; the bus
-controller registers provide the control for the translation from the offset
-within each bank to the CPU-viewed address. The needed setup includes the base
-address, the size of each bank. Optionally, some timing parameters can be
-optimized for faster bus access.
-
-Required properties:
-- compatible: should be "socionext,uniphier-system-bus".
-- reg: offset and length of the register set for the bus controller device.
-- #address-cells: should be 2. The first cell is the bank number (chip select).
- The second cell is the address offset within the bank.
-- #size-cells: should be 1.
-- ranges: should provide a proper address translation from the System Bus to
- the parent bus.
-
-Note:
-The address region(s) that can be assigned for the System Bus is implementation
-defined. Some SoCs can use 0x00000000-0x0fffffff and 0x40000000-0x4fffffff,

-There is no reason to stick to a particular translation mapping, but the
-"ranges" property should provide a "reasonable" default that is known to work.
-The software should initialize the bus controller according to it.

+description: |
+ The ICS525 and ICS307 oscillators are produced by Integrated
+ Devices Technology (IDT). ARM integrated these oscillators deeply into their
+ reference designs by adding special control registers that manage such
+ oscillators to their system controllers.
+
+ The various ARM system controllers contain logic to serialize and initialize
+ an ICST clock request after a write to the 32 bit register at an offset
+ into the system controller. Furthermore, to even be able to alter one of
+ these frequencies, the system controller must first be unlocked by
+ writing a special token to another offset in the system controller.
+
+ Some ARM hardware contain special versions of the serial interface that only
+ connects the low 8 bits of the VDW (missing one bit), hard-wires RDW to
+ different values and sometimes also hard-wires the output divider. They
+ therefore have special compatible strings as per this table (the OD value is
+ the value on the pins, not the resulting output divider).
+
+ In the core modules and logic tiles, the ICST is a configurable clock fed
+ from a 24 MHz clock on the motherboard (usually the main crystal) used for
+ generating e.g. video clocks. It is located on the core module and there is
+ only one of these. This clock node must be a subnode of the core module.

+description: |
+ Clocks Control Unit is the core of Baikal-T1 SoC System Controller
+ responsible for the chip subsystems clocking and resetting. The CCU is
+ connected with an external fixed rate oscillator, which signal is transformed
+ into clocks of various frequencies and then propagated to either individual
+ IP-blocks or to groups of blocks (clock domains). The transformation is done
+ by means of an embedded into CCU PLLs and gateable/non-gateable dividers. The
+ later ones are described in this binding. Each clock domain can be also
+ individually reset by using the domain clocks divider configuration
+ registers. Baikal-T1 CCU is logically divided into the next components:
+ 1) External oscillator (normally XTAL's 25 MHz crystal oscillator, but
+ in general can provide any frequency supported by the CCU PLLs).
+ 2) PLLs clocks generators (PLLs).
+ 3) AXI-bus clock dividers (AXI) - described in this binding file.
+ 4) System devices reference clock dividers (SYS) - described in this binding
+ file.
+ which are connected with each other as shown on the next figure:
+
+ +---------------+
+ | Baikal-T1 CCU |
+ | +----+------|- MIPS P5600 cores
+ | +-|PLLs|------|- DDR controller
+ | | +----+ |
+ +----+ | | | | |
+ |XTAL|--|-+ | | +---+-|
+ +----+ | | | +-|AXI|-|- AXI-bus
+ | | | +---+-|
+ | | | |
+ | | +----+---+-|- APB-bus
+ | +-------|SYS|-|- Low-speed Devices
+ | +---+-|- High-speed Devices
+ +---------------+
+
+ Each sub-block is represented as a separate DT node and has an individual
+ driver to be bound with.
+
+ In order to create signals of wide range frequencies the external oscillator
+ output is primarily connected to a set of CCU PLLs. Some of PLLs CLKOUT are
+ then passed over CCU dividers to create signals required for the target clock
+ domain (like AXI-bus or System Device consumers). The dividers have the
+ following structure:
+
+ +--------------+
+ CLKIN --|->+----+ 1|\ |
+ SETCLK--|--|/DIV|->| | |
+ CLKDIV--|--| | | |-|->CLKLOUT
+ LOCK----|--+----+ | | |
+ | |/ |
+ | | |
+ EN------|-----------+ |
+ RST-----|--------------|->RSTOUT
+ +--------------+
+
+ where CLKIN is the reference clock coming either from CCU PLLs or from an
+ external clock oscillator, SETCLK - a command to update the output clock in
+ accordance with a set divider, CLKDIV - clocks divider, LOCK - a signal of
+ the output clock stabilization, EN - enable/disable the divider block,
+ RST/RSTOUT - reset clocks domain signal. Depending on the consumer IP-core
+ peculiarities the dividers may lack of some functionality depicted on the
+ figure above (like EN, CLKDIV/LOCK/SETCLK). In this case the corresponding
+ clock provider just doesn't expose either switching functions, or the rate
+ configuration, or both of them.
+
+ The clock dividers, which output clock is then consumed by the SoC individual
+ devices, are united into a single clocks provider called System Devices CCU.
+ Similarly the dividers with output clocks utilized as AXI-bus reference clocks
+ are called AXI-bus CCU. Both of them use the common clock bindings with no
+ custom properties. The list of exported clocks and reset signals can be found
+ in the files: 'include/dt-bindings/clock/bt1-ccu.h' and
+ 'include/dt-bindings/reset/bt1-ccu.h'. Since System Devices and AXI-bus CCU
+ are a part of the Baikal-T1 SoC System Controller their DT nodes are supposed
+ to be a children of later one.

+ +---------------+
+
+ Each CCU sub-block is represented as a separate dts-node and has an
+ individual driver to be bound with.
+
+ In order to create signals of wide range frequencies the external oscillator
+ output is primarily connected to a set of CCU PLLs. There are five PLLs
+ to create a clock for the MIPS P5600 cores, the embedded DDR controller,
+ SATA, Ethernet and PCIe domains. The last three domains though named by the
+ biggest system interfaces in fact include nearly all of the rest SoC
+ peripherals. Each of the PLLs is based on True Circuits TSMC CLN28HPM core
+ with an interface wrapper (so called safe PLL' clocks switcher) to simplify
+ the PLL configuration procedure. The PLLs work as depicted on the next
+ diagram:
+

+ | | ^
+ Rclk-+->+---+ | |
+ CLKR--->|/NR|-+ |
+ +---+ |
+ BYPASS--------------------------------------+
+ BWADJ--->
+
+ where Rclk is the reference clock coming from XTAL, NR - reference clock
+ divider, NF - PLL clock multiplier, OD - VCO output clock divider, CLKOUT -
+ output clock, BWADJ is the PLL bandwidth adjustment parameter. At this moment
+ the binding supports the PLL dividers configuration in accordance with a
+ requested rate, while bypassing and bandwidth adjustment settings can be
+ added in future if it gets to be necessary.
+
+ The PLLs CLKOUT is then either directly connected with the corresponding
+ clocks consumer (like P5600 cores or DDR controller) or passed over a CCU
+ divider to create a signal required for the clock domain.
+
+ The CCU PLL dts-node uses the common clock bindings with no custom
+ parameters. The list of exported clocks can be found in
+ 'include/dt-bindings/clock/bt1-ccu.h'. Since CCU PLL is a part of the
+ Baikal-T1 SoC System Controller its DT node is supposed to be a child of
+ later one.

-* Clock bindings for Freescale i.MX7ULP
-
-i.MX7ULP Clock functions are under joint control of the System
-Clock Generation (SCG) modules, Peripheral Clock Control (PCC)
-modules, and Core Mode Controller (CMC)1 blocks
-
-The clocking scheme provides clear separation between M4 domain
-and A7 domain. Except for a few clock sources shared between two
-domains, such as the System Oscillator clock, the Slow IRC (SIRC),
-and and the Fast IRC clock (FIRCLK), clock sources and clock
-management are separated and contained within each domain.
-
-M4 clock management consists of SCG0, PCC0, PCC1, and CMC0 modules.
-A7 clock management consists of SCG1, PCC2, PCC3, and CMC1 modules.
-
-Note: this binding doc is only for A7 clock domain.
-
-System Clock Generation (SCG) modules:
----------------------------------------------------------------------
-The System Clock Generation (SCG) is responsible for clock generation
-and distribution across this device. Functions performed by the SCG
-include: clock reference selection, generation of clock used to derive
-processor, system, peripheral bus and external memory interface clocks,
-source selection for peripheral clocks and control of power saving
-clock gating mode.
-
-Required properties:
-
-- compatible: Should be "fsl,imx7ulp-scg1".
-- reg : Should contain registers location and length.
-- #clock-cells: Should be <1>.
-- clocks: Should contain the fixed input clocks.
-- clock-names: Should contain the following clock names:
- "rosc", "sosc", "sirc", "firc", "upll", "mpll".
-
-Peripheral Clock Control (PCC) modules:
----------------------------------------------------------------------
-The Peripheral Clock Control (PCC) is responsible for clock selection,
-optional division and clock gating mode for peripherals in their
-respected power domain
-
-Required properties:
-- compatible: Should be one of:
- "fsl,imx7ulp-pcc2",
- "fsl,imx7ulp-pcc3".
-- reg : Should contain registers location and length.
-- #clock-cells: Should be <1>.
-- clocks: Should contain the fixed input clocks.
-- clock-names: Should contain the following clock names:
- "nic1_bus_clk", "nic1_clk", "ddr_clk", "apll_pfd2",
- "apll_pfd1", "apll_pfd0", "upll", "sosc_bus_clk",
- "mpll", "firc_bus_clk", "rosc", "spll_bus_clk";
-
-The clock consumer should specify the desired clock by having the clock
-ID in its "clocks" phandle cell.

-Ingenic SoC CGU binding
-
-The CGU in an Ingenic SoC provides all the clocks generated on-chip. It
-typically includes a variety of PLLs, multiplexers, dividers & gates in order
-to provide many different clock signals derived from only 2 external source
-clocks.
-
-Required properties:
-- compatible : Should be one of:
- * ingenic,jz4740-cgu
- * ingenic,jz4725b-cgu
- * ingenic,jz4770-cgu
- * ingenic,jz4780-cgu
-- reg : The address & length of the CGU registers.
-- clocks : List of phandle & clock specifiers for clocks external to the CGU.
- Two such external clocks should be specified - first the external crystal
- "ext" and second the RTC clock source "rtc".
-- clock-names : List of name strings for the external clocks.
-- #clock-cells: Should be 1.
- Clock consumers specify this argument to identify a clock. The valid values
- may be found in <dt-bindings/clock/<soctype>-cgu.h>.

-Example SoC include file:
-
-/ {
- cgu: jz4740-cgu {

- "mpmu", "apmu", "apbc". So three reg spaces need to be defined.
-
-- #clock-cells: should be 1.
-- #reset-cells: should be 1.
-
-Each clock is assigned an identifier and client nodes use this identifier
-to specify the clock which they consume.
-
-All these identifiers could be found in <dt-bindings/clock/marvell,mmp2.h>.

-* Renesas CPG Module Stop (MSTP) Clocks
-
-The CPG can gate SoC device clocks. The gates are organized in groups of up to
-32 gates.
-
-This device tree binding describes a single 32 gate clocks group per node.
-Clocks are referenced by user nodes by the MSTP node phandle and the clock
-index in the group, from 0 to 31.
-
-Required Properties:
-
- - compatible: Must be one of the following
- - "renesas,r7s72100-mstp-clocks" for R7S72100 (RZ) MSTP gate clocks
- - "renesas,r8a73a4-mstp-clocks" for R8A73A4 (R-Mobile APE6) MSTP gate clocks
- - "renesas,r8a7740-mstp-clocks" for R8A7740 (R-Mobile A1) MSTP gate clocks
- - "renesas,r8a7778-mstp-clocks" for R8A7778 (R-Car M1) MSTP gate clocks
- - "renesas,r8a7779-mstp-clocks" for R8A7779 (R-Car H1) MSTP gate clocks
- - "renesas,r8a7790-mstp-clocks" for R8A7790 (R-Car H2) MSTP gate clocks
- - "renesas,r8a7791-mstp-clocks" for R8A7791 (R-Car M2-W) MSTP gate clocks
- - "renesas,r8a7792-mstp-clocks" for R8A7792 (R-Car V2H) MSTP gate clocks
- - "renesas,r8a7793-mstp-clocks" for R8A7793 (R-Car M2-N) MSTP gate clocks
- - "renesas,r8a7794-mstp-clocks" for R8A7794 (R-Car E2) MSTP gate clocks
- - "renesas,sh73a0-mstp-clocks" for SH73A0 (SH-MobileAG5) MSTP gate clocks
- and "renesas,cpg-mstp-clocks" as a fallback.
- - reg: Base address and length of the I/O mapped registers used by the MSTP
- clocks. The first register is the clock control register and is mandatory.
- The second register is the clock status register and is optional when not
- implemented in hardware.
- - clocks: Reference to the parent clocks, one per output clock. The parents
- must appear in the same order as the output clocks.
- - #clock-cells: Must be 1
- - clock-output-names: The name of the clocks as free-form strings
- - clock-indices: Indices of the gate clocks into the group (0 to 31)
-
-The clocks, clock-output-names and clock-indices properties contain one entry
-per gate clock. The MSTP groups are sparsely populated. Unimplemented gate
-clocks must not be declared.
-

+title: Renesas Clock Pulse Generator (CPG) Module Stop (MSTP) Clocks
+
+maintainers:
+ - Geert Uytterhoeven <geert+renesas@glider.be>
+
+description:
+ The Clock Pulse Generator (CPG) can gate SoC device clocks. The gates are
+ organized in groups of up to 32 gates.
+
+ This device tree binding describes a single 32 gate clocks group per node.
+ Clocks are referenced by user nodes by the Module Stop (MSTP) node phandle
+ and the clock index in the group, from 0 to 31.

-Required properties:
-- compatible: Should be "sifive,<chip>-prci". Only one value is
- supported: "sifive,fu540-c000-prci"
-- reg: Should describe the PRCI's register target physical address region
-- clocks: Should point to the hfclk device tree node and the rtcclk
- device tree node. The RTC clock here is not a time-of-day clock,
- but is instead a high-stability clock source for system timers
- and cycle counters.
-- #clock-cells: Should be <1>

-The clock consumer should specify the desired clock via the clock ID
-macros defined in include/dt-bindings/clock/sifive-fu540-prci.h.
-These macros begin with PRCI_CLK_.

-The hfclk and rtcclk nodes are required, and represent physical

The Si5341 and Si5340 are programmable i2c clock generators with up to 10 output
clocks. The chip contains a PLL that sources 5 (or 4) multisynth clocks, which
in turn can be directed to any of the 10 (or 4) outputs through a divider.
The internal structure of the clock generators can be found in [2].
+The Si5345 is similar to the Si5341 with the addition of fractional input
+dividers and automatic input selection, as described in [3].
+The Si5342 and Si5344 are smaller versions of the Si5345, with 2 or 4 outputs.

-=======================================
-
-Device nodes should specify the reset channel required in their "resets"
-property, containing a phandle to the reset device node and an index specifying

-The index is the bit number within the RCC registers bank, starting from RCC

-It is calculated as: index = register_offset / 4 * 32 + bit_offset.
-Where bit_offset is the bit offset within the register.
-
-For example on STM32MP1, for LTDC reset:
- ltdc = APB4_RSTSETR_offset / 4 * 32 + LTDC_bit_offset

-Required properties for all clocks:
-- reg : shall be the control register address for the clock.
-- clocks : shall be the input parent clock(s) phandle for the clock. For
- multiplexed clocks, the list order must match the hardware
- programming order.
-- #clock-cells : from common clock binding; shall be set to 0 except for
- the following compatibles where it shall be set to 1:
- "allwinner,*-gates-clk", "allwinner,sun4i-pll5-clk",
- "allwinner,sun4i-pll6-clk", "allwinner,sun6i-a31-pll6-clk",
- "allwinner,*-usb-clk", "allwinner,*-mmc-clk",
- "allwinner,*-mmc-config-clk"
-- clock-output-names : shall be the corresponding names of the outputs.
- If the clock module only has one output, the name shall be the
- module name.
-
-And "allwinner,*-usb-clk" clocks also require:
-- reset-cells : shall be set to 1
-
-The "allwinner,sun4i-a10-ve-clk" clock also requires:
-- reset-cells : shall be set to 0
-
-The "allwinner,sun9i-a80-mmc-config-clk" clock also requires:
-- #reset-cells : shall be set to 1
-- resets : shall be the reset control phandle for the mmc block.
-
-For "allwinner,sun7i-a20-gmac-clk", the parent clocks shall be fixed rate
-dummy clocks at 25 MHz and 125 MHz, respectively. See example.
-
-Clock consumers should specify the desired clocks they use with a
-"clocks" phandle cell. Consumers that are using a gated clock should
-provide an additional ID in their clock property. This ID is the
-offset of the bit controlling this particular gate in the register.
-For the other clocks with "#clock-cells" = 1, the additional ID shall
-refer to the index of the output.
-
-For "allwinner,sun6i-a31-pll6-clk", there are 2 outputs. The first output
-is the normal PLL6 output, or "pll6". The second output is rate doubled
-PLL6, or "pll6x2".
-
-The "allwinner,*-mmc-clk" clocks have three different outputs: the
-main clock, with the ID 0, and the output and sample clocks, with the
-IDs 1 and 2, respectively.
-
-The "allwinner,sun9i-a80-mmc-config-clk" clock has one clock/reset output
-per mmc controller. The number of outputs is determined by the size of
-the address block, which is related to the overall mmc block.

-Samsung micro-USB 11-pin connector
-==================================
-
-Samsung micro-USB 11-pin connector is an extension of micro-USB connector.
-It is present in multiple Samsung mobile devices.
-It has additional pins to route MHL traffic simultanously with USB.
-
-The bindings are superset of usb-connector bindings for micro-USB connector[1].
-
-Required properties:
-- compatible: must be: "samsung,usb-connector-11pin", "usb-b-connector",
-- type: must be "micro".
-
-Required nodes:
-- any data bus to the connector should be modeled using the OF graph bindings
- specified in bindings/graph.txt, unless the bus is between parent node and
- the connector. Since single connector can have multpile data buses every bus
- has assigned OF graph port number as follows:
- 0: High Speed (HS),
- 3: Mobile High-Definition Link (MHL), specific to 11-pin Samsung micro-USB.

-STMicroelectronics STM32 Low-Power Timer quadrature encoder and counter
-
-STM32 Low-Power Timer provides several counter modes. It can be used as:
-- quadrature encoder to detect angular position and direction of rotary
- elements, from IN1 and IN2 input signals.
-- simple counter from IN1 input signal.
-
-Must be a sub-node of an STM32 Low-Power Timer device tree node.
-See ../mfd/stm32-lptimer.txt for details about the parent node.
-
-Required properties:
-- compatible: Must be "st,stm32-lptimer-counter".
-- pinctrl-names: Set to "default". An additional "sleep" state can be
- defined to set pins in sleep state.
-- pinctrl-n: List of phandles pointing to pin configuration nodes,
- to set IN1/IN2 pins in mode of operation for Low-Power
- Timer input on external pin.
-
-Example:
- timer@40002400 {
- compatible = "st,stm32-lptimer";
- ...
- counter {
- compatible = "st,stm32-lptimer-counter";
- pinctrl-names = "default", "sleep";
- pinctrl-0 = <&lptim1_in_pins>;
- pinctrl-1 = <&lptim1_sleep_in_pins>;

+
+description: |
+ The display engine pipeline (and its entry point, since it can be
+ either directly the backend or the frontend) is represented as an
+ extra node.
+
+ The Allwinner A10 Display pipeline is composed of several components
+ that are going to be documented below:
+
+ For all connections between components up to the TCONs in the
+ display pipeline, when there are multiple components of the same
+ type at the same depth, the local endpoint ID must be the same as
+ the remote component's index. For example, if the remote endpoint is
+ Frontend 1, then the local endpoint ID must be 1.
+
+ Frontend 0 [0] ------- [0] Backend 0 [0] ------- [0] TCON 0
+ [1] -- -- [1] [1] -- -- [1]
+ \ / \ /
+ X X
+ / \ / \
+ [0] -- -- [0] [0] -- -- [0]
+ Frontend 1 [1] ------- [1] Backend 1 [1] ------- [1] TCON 1
+
+ For a two pipeline system such as the one depicted above, the lines
+ represent the connections between the components, while the numbers
+ within the square brackets corresponds to the ID of the local endpoint.
+
+ The same rule also applies to DE 2.0 mixer-TCON connections:
+
+ Mixer 0 [0] ----------- [0] TCON 0
+ [1] ---- ---- [1]
+ \ /
+ X
+ / \
+ [0] ---- ---- [0]

+description: |
+ TCON TOPs main purpose is to configure whole display pipeline. It
+ determines relationships between mixers and TCONs, selects source
+ TCON for HDMI, muxes LCD and TV encoder GPIO output, selects TV
+ encoder clock source and contains additional TV TCON and DSI gates.
+
+ It allows display pipeline to be configured in very different ways:
+
+ / LCD0/LVDS0
+ / [0] TCON-LCD0
+ | \ MIPI DSI
+ mixer0 |
+ \ / [1] TCON-LCD1 - LCD1/LVDS1
+ TCON-TOP
+ / \ [2] TCON-TV0 [0] - TVE0/RGB
+ mixer1 | \
+ | TCON-TOP - HDMI
+ | /
+ \ [3] TCON-TV1 [1] - TVE1/RGB
+
+ Note that both TCON TOP references same physical unit. Both mixers
+ can be connected to any TCON. Not all TCON TOP variants support all
+ features.

+description: |
+ The IT6505 is a high-performance DisplayPort 1.1a transmitter,
+ fully compliant with DisplayPort 1.1a, HDCP 1.3 specifications.
+ The IT6505 supports color depth of up to 36 bits (12 bits/color)
+ and ensures robust transmission of high-quality uncompressed video
+ content, along with uncompressed and compressed digital audio content.
+
+ Aside from the various video output formats supported, the IT6505
+ also encodes and transmits up to 8 channels of I2S digital audio,
+ with sampling rate up to 192kHz and sample size up to 24 bits.
+ In addition, an S/PDIF input port takes in compressed audio of up to
+ 192kHz frame rate.
+
+ Each IT6505 chip comes preprogrammed with an unique HDCP key,
+ in compliance with the HDCP 1.3 standard so as to provide secure
+ transmission of high-definition content. Users of the IT6505 need not
+ purchase any HDCP keys or ROMs.

-Renesas R-Car LVDS Encoder
-==========================
-
-These DT bindings describe the LVDS encoder embedded in the Renesas R-Car
-Gen2, R-Car Gen3 and RZ/G SoCs.
-
-Required properties:
-
-- compatible : Shall contain one of
- - "renesas,r8a7743-lvds" for R8A7743 (RZ/G1M) compatible LVDS encoders
- - "renesas,r8a7744-lvds" for R8A7744 (RZ/G1N) compatible LVDS encoders

- - "renesas,r8a7790-lvds" for R8A7790 (R-Car H2) compatible LVDS encoders
- - "renesas,r8a7791-lvds" for R8A7791 (R-Car M2-W) compatible LVDS encoders
- - "renesas,r8a7793-lvds" for R8A7793 (R-Car M2-N) compatible LVDS encoders
- - "renesas,r8a7795-lvds" for R8A7795 (R-Car H3) compatible LVDS encoders
- - "renesas,r8a7796-lvds" for R8A7796 (R-Car M3-W) compatible LVDS encoders
- - "renesas,r8a77965-lvds" for R8A77965 (R-Car M3-N) compatible LVDS encoders

- - "renesas,r8a77990-lvds" for R8A77990 (R-Car E3) compatible LVDS encoders
- - "renesas,r8a77995-lvds" for R8A77995 (R-Car D3) compatible LVDS encoders
-
-- reg: Base address and length for the memory-mapped registers
-- clocks: A list of phandles + clock-specifier pairs, one for each entry in
- the clock-names property.
-- clock-names: Name of the clocks. This property is model-dependent.
- - The functional clock, which mandatory for all models, shall be listed
- first, and shall be named "fck".
- - On R8A77990, R8A77995 and R8A774C0, the LVDS encoder can use the EXTAL or
- DU_DOTCLKINx clocks. Those clocks are optional. When supplied they must be
- named "extal" and "dclkin.x" respectively, with "x" being the DU_DOTCLKIN
- numerical index.
- - When the clocks property only contains the functional clock, the
- clock-names property may be omitted.
-- resets: A phandle + reset specifier for the module reset
-
-Required nodes:
-
-The LVDS encoder has two video ports. Their connections are modelled using the
-OF graph bindings specified in Documentation/devicetree/bindings/graph.txt.
-
-- Video port 0 corresponds to the parallel RGB input
-- Video port 1 corresponds to the LVDS output
-
-Each port shall have a single endpoint.
-
-Optional properties:
-
-- renesas,companion : phandle to the companion LVDS encoder. This property is
- mandatory for the first LVDS encoder on D3 and E3 SoCs, and shall point to
- the second encoder to be used as a companion in dual-link mode. It shall not
- be set for any other LVDS encoder.
-
-
-Example:
-
- lvds0: lvds@feb90000 {
- compatible = "renesas,r8a77990-lvds";
- reg = <0 0xfeb90000 0 0x20>;
- clocks = <&cpg CPG_MOD 727>;
- power-domains = <&sysc R8A77990_PD_ALWAYS_ON>;
- resets = <&cpg 727>;
-
- renesas,companion = <&lvds1>;
-
- ports {
- #address-cells = <1>;
- #size-cells = <0>;
-
- port@0 {
- reg = <0>;
- lvds0_in: endpoint {
- remote-endpoint = <&du_out_lvds0>;
- };
- };
- port@1 {
- reg = <1>;
- lvds0_out: endpoint {
- };
- };
- };
- };

+title: Common Properties for DSI Display Panels
+
+maintainers:
+ - Linus Walleij <linus.walleij@linaro.org>
+
+description: |
+ This document defines device tree properties common to DSI, Display
+ Serial Interface controllers and attached panels. It doesn't constitute
+ a device tree binding specification by itself but is meant to be referenced
+ by device tree bindings.
+
+ When referenced from panel device tree bindings the properties defined in
+ this document are defined as follows. The panel device tree bindings are
+ responsible for defining whether each property is required or optional.
+
+ Notice: this binding concerns DSI panels connected directly to a master
+ without any intermediate port graph to the panel. Each DSI master
+ can control one to four virtual channels to one panel. Each virtual
+ channel should have a node "panel" for their virtual channel with their
+ reg-property set to the virtual channel number, usually there is just
+ one virtual channel, number 0.

+ properties:
+ reg:
+ minimum: 0
+ maximum: 3
+ description:
+ The virtual channel number of a DSI peripheral. Must be in the range
+ from 0 to 3, as DSI uses a 2-bit addressing scheme. Some DSI
+ peripherals respond to more than a single virtual channel. In that
+ case the reg property can take multiple entries, one for each virtual
+ channel that the peripheral responds to.
+
+ clock-master:
+ type: boolean
+ description:
+ Should be enabled if the host is being used in conjunction with
+ another DSI host to drive the same peripheral. Hardware supporting
+ such a configuration generally requires the data on both the busses
+ to be driven by the same clock. Only the DSI host instance
+ controlling this clock should contain this property.
+
+ enforce-video-mode:
+ type: boolean
+ description:
+ The best option is usually to run a panel in command mode, as this
+ gives better control over the panel hardware. However for different
+ reasons like broken hardware, missing features or testing, it may be
+ useful to be able to force a command mode-capable panel into video
+ mode.

-Vivante GPU core devices
-========================
-
-Required properties:
-- compatible: Should be "vivante,gc"
- A more specific compatible is not needed, as the cores contain chip
- identification registers at fixed locations, which provide all the
- necessary information to the driver.
-- reg: should be register base and length as documented in the
- datasheet
-- interrupts: Should contain the cores interrupt line
-- clocks: should contain one clock for entry in clock-names
- see Documentation/devicetree/bindings/clock/clock-bindings.txt
-- clock-names:
- - "bus": AXI/master interface clock
- - "reg": AHB/slave interface clock
- (only required if GPU can gate slave interface independently)
- - "core": GPU core clock
- - "shader": Shader clock (only required if GPU has feature PIPE_3D)
-
-Optional properties:
-- power-domains: a power domain consumer specifier according to
- Documentation/devicetree/bindings/power/power_domain.txt
-
-example:
-
-gpu_3d: gpu@130000 {
- compatible = "vivante,gc";
- reg = <0x00130000 0x4000>;
- interrupts = <0 9 IRQ_TYPE_LEVEL_HIGH>;
- clocks = <&clks IMX6QDL_CLK_GPU3D_AXI>,

-display-timing bindings
-=======================
-
-display-timings node
---------------------
-
-required properties:
- - none
-
-optional properties:
- - native-mode: The native mode for the display, in case multiple modes are
- provided. When omitted, assume the first node is the native.
-
-timing subnode
---------------
-
-required properties:
- - hactive, vactive: display resolution
- - hfront-porch, hback-porch, hsync-len: horizontal display timing parameters
- in pixels
- vfront-porch, vback-porch, vsync-len: vertical display timing parameters in
- lines
- - clock-frequency: display clock in Hz
-
-optional properties:
- - hsync-active: hsync pulse is active low/high/ignored
- - vsync-active: vsync pulse is active low/high/ignored
- - de-active: data-enable pulse is active low/high/ignored
- - pixelclk-active: with
- - active high = drive pixel data on rising edge/
- sample data on falling edge
- - active low = drive pixel data on falling edge/
- sample data on rising edge
- - ignored = ignored
- - syncclk-active: with
- - active high = drive sync on rising edge/
- sample sync on falling edge of pixel
- clock
- - active low = drive sync on falling edge/
- sample sync on rising edge of pixel
- clock
- - omitted = same configuration as pixelclk-active
- - interlaced (bool): boolean to enable interlaced mode
- - doublescan (bool): boolean to enable doublescan mode
- - doubleclk (bool): boolean to enable doubleclock mode
-
-All the optional properties that are not bool follow the following logic:
- <1>: high active
- <0>: low active
- omitted: not used on hardware
-
-There are different ways of describing the capabilities of a display. The
-devicetree representation corresponds to the one commonly found in datasheets
-for displays. If a display supports multiple signal timings, the native-mode
-can be specified.
-
-The parameters are defined as:
-
- +----------+-------------------------------------+----------+-------+
- | | ^ | | |
- | | |vback_porch | | |
- | | v | | |
- +----------#######################################----------+-------+
- | # ^ # | |
- | # | # | |
- | hback # | # hfront | hsync |
- | porch # | hactive # porch | len |
- |<-------->#<-------+--------------------------->#<-------->|<----->|
- | # | # | |
- | # |vactive # | |
- | # | # | |
- | # v # | |
- +----------#######################################----------+-------+
- | | ^ | | |
- | | |vfront_porch | | |
- | | v | | |
- +----------+-------------------------------------+----------+-------+
- | | ^ | | |
- | | |vsync_len | | |
- | | v | | |
- +----------+-------------------------------------+----------+-------+
-
-Note: In addition to being used as subnode(s) of display-timings, the timing
- subnode may also be used on its own. This is appropriate if only one mode
- need be conveyed. In this case, the node should be named 'panel-timing'.
-
-
-Example:
-
- display-timings {
- native-mode = <&timing0>;
- timing0: 1080p24 {
- /* 1920x1080p24 */
- clock-frequency = <52000000>;
- hactive = <1920>;
- vactive = <1080>;
- hfront-porch = <25>;
- hback-porch = <25>;
- hsync-len = <25>;
- vback-porch = <2>;
- vfront-porch = <2>;
- vsync-len = <2>;
- hsync-active = <1>;
- };
- };
-
-Every required property also supports the use of ranges, so the commonly used
-datasheet description with minimum, typical and maximum values can be used.
-
-Example:
-
- timing1: timing {
- /* 1920x1080p24 */
- clock-frequency = <148500000>;
- hactive = <1920>;
- vactive = <1080>;
- hsync-len = <0 44 60>;
- hfront-porch = <80 88 95>;
- hback-porch = <100 148 160>;
- vfront-porch = <0 4 6>;
- vback-porch = <0 36 50>;
- vsync-len = <0 5 6>;
- };

-Ilitek ILI9322 TFT panel driver with SPI control bus
-
-This is a driver for 320x240 TFT panels, accepting a variety of input
-streams that get adapted and scaled to the panel. The panel output has
-960 TFT source driver pins and 240 TFT gate driver pins, VCOM, VCOML and
-VCOMH outputs.
-
-Required properties:
- - compatible: "dlink,dir-685-panel", "ilitek,ili9322"
- (full system-specific compatible is always required to look up configuration)
- - reg: address of the panel on the SPI bus
-
-Optional properties:
- - vcc-supply: core voltage supply, see regulator/regulator.txt
- - iovcc-supply: voltage supply for the interface input/output signals,
- see regulator/regulator.txt
- - vci-supply: voltage supply for analog parts, see regulator/regulator.txt
- - reset-gpios: a GPIO spec for the reset pin, see gpio/gpio.txt
-
- The following optional properties only apply to RGB and YUV input modes and
- can be omitted for BT.656 input modes:
-
- - pixelclk-active: see display/panel/display-timing.txt
- - de-active: see display/panel/display-timing.txt
- - hsync-active: see display/panel/display-timing.txt
- - vsync-active: see display/panel/display-timing.txt
-
-The panel must obey the rules for a SPI slave device as specified in
-spi/spi-bus.txt
-
-The device node can contain one 'port' child node with one child
-'endpoint' node, according to the bindings defined in
-media/video-interfaces.txt. This node should describe panel's video bus.
-
-Example:
-
-panel: display@0 {

+description: |
+ This binding file is a collection of the simple (dumb) panels that
+ requires only a single power-supply.
+ There are optionally a backlight and an enable GPIO.
+ The panel may use an OF graph binding for the association to the display,
+ or it may be a direct child node of the display.
+
+ If the panel is more advanced a dedicated binding file is required.

-For all connections between components up to the TCONs in the display
-pipeline, when there are multiple components of the same type at the
-same depth, the local endpoint ID must be the same as the remote
-component's index. For example, if the remote endpoint is Frontend 1,
-then the local endpoint ID must be 1.
-
- Frontend 0 [0] ------- [0] Backend 0 [0] ------- [0] TCON 0
- [1] -- -- [1] [1] -- -- [1]
- \ / \ /
- X X
- / \ / \
- [0] -- -- [0] [0] -- -- [0]
- Frontend 1 [1] ------- [1] Backend 1 [1] ------- [1] TCON 1
-
-For a two pipeline system such as the one depicted above, the lines
-represent the connections between the components, while the numbers
-within the square brackets corresponds to the ID of the local endpoint.
-
-The same rule also applies to DE 2.0 mixer-TCON connections:
-
- Mixer 0 [0] ----------- [0] TCON 0
- [1] ---- ---- [1]
- \ /
- X
- / \
- [0] ---- ---- [0]
- Mixer 1 [1] ----------- [1] TCON 1

-
-- ports: A ports node with endpoint definitions as defined in
- Documentation/devicetree/bindings/media/video-interfaces.txt. The

-
- The output may have multiple endpoints. TCON can have 1 or 2 channels,
- usually with the first channel being used for the panels interfaces
- (RGB, LVDS, etc.), and the second being used for the outputs that
- require another controller (TV Encoder, HDMI, etc.). The endpoints
- will take an extra property, allwinner,tcon-channel, to specify the
- channel the endpoint is associated to. If that property is not
- present, the endpoint number will be used as the channel number.
-
-For TCONs with channel 0, there is one more clock required:
- - 'tcon-ch0': The clock driving the TCON channel 0
-For TCONs with channel 1, there is one more clock required:
- - 'tcon-ch1': The clock driving the TCON channel 1
-
-When TCON support LVDS (all TCONs except TV TCONs on A83T, R40 and those found
-in A13, H3, H5 and V3s SoCs), you need one more reset line:
- - 'lvds': The reset line driving the LVDS logic
-
-And on the A23, A31, A31s and A33, you need one more clock line:
- - 'lvds-alt': An alternative clock source, separate from the TCON channel 0
- clock, that can be used to drive the LVDS clock
-

+ Blended Video and
+ Mixed Audio to PL
+
+ The Buffer Manager interacts with external interface such as DMA engines or
+ live audio/video streams from the programmable logic. The Video Rendering
+ Pipeline blends the video and graphics layers and performs colorspace
+ conversion. The Audio Mixer mixes the incoming audio streams. The DisplayPort
+ Source Controller handles the DisplayPort protocol and connects to external
+ PHYs.
+
+ The subsystem supports 2 video and 2 audio streams, and various pixel formats
+ and depths up to 4K@30 resolution.
+
+ Please refer to "Zynq UltraScale+ Device Technical Reference Manual"
+ (https://www.xilinx.com/support/documentation/user_guides/ug1085-zynq-ultrascale-trm.pdf)

-* Renesas R-Car (RZ/G) DMA Controller Device Tree bindings
-
-Renesas R-Car (Gen 2/3) and RZ/G SoCs have multiple multi-channel DMA
-controller instances named DMAC capable of serving multiple clients. Channels
-can be dedicated to specific clients or shared between a large number of
-clients.
-
-Each DMA client is connected to one dedicated port of the DMAC, identified by
-an 8-bit port number called the MID/RID. A DMA controller can thus serve up to
-256 clients in total. When the number of hardware channels is lower than the
-number of clients to be served, channels must be shared between multiple DMA
-clients. The association of DMA clients to DMAC channels is fully dynamic and
-not described in these device tree bindings.
-
-Required Properties:
-
-- compatible: "renesas,dmac-<soctype>", "renesas,rcar-dmac" as fallback.
- Examples with soctypes are:
- - "renesas,dmac-r8a7743" (RZ/G1M)

-- reg: base address and length of the registers block for the DMAC
-
-- interrupts: interrupt specifiers for the DMAC, one for each entry in

-- clock-names: "fck" for the functional clock
-- clocks: a list of phandle + clock-specifier pairs, one for each entry
- in clock-names.

+description: |
+ The UDMA-P is intended to perform similar (but significantly upgraded)
+ functions as the packet-oriented DMA used on previous SoC devices. The UDMA-P
+ module supports the transmission and reception of various packet types.
+ The UDMA-P architecture facilitates the segmentation and reassembly of SoC DMA
+ data structure compliant packets to/from smaller data blocks that are natively
+ compatible with the specific requirements of each connected peripheral.
+ Multiple Tx and Rx channels are provided within the DMA which allow multiple
+ segmentation or reassembly operations to be ongoing. The DMA controller
+ maintains state information for each of the channels which allows packet
+ segmentation and reassembly operations to be time division multiplexed between
+ channels in order to share the underlying DMA hardware. An external DMA
+ scheduler is used to control the ordering and rate at which this multiplexing
+ occurs for Transmit operations. The ordering and rate of Receive operations
+ is indirectly controlled by the order in which blocks are pushed into the DMA
+ on the Rx PSI-L interface.
+
+ The UDMA-P also supports acting as both a UTC and UDMA-C for its internal
+ channels. Channels in the UDMA-P can be configured to be either Packet-Based
+ or Third-Party channels on a channel by channel basis.
+
+ All transfers within NAVSS is done between PSI-L source and destination
+ threads.
+ The peripherals serviced by UDMA can be PSI-L native (sa2ul, cpsw, etc) or
+ legacy, non PSI-L native peripherals. In the later case a special, small PDMA
+ is tasked to act as a bridge between the PSI-L fabric and the legacy
+ peripheral.
+
+ PDMAs can be configured via UDMAP peer registers to match with the
+ configuration of the legacy peripheral.

-Required properties:
-
- - compatible: Must be a "<manufacturer>,<model>" pair. The following <model>
- values are supported (assuming "atmel" as manufacturer):
-
- "atmel,24c00",
- "atmel,24c01",
- "atmel,24cs01",
- "atmel,24c02",
- "atmel,24cs02",

- "atmel,24c256",
- "atmel,24c512",
- "atmel,24c1024",
- "atmel,24c2048",
-
- If <manufacturer> is not "atmel", then a fallback must be used
- with the same <model> and "atmel" as manufacturer.
-
- Example:
- compatible = "microchip,24c128", "atmel,24c128";
-
- Supported manufacturers are:
-
- "catalyst",
- "microchip",
- "nxp",
- "ramtron",
- "renesas",
- "rohm",
- "st",
-
- Some vendors use different model names for chips which are just
- variants of the above. Known such exceptions are listed below:
-
- "nxp,se97b" - the fallback is "atmel,24c02",
- "renesas,r1ex24002" - the fallback is "atmel,24c02"
- "renesas,r1ex24016" - the fallback is "atmel,24c16"
- "renesas,r1ex24128" - the fallback is "atmel,24c128"
- "rohm,br24t01" - the fallback is "atmel,24c01"
-
- - reg: The I2C address of the EEPROM.
-
-Optional properties:
-
- - pagesize: The length of the pagesize for writing. Please consult the
- manual of your device, that value varies a lot. A wrong value
- may result in data loss! If not specified, a safety value of
- '1' is used which will be very slow.
-
- - read-only: This parameterless property disables writes to the eeprom.
-
- - size: Total eeprom size in bytes.
-
- - no-read-rollover: This parameterless property indicates that the
- multi-address eeprom does not automatically roll over
- reads to the next slave address. Please consult the
- manual of your device.
-
- - wp-gpios: GPIO to which the write-protect pin of the chip is connected.
-
- - address-width: number of address bits (one of 8, 16).

-UniPhier GPIO controller
-
-Required properties:
-- compatible: Should be "socionext,uniphier-gpio".
-- reg: Specifies offset and length of the register set for the device.
-- gpio-controller: Marks the device node as a GPIO controller.
-- #gpio-cells: Should be 2. The first cell is the pin number and the second
- cell is used to specify optional parameters.
-- interrupt-controller: Marks the device node as an interrupt controller.
-- #interrupt-cells: Should be 2. The first cell defines the interrupt number.
- The second cell bits[3:0] is used to specify trigger type as follows:
- 1 = low-to-high edge triggered
- 2 = high-to-low edge triggered
- 4 = active high level-sensitive
- 8 = active low level-sensitive
- Valid combinations are 1, 2, 3, 4, 8.
-- ngpios: Specifies the number of GPIO lines.
-- gpio-ranges: Mapping to pin controller pins (as described in gpio.txt)
-- socionext,interrupt-ranges: Specifies an interrupt number mapping between
- this GPIO controller and its interrupt parent, in the form of arbitrary
- number of <child-interrupt-base parent-interrupt-base length> triplets.
-
-Optional properties:
-- gpio-ranges-group-names: Used for named gpio ranges (as described in gpio.txt)
-
-Example:
- gpio: gpio@55000000 {
- compatible = "socionext,uniphier-gpio";

- interrupt-parent = <&aidet>;

- ngpios = <248>;
- socionext,interrupt-ranges = <0 48 16>, <16 154 5>, <21 217 3>;

-Consumer Example:
-
- sdhci0_pwrseq {
- compatible = "mmc-pwrseq-emmc";
- reset-gpios = <&gpio UNIPHIER_GPIO_PORT(29, 4) GPIO_ACTIVE_LOW>;
- };
-
-Please note UNIPHIER_GPIO_PORT(29, 4) represents PORT294 in the SoC document.
-Unfortunately, only the one's place is octal in the port numbering. (That is,
-PORT 8, 9, 18, 19, 28, 29, ... are missing.) UNIPHIER_GPIO_PORT() is a helper
-macro to calculate 29 * 8 + 4.

-* Freescale VF610 PORT/GPIO module
-
-The Freescale PORT/GPIO modules are two adjacent modules providing GPIO

-each, and each PORT module has its own interrupt.
-
-Required properties for GPIO node:
-- compatible : Should be "fsl,<soc>-gpio", below is supported list:
- "fsl,vf610-gpio"
- "fsl,imx7ulp-gpio"
-- reg : The first reg tuple represents the PORT module, the second tuple
- the GPIO module.
-- interrupts : Should be the port interrupt shared by all 32 pins.
-- gpio-controller : Marks the device node as a gpio controller.
-- #gpio-cells : Should be two. The first cell is the pin number and
- the second cell is used to specify the gpio polarity:
- 0 = active high
- 1 = active low
-- interrupt-controller: Marks the device node as an interrupt controller.
-- #interrupt-cells : Should be 2. The first cell is the GPIO number.
- The second cell bits[3:0] is used to specify trigger type and level flags:
- 1 = low-to-high edge triggered.
- 2 = high-to-low edge triggered.
- 4 = active high level-sensitive.
- 8 = active low level-sensitive.
-
-Optional properties:
--clocks: Must contain an entry for each entry in clock-names.
- See common clock-bindings.txt for details.
--clock-names: A list of clock names. For imx7ulp, it must contain
- "gpio", "port".
-
-Note: Each GPIO port should have an alias correctly numbered in "aliases"
-node.

-* Marvell PXA GPIO controller
-
-Required properties:
-- compatible : Should be "intel,pxa25x-gpio", "intel,pxa26x-gpio",
- "intel,pxa27x-gpio", "intel,pxa3xx-gpio",
- "marvell,pxa93x-gpio", "marvell,mmp-gpio",
- "marvell,mmp2-gpio" or marvell,pxa1928-gpio.
-- reg : Address and length of the register set for the device
-- interrupts : Should be the port interrupt shared by all gpio pins.
- There're three gpio interrupts in arch-pxa, and they're gpio0,
- gpio1 and gpio_mux. There're only one gpio interrupt in arch-mmp,
- gpio_mux.
-- interrupt-names : Should be the names of irq resources. Each interrupt
- uses its own interrupt name, so there should be as many interrupt names
- as referenced interrupts.
-- interrupt-controller : Identifies the node as an interrupt controller.
-- #interrupt-cells: Specifies the number of cells needed to encode an
- interrupt source.
-- gpio-controller : Marks the device node as a gpio controller.
-- #gpio-cells : Should be two. The first cell is the pin number and
- the second cell is used to specify flags. See gpio.txt for possible
- values.

-Example for a MMP platform:
-
- gpio: gpio@d4019000 {

-* Synopsys DesignWare APB GPIO controller
-
-Required properties:
-- compatible : Should contain "snps,dw-apb-gpio"
-- reg : Address and length of the register set for the device.
-- #address-cells : should be 1 (for addressing port subnodes).
-- #size-cells : should be 0 (port subnodes).
-
-The GPIO controller has a configurable number of ports, each of which are
-represented as child nodes with the following properties:
-
-Required properties:
-- compatible : "snps,dw-apb-gpio-port"
-- gpio-controller : Marks the device node as a gpio controller.
-- #gpio-cells : Should be two. The first cell is the pin number and
- the second cell is used to specify the gpio polarity:
- 0 = active high
- 1 = active low
-- reg : The integer port index of the port, a single cell.
-
-Optional properties:
-- interrupt-controller : The first port may be configured to be an interrupt
-controller.
-- #interrupt-cells : Specifies the number of cells needed to encode an
- interrupt. Shall be set to 2. The first cell defines the interrupt number,
- the second encodes the triger flags encoded as described in
- Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
-- interrupts : The interrupts to the parent controller raised when GPIOs
- generate the interrupts. If the controller provides one combined interrupt
- for all GPIOs, specify a single interrupt. If the controller provides one
- interrupt for each GPIO, provide a list of interrupts that correspond to each
- of the GPIO pins. When specifying multiple interrupts, if any are unconnected,
- use the interrupts-extended property to specify the interrupts and set the
- interrupt controller handle for unused interrupts to 0.
-- snps,nr-gpios : The number of pins in the port, a single cell.
-- resets : Reset line for the controller.

+ Baikal-T1 SoC provides an embedded process, voltage and temperature
+ sensor to monitor an internal SoC environment (chip temperature, supply
+ voltage and process monitor) and on time detect critical situations,
+ which may cause the system instability and even damages. The IP-block

+ control wrapper, which provides a MMIO registers-based access to the
+ sensor core functionality (APB3-bus based) and exposes an additional
+ functions like thresholds/data ready interrupts, its status and masks,
+ measurements timeout. Its internal structure is depicted on the next
+ diagram:

- - reg : Offset and length of the register set for the device
- - interrupts : <IRQ> where IRQ is the interrupt number.
- - clocks : phandles for the clocks, see the description of clock-names below.
- The phandle for the "ic_clk" clock is required. The phandle for the "pclk"
- clock is optional. If a single clock is specified but no clock-name, it is
- the "ic_clk" clock. If both clocks are listed, the "ic_clk" must be first.
-
-Recommended properties :
-
- - clock-frequency : desired I2C bus clock frequency in Hz.
-
-Optional properties :
-
- - clock-names : Contains the names of the clocks:
- "ic_clk", for the core clock used to generate the external I2C clock.
- "pclk", the interface clock, required for register access.
-
- - reg : for "mscc,ocelot-i2c", a second register set to configure the SDA hold
- time, named ICPU_CFG:TWI_DELAY in the datasheet.
-
- - i2c-sda-hold-time-ns : should contain the SDA hold time in nanoseconds.
- This option is only supported in hardware blocks version 1.11a or newer and
- on Microsemi SoCs ("mscc,ocelot-i2c" compatible).
-
- - i2c-scl-falling-time-ns : should contain the SCL falling time in nanoseconds.
- This value which is by default 300ns is used to compute the tLOW period.
-
- - i2c-sda-falling-time-ns : should contain the SDA falling time in nanoseconds.

-* Rockchip RK3xxx I2C controller
-
-This driver interfaces with the native I2C controller present in Rockchip
-RK3xxx SoCs.
-
-Required properties :
-
- - reg : Offset and length of the register set for the device
- - compatible: should be one of the following:
- - "rockchip,rv1108-i2c": for rv1108
- - "rockchip,rk3066-i2c": for rk3066
- - "rockchip,rk3188-i2c": for rk3188

- - "rockchip,rk3288-i2c": for rk3288
- - "rockchip,rk3328-i2c", "rockchip,rk3399-i2c": for rk3328
- - "rockchip,rk3399-i2c": for rk3399
- - interrupts : interrupt number
- - clocks: See ../clock/clock-bindings.txt
- - For older hardware (rk3066, rk3188, rk3228, rk3288):
- - There is one clock that's used both to derive the functional clock
- for the device and as the bus clock.
- - For newer hardware (rk3399): specified by name
- - "i2c": This is used to derive the functional clock.
- - "pclk": This is the bus clock.
-
-Required on RK3066, RK3188 :
-
- - rockchip,grf : the phandle of the syscon node for the general register
- file (GRF)
- - on those SoCs an alias with the correct I2C bus ID (bit offset in the GRF)
- is also required.
-
-Optional properties :
-
- - clock-frequency : SCL frequency to use (in Hz). If omitted, 100kHz is used.
- - i2c-scl-rising-time-ns : Number of nanoseconds the SCL signal takes to rise
- (t(r) in I2C specification). If not specified this is assumed to be
- the maximum the specification allows(1000 ns for Standard-mode,
- 300 ns for Fast-mode) which might cause slightly slower communication.
- - i2c-scl-falling-time-ns : Number of nanoseconds the SCL signal takes to fall
- (t(f) in the I2C specification). If not specified this is assumed to
- be the maximum the specification allows (300 ns) which might cause
- slightly slower communication.
- - i2c-sda-falling-time-ns : Number of nanoseconds the SDA signal takes to fall
- (t(f) in the I2C specification). If not specified we'll use the SCL
- value since they are the same in nearly all cases.
-
-Example:
-
-aliases {
- i2c0 = &i2c0;
-}
-
-i2c0: i2c@2002d000 {

-STMicroelectronics STM32 ADC device driver
-
-STM32 ADC is a successive approximation analog-to-digital converter.
-It has several multiplexed input channels. Conversions can be performed
-in single, continuous, scan or discontinuous mode. Result of the ADC is
-stored in a left-aligned or right-aligned 32-bit data register.
-Conversions can be launched in software or using hardware triggers.
-
-The analog watchdog feature allows the application to detect if the input
-voltage goes beyond the user-defined, higher or lower thresholds.
-
-Each STM32 ADC block can have up to 3 ADC instances.
-
-Each instance supports two contexts to manage conversions, each one has its
-own configurable sequence and trigger:
-- regular conversion can be done in sequence, running in background
-- injected conversions have higher priority, and so have the ability to
- interrupt regular conversion sequence (either triggered in SW or HW).
- Regular sequence is resumed, in case it has been interrupted.
-
-Contents of a stm32 adc root node:
------------------------------------
-Required properties:
-- compatible: Should be one of:
- "st,stm32f4-adc-core"
- "st,stm32h7-adc-core"
- "st,stm32mp1-adc-core"
-- reg: Offset and length of the ADC block register set.
-- interrupts: One or more interrupts for ADC block. Some parts like stm32f4
- and stm32h7 share a common ADC interrupt line. stm32mp1 has two separate
- interrupt lines, one for each ADC within ADC block.
-- clocks: Core can use up to two clocks, depending on part used:
- - "adc" clock: for the analog circuitry, common to all ADCs.
- It's required on stm32f4.
- It's optional on stm32h7.
- - "bus" clock: for registers access, common to all ADCs.
- It's not present on stm32f4.
- It's required on stm32h7.
-- clock-names: Must be "adc" and/or "bus" depending on part used.
-- interrupt-controller: Identifies the controller node as interrupt-parent
-- vdda-supply: Phandle to the vdda input analog voltage.
-- vref-supply: Phandle to the vref input analog reference voltage.
-- #interrupt-cells = <1>;
-- #address-cells = <1>;
-- #size-cells = <0>;
-
-Optional properties:
-- A pinctrl state named "default" for each ADC channel may be defined to set
- inX ADC pins in mode of operation for analog input on external pin.
-- booster-supply: Phandle to the embedded booster regulator that can be used
- to supply ADC analog input switches on stm32h7 and stm32mp1.
-- vdd-supply: Phandle to the vdd input voltage. It can be used to supply ADC
- analog input switches on stm32mp1.
-- st,syscfg: Phandle to system configuration controller. It can be used to
- control the analog circuitry on stm32mp1.
-
-Contents of a stm32 adc child node:
------------------------------------
-An ADC block node should contain at least one subnode, representing an
-ADC instance available on the machine.
-
-Required properties:
-- compatible: Should be one of:
- "st,stm32f4-adc"
- "st,stm32h7-adc"
- "st,stm32mp1-adc"
-- reg: Offset of ADC instance in ADC block (e.g. may be 0x0, 0x100, 0x200).
-- clocks: Input clock private to this ADC instance. It's required only on
- stm32f4, that has per instance clock input for registers access.
-- interrupts: IRQ Line for the ADC (e.g. may be 0 for adc@0, 1 for adc@100 or
- 2 for adc@200).
-- st,adc-channels: List of single-ended channels muxed for this ADC.
- It can have up to 16 channels on stm32f4 or 20 channels on stm32h7, numbered
- from 0 to 15 or 19 (resp. for in0..in15 or in0..in19).
-- st,adc-diff-channels: List of differential channels muxed for this ADC.
- Depending on part used, some channels can be configured as differential
- instead of single-ended (e.g. stm32h7). List here positive and negative
- inputs pairs as <vinp vinn>, <vinp vinn>,... vinp and vinn are numbered
- from 0 to 19 on stm32h7)
- Note: At least one of "st,adc-channels" or "st,adc-diff-channels" is required.
- Both properties can be used together. Some channels can be used as
- single-ended and some other ones as differential (mixed). But channels
- can't be configured both as single-ended and differential (invalid).
-- #io-channel-cells = <1>: See the IIO bindings section "IIO consumers" in
- Documentation/devicetree/bindings/iio/iio-bindings.txt
-
-Optional properties:
-- dmas: Phandle to dma channel for this ADC instance.
- See ../../dma/dma.txt for details.
-- dma-names: Must be "rx" when dmas property is being used.
-- assigned-resolution-bits: Resolution (bits) to use for conversions. Must
- match device available resolutions:
- * can be 6, 8, 10 or 12 on stm32f4
- * can be 8, 10, 12, 14 or 16 on stm32h7
- Default is maximum resolution if unset.
-- st,min-sample-time-nsecs: Minimum sampling time in nanoseconds.
- Depending on hardware (board) e.g. high/low analog input source impedance,
- fine tune of ADC sampling time may be recommended.
- This can be either one value or an array that matches 'st,adc-channels' list,
- to set sample time resp. for all channels, or independently for each channel.
-
-Example:
- adc: adc@40012000 {
- compatible = "st,stm32f4-adc-core";
- reg = <0x40012000 0x400>;
- interrupts = <18>;
- clocks = <&rcc 0 168>;
- clock-names = "adc";
- vref-supply = <®_vref>;
- interrupt-controller;
- pinctrl-names = "default";
- pinctrl-0 = <&adc3_in8_pin>;
-
- #interrupt-cells = <1>;

+description: |
+ STM32 ADC is a successive approximation analog-to-digital converter.
+ It has several multiplexed input channels. Conversions can be performed
+ in single, continuous, scan or discontinuous mode. Result of the ADC is
+ stored in a left-aligned or right-aligned 32-bit data register.
+ Conversions can be launched in software or using hardware triggers.
+
+ The analog watchdog feature allows the application to detect if the input
+ voltage goes beyond the user-defined, higher or lower thresholds.
+
+ Each STM32 ADC block can have up to 3 ADC instances.

-STMicroelectronics STM32 DFSDM ADC device driver
-
-
-STM32 DFSDM ADC is a sigma delta analog-to-digital converter dedicated to
-interface external sigma delta modulators to STM32 micro controllers.
-It is mainly targeted for:
-- Sigma delta modulators (motor control, metering...)
-- PDM microphones (audio digital microphone)
-
-It features up to 8 serial digital interfaces (SPI or Manchester) and
-up to 4 filters on stm32h7 or 6 filters on stm32mp1.
-
-Each child node match with a filter instance.
-
-Contents of a STM32 DFSDM root node:

- "st,stm32mp1-dfsdm"
-- reg: Offset and length of the DFSDM block register set.
-- clocks: IP and serial interfaces clocking. Should be set according
- to rcc clock ID and "clock-names".
-- clock-names: Input clock name "dfsdm" must be defined,
- "audio" is optional. If defined CLKOUT is based on the audio
- clock, else "dfsdm" is used.

-Freescale vf610 Analog to Digital Converter bindings
-
-The devicetree bindings are for the new ADC driver written for
-vf610/i.MX6slx and upward SoCs from Freescale.
-
-Required properties:
-- compatible: Should contain "fsl,vf610-adc"
-- reg: Offset and length of the register set for the device
-- interrupts: Should contain the interrupt for the device
-- clocks: The clock is needed by the ADC controller, ADC clock source is ipg clock.
-- clock-names: Must contain "adc", matching entry in the clocks property.
-- vref-supply: The regulator supply ADC reference voltage.
-
-Recommended properties:
-- fsl,adck-max-frequency: Maximum frequencies according to datasheets operating
- requirements. Three values are required, depending on conversion mode:
- - Frequency in normal mode (ADLPC=0, ADHSC=0)
- - Frequency in high-speed mode (ADLPC=0, ADHSC=1)
- - Frequency in low-power mode (ADLPC=1, ADHSC=0)
-- min-sample-time: Minimum sampling time in nanoseconds. This value has
- to be chosen according to the conversion mode and the connected analog
- source resistance (R_as) and capacitance (C_as). Refer the datasheet's
- operating requirements. A safe default across a wide range of R_as and
- C_as as well as conversion modes is 1000ns.
-
-Example:
-adc0: adc@4003b000 {

+ For proximity sensors whether an object can be considered near to the
+ device depends on parameters like sensor position, covering glass and
+ aperture. This value gives an indication to userspace for which
+ sensor readings this is the case.
+
+ Raw proximity values equal or above this level should be
+ considered 'near' to the device (an object is near to the

-
-The STM32 DAC is a 12-bit voltage output digital-to-analog converter. The DAC
-may be configured in 8 or 12-bit mode. It has two output channels, each with

-
-Contents of a stm32 dac root node:
------------------------------------
-Required properties:
-- compatible: Should be one of:
- "st,stm32f4-dac-core"
- "st,stm32h7-dac-core"
-- reg: Offset and length of the device's register set.
-- clocks: Must contain an entry for pclk (which feeds the peripheral bus
- interface)
-- clock-names: Must be "pclk".
-- vref-supply: Phandle to the vref+ input analog reference supply.
-- #address-cells = <1>;
-- #size-cells = <0>;
-
-Optional properties:
-- resets: Must contain the phandle to the reset controller.
-- A pinctrl state named "default" for each DAC channel may be defined to set
- DAC_OUTx pin in mode of operation for analog output on external pin.
-
-Contents of a stm32 dac child node:
------------------------------------
-DAC core node should contain at least one subnode, representing a
-DAC instance/channel available on the machine.
-
-Required properties:
-- compatible: Must be "st,stm32-dac".
-- reg: Must be either 1 or 2, to define (single) channel in use
-- #io-channel-cells = <1>: See the IIO bindings section "IIO consumers" in

+
+ If the interrupts are used, application will receive an IIO event
+ whenever configured threshold is crossed.

-ChromeOS EC Keyboard
-
-Google's ChromeOS EC Keyboard is a simple matrix keyboard implemented on
-a separate EC (Embedded Controller) device. It provides a message for reading
-key scans from the EC. These are then converted into keycodes for processing
-by the kernel.
-
-This binding is based on matrix-keymap.txt and extends/modifies it as follows:
-
-Required properties:
-- compatible: "google,cros-ec-keyb"
-
-Optional properties:
-- google,needs-ghost-filter: True to enable a ghost filter for the matrix
-keyboard. This is recommended if the EC does not have its own logic or
-hardware for this.
-
-
-Example:
-
-cros-ec-keyb {
- compatible = "google,cros-ec-keyb";
- keypad,num-rows = <8>;
- keypad,num-columns = <13>;
- google,needs-ghost-filter;

-FocalTech EDT-FT5x06 Polytouch driver
-=====================================
-
-There are 5 variants of the chip for various touch panel sizes
-FT5206GE1 2.8" .. 3.8"
-FT5306DE4 4.3" .. 7"
-FT5406EE8 7" .. 8.9"
-FT5506EEG 7" .. 8.9"
-FT5726NEI 5.7” .. 11.6"
-
-The software interface is identical for all those chips, so that
-currently there is no need for the driver to distinguish between the
-different chips. Nevertheless distinct compatible strings are used so
-that a distinction can be added if necessary without changing the DT
-bindings.
-
-
-Required properties:
- - compatible: "edt,edt-ft5206"
- or: "edt,edt-ft5306"
- or: "edt,edt-ft5406"
- or: "edt,edt-ft5506"
- or: "evervision,ev-ft5726"
- or: "focaltech,ft6236"
-
- - reg: I2C slave address of the chip (0x38)
- - interrupts: interrupt specification for the touchdetect
- interrupt
-
-Optional properties:
- - reset-gpios: GPIO specification for the RESET input
- - wake-gpios: GPIO specification for the WAKE input
-
- - pinctrl-names: should be "default"
- - pinctrl-0: a phandle pointing to the pin settings for the
- control gpios
-
- - threshold: allows setting the "click"-threshold in the range
- from 0 to 80.
-
- - gain: allows setting the sensitivity in the range from 0 to
- 31. Note that lower values indicate higher
- sensitivity.
-
- - offset: allows setting the edge compensation in the range from
- 0 to 31.
-
- - offset-x: Same as offset, but applies only to the horizontal position.
- Range from 0 to 80, only supported by evervision,ev-ft5726
- devices.
-
- - offset-y: Same as offset, but applies only to the vertical position.
- Range from 0 to 80, only supported by evervision,ev-ft5726
- devices.
-
- - touchscreen-size-x : See touchscreen.txt
- - touchscreen-size-y : See touchscreen.txt
- - touchscreen-fuzz-x : See touchscreen.txt
- - touchscreen-fuzz-y : See touchscreen.txt
- - touchscreen-inverted-x : See touchscreen.txt
- - touchscreen-inverted-y : See touchscreen.txt
- - touchscreen-swapped-x-y : See touchscreen.txt
-
-Example:
- polytouch: edt-ft5x06@38 {
- compatible = "edt,edt-ft5406", "edt,edt-ft5x06";
- reg = <0x38>;
- pinctrl-names = "default";
- pinctrl-0 = <&edt_ft5x06_pins>;
- interrupt-parent = <&gpio2>;
- interrupts = <5 IRQ_TYPE_EDGE_FALLING>;
- reset-gpios = <&gpio2 6 GPIO_ACTIVE_LOW>;
- wake-gpios = <&gpio4 9 GPIO_ACTIVE_HIGH>;

+
+description: |
+ The i.MX SoC family has multiple buses for which clock frequency (and
+ sometimes voltage) can be adjusted.
+
+ Some of those buses expose register areas mentioned in the memory maps as GPV
+ ("Global Programmers View") but not all. Access to this area might be denied
+ for normal (non-secure) world.
+
+ The buses are based on externally licensed IPs such as ARM NIC-301 and
+ Arteris FlexNOC but DT bindings are specific to the integration of these bus
+ interconnect IPs into imx SOCs.

-Qualcomm SDM845 Network-On-Chip interconnect driver binding
------------------------------------------------------------
-
-SDM845 interconnect providers support system bandwidth requirements through
-RPMh hardware accelerators known as Bus Clock Manager (BCM). The provider is
-able to communicate with the BCM through the Resource State Coordinator (RSC)
-associated with each execution environment. Provider nodes must reside within
-an RPMh device node pertaining to their RSC and each provider maps to a single
-RPMh resource.
-
-Required properties :
-- compatible : shall contain only one of the following:
- "qcom,sdm845-rsc-hlos"
-- #interconnect-cells : should contain 1
-
-Examples:
-
-apps_rsc: rsc {
- rsc_hlos: interconnect {
- compatible = "qcom,sdm845-rsc-hlos";
- #interconnect-cells = <1>;
- };
-};

+- #address-cells: Must be 0.
+- interrupt-controller: Identifies the node as an interrupt controller
+- reg: Specifies the Interrupt Polarity Control Register (INTPCR) in
+ the SCFG.
+- interrupt-map: Specifies the mapping from external interrupts to GIC
+ interrupts.
+- interrupt-map-mask: Must be <0xffffffff 0>.

-* Meta External Trigger Controller Binding
-
-This binding specifies what properties must be available in the device tree
-representation of a Meta external trigger controller.
-
-Required properties:
-
- - compatible: Specifies the compatibility list for the interrupt controller.
- The type shall be <string> and the value shall include "img,meta-intc".
-
- - num-banks: Specifies the number of interrupt banks (each of which can
- handle 32 interrupt sources).
-
- - interrupt-controller: The presence of this property identifies the node
- as an interrupt controller. No property value shall be defined.
-
- - #interrupt-cells: Specifies the number of cells needed to encode an
- interrupt source. The type shall be a <u32> and the value shall be 2.
-
- - #address-cells: Specifies the number of cells needed to encode an
- address. The type shall be <u32> and the value shall be 0. As such,
- 'interrupt-map' nodes do not have to specify a parent unit address.
-
-Optional properties:
-
- - no-mask: The controller doesn't have any mask registers.
-
-* Interrupt Specifier Definition
-
- Interrupt specifiers consists of 2 cells encoded as follows:
-
- - <1st-cell>: The interrupt-number that identifies the interrupt source.
-
- - <2nd-cell>: The Linux interrupt flags containing level-sense information,
- encoded as follows:
- 1 = edge triggered
- 4 = level-sensitive
-
-* Examples
-
-Example 1:
-
- /*
- * Meta external trigger block
- */
- intc: intc {
- // This is an interrupt controller node.
- interrupt-controller;
-
- // No address cells so that 'interrupt-map' nodes which
- // reference this interrupt controller node do not need a parent
- // address specifier.
- #address-cells = <0>;
-
- // Two cells to encode interrupt sources.
- #interrupt-cells = <2>;
-
- // Number of interrupt banks
- num-banks = <2>;
-
- // No HWMASKEXT is available (specify on Chorus2 and Comet ES1)
- no-mask;
-
- // Compatible with Meta hardware trigger block.
- compatible = "img,meta-intc";
- };
-
-Example 2:
-
- /*
- * An interrupt generating device that is wired to a Meta external
- * trigger block.
- */
- uart1: uart@02004c00 {
- // Interrupt source '5' that is level-sensitive.
- // Note that there are only two cells as specified in the
- // interrupt parent's '#interrupt-cells' property.
- interrupts = <5 4 /* level */>;
-
- // The interrupt controller that this device is wired to.
- interrupt-parent = <&intc>;
- };

+3) Interrupt wakeup parent
+--------------------------
+
+Some interrupt controllers in a SoC, are always powered on and have a select
+interrupts routed to them, so that they can wakeup the SoC from suspend. These
+interrupt controllers do not fall into the category of a parent interrupt
+controller and can be specified by the "wakeup-parent" property and contain a
+single phandle referring to the wakeup capable interrupt controller.
+
+ Example:
+ wakeup-parent = <&pdc_intc>;

-MIPS Global Interrupt Controller (GIC)
-
-The MIPS GIC routes external interrupts to individual VPEs and IRQ pins.
-It also supports local (per-processor) interrupts and software-generated
-interrupts which can be used as IPIs. The GIC also includes a free-running
-global timer, per-CPU count/compare timers, and a watchdog.
-
-Required properties:
-- compatible : Should be "mti,gic".
-- interrupt-controller : Identifies the node as an interrupt controller
-- #interrupt-cells : Specifies the number of cells needed to encode an
- interrupt specifier. Should be 3.
- - The first cell is the type of interrupt, local or shared.
- See <include/dt-bindings/interrupt-controller/mips-gic.h>.
- - The second cell is the GIC interrupt number.
- - The third cell encodes the interrupt flags.
- See <include/dt-bindings/interrupt-controller/irq.h> for a list of valid
- flags.
-
-Optional properties:
-- reg : Base address and length of the GIC registers. If not present,
- the base address reported by the hardware GCR_GIC_BASE will be used.
-- mti,reserved-cpu-vectors : Specifies the list of CPU interrupt vectors
- to which the GIC may not route interrupts. Valid values are 2 - 7.
- This property is ignored if the CPU is started in EIC mode.
-- mti,reserved-ipi-vectors : Specifies the range of GIC interrupts that are
- reserved for IPIs.
- It accepts 2 values, the 1st is the starting interrupt and the 2nd is the size
- of the reserved range.
- If not specified, the driver will allocate the last 2 * number of VPEs in the
- system.
-
-Required properties for timer sub-node:
-- compatible : Should be "mti,gic-timer".
-- interrupts : Interrupt for the GIC local timer.
-
-Optional properties for timer sub-node:
-- clocks : GIC timer operating clock.
-- clock-frequency : Clock frequency at which the GIC timers operate.
-
-Note that one of clocks or clock-frequency must be specified.
-
-Example:
-
- gic: interrupt-controller@1bdc0000 {
- compatible = "mti,gic";
- reg = <0x1bdc0000 0x20000>;
-
- interrupt-controller;
- #interrupt-cells = <3>;
-
- mti,reserved-cpu-vectors = <7>;
- mti,reserved-ipi-vectors = <40 8>;
-
- timer {
- compatible = "mti,gic-timer";
- interrupts = <GIC_LOCAL 1 IRQ_TYPE_NONE>;
- clock-frequency = <50000000>;
- };
- };
-
- uart@18101400 {

-* Marvell MMP Interrupt controller
-
-Required properties:
-- compatible : Should be "mrvl,mmp-intc", "mrvl,mmp2-intc" or
- "mrvl,mmp2-mux-intc"
-- reg : Address and length of the register set of the interrupt controller.
- If the interrupt controller is intc, address and length means the range
- of the whole interrupt controller. If the interrupt controller is mux-intc,
- address and length means one register. Since address of mux-intc is in the
- range of intc. mux-intc is secondary interrupt controller.
-- reg-names : Name of the register set of the interrupt controller. It's
- only required in mux-intc interrupt controller.
-- interrupts : Should be the port interrupt shared by mux interrupts. It's
- only required in mux-intc interrupt controller.
-- interrupt-controller : Identifies the node as an interrupt controller.
-- #interrupt-cells : Specifies the number of cells needed to encode an
- interrupt source.
-- mrvl,intc-nr-irqs : Specifies the number of interrupts in the interrupt
- controller.
-- mrvl,clr-mfp-irq : Specifies the interrupt that needs to clear MFP edge
- detection first.
-
-Example:
- intc: interrupt-controller@d4282000 {
- compatible = "mrvl,mmp2-intc";
- interrupt-controller;
- #interrupt-cells = <1>;
- reg = <0xd4282000 0x1000>;

-- interrupt-controller : Declare this node to be an interrupt controller.
-- reg : Interrupt mask address. A list of 4 byte ranges, one per controller.
- One entry in the list represents 32 interrupts.

-SiFive Platform-Level Interrupt Controller (PLIC)
--------------------------------------------------
-
-SiFive SOCs include an implementation of the Platform-Level Interrupt Controller
-(PLIC) high-level specification in the RISC-V Privileged Architecture
-specification. The PLIC connects all external interrupts in the system to all
-hart contexts in the system, via the external interrupt source in each hart.
-
-A hart context is a privilege mode in a hardware execution thread. For example,
-in an 4 core system with 2-way SMT, you have 8 harts and probably at least two
-privilege modes per hart; machine mode and supervisor mode.
-
-Each interrupt can be enabled on per-context basis. Any context can claim
-a pending enabled interrupt and then release it once it has been handled.
-
-Each interrupt has a configurable priority. Higher priority interrupts are
-serviced first. Each context can specify a priority threshold. Interrupts
-with priority below this threshold will not cause the PLIC to raise its
-interrupt line leading to the context.
-
-While the PLIC supports both edge-triggered and level-triggered interrupts,
-interrupt handlers are oblivious to this distinction and therefore it is not
-specified in the PLIC device-tree binding.
-
-While the RISC-V ISA doesn't specify a memory layout for the PLIC, the
-"sifive,plic-1.0.0" device is a concrete implementation of the PLIC that
-contains a specific memory layout, which is documented in chapter 8 of the
-SiFive U5 Coreplex Series Manual <https://static.dev.sifive.com/U54-MC-RVCoreIP.pdf>.
-
-Required properties:
-- compatible : "sifive,plic-1.0.0" and a string identifying the actual
- detailed implementation in case that specific bugs need to be worked around.
-- #address-cells : should be <0> or more.
-- #interrupt-cells : should be <1> or more.
-- interrupt-controller : Identifies the node as an interrupt controller.
-- reg : Should contain 1 register range (address and length).
-- interrupts-extended : Specifies which contexts are connected to the PLIC,
- with "-1" specifying that a context is not present. Each node pointed
- to should be a riscv,cpu-intc node, which has a riscv node as parent.
-- riscv,ndev: Specifies how many external interrupts are supported by
- this controller.
-
-Example:
-
- plic: interrupt-controller@c000000 {
- #address-cells = <0>;
- #interrupt-cells = <1>;
- compatible = "sifive,plic-1.0.0", "sifive,fu540-c000-plic";

- reg = <0xc000000 0x4000000>;

+
+description: |
+ Each PRU-ICSS has a single interrupt controller instance that is common
+ to all the PRU cores. Most interrupt controllers can route 64 input events
+ which are then mapped to 10 possible output interrupts through two levels
+ of mapping. The input events can be triggered by either the PRUs and/or
+ various other PRUSS internal and external peripherals. The first 2 output
+ interrupts (0, 1) are fed exclusively to the internal PRU cores, with the
+ remaining 8 (2 through 9) connected to external interrupt controllers
+ including the MPU and/or other PRUSS instances, DSPs or devices.
+
+ The property "ti,irqs-reserved" is used for denoting the connection
+ differences on the output interrupts 2 through 9. If this property is not
+ defined, it implies that all the PRUSS INTC output interrupts 2 through 9
+ (host_intr0 through host_intr7) are connected exclusively to the Arm interrupt
+ controller.
+
+ The K3 family of SoCs can handle 160 input events that can be mapped to 20
+ different possible output interrupts. The additional output interrupts (10
+ through 19) are connected to new sub-modules within the ICSSG instances.
+
+ This interrupt-controller node should be defined as a child node of the
+ corresponding PRUSS node. The node should be named "interrupt-controller".

-Texas Instruments K3 Interrupt Aggregator
-=========================================
-
-The Interrupt Aggregator (INTA) provides a centralized machine
-which handles the termination of system events to that they can
-be coherently processed by the host(s) in the system. A maximum
-of 64 events can be mapped to a single interrupt.
-
-
- Interrupt Aggregator
- +-----------------------------------------+
- | Intmap VINT |
- | +--------------+ +------------+ |
- m ------>| | vint | bit | | 0 |.....|63| vint0 |
- . | +--------------+ +------------+ | +------+
- . | . . | | HOST |
-Globalevents ------>| . . |------>| IRQ |
- . | . . | | CTRL |
- . | . . | +------+
- n ------>| +--------------+ +------------+ |
- | | vint | bit | | 0 |.....|63| vintx |
- | +--------------+ +------------+ |
- | |
- +-----------------------------------------+
-
-Configuration of these Intmap registers that maps global events to vint is done
-by a system controller (like the Device Memory and Security Controller on K3
-AM654 SoC). Driver should request the system controller to get the range
-of global events and vints assigned to the requesting host. Management
-of these requested resources should be handled by driver and requests
-system controller to map specific global event to vint, bit pair.
-
-Communication between the host processor running an OS and the system
-controller happens through a protocol called TI System Control Interface
-(TISCI protocol). For more details refer:
-Documentation/devicetree/bindings/arm/keystone/ti,sci.txt
-
-TISCI Interrupt Aggregator Node:
--------------------------------
-- compatible: Must be "ti,sci-inta".
-- reg: Should contain registers location and length.
-- interrupt-controller: Identifies the node as an interrupt controller
-- msi-controller: Identifies the node as an MSI controller.
-- interrupt-parent: phandle of irq parent.
-- ti,sci: Phandle to TI-SCI compatible System controller node.
-- ti,sci-dev-id: TISCI device ID of the Interrupt Aggregator.
-- ti,sci-rm-range-vint: Array of TISCI subtype ids representing vints(inta
- outputs) range within this INTA, assigned to the
- requesting host context.
-- ti,sci-rm-range-global-event: Array of TISCI subtype ids representing the
- global events range reaching this IA and are assigned
- to the requesting host context.
-
-Example:
---------

-Texas Instruments K3 Interrupt Router
-=====================================
-
-The Interrupt Router (INTR) module provides a mechanism to mux M
-interrupt inputs to N interrupt outputs, where all M inputs are selectable
-to be driven per N output. An Interrupt Router can either handle edge triggered
-or level triggered interrupts and that is fixed in hardware.
-
- Interrupt Router
- +----------------------+
- | Inputs Outputs |
- +-------+ | +------+ +-----+ |
- | GPIO |----------->| | irq0 | | 0 | | Host IRQ
- +-------+ | +------+ +-----+ | controller
- | . . | +-------+
- +-------+ | . . |----->| IRQ |
- | INTA |----------->| . . | +-------+
- +-------+ | . +-----+ |
- | +------+ | N | |
- | | irqM | +-----+ |
- | +------+ |
- | |
- +----------------------+
-
-There is one register per output (MUXCNTL_N) that controls the selection.
-Configuration of these MUXCNTL_N registers is done by a system controller
-(like the Device Memory and Security Controller on K3 AM654 SoC). System
-controller will keep track of the used and unused registers within the Router.
-Driver should request the system controller to get the range of GIC IRQs
-assigned to the requesting hosts. It is the drivers responsibility to keep
-track of Host IRQs.
-
-Communication between the host processor running an OS and the system
-controller happens through a protocol called TI System Control Interface
-(TISCI protocol). For more details refer:
-Documentation/devicetree/bindings/arm/keystone/ti,sci.txt
-
-TISCI Interrupt Router Node:
-----------------------------
-Required Properties:
-- compatible: Must be "ti,sci-intr".
-- ti,intr-trigger-type: Should be one of the following:
- 1: If intr supports edge triggered interrupts.
- 4: If intr supports level triggered interrupts.
-- interrupt-controller: Identifies the node as an interrupt controller
-- #interrupt-cells: Specifies the number of cells needed to encode an
- interrupt source. The value should be 2.
- First cell should contain the TISCI device ID of source
- Second cell should contain the interrupt source offset
- within the device.
-- ti,sci: Phandle to TI-SCI compatible System controller node.
-- ti,sci-dst-id: TISCI device ID of the destination IRQ controller.
-- ti,sci-rm-range-girq: Array of TISCI subtype ids representing the host irqs
- assigned to this interrupt router. Each subtype id
- corresponds to a range of host irqs.
-
-For more details on TISCI IRQ resource management refer:
-http://downloads.ti.com/tisci/esd/latest/2_tisci_msgs/rm/rm_irq.html
-
-Example:
---------
-The following example demonstrates both interrupt router node and the consumer
-node(main gpio) on the AM654 SoC:
-
-main_intr: interrupt-controller0 {
- compatible = "ti,sci-intr";
- ti,intr-trigger-type = <1>;
- interrupt-controller;
- interrupt-parent = <&gic500>;
- #interrupt-cells = <2>;
- ti,sci = <&dmsc>;
- ti,sci-dst-id = <56>;
- ti,sci-rm-range-girq = <0x1>;
-};
-
-main_gpio0: gpio@600000 {
- ...
- interrupt-parent = <&main_intr>;
- interrupts = <57 256>, <57 257>, <57 258>,
- <57 259>, <57 260>, <57 261>;

-** SMMUv3 required properties:
-
-- compatible : Should include:
-
- * "arm,smmu-v3" for any SMMUv3 compliant
- implementation. This entry should be last in the
- compatible list.
-
-- reg : Base address and size of the SMMU.
-
-- interrupts : Non-secure interrupt list describing the wired
- interrupt sources corresponding to entries in
- interrupt-names. If no wired interrupts are
- present then this property may be omitted.
-
-- interrupt-names : When the interrupts property is present, should
- include the following:
- * "eventq" - Event Queue not empty
- * "priq" - PRI Queue not empty
- * "cmdq-sync" - CMD_SYNC complete
- * "gerror" - Global Error activated
- * "combined" - The combined interrupt is optional,
- and should only be provided if the
- hardware supports just a single,
- combined interrupt line.
- If provided, then the combined interrupt
- will be used in preference to any others.
-
-- #iommu-cells : See the generic IOMMU binding described in
- devicetree/bindings/pci/pci-iommu.txt
- for details. For SMMUv3, must be 1, with each cell
- describing a single stream ID. All possible stream
- IDs which a device may emit must be described.
-
-** SMMUv3 optional properties:
-
-- dma-coherent : Present if DMA operations made by the SMMU (page
- table walks, stream table accesses etc) are cache
- coherent with the CPU.
-
- NOTE: this only applies to the SMMU itself, not
- masters connected upstream of the SMMU.

-* ARM System MMU Architecture Implementation
-
-ARM SoCs may contain an implementation of the ARM System Memory
-Management Unit Architecture, which can be used to provide 1 or 2 stages
-of address translation to bus masters external to the CPU.
-
-The SMMU may also raise interrupts in response to various fault
-conditions.
-
-** System MMU required properties:
-
-- compatible : Should be one of:
-
- "arm,smmu-v1"
- "arm,smmu-v2"
- "arm,mmu-400"
- "arm,mmu-401"
- "arm,mmu-500"
- "cavium,smmu-v2"
- "qcom,smmu-v2"
-
- depending on the particular implementation and/or the
- version of the architecture implemented.
-
- Qcom SoCs must contain, as below, SoC-specific compatibles
- along with "qcom,smmu-v2":
- "qcom,msm8996-smmu-v2", "qcom,smmu-v2",
- "qcom,sdm845-smmu-v2", "qcom,smmu-v2".
-
- Qcom SoCs implementing "arm,mmu-500" must also include,
- as below, SoC-specific compatibles:
- "qcom,sdm845-smmu-500", "arm,mmu-500"
-
-- reg : Base address and size of the SMMU.
-
-- #global-interrupts : The number of global interrupts exposed by the
- device.
-
-- interrupts : Interrupt list, with the first #global-irqs entries
- corresponding to the global interrupts and any
- following entries corresponding to context interrupts,
- specified in order of their indexing by the SMMU.
-
- For SMMUv2 implementations, there must be exactly one
- interrupt per context bank. In the case of a single,
- combined interrupt, it must be listed multiple times.
-
-- #iommu-cells : See Documentation/devicetree/bindings/iommu/iommu.txt
- for details. With a value of 1, each IOMMU specifier
- represents a distinct stream ID emitted by that device
- into the relevant SMMU.
-
- SMMUs with stream matching support and complex masters
- may use a value of 2, where the second cell of the
- IOMMU specifier represents an SMR mask to combine with
- the ID in the first cell. Care must be taken to ensure
- the set of matched IDs does not result in conflicts.
-
-** System MMU optional properties:
-
-- dma-coherent : Present if page table walks made by the SMMU are
- cache coherent with the CPU.
-
- NOTE: this only applies to the SMMU itself, not
- masters connected upstream of the SMMU.
-
-- calxeda,smmu-secure-config-access : Enable proper handling of buggy
- implementations that always use secure access to
- SMMU configuration registers. In this case non-secure
- aliases of secure registers have to be used during
- SMMU configuration.
-
-- stream-match-mask : For SMMUs supporting stream matching and using
- #iommu-cells = <1>, specifies a mask of bits to ignore
- when matching stream IDs (e.g. this may be programmed
- into the SMRn.MASK field of every stream match register
- used). For cases where it is desirable to ignore some
- portion of every Stream ID (e.g. for certain MMU-500
- configurations given globally unique input IDs). This
- property is not valid for SMMUs using stream indexing,
- or using stream matching with #iommu-cells = <2>, and
- may be ignored if present in such cases.
-
-- clock-names: List of the names of clocks input to the device. The
- required list depends on particular implementation and
- is as follows:
- - for "qcom,smmu-v2":
- - "bus": clock required for downstream bus access and
- for the smmu ptw,
- - "iface": clock required to access smmu's registers
- through the TCU's programming interface.
- - unspecified for other implementations.
-
-- clocks: Specifiers for all clocks listed in the clock-names property,
- as per generic clock bindings.
-
-- power-domains: Specifiers for power domains required to be powered on for
- the SMMU to operate, as per generic power domain bindings.
-
-** Deprecated properties:
-
-- mmu-masters (deprecated in favour of the generic "iommus" binding) :
- A list of phandles to device nodes representing bus
- masters for which the SMMU can provide a translation
- and their corresponding Stream IDs. Each device node
- linked from this list must have a "#stream-id-cells"
- property, indicating the number of Stream ID
- arguments associated with its phandle.
-
-** Examples:
-
- /* SMMU with stream matching or stream indexing */

-Samsung Exynos IOMMU H/W, System MMU (System Memory Management Unit)
-
-Samsung's Exynos architecture contains System MMUs that enables scattered
-physical memory chunks visible as a contiguous region to DMA-capable peripheral
-devices like MFC, FIMC, FIMD, GScaler, FIMC-IS and so forth.
-
-System MMU is an IOMMU and supports identical translation table format to
-ARMv7 translation tables with minimum set of page properties including access
-permissions, shareability and security protection. In addition, System MMU has
-another capabilities like L2 TLB or block-fetch buffers to minimize translation
-latency.
-
-System MMUs are in many to one relation with peripheral devices, i.e. single
-peripheral device might have multiple System MMUs (usually one for each bus
-master), but one System MMU can handle transactions from only one peripheral
-device. The relation between a System MMU and the peripheral device needs to be
-defined in device node of the peripheral device.
-
-MFC in all Exynos SoCs and FIMD, M2M Scalers and G2D in Exynos5420 has 2 System
-MMUs.
-* MFC has one System MMU on its left and right bus.
-* FIMD in Exynos5420 has one System MMU for window 0 and 4, the other system MMU
- for window 1, 2 and 3.
-* M2M Scalers and G2D in Exynos5420 has one System MMU on the read channel and
- the other System MMU on the write channel.
-
-For information on assigning System MMU controller to its peripheral devices,
-see generic IOMMU bindings.
-
-Required properties:
-- compatible: Should be "samsung,exynos-sysmmu"
-- reg: A tuple of base address and size of System MMU registers.
-- #iommu-cells: Should be <0>.
-- interrupts: An interrupt specifier for interrupt signal of System MMU,
- according to the format defined by a particular interrupt
- controller.
-- clock-names: Should be "sysmmu" or a pair of "aclk" and "pclk" to gate
- SYSMMU core clocks.
- Optional "master" if the clock to the System MMU is gated by
- another gate clock other core (usually main gate clock
- of peripheral device this SYSMMU belongs to).
-- clocks: Phandles for respective clocks described by clock-names.
-- power-domains: Required if the System MMU is needed to gate its power.
- Please refer to the following document:
- Documentation/devicetree/bindings/power/pd-samsung.txt

+description: |
+ The Kinetic Technologies KTD253 is a white LED backlight that is
+ controlled by a single GPIO line. If you just turn on the backlight
+ it goes to maximum backlight then you can set the level of backlight
+ using pulses on the enable wire. This is sometimes referred to as
+ "expresswire".

-* Common leds properties.
-
-LED and flash LED devices provide the same basic functionality as current
-regulators, but extended with LED and flash LED specific features like
-blinking patterns, flash timeout, flash faults and external flash strobe mode.
-
-Many LED devices expose more than one current output that can be connected
-to one or more discrete LED component. Since the arrangement of connections
-can influence the way of the LED device initialization, the LED components
-have to be tightly coupled with the LED device binding. They are represented
-by child nodes of the parent LED device binding.
-
-
-Optional properties for child nodes:
-- led-sources : List of device current outputs the LED is connected to. The
- outputs are identified by the numbers that must be defined
- in the LED device binding documentation.
-
-- function: LED functon. Use one of the LED_FUNCTION_* prefixed definitions
- from the header include/dt-bindings/leds/common.h.
- If there is no matching LED_FUNCTION available, add a new one.
-
-- color : Color of the LED. Use one of the LED_COLOR_ID_* prefixed definitions
- from the header include/dt-bindings/leds/common.h.
- If there is no matching LED_COLOR_ID available, add a new one.
-
-- function-enumerator: Integer to be used when more than one instance
- of the same function is needed, differing only with
- an ordinal number.
-
-- label : The label for this LED. If omitted, the label is taken from the node
- name (excluding the unit address). It has to uniquely identify
- a device, i.e. no other LED class device can be assigned the same
- label. This property is deprecated - use 'function' and 'color'
- properties instead. function-enumerator has no effect when this
- property is present.
-
-- default-state : The initial state of the LED. Valid values are "on", "off",
- and "keep". If the LED is already on or off and the default-state property is
- set the to same value, then no glitch should be produced where the LED
- momentarily turns off (or on). The "keep" setting will keep the LED at
- whatever its current state is, without producing a glitch. The default is
- off if this property is not present.
-
-- linux,default-trigger : This parameter, if present, is a
- string defining the trigger assigned to the LED. Current triggers are:
- "backlight" - LED will act as a back-light, controlled by the framebuffer
- system
- "default-on" - LED will turn on (but for leds-gpio see "default-state"
- property in Documentation/devicetree/bindings/leds/leds-gpio.txt)
- "heartbeat" - LED "double" flashes at a load average based rate
- "disk-activity" - LED indicates disk activity
- "ide-disk" - LED indicates IDE disk activity (deprecated),
- in new implementations use "disk-activity"
- "timer" - LED flashes at a fixed, configurable rate
- "pattern" - LED alters the brightness for the specified duration with one
- software timer (requires "led-pattern" property)
-
-- led-pattern : Array of integers with default pattern for certain triggers.
- Each trigger may parse this property differently:
- - one-shot : two numbers specifying delay on and delay off (in ms),
- - timer : two numbers specifying delay on and delay off (in ms),
- - pattern : the pattern is given by a series of tuples, of
- brightness and duration (in ms). The exact format is
- described in:
- Documentation/devicetree/bindings/leds/leds-trigger-pattern.txt
-
-
-- led-max-microamp : Maximum LED supply current in microamperes. This property
- can be made mandatory for the board configurations
- introducing a risk of hardware damage in case an excessive
- current is set.
- For flash LED controllers with configurable current this
- property is mandatory for the LEDs in the non-flash modes
- (e.g. torch or indicator).
-
-- panic-indicator : This property specifies that the LED should be used,
- if at all possible, as a panic indicator.
-
-- trigger-sources : List of devices which should be used as a source triggering
- this LED activity. Some LEDs can be related to a specific
- device and should somehow indicate its state. E.g. USB 2.0
- LED may react to device(s) in a USB 2.0 port(s).
- Another common example is switch or router with multiple
- Ethernet ports each of them having its own LED assigned
- (assuming they are not hardwired). In such cases this
- property should contain phandle(s) of related source
- device(s).
- In many cases LED can be related to more than one device
- (e.g. one USB LED vs. multiple USB ports). Each source
- should be represented by a node in the device tree and be
- referenced by a phandle and a set of phandle arguments. A
- length of arguments should be specified by the
- #trigger-source-cells property in the source node.
-

+description:
+ LED and flash LED devices provide the same basic functionality as current
+ regulators, but extended with LED and flash LED specific features like
+ blinking patterns, flash timeout, flash faults and external flash strobe mode.
+
+ Many LED devices expose more than one current output that can be connected
+ to one or more discrete LED component. Since the arrangement of connections
+ can influence the way of the LED device initialization, the LED components
+ have to be tightly coupled with the LED device binding. They are represented
+ by child nodes of the parent LED device binding.
+
+properties:
+ led-sources:
+ description:
+ List of device current outputs the LED is connected to. The outputs are
+ identified by the numbers that must be defined in the LED device binding
+ documentation.
+ $ref: /schemas/types.yaml#definitions/uint32-array
+
+ function:

+ LED function. Use one of the LED_FUNCTION_* prefixed definitions
+ from the header include/dt-bindings/leds/common.h. If there is no
+ matching LED_FUNCTION available, add a new one.
+ $ref: /schemas/types.yaml#definitions/string
+
+ color:
+ description:
+ Color of the LED. Use one of the LED_COLOR_ID_* prefixed definitions from
+ the header include/dt-bindings/leds/common.h. If there is no matching
+ LED_COLOR_ID available, add a new one.

+ Integer to be used when more than one instance of the same function is
+ needed, differing only with an ordinal number.
+ $ref: /schemas/types.yaml#definitions/uint32
+
+ label:
+ description:
+ The label for this LED. If omitted, the label is taken from the node name
+ (excluding the unit address). It has to uniquely identify a device, i.e.
+ no other LED class device can be assigned the same label. This property is
+ deprecated - use 'function' and 'color' properties instead.
+ function-enumerator has no effect when this property is present.
+
+ default-state:
+ description:
+ The initial state of the LED. If the LED is already on or off and the
+ default-state property is set the to same value, then no glitch should be
+ produced where the LED momentarily turns off (or on). The "keep" setting
+ will keep the LED at whatever its current state is, without producing a
+ glitch.
+ $ref: /schemas/types.yaml#definitions/string
+ enum:
+ - on

+ Array of integers with default pattern for certain triggers.
+
+ Each trigger may parse this property differently:
+ - one-shot : two numbers specifying delay on and delay off (in ms),
+ - timer : two numbers specifying delay on and delay off (in ms),
+ - pattern : the pattern is given by a series of tuples, of

+ trigger-sources:

+ indicate its state. E.g. USB 2.0 LED may react to device(s) in a USB 2.0
+ port(s).
+ Another common example is switch or router with multiple Ethernet ports
+ each of them having its own LED assigned (assuming they are not
+ hardwired). In such cases this property should contain phandle(s) of
+ related source device(s).
+ In many cases LED can be related to more than one device (e.g. one USB LED
+ vs. multiple USB ports). Each source should be represented by a node in
+ the device tree and be referenced by a phandle and a set of phandle
+ arguments. A length of arguments should be specified by the
+ #trigger-source-cells property in the source node.

+This LED Board (aka RED LEDs board) is widely used in
+coffee vending machines produced by Crane Merchandising Systems.
+The board manages 3 LEDs and supports predefined blinking patterns
+for specific leds.
+
+Vending area LED encoded with symbol 'V' (hex code 0x56).
+Doesn't have any hardware blinking pattern.
+
+Screen light tube LED which surrounds vending machine screen and
+encoded with symbol 'S' (hex code 0x53). Supports blinking breathing pattern.
+
+Water Pipe LED encoded with symbol 'P' (hex code 0x50) and
+actually consists of 5 LEDs that exposed by protocol like one LED.
+Supports next patterns:
+- cascade pattern
+- inversed cascade pattern
+- bounce pattern
+- inversed bounce pattern
+
+Required properties:
+- compatible : "crane,el15203000"
+- #address-cells : must be 1
+- #size-cells : must be 0

+description: |
+ The ARM's Message-Handling-Unit (MHU) is a mailbox controller that has 3
+ independent channels/links to communicate with remote processor(s). MHU links
+ are hardwired on a platform. A link raises interrupt for any received data.
+ However, there is no specified way of knowing if the sent data has been read
+ by the remote. This driver assumes the sender polls STAT register and the
+ remote clears it after having read the data. The last channel is specified to
+ be a 'Secure' resource, hence can't be used by Linux running NS.
+
+ The MHU hardware also allows operations in doorbell mode. The MHU drives the
+ interrupt signal using a 32-bit register, with all 32-bits logically ORed
+ together. It provides a set of registers to enable software to set, clear and
+ check the status of each of the bits of this register independently. The use
+ of 32 bits per interrupt line enables software to provide more information
+ about the source of the interrupt. For example, each bit of the register can
+ be associated with a type of event that can contribute to raising the
+ interrupt. Each of the 32-bits can be used as "doorbell" to alert the remote
+ processor.

-
-Required properties:
---------------------
-- compatible: Shall be "arm,mhu" & "arm,primecell"
-- reg: Contains the mailbox register address range (base
- address and length)
-- #mbox-cells Shall be 1 - the index of the channel needed.

-NXP i.MX Messaging Unit (MU)
---------------------------------------------------------------------
-
-The Messaging Unit module enables two processors within the SoC to
-communicate and coordinate by passing messages (e.g. data, status
-and control) through the MU interface. The MU also provides the ability
-for one processor to signal the other processor using interrupts.
-
-Because the MU manages the messaging between processors, the MU uses
-different clocks (from each side of the different peripheral buses).
-Therefore, the MU must synchronize the accesses from one side to the
-other. The MU accomplishes synchronization using two sets of matching
-registers (Processor A-facing, Processor B-facing).
-
-Messaging Unit Device Node:
-=============================
-
-Required properties:
--------------------
-- compatible : should be "fsl,<chip>-mu", the supported chips include
- imx6sx, imx7s, imx8qxp, imx8qm.
- The "fsl,imx6sx-mu" compatible is seen as generic and should
- be included together with SoC specific compatible.
-- reg : Should contain the registers location and length
-- interrupts : Interrupt number. The interrupt specifier format depends
- on the interrupt controller parent.
-- #mbox-cells: Must be 2.
- <&phandle type channel>
- phandle : Label name of controller
- type : Channel type
- channel : Channel number
-
- This MU support 4 type of unidirectional channels, each type
- has 4 channels. A total of 16 channels. Following types are
- supported:
- 0 - TX channel with 32bit transmit register and IRQ transmit
- acknowledgment support.
- 1 - RX channel with 32bit receive register and IRQ support
- 2 - TX doorbell channel. Without own register and no ACK support.
- 3 - RX doorbell channel.
-
-Optional properties:
--------------------
-- clocks : phandle to the input clock.
-- fsl,mu-side-b : Should be set for side B MU.
-
-Examples:
---------
-lsio_mu0: mailbox@5d1b0000 {

-* STMicroelectronics STM32 IPCC (Inter-Processor Communication Controller)
-
-The IPCC block provides a non blocking signaling mechanism to post and
-retrieve messages in an atomic way between two processors.
-It provides the signaling for N bidirectionnal channels. The number of channels
-(N) can be read from a dedicated register.
-
-Required properties:
-- compatible: Must be "st,stm32mp1-ipcc"
-- reg: Register address range (base address and length)
-- st,proc-id: Processor id using the mailbox (0 or 1)
-- clocks: Input clock
-- interrupt-names: List of names for the interrupts described by the interrupt
- property. Must contain the following entries:
- - "rx"
- - "tx"
- - "wakeup"
-- interrupts: Interrupt specifiers for "rx channel occupied", "tx channel
- free" and "system wakeup".
-- #mbox-cells: Number of cells required for the mailbox specifier. Must be 1.
- The data contained in the mbox specifier of the "mboxes"
- property in the client node is the mailbox channel index.
-
-Optional properties:
-- wakeup-source: Flag to indicate whether this device can wake up the system
-
-
-
-Example:
- ipcc: mailbox@4c001000 {
- compatible = "st,stm32mp1-ipcc";
- #mbox-cells = <1>;
- reg = <0x4c001000 0x400>;
- st,proc-id = <0>;
- interrupts-extended = <&intc GIC_SPI 100 IRQ_TYPE_NONE>,
- <&intc GIC_SPI 101 IRQ_TYPE_NONE>,
- <&aiec 62 1>;
- interrupt-names = "rx", "tx", "wakeup";
- clocks = <&rcc_clk IPCC>;
- wakeup-source;
- }
-
-Client:
- mbox_test {
- ...
- mboxes = <&ipcc 0>, <&ipcc 1>;
- };

-Amlogic Video Decoder
-================================
-
-The video decoding IP lies within the DOS memory region,
-except for the hardware bitstream parser that makes use of an undocumented
-region.
-
-It makes use of the following blocks:
-
-- ESPARSER is a bitstream parser that outputs to a VIFIFO. Further VDEC blocks
-then feed from this VIFIFO.
-- VDEC_1 can decode MPEG-1, MPEG-2, MPEG-4 part 2, MJPEG, H.263, H.264, VC-1.
-- VDEC_HEVC can decode HEVC and VP9.
-
-Both VDEC_1 and VDEC_HEVC share the "vdec" IRQ and as such cannot run
-concurrently.
-
-Device Tree Bindings:
----------------------
-
-VDEC: Video Decoder
---------------------------
-
-Required properties:
-- compatible: value should be different for each SoC family as :
- - GXBB (S905) : "amlogic,gxbb-vdec"
- - GXL (S905X, S905D) : "amlogic,gxl-vdec"
- - GXM (S912) : "amlogic,gxm-vdec"
- followed by the common "amlogic,gx-vdec"
-- reg: base address and size of he following memory-mapped regions :
- - dos
- - esparser
-- reg-names: should contain the names of the previous memory regions
-- interrupts: should contain the following IRQs:
- - vdec
- - esparser
-- interrupt-names: should contain the names of the previous interrupts
-- amlogic,ao-sysctrl: should point to the AOBUS sysctrl node
-- amlogic,canvas: should point to a canvas provider node
-- clocks: should contain the following clocks :
- - dos_parser
- - dos
- - vdec_1
- - vdec_hevc
-- clock-names: should contain the names of the previous clocks
-- resets: should contain the parser reset
-- reset-names: should be "esparser"
-
-Example:
-
-vdec: video-codec@c8820000 {
- compatible = "amlogic,gxbb-vdec", "amlogic,gx-vdec";
- reg = <0x0 0xc8820000 0x0 0x10000>,

+description: -|
+ The IMI D&D RDACM20 and RDACM21 are GMSL-compatible camera designed for
+ automotive applications.
+
+ The RDACM20 camera module encloses a Maxim Integrated MAX9271 GMSL serializer,
+ coupled with an OV10635 image sensor and an embedded MCU. Both the MCU and
+ the image sensor are connected to the serializer local I2C bus and are
+ accessible by the host SoC by direct addressing.
+
+ The RDACM21 camera module encloses the same serializer, coupled with an
+ OV10640 image sensor and an OV490 ISP. Only the OV490 ISP is interfaced to
+ the serializer local I2C bus while the image sensor is not accessible from
+ the host SoC.
+
+ They both connect to a remote GMSL endpoint through a coaxial cable.

+ +---------------+ +--------------------------------+
+
+ Both camera modules serialize video data generated by the embedded camera
+ sensor on the GMSL serial channel to a remote GMSL de-serializer. They also
+ receive and transmit I2C messages encapsulated and transmitted on the GMSL
+ bidirectional control channel.
+
+ All I2C traffic received on the GMSL link not directed to the serializer is
+ propagated on the local I2C bus to the remote device there connected. All the
+ I2C traffic generated on the local I2C bus not directed to the serializer is
+ propagated to the remote de-serializer encapsulated in the GMSL control
+ channel.
+
+ The RDACM20 and RDACM21 DT node should be a direct child of the GMSL
+ deserializer's I2C bus corresponding to the GMSL link that the camera is
+ attached to.

-Renesas Capture Engine Unit (CEU)
-----------------------------------------------
-
-The Capture Engine Unit is the image capture interface found in the Renesas
-SH Mobile, R-Mobile and RZ SoCs.
-
-The interface supports a single parallel input with data bus width of 8 or 16
-bits.
-
-Required properties:
-- compatible: Shall be one of the following values:
- "renesas,r7s72100-ceu" for CEU units found in RZ/A1H and RZ/A1M SoCs
- "renesas,r8a7740-ceu" for CEU units found in R-Mobile A1 R8A7740 SoCs
-- reg: Registers address base and size.
-- interrupts: The interrupt specifier.
-
-The CEU supports a single parallel input and should contain a single 'port'
-subnode with a single 'endpoint'. Connection to input devices are modeled
-according to the video interfaces OF bindings specified in:
-[1] Documentation/devicetree/bindings/media/video-interfaces.txt
-
-Optional endpoint properties applicable to parallel input bus described in
-the above mentioned "video-interfaces.txt" file are supported.
-
-- hsync-active: See [1] for description. If property is not present,
- default is active high.
-- vsync-active: See [1] for description. If property is not present,
- default is active high.
-- bus-width: See [1] for description. Accepted values are '8' and '16'.
- If property is not present, default is '8'.
-- field-even-active: See [1] for description. If property is not present,
- an even field is identified by a logic 0 (active-low signal).
-
-Example:
-
-The example describes the connection between the Capture Engine Unit and an
-OV7670 image sensor connected to i2c1 interface.

-caching, and conversion of AXI transactions in order to reduce the memory
-bandwidth.
-
-There are three types of FCP: FCP for Codec (FCPC), FCP for VSP (FCPV) and FCP
-for FDP (FCPF). Their configuration and behaviour depend on the module they
-are paired with. These DT bindings currently support the FCPV and FCPF.
-
- - compatible: Must be one or more of the following
-
- - "renesas,fcpv" for generic compatible 'FCP for VSP'
- - "renesas,fcpf" for generic compatible 'FCP for FDP'

- - interrupts: the interrupt for the device
- - clocks: Reference to the parent clock
-
-Additionally, an alias named vinX will need to be created to specify
-which video input device this is.
-
-The per-board settings Gen2 platforms:
-
-- port - sub-node describing a single endpoint connected to the VIN
- from external SoC pins as described in video-interfaces.txt[1].
- Only the first one will be considered as each vin interface has one
- input port.
-
- - Optional properties for endpoint nodes:
- - hsync-active: see [1] for description. Default is active high.
- - vsync-active: see [1] for description. Default is active high.
- If both HSYNC and VSYNC polarities are not specified, embedded
- synchronization is selected.
- - field-active-even: see [1] for description. Default is active high.
- - bus-width: see [1] for description. The selected bus width depends on
- the SoC type and selected input image format.
- Valid values are: 8, 10, 12, 16, 24 and 32.
- - data-shift: see [1] for description. Valid values are 0 and 8.
- - data-enable-active: polarity of CLKENB signal, see [1] for
- description. Default is active high.
-
-The per-board settings Gen3 and RZ/G2 platforms:
-
-Gen3 and RZ/G2 platforms can support both a single connected parallel input
-source from external SoC pins (port@0) and/or multiple parallel input sources
-from local SoC CSI-2 receivers (port@1) depending on SoC.
-
-- renesas,id - ID number of the VIN, VINx in the documentation.
-- ports
- - port@0 - sub-node describing a single endpoint connected to the VIN
- from external SoC pins as described in video-interfaces.txt[1].
- Describing more than one endpoint in port@0 is invalid. Only VIN
- instances that are connected to external pins should have port@0.
-
- Endpoint nodes of port@0 support the optional properties listed in
- the Gen2 per-board settings description.
-
- - port@1 - sub-nodes describing one or more endpoints connected to
- the VIN from local SoC CSI-2 receivers. The endpoint numbers must
- use the following schema.
-
- - endpoint@0 - sub-node describing the endpoint connected to CSI20
- - endpoint@1 - sub-node describing the endpoint connected to CSI21
- - endpoint@2 - sub-node describing the endpoint connected to CSI40
- - endpoint@3 - sub-node describing the endpoint connected to CSI41
-
- Endpoint nodes of port@1 do not support any optional endpoint property.

+
+description:
+ The R-Car Video Input (VIN) device provides video input capabilities for the
+ Renesas R-Car family of devices.
+
+ Each VIN instance has a single parallel input that supports RGB and YUV video,
+ with both external synchronization and BT.656 synchronization for the latter.
+ Depending on the instance the VIN input is connected to external SoC pins, or
+ on Gen3 and RZ/G2 platforms to a CSI-2 receiver.

-Texas Instruments DRA72x CAMERA ADAPTATION LAYER (CAL)
-------------------------------------------------------
-
-The Camera Adaptation Layer (CAL) is a key component for image capture
-applications. The capture module provides the system interface and the
-processing capability to connect CSI2 image-sensor modules to the
-DRA72x device.
-
-Required properties:
-- compatible: must be "ti,dra72-cal"
-- reg: CAL Top level, Receiver Core #0, Receiver Core #1 and Camera RX
- control address space
-- reg-names: cal_top, cal_rx_core0, cal_rx_core1, and camerrx_control
- registers
-- interrupts: should contain IRQ line for the CAL;
-
-CAL supports 2 camera port nodes on MIPI bus. Each CSI2 camera port nodes
-should contain a 'port' child node with child 'endpoint' node. Please
-refer to the bindings defined in
-Documentation/devicetree/bindings/media/video-interfaces.txt.

- lens-focus: A phandle to the node of the focus lens controller.
-- rotation: The device, typically an image sensor, is not mounted upright,
- but a number of degrees counter clockwise. Typical values are 0 and 180
- (upside down).
+- rotation: The camera rotation is expressed as the angular difference in
+ degrees between two reference systems, one relative to the camera module, and
+ one defined on the external world scene to be captured when projected on the
+ image sensor pixel array.
+ A camera sensor has a 2-dimensional reference system 'Rc' defined by
+ its pixel array read-out order. The origin is set to the first pixel
+ being read out, the X-axis points along the column read-out direction
+ towards the last columns, and the Y-axis along the row read-out
+ direction towards the last row.
+
+ A typical example for a sensor with a 2592x1944 pixel array matrix
+ observed from the front is:
+
+ 2591 X-axis 0
+ <------------------------+ 0
+ .......... ... ..........!
+ .......... ... ..........! Y-axis
+ ... !
+ .......... ... ..........!
+ .......... ... ..........! 1943
+ V
+
+ The external world scene reference system 'Rs' is a 2-dimensional
+ reference system on the focal plane of the camera module. The origin is
+ placed on the top-left corner of the visible scene, the X-axis points
+ towards the right, and the Y-axis points towards the bottom of the
+ scene. The top, bottom, left and right directions are intentionally not
+ defined and depend on the environment in which the camera is used.
+
+ A typical example of a (very common) picture of a shark swimming from
+ left to right, as seen from the camera, is:
+
+ 0 X-axis

+ ˙·.¸ !
+ ˙·.¸ !
+ ˙·.¸!
+
+ When projected on the sensor's pixel array, the image and the associated
+ reference system 'Rs' are typically (but not always) inverted, due to
+ the camera module's lens optical inversion effect.
+
+ Assuming the above represented scene of the swimming shark, the lens
+ inversion projects the scene and its reference system onto the sensor
+ pixel array, seen from the front of the camera sensor, as follows:

+
+ Note the shark being upside-down.
+
+ The resulting projected reference system is named 'Rp'.
+
+ The camera rotation property is then defined as the angular difference
+ in the counter-clockwise direction between the camera reference system
+ 'Rc' and the projected scene reference system 'Rp'. It is expressed in

+
+description: |
+ The Xilinx MIPI CSI-2 Receiver Subsystem is used to capture MIPI CSI-2
+ traffic from compliant camera sensors and send the output as AXI4 Stream
+ video data for image processing.
+ The subsystem consists of a MIPI D-PHY in slave mode which captures the
+ data packets. This is passed along the MIPI CSI-2 Rx IP which extracts the
+ packet data. The optional Video Format Bridge (VFB) converts this data to
+ AXI4 Stream video data.
+ For more details, please refer to PG232 Xilinx MIPI CSI-2 Receiver Subsystem.
+ Please note that this bindings includes only the MIPI CSI-2 Rx controller
+ and Video Format Bridge and not D-PHY.

+* Exynos5422 frequency and voltage scaling for Dynamic Memory Controller device
+
+The Samsung Exynos5422 SoC has DMC (Dynamic Memory Controller) to which the DRAM
+memory chips are connected. The driver is to monitor the controller in runtime
+and switch frequency and voltage. To monitor the usage of the controller in
+runtime, the driver uses the PPMU (Platform Performance Monitoring Unit), which
+is able to measure the current load of the memory.
+When 'userspace' governor is used for the driver, an application is able to
+switch the DMC and memory frequency.
+
+Required properties for DMC device for Exynos5422:
+- compatible: Should be "samsung,exynos5422-dmc".
+- clocks : list of clock specifiers, must contain an entry for each
+ required entry in clock-names for CLK_FOUT_SPLL, CLK_MOUT_SCLK_SPLL,
+ CLK_FF_DOUT_SPLL2, CLK_FOUT_BPLL, CLK_MOUT_BPLL, CLK_SCLK_BPLL,
+ CLK_MOUT_MX_MSPLL_CCORE, CLK_MOUT_MX_MSPLL_CCORE_PHY, CLK_MOUT_MCLK_CDREX,
+- clock-names : should include "fout_spll", "mout_sclk_spll", "ff_dout_spll2",
+ "fout_bpll", "mout_bpll", "sclk_bpll", "mout_mx_mspll_ccore",
+ "mout_mclk_cdrex" entries
+- devfreq-events : phandles for PPMU devices connected to this DMC.
+- vdd-supply : phandle for voltage regulator which is connected.
+- reg : registers of two CDREX controllers.
+- operating-points-v2 : phandle for OPPs described in v2 definition.
+- device-handle : phandle of the connected DRAM memory device. For more
+ information please refer to documentation file:
+ Documentation/devicetree/bindings/ddr/lpddr3.txt
+- devfreq-events : phandles of the PPMU events used by the controller.
+- samsung,syscon-clk : phandle of the clock register set used by the controller,
+ these registers are used for enabling a 'pause' feature and are not
+ exposed by clock framework but they must be used in a safe way.
+ The register offsets are in the driver code and specyfic for this SoC
+ type.
+
+Optional properties for DMC device for Exynos5422:
+- interrupt-parent : The parent interrupt controller.
+- interrupts : Contains the IRQ line numbers for the DMC internal performance
+ event counters in DREX0 and DREX1 channels. Align with specification of the
+ interrupt line(s) in the interrupt-parent controller.
+- interrupt-names : IRQ names "drex_0" and "drex_1", the order should be the
+ same as in the 'interrupts' list above.

+
+description:
+ The DDRC block is integrated in i.MX8M for interfacing with DDR based
+ memories.
+
+ It supports switching between different frequencies at runtime but during
+ this process RAM itself becomes briefly inaccessible so actual frequency
+ switching is implemented by TF-A code which runs from a SRAM area.
+
+ The Linux driver for the DDRC doesn't even map registers (they're included
+ for the sake of "describing hardware"), it mostly just exposes firmware
+ capabilities through standard Linux mechanism like devfreq and OPP tables.

-* Ingenic JZ4780 NAND/external memory controller (NEMC)
-
-This file documents the device tree bindings for the NEMC external memory
-controller in Ingenic JZ4780
-
-Required properties:
-- compatible: Should be set to one of:
- "ingenic,jz4740-nemc" (JZ4740)
- "ingenic,jz4780-nemc" (JZ4780)
-- reg: Should specify the NEMC controller registers location and length.
-- clocks: Clock for the NEMC controller.
-- #address-cells: Must be set to 2.
-- #size-cells: Must be set to 1.
-- ranges: A set of ranges for each bank describing the physical memory layout.
- Each should specify the following 4 integer values:
-
- <cs number> 0 <physical address of mapping> <size of mapping>
-
-Each child of the NEMC node describes a device connected to the NEMC.
-
-Required child node properties:
-- reg: Should contain at least one register specifier, given in the following
- format:
-
- <cs number> <offset> <size>
-
- Multiple registers can be specified across multiple banks. This is needed,
- for example, for packaged NAND devices with multiple dies. Such devices
- should be grouped into a single node.
-
-Optional child node properties:
-- ingenic,nemc-bus-width: Specifies the bus width in bits. Defaults to 8 bits.
-- ingenic,nemc-tAS: Address setup time in nanoseconds.
-- ingenic,nemc-tAH: Address hold time in nanoseconds.
-- ingenic,nemc-tBP: Burst pitch time in nanoseconds.
-- ingenic,nemc-tAW: Access wait time in nanoseconds.
-- ingenic,nemc-tSTRV: Static memory recovery time in nanoseconds.
-
-If a child node references multiple banks in its "reg" property, the same value
-for all optional parameters will be configured for all banks. If any optional
-parameters are omitted, they will be left unchanged from whatever they are
-configured to when the NEMC device is probed (which may be the reset value as
-given in the hardware reference manual, or a value configured by the boot
-loader).
-
-Example (NEMC node with a NAND child device attached at CS1):
-

+description: |
+ The NVIDIA Tegra186 SoC features a 128 bit memory controller that is split
+ into four 32 bit channels to support LPDDR4 with x16 subpartitions. The MC
+ handles memory requests for 40-bit virtual addresses from internal clients
+ and arbitrates among them to allocate memory bandwidth.
+
+ Up to 15 GiB of physical memory can be supported. Security features such as
+ encryption of traffic to and from DRAM via general security apertures are
+ available for video and other secure applications, as well as DRAM ECC for
+ automotive safety applications (single bit error correction and double bit
+ error detection).

+description: |
+ Tegra30 Memory Controller architecturally consists of the following parts:
+
+ Arbitration Domains, which can handle a single request or response per
+ clock from a group of clients. Typically, a system has a single Arbitration
+ Domain, but an implementation may divide the client space into multiple
+ Arbitration Domains to increase the effective system bandwidth.
+
+ Protocol Arbiter, which manage a related pool of memory devices. A system
+ may have a single Protocol Arbiter or multiple Protocol Arbiters.
+
+ Memory Crossbar, which routes request and responses between Arbitration
+ Domains and Protocol Arbiters. In the simplest version of the system, the
+ Memory Crossbar is just a pass through between a single Arbitration Domain
+ and a single Protocol Arbiter.
+
+ Global Resources, which include things like configuration registers which
+ are shared across the Memory Subsystem.
+
+ The Tegra30 Memory Controller handles memory requests from internal clients
+ and arbitrates among them to allocate memory bandwidth for DDR3L and LPDDR2
+ SDRAMs.

-DT bindings for Renesas R-Mobile and SH-Mobile memory controllers
-=================================================================
-
-Renesas R-Mobile and SH-Mobile SoCs contain one or more memory controllers.
-These memory controllers differ from one SoC variant to another, and are called
-by different names ("DDR Bus Controller (DBSC)", "DDR3 Bus State Controller
-(DBSC3)", "SDRAM Bus State Controller (SBSC)").
-
-Currently memory controller device nodes are used only to reference PM
-domains, and prevent these PM domains from being powered down, which would
-crash the system.
-
-As there exist no actual drivers for these controllers yet, these bindings
-should be considered EXPERIMENTAL for now.
-
-Required properties:
- - compatible: Must be one of the following SoC-specific values:
- - "renesas,dbsc-r8a73a4" (R-Mobile APE6)
- - "renesas,dbsc3-r8a7740" (R-Mobile A1)
- - "renesas,sbsc-sh73a0" (SH-Mobile AG5)
- - reg: Must contain the base address and length of the memory controller's
- registers.
-
-Optional properties:
- - interrupts: Must contain a list of interrupt specifiers for memory
- controller interrupts, if available.
- - interrupt-names: Must contain a list of interrupt names corresponding to
- the interrupts in the interrupts property, if available.
- Valid interrupt names are:
- - "sec" (secure interrupt)
- - "temp" (normal (temperature) interrupt)
- - power-domains: Must contain a reference to the PM domain that the memory
- controller belongs to, if available.
-
-Example:
-
- sbsc1: memory-controller@fe400000 {
- compatible = "renesas,sbsc-sh73a0";
- reg = <0xfe400000 0x400>;
- interrupts = <0 35 IRQ_TYPE_LEVEL_HIGH>,
- <0 36 IRQ_TYPE_LEVEL_HIGH>;
- interrupt-names = "sec", "temp";
- power-domains = <&pd_a4bc0>;

+title: STMicroelectronics Flexible Memory Controller 2 (FMC2) Bindings
+
+description: |
+ The FMC2 functional block makes the interface with: synchronous and
+ asynchronous static devices (such as PSNOR, PSRAM or other memory-mapped
+ peripherals) and NAND flash memories.
+ Its main purposes are:
+ - to translate AXI transactions into the appropriate external device
+ protocol
+ - to meet the access time requirements of the external devices
+ All external devices share the addresses, data and control signals with the
+ controller. Each external device is accessed by means of a unique Chip
+ Select. The FMC2 performs only one access at a time to an external device.

-ChromeOS Embedded Controller
-
-Google's ChromeOS EC is a Cortex-M device which talks to the AP and
-implements various function such as keyboard and battery charging.
-
-The EC can be connect through various means (I2C, SPI, LPC, RPMSG) and the
-compatible string used depends on the interface. Each connection method has
-its own driver which connects to the top level interface-agnostic EC driver.
-Other Linux driver (such as cros-ec-keyb for the matrix keyboard) connect to
-the top-level driver.
-
-Required properties (I2C):
-- compatible: "google,cros-ec-i2c"
-- reg: I2C slave address
-
-Required properties (SPI):
-- compatible: "google,cros-ec-spi"
-- reg: SPI chip select
-
-Required properties (RPMSG):
-- compatible: "google,cros-ec-rpmsg"
-
-Optional properties (SPI):
-- google,cros-ec-spi-pre-delay: Some implementations of the EC need a little
- time to wake up from sleep before they can receive SPI transfers at a high
- clock rate. This property specifies the delay, in usecs, between the
- assertion of the CS to the start of the first clock pulse.
-- google,cros-ec-spi-msg-delay: Some implementations of the EC require some
- additional processing time in order to accept new transactions. If the delay
- between transactions is not long enough the EC may not be able to respond
- properly to subsequent transactions and cause them to hang. This property
- specifies the delay, in usecs, introduced between transactions to account
- for the time required by the EC to get back into a state in which new data
- can be accepted.
-
-Required properties (LPC):
-- compatible: "google,cros-ec-lpc"
-- reg: List of (IO address, size) pairs defining the interface uses
-
-Optional properties (all):
-- google,has-vbc-nvram: Some implementations of the EC include a small
- nvram space used to store verified boot context data. This boolean flag
- is used to specify whether this nvram is present or not.
-
-Example for I2C:
-
-i2c@12ca0000 {
- cros-ec@1e {
- reg = <0x1e>;
- compatible = "google,cros-ec-i2c";
- interrupts = <14 0>;
- interrupt-parent = <&wakeup_eint>;
- wakeup-source;
- };
-
-
-Example for SPI:
-
-spi@131b0000 {
- ec@0 {
- compatible = "google,cros-ec-spi";
- reg = <0x0>;
- interrupts = <14 0>;
- interrupt-parent = <&wakeup_eint>;
- wakeup-source;
- spi-max-frequency = <5000000>;
- controller-data {
- cs-gpio = <&gpf0 3 4 3 0>;
- samsung,spi-cs;
- samsung,spi-feedback-delay = <2>;
- };
- };
-};
-
-
-Example for LPC is not supplied as it is not yet implemented.

-* ROHM BD71837 and BD71847 Power Management Integrated Circuit bindings
-
-BD71837MWV and BD71847MWV are programmable Power Management ICs for powering
-single-core, dual-core, and quad-core SoCs such as NXP-i.MX 8M. They are
-optimized for low BOM cost and compact solution footprint. BD71837MWV
-integrates 8 Buck regulators and 7 LDOs. BD71847MWV contains 6 Buck regulators
-and 6 LDOs.
-
-Datasheet for BD71837 is available at:
-https://www.rohm.com/datasheet/BD71837MWV/bd71837mwv-e
-Datasheet for BD71847 is available at:
-https://www.rohm.com/datasheet/BD71847AMWV/bd71847amwv-e
-
-Required properties:
- - compatible : Should be "rohm,bd71837" for bd71837
- "rohm,bd71847" for bd71847.
- - reg : I2C slave address.
- - interrupt-parent : Phandle to the parent interrupt controller.
- - interrupts : The interrupt line the device is connected to.
- - clocks : The parent clock connected to PMIC. If this is missing
- 32768 KHz clock is assumed.
- - #clock-cells : Should be 0.
- - regulators: : List of child nodes that specify the regulators.
- Please see ../regulator/rohm,bd71837-regulator.txt
-
-Optional properties:
-- clock-output-names : Should contain name for output clock.
-- rohm,reset-snvs-powered : Transfer BD718x7 to SNVS state at reset.
-
-The BD718x7 supports two different HW states as reset target states. States
-are called as SNVS and READY. At READY state all the PMIC power outputs go
-down and OTP is reload. At the SNVS state all other logic and external
-devices apart from the SNVS power domain are shut off. Please refer to NXP
-i.MX8 documentation for further information regarding SNVS state. When a
-reset is done via SNVS state the PMIC OTP data is not reload. This causes
-power outputs that have been under SW control to stay down when reset has
-switched power state to SNVS. If reset is done via READY state the power
-outputs will be returned to HW control by OTP loading. Thus the reset
-target state is set to READY by default. If SNVS state is used the boot
-crucial regulators must have the regulator-always-on and regulator-boot-on
-properties set in regulator node.
-
-- rohm,short-press-ms : Short press duration in milliseconds
-- rohm,long-press-ms : Long press duration in milliseconds
-
-Configure the "short press" and "long press" timers for the power button.
-Values are rounded to what hardware supports (500ms multiple for short and
-1000ms multiple for long). If these properties are not present the existing
-configuration (from bootloader or OTP) is not touched.
-
-Example:
-
- /* external oscillator node */
- osc: oscillator {
- compatible = "fixed-clock";
- #clock-cells = <1>;
- clock-frequency = <32768>;
- clock-output-names = "osc";
- };
-
- pmic: pmic@4b {
- compatible = "rohm,bd71837";
- reg = <0x4b>;
- interrupt-parent = <&gpio1>;
- interrupts = <29 GPIO_ACTIVE_LOW>;
- interrupt-names = "irq";
- #clock-cells = <0>;
- clocks = <&osc 0>;
- clock-output-names = "bd71837-32k-out";
- rohm,reset-snvs-powered;

-STMicroelectonics Multi-Function eXpander (STMFX) Core bindings
-
-ST Multi-Function eXpander (STMFX) is a slave controller using I2C for
-communication with the main MCU. Its main features are GPIO expansion, main
-MCU IDD measurement (IDD is the amount of current that flows through VDD) and
-resistive touchscreen controller.
-
-Required properties:
-- compatible: should be "st,stmfx-0300".
-- reg: I2C slave address of the device.
-- interrupts: interrupt specifier triggered by MFX_IRQ_OUT signal.
- Please refer to ../interrupt-controller/interrupt.txt
-
-Optional properties:
-- drive-open-drain: configure MFX_IRQ_OUT as open drain.
-- vdd-supply: phandle of the regulator supplying STMFX.
-
-Example:
-
- stmfx: stmfx@42 {
- compatible = "st,stmfx-0300";
- reg = <0x42>;
- interrupts = <8 IRQ_TYPE_EDGE_RISING>;
- interrupt-parent = <&gpioi>;
- vdd-supply = <&v3v3>;
- };

-Device Tree Bindings for the Arasan SDHCI Controller
-
- The bindings follow the mmc[1], clock[2], interrupt[3] and phy[4] bindings.
- Only deviations are documented here.
-
- [1] Documentation/devicetree/bindings/mmc/mmc.txt
- [2] Documentation/devicetree/bindings/clock/clock-bindings.txt
- [3] Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
- [4] Documentation/devicetree/bindings/phy/phy-bindings.txt
-
-Required Properties:
- - compatible: Compatibility string. One of:
- - "arasan,sdhci-8.9a": generic Arasan SDHCI 8.9a PHY
- - "arasan,sdhci-4.9a": generic Arasan SDHCI 4.9a PHY
- - "arasan,sdhci-5.1": generic Arasan SDHCI 5.1 PHY
- - "rockchip,rk3399-sdhci-5.1", "arasan,sdhci-5.1": rk3399 eMMC PHY
- For this device it is strongly suggested to include arasan,soc-ctl-syscon.
- - "ti,am654-sdhci-5.1", "arasan,sdhci-5.1": TI AM654 MMC PHY
- Note: This binding has been deprecated and moved to [5].
- - "intel,lgm-sdhci-5.1-emmc", "arasan,sdhci-5.1": Intel LGM eMMC PHY
- For this device it is strongly suggested to include arasan,soc-ctl-syscon.
-
- [5] Documentation/devicetree/bindings/mmc/sdhci-am654.txt
-
- - reg: From mmc bindings: Register location and length.
- - clocks: From clock bindings: Handles to clock inputs.
- - clock-names: From clock bindings: Tuple including "clk_xin" and "clk_ahb"
- - interrupts: Interrupt specifier
-
-Required Properties for "arasan,sdhci-5.1":
- - phys: From PHY bindings: Phandle for the Generic PHY for arasan.
- - phy-names: MUST be "phy_arasan".
-
-Optional Properties:
- - arasan,soc-ctl-syscon: A phandle to a syscon device (see ../mfd/syscon.txt)
- used to access core corecfg registers. Offsets of registers in this
- syscon are determined based on the main compatible string for the device.
- - clock-output-names: If specified, this will be the name of the card clock
- which will be exposed by this device. Required if #clock-cells is
- specified.
- - #clock-cells: If specified this should be the value <0>. With this property
- in place we will export a clock representing the Card Clock. This clock
- is expected to be consumed by our PHY. You must also specify
- - xlnx,fails-without-test-cd: when present, the controller doesn't work when
- the CD line is not connected properly, and the line is not connected
- properly. Test mode can be used to force the controller to function.
- - xlnx,int-clock-stable-broken: when present, the controller always reports
- that the internal clock is stable even when it is not.

-Optional properties:
-- fsl,wp-controller : Indicate to use controller internal write protection
-- fsl,delay-line : Specify the number of delay cells for override mode.
- This is used to set the clock delay for DLL(Delay Line) on override mode
- to select a proper data sampling window in case the clock quality is not good
- due to signal path is too long on the board. Please refer to eSDHC/uSDHC
- chapter, DLL (Delay Line) section in RM for details.
-- voltage-ranges : Specify the voltage range in case there are software
- transparent level shifters on the outputs of the controller. Two cells are
- required, first cell specifies minimum slot voltage (mV), second cell
- specifies maximum slot voltage (mV). Several ranges could be specified.
-- fsl,tuning-start-tap: Specify the start dealy cell point when send first CMD19
- in tuning procedure.
-- fsl,tuning-step: Specify the increasing delay cell steps in tuning procedure.
- The uSDHC use one delay cell as default increasing step to do tuning process.
- This property allows user to change the tuning step to more than one delay
- cells which is useful for some special boards or cards when the default
- tuning step can't find the proper delay window within limited tuning retries.

-* Ingenic JZ47xx MMC controllers
-
-This file documents the device tree properties used for the MMC controller in
-Ingenic JZ4740/JZ4780 SoCs. These are in addition to the core MMC properties
-described in mmc.txt.
-
-Required properties:
-- compatible: Should be one of the following:
- - "ingenic,jz4740-mmc" for the JZ4740
- - "ingenic,jz4725b-mmc" for the JZ4725B
- - "ingenic,jz4780-mmc" for the JZ4780
-- reg: Should contain the MMC controller registers location and length.
-- interrupts: Should contain the interrupt specifier of the MMC controller.
-- clocks: Clock for the MMC controller.
-
-Optional properties:
-- dmas: List of DMA specifiers with the controller specific format
- as described in the generic DMA client binding. A tx and rx
- specifier is required.
-- dma-names: RX and TX DMA request names.
- Should be "rx" and "tx", in that order.
-
-For additional details on DMA client bindings see ../dma/dma.txt.
-
-Example:
-
-mmc0: mmc@13450000 {
- compatible = "ingenic,jz4780-mmc";
- reg = <0x13450000 0x1000>;

-
-- clocks: Most controllers only have 1 clock source per channel. However, on
- some variations of this controller, the internal card detection
- logic that exists in this controller is sectioned off to be run by a
- separate second clock source to allow the main core clock to be turned
- off to save power.
- If 2 clocks are specified by the hardware, you must name them as
- "core" and "cd". If the controller only has 1 clock, naming is not
- required.
- Devices which have more than 1 clock are listed below:
- 2: R7S72100, R7S9210

-* Rockchip specific extensions to the Synopsys Designware Mobile
- Storage Host Controller
-
-The Synopsys designware mobile storage host controller is used to interface
-a SoC with storage medium such as eMMC or SD/MMC cards. This file documents
-differences between the core Synopsys dw mshc controller properties described
-by synopsys-dw-mshc.txt and the properties used by the Rockchip specific
-extensions to the Synopsys Designware Mobile Storage Host Controller.
-
-Required Properties:
-
-* compatible: should be
- - "rockchip,rk2928-dw-mshc": for Rockchip RK2928 and following,
- before RK3288
- - "rockchip,rk3288-dw-mshc": for Rockchip RK3288
- - "rockchip,rv1108-dw-mshc", "rockchip,rk3288-dw-mshc": for Rockchip RV1108
- - "rockchip,px30-dw-mshc", "rockchip,rk3288-dw-mshc": for Rockchip PX30
- - "rockchip,rk3036-dw-mshc", "rockchip,rk3288-dw-mshc": for Rockchip RK3036
- - "rockchip,rk3228-dw-mshc", "rockchip,rk3288-dw-mshc": for Rockchip RK322x
- - "rockchip,rk3328-dw-mshc", "rockchip,rk3288-dw-mshc": for Rockchip RK3328
- - "rockchip,rk3368-dw-mshc", "rockchip,rk3288-dw-mshc": for Rockchip RK3368
- - "rockchip,rk3399-dw-mshc", "rockchip,rk3288-dw-mshc": for Rockchip RK3399
-
-Optional Properties:
-* clocks: from common clock binding: if ciu-drive and ciu-sample are
- specified in clock-names, should contain handles to these clocks.
-
-* clock-names: Apart from the clock-names described in synopsys-dw-mshc.txt
- two more clocks "ciu-drive" and "ciu-sample" are supported. They are used
- to control the clock phases, "ciu-sample" is required for tuning high-
- speed modes.
-
-* rockchip,default-sample-phase: The default phase to set ciu-sample at
- probing, low speeds or in case where all phases work at tuning time.
- If not specified 0 deg will be used.
-
-* rockchip,desired-num-phases: The desired number of times that the host
- execute tuning when needed. If not specified, the host will do tuning
- for 360 times, namely tuning for each degree.
-
-Example:
-
- rkdwmmc0@12200000 {
- compatible = "rockchip,rk3288-dw-mshc";
- reg = <0x12200000 0x1000>;
- interrupts = <0 75 0>;
- #address-cells = <1>;
- #size-cells = <0>;

-* Synopsys Designware Mobile Storage Host Controller
-
-The Synopsys designware mobile storage host controller is used to interface
-a SoC with storage medium such as eMMC or SD/MMC cards. This file documents
-differences between the core mmc properties described by mmc.txt and the
-properties used by the Synopsys Designware Mobile Storage Host Controller.
-
-Required Properties:
-
-* compatible: should be
- - snps,dw-mshc: for controllers compliant with synopsys dw-mshc.
-* #address-cells: should be 1.
-* #size-cells: should be 0.
-
-# Slots (DEPRECATED): The slot specific information are contained within
- child-nodes with each child-node representing a supported slot. There should
- be atleast one child node representing a card slot. The name of the child node
- representing the slot is recommended to be slot@n where n is the unique number
- of the slot connected to the controller. The following are optional properties
- which can be included in the slot child node.
-
- * reg: specifies the physical slot number. The valid values of this
- property is 0 to (num-slots -1), where num-slots is the value
- specified by the num-slots property.
-
- * bus-width: as documented in mmc core bindings.
-
- * wp-gpios: specifies the write protect gpio line. The format of the
- gpio specifier depends on the gpio controller. If a GPIO is not used
- for write-protect, this property is optional.
-
- * disable-wp: If the wp-gpios property isn't present then (by default)
- we'd assume that the write protect is hooked up directly to the
- controller's special purpose write protect line (accessible via
- the WRTPRT register). However, it's possible that we simply don't
- want write protect. In that case specify 'disable-wp'.
- NOTE: This property is not required for slots known to always
- connect to eMMC or SDIO cards.
-
-Optional properties:
-
-* resets: phandle + reset specifier pair, intended to represent hardware
- reset signal present internally in some host controller IC designs.
- See Documentation/devicetree/bindings/reset/reset.txt for details.
-
-* reset-names: request name for using "resets" property. Must be "reset".
- (It will be used together with "resets" property.)
-
-* clocks: from common clock binding: handle to biu and ciu clocks for the
- bus interface unit clock and the card interface unit clock.
-
-* clock-names: from common clock binding: Shall be "biu" and "ciu".
- If the biu clock is missing we'll simply skip enabling it. If the
- ciu clock is missing we'll just assume that the clock is running at
- clock-frequency. It is an error to omit both the ciu clock and the
- clock-frequency.
-
-* clock-frequency: should be the frequency (in Hz) of the ciu clock. If this
- is specified and the ciu clock is specified then we'll try to set the ciu
- clock to this at probe time.
-
-* fifo-depth: The maximum size of the tx/rx fifo's. If this property is not
- specified, the default value of the fifo size is determined from the
- controller registers.
-
-* card-detect-delay: Delay in milli-seconds before detecting card after card
- insert event. The default value is 0.
-
-* data-addr: Override fifo address with value provided by DT. The default FIFO reg
- offset is assumed as 0x100 (version < 0x240A) and 0x200(version >= 0x240A) by
- driver. If the controller does not follow this rule, please use this property
- to set fifo address in device tree.
-
-* fifo-watermark-aligned: Data done irq is expected if data length is less than
- watermark in PIO mode. But fifo watermark is requested to be aligned with data
- length in some SoC so that TX/RX irq can be generated with data done irq. Add this
- watermark quirk to mark this requirement and force fifo watermark setting
- accordingly.
-
-* vmmc-supply: The phandle to the regulator to use for vmmc. If this is
- specified we'll defer probe until we can find this regulator.
-
-* dmas: List of DMA specifiers with the controller specific format as described
- in the generic DMA client binding. Refer to dma.txt for details.
-
-* dma-names: request names for generic DMA client binding. Must be "rx-tx".
- Refer to dma.txt for details.
-
-Aliases:
-
-- All the MSHC controller nodes should be represented in the aliases node using
- the following format 'mshc{n}' where n is a unique number for the alias.
-
-Example:
-
-The MSHC controller node can be split into two portions, SoC specific and
-board specific portions as listed below.

-* Ingenic JZ4780 NAND/ECC
-
-This file documents the device tree bindings for NAND flash devices on the
-JZ4780. NAND devices are connected to the NEMC controller (described in
-memory-controllers/ingenic,jz4780-nemc.txt), and thus NAND device nodes must
-be children of the NEMC node.
-
-Required NAND controller device properties:
-- compatible: Should be one of:
- * ingenic,jz4740-nand
- * ingenic,jz4725b-nand
- * ingenic,jz4780-nand
-- reg: For each bank with a NAND chip attached, should specify a bank number,
- an offset of 0 and a size of 0x1000000 (i.e. the whole NEMC bank).
-
-Optional NAND controller device properties:
-- ecc-engine: To make use of the hardware ECC controller, this
- property must contain a phandle for the ECC controller node. The required
- properties for this node are described below. If this is not specified,
- software ECC will be used instead.
-
-Optional children nodes:
-- Individual NAND chips are children of the NAND controller node.
-
-Required children node properties:
-- reg: An integer ranging from 1 to 6 representing the CS line to use.
-
-Optional children node properties:
-- nand-ecc-step-size: ECC block size in bytes.
-- nand-ecc-strength: ECC strength (max number of correctable bits).
-- nand-ecc-mode: String, operation mode of the NAND ecc mode. "hw" by default
-- nand-on-flash-bbt: boolean to enable on flash bbt option, if not present false
-- rb-gpios: GPIO specifier for the busy pin.
-- wp-gpios: GPIO specifier for the write protect pin.
-
-Optional child node of NAND chip nodes:
-- partitions: see Documentation/devicetree/bindings/mtd/partition.txt
-
-Example:
-
-nemc: nemc@13410000 {
- ...
-
- nandc: nand-controller@1 {
- compatible = "ingenic,jz4780-nand";
- reg = <1 0 0x1000000>; /* Bank 1 */
-
- #address-cells = <1>;
- #size-cells = <0>;
-
- ecc-engine = <&bch>;
-
- nand@1 {
- reg = <1>;
-
- nand-ecc-step-size = <1024>;
- nand-ecc-strength = <24>;
- nand-ecc-mode = "hw";
- nand-on-flash-bbt;
-
- rb-gpios = <&gpa 20 GPIO_ACTIVE_LOW>;
- wp-gpios = <&gpf 22 GPIO_ACTIVE_LOW>;
-
- partitions {
- #address-cells = <2>;
- #size-cells = <2>;
- ...
- }
- };
- };
-};
-
-The ECC controller is a separate SoC component used for error correction on
-NAND devices. The following is a description of the device properties for a
-ECC controller.
-

-- compatible: Should be one of:
- * ingenic,jz4740-ecc
- * ingenic,jz4725b-bch
- * ingenic,jz4780-bch
-- reg: Should specify the ECC controller registers location and length.
-- clocks: Clock for the ECC controller.

+Macronix NANDs Device Tree Bindings
+-----------------------------------
+
+Macronix NANDs support randomizer operation for scrambling user data,
+which can be enabled with a SET_FEATURE. The penalty when using the
+randomizer are subpage accesses prohibited and more time period needed
+for program operation, i.e., tPROG 300us to 340us (randomizer enabled).
+Enabling the randomizer is a one time persistent and non reversible
+operation.
+
+For more high-reliability concern, if subpage write is not available
+with hardware ECC and not enabled at UBI level, then enabling the
+randomizer is recommended by default by adding a new specific property
+in children nodes.
+
+Required NAND chip properties in children mode:
+- randomizer enable: should be "mxic,enable-randomizer-otp"
+
+Example:
+
+ nand: nand-controller@unit-address {
+
+ nand@0 {
+ reg = <0>;
+ mxic,enable-randomizer-otp;
+ };

+ Multiple M_CAN instances can share the same Message RAM
+ and each element(e.g Rx FIFO or Tx Buffer and etc) number
+ in Message RAM is also configurable, so this property is
+ telling driver how the shared or private Message RAM are

+
+ The format should be as follows:
+ <offset sidf_elems xidf_elems rxf0_elems rxf1_elems rxb_elems txe_elems txb_elems>
+ The 'offset' is an address offset of the Message RAM where
+ the following elements start from. This is usually set to

-Generic CAN transceiver Device Tree binding
-------------------------------
-
-CAN transceiver typically limits the max speed in standard CAN and CAN FD
-modes. Typically these limitations are static and the transceivers themselves
-provide no way to detect this limitation at runtime. For this situation,
-the "can-transceiver" node can be used.
-
-Required Properties:
- max-bitrate: a positive non 0 value that determines the max
- speed that CAN/CAN-FD can run. Any other value
- will be ignored.
-
-Examples:
-
-Based on Texas Instrument's TCAN1042HGV CAN Transceiver
-
-m_can0 {
- ....
- can-transceiver {
- max-bitrate = <5000000>;
- };
- ...

-Bosch MCAN controller Device Tree Bindings
--------------------------------------------------
-
-Required properties:
-- compatible : Should be "bosch,m_can" for M_CAN controllers
-- reg : physical base address and size of the M_CAN
- registers map and Message RAM
-- reg-names : Should be "m_can" and "message_ram"
-- interrupts : Should be the interrupt number of M_CAN interrupt
- line 0 and line 1, could be same if sharing
- the same interrupt.
-- interrupt-names : Should contain "int0" and "int1"
-- clocks : Clocks used by controller, should be host clock
- and CAN clock.
-- clock-names : Should contain "hclk" and "cclk"
-- pinctrl-<n> : Pinctrl states as described in bindings/pinctrl/pinctrl-bindings.txt
-- pinctrl-names : Names corresponding to the numbered pinctrl states
-- bosch,mram-cfg : Message RAM configuration data.
- Multiple M_CAN instances can share the same Message
- RAM and each element(e.g Rx FIFO or Tx Buffer and etc)
- number in Message RAM is also configurable,
- so this property is telling driver how the shared or
- private Message RAM are used by this M_CAN controller.
-
- The format should be as follows:
- <offset sidf_elems xidf_elems rxf0_elems rxf1_elems
- rxb_elems txe_elems txb_elems>
- The 'offset' is an address offset of the Message RAM
- where the following elements start from. This is
- usually set to 0x0 if you're using a private Message
- RAM. The remain cells are used to specify how many
- elements are used for each FIFO/Buffer.
-
- M_CAN includes the following elements according to user manual:
- 11-bit Filter 0-128 elements / 0-128 words
- 29-bit Filter 0-64 elements / 0-128 words
- Rx FIFO 0 0-64 elements / 0-1152 words
- Rx FIFO 1 0-64 elements / 0-1152 words
- Rx Buffers 0-64 elements / 0-1152 words
- Tx Event FIFO 0-32 elements / 0-64 words
- Tx Buffers 0-32 elements / 0-576 words
-
- Please refer to 2.4.1 Message RAM Configuration in
- Bosch M_CAN user manual for details.
-
-Optional Subnode:
-- can-transceiver : Can-transceiver subnode describing maximum speed
- that can be used for CAN/CAN-FD modes. See
- Documentation/devicetree/bindings/net/can/can-transceiver.txt
- for details.
-Example:
-SoC dtsi:
-m_can1: can@20e8000 {

Distributed Switch Architecture Device Tree Bindings
----------------------------------------------------
-Switches are true Linux devices and can be probed by any means. Once
-probed, they register to the DSA framework, passing a node
-pointer. This node is expected to fulfil the following binding, and
-may contain additional properties as required by the device it is
-embedded within.
-
-Required properties:
-
-- ports : A container for child nodes representing switch ports.
-
-Optional properties:
-
-- dsa,member : A two element list indicates which DSA cluster, and position
- within the cluster a switch takes. <0 0> is cluster 0,
- switch 0. <0 1> is cluster 0, switch 1. <1 0> is cluster 1,
- switch 0. A switch not part of any cluster (single device
- hanging off a CPU port) must not specify this property
-
-The ports container has the following properties
-
-Required properties:
-
-- #address-cells : Must be 1
-- #size-cells : Must be 0
-
-Each port children node must have the following mandatory properties:
-- reg : Describes the port address in the switch
-
-An uplink/downlink port between switches in the cluster has the following
-mandatory property:
-
-- link : Should be a list of phandles to other switch's DSA
- port. This port is used as the outgoing port
- towards the phandle ports. The full routing
- information must be given, not just the one hop
- routes to neighbouring switches.
-
-A CPU port has the following mandatory property:
-
-- ethernet : Should be a phandle to a valid Ethernet device node.
- This host device is what the switch port is
- connected to.
-
-A user port has the following optional property:
-
-- label : Describes the label associated with this port, which
- will become the netdev name.
-
-Port child nodes may also contain the following optional standardised
-properties, described in binding documents:
-
-- phy-handle : Phandle to a PHY on an MDIO bus. See
- Documentation/devicetree/bindings/net/ethernet.txt
- for details.
-
-- phy-mode : See
- Documentation/devicetree/bindings/net/ethernet.txt
- for details.
-
-- fixed-link : Fixed-link subnode describing a link to a non-MDIO
- managed entity. See
- Documentation/devicetree/bindings/net/fixed-link.txt
- for details.
-
-The MAC address will be determined using the optional properties
-defined in ethernet.txt.
-
-Example
-
-The following example shows three switches on three MDIO busses,
-linked into one DSA cluster.

+Microchip Ocelot switch driver family
+=====================================
+
+Felix
+-----
+
+Currently the switches supported by the felix driver are:
+
+- VSC9959 (Felix)
+- VSC9953 (Seville)
+
+The VSC9959 switch is found in the NXP LS1028A. It is a PCI device, part of the
+larger ENETC root complex. As a result, the ethernet-switch node is a sub-node
+of the PCIe root complex node and its "reg" property conforms to the parent
+node bindings:
+
+* reg: Specifies PCIe Device Number and Function Number of the endpoint device,
+ in this case for the Ethernet L2Switch it is PF5 (of device 0, bus 0).
+
+It does not require a "compatible" string.
+
+The interrupt line is used to signal availability of PTP TX timestamps and for
+TSN frame preemption.
+
+For the external switch ports, depending on board configuration, "phy-mode" and
+"phy-handle" are populated by board specific device tree instances. Ports 4 and
+5 are fixed as internal ports in the NXP LS1028A instantiation.
+
+The CPU port property ("ethernet") configures the feature called "NPI port" in
+the Ocelot hardware core. The CPU port in Ocelot is a set of queues, which are
+connected, in the Node Processor Interface (NPI) mode, to an Ethernet port.
+By default, in fsl-ls1028a.dtsi, the NPI port is assigned to the internal
+2.5Gbps port@4, but can be moved to the 1Gbps port@5, depending on the specific
+use case. Moving the NPI port to an external switch port is hardware possible,
+but there is no platform support for the Linux system on the LS1028A chip to
+operate as an entire slave DSA chip. NPI functionality (and therefore DSA
+tagging) is supported on a single port at a time.
+
+Any port can be disabled (and in fsl-ls1028a.dtsi, they are indeed all disabled
+by default, and should be enabled on a per-board basis). But if any external
+switch port is enabled at all, the ENETC PF2 (enetc_port2) should be enabled as

+title: Qualcomm IP Accelerator (IPA)

+
+description:
+ This binding describes the Qualcomm IPA. The IPA is capable of offloading
+ certain network processing tasks (e.g. filtering, routing, and NAT) from
+ the main processor.
+
+ The IPA sits between multiple independent "execution environments,"
+ including the Application Processor (AP) and the modem. The IPA presents
+ a Generic Software Interface (GSI) to each execution environment.
+ The GSI is an integral part of the IPA, but it is logically isolated
+ and has a distinct interrupt and a separately-defined address space.
+
+ See also soc/qcom/qcom,smp2p.txt and interconnect/interconnect.txt. See
+ iommu/iommu.txt and iommu/arm,smmu.yaml for more information about SMMU
+ bindings.

- - "renesas,etheravb-rcar-gen3" as a fallback for the above
- R-Car Gen3 and RZ/G2 devices.
-
- When compatible with the generic version, nodes must list the
- SoC-specific version corresponding to the platform first followed by
- the generic version.
-
-- reg: Offset and length of (1) the register block and (2) the stream buffer.
- The region for the register block is mandatory.
- The region for the stream buffer is optional, as it is only present on
- R-Car Gen2 and RZ/G1 SoCs, and on R-Car H3 (R8A7795), M3-W (R8A7796),
- and M3-N (R8A77965).
-- interrupts: A list of interrupt-specifiers, one for each entry in
- interrupt-names.
- If interrupt-names is not present, an interrupt specifier
- for a single muxed interrupt.
-- phy-mode: see ethernet.txt file in the same directory.
-- phy-handle: see ethernet.txt file in the same directory.
-- #address-cells: number of address cells for the MDIO bus, must be equal to 1.
-- #size-cells: number of size cells on the MDIO bus, must be equal to 0.
-- clocks: clock phandle and specifier pair.
-- pinctrl-0: phandle, referring to a default pin configuration node.
-
-Optional properties:
-- interrupt-names: A list of interrupt names.
- For the R-Car Gen 3 SoCs this property is mandatory;
- it should include one entry per channel, named "ch%u",
- where %u is the channel number ranging from 0 to 24.
- For other SoCs this property is optional; if present
- it should contain "mux" for a single muxed interrupt.
-- pinctrl-names: pin configuration state name ("default").
-- renesas,no-ether-link: boolean, specify when a board does not provide a proper
- AVB_LINK signal.
-- renesas,ether-link-active-low: boolean, specify when the AVB_LINK signal is
- active-low instead of normal active-high.

-* Socionext AVE ethernet controller
-
-This describes the devicetree bindings for AVE ethernet controller
-implemented on Socionext UniPhier SoCs.
-
-Required properties:
- - compatible: Should be
- - "socionext,uniphier-pro4-ave4" : for Pro4 SoC
- - "socionext,uniphier-pxs2-ave4" : for PXs2 SoC
- - "socionext,uniphier-ld11-ave4" : for LD11 SoC
- - "socionext,uniphier-ld20-ave4" : for LD20 SoC
- - "socionext,uniphier-pxs3-ave4" : for PXs3 SoC
- - reg: Address where registers are mapped and size of region.
- - interrupts: Should contain the MAC interrupt.
- - phy-mode: See ethernet.txt in the same directory. Allow to choose
- "rgmii", "rmii", "mii", or "internal" according to the PHY.
- The acceptable mode is SoC-dependent.
- - phy-handle: Should point to the external phy device.
- See ethernet.txt file in the same directory.
- - clocks: A phandle to the clock for the MAC.
- For Pro4 SoC, that is "socionext,uniphier-pro4-ave4",
- another MAC clock, GIO bus clock and PHY clock are also required.
- - clock-names: Should contain
- - "ether", "ether-gb", "gio", "ether-phy" for Pro4 SoC
- - "ether" for others
- - resets: A phandle to the reset control for the MAC. For Pro4 SoC,
- GIO bus reset is also required.
- - reset-names: Should contain
- - "ether", "gio" for Pro4 SoC
- - "ether" for others
- - socionext,syscon-phy-mode: A phandle to syscon with one argument
- that configures phy mode. The argument is the ID of MAC instance.
-
-The MAC address will be determined using the optional properties
-defined in ethernet.txt.
-
-Required subnode:
- - mdio: A container for child nodes representing phy nodes.
- See phy.txt in the same directory.
-
-Example:
-
- ether: ethernet@65000000 {

-STMicroelectronics STM32 / MCU DWMAC glue layer controller
-
-This file documents platform glue layer for stmmac.
-Please see stmmac.txt for the other unchanged properties.
-
-The device node has following properties.
-
-Required properties:
-- compatible: For MCU family should be "st,stm32-dwmac" to select glue, and
- "snps,dwmac-3.50a" to select IP version.
- For MPU family should be "st,stm32mp1-dwmac" to select
- glue, and "snps,dwmac-4.20a" to select IP version.
-- clocks: Must contain a phandle for each entry in clock-names.
-- clock-names: Should be "stmmaceth" for the host clock.
- Should be "mac-clk-tx" for the MAC TX clock.
- Should be "mac-clk-rx" for the MAC RX clock.
- For MPU family need to add also "ethstp" for power mode clock
-- interrupt-names: Should contain a list of interrupt names corresponding to
- the interrupts in the interrupts property, if available.
- Should be "macirq" for the main MAC IRQ
- Should be "eth_wake_irq" for the IT which wake up system
-- st,syscon : Should be phandle/offset pair. The phandle to the syscon node which
- encompases the glue register, and the offset of the control register.
-
-Optional properties:
-- clock-names: For MPU family "eth-ck" for PHY without quartz
-- st,eth-clk-sel (boolean) : set this property in RGMII PHY when you want to select RCC clock instead of ETH_CLK125.
-- st,eth-ref-clk-sel (boolean) : set this property in RMII mode when you have PHY without crystal 50MHz and want to select RCC clock instead of ETH_REF_CLK.

-* Texas Instruments - dp83867 Giga bit ethernet phy
-
-Required properties:
- - reg - The ID number for the phy, usually a small integer
- - ti,rx-internal-delay - RGMII Receive Clock Delay - see dt-bindings/net/ti-dp83867.h
- for applicable values. Required only if interface type is
- PHY_INTERFACE_MODE_RGMII_ID or PHY_INTERFACE_MODE_RGMII_RXID
- - ti,tx-internal-delay - RGMII Transmit Clock Delay - see dt-bindings/net/ti-dp83867.h
- for applicable values. Required only if interface type is
- PHY_INTERFACE_MODE_RGMII_ID or PHY_INTERFACE_MODE_RGMII_TXID
- - ti,fifo-depth - Transmitt FIFO depth- see dt-bindings/net/ti-dp83867.h
- for applicable values
-
-Note: If the interface type is PHY_INTERFACE_MODE_RGMII the TX/RX clock delays
- will be left at their default values, as set by the PHY's pin strapping.
- The default strapping will use a delay of 2.00 ns. Thus
- PHY_INTERFACE_MODE_RGMII, by default, does not behave as RGMII with no
- internal delay, but as PHY_INTERFACE_MODE_RGMII_ID. The device tree
- should use "rgmii-id" if internal delays are desired as this may be
- changed in future to cause "rgmii" mode to disable delays.
-
-Optional property:
- - ti,min-output-impedance - MAC Interface Impedance control to set
- the programmable output impedance to
- minimum value (35 ohms).
- - ti,max-output-impedance - MAC Interface Impedance control to set
- the programmable output impedance to
- maximum value (70 ohms).
- - ti,dp83867-rxctrl-strap-quirk - This denotes the fact that the
- board has RX_DV/RX_CTRL pin strapped in
- mode 1 or 2. To ensure PHY operation,
- there are specific actions that
- software needs to take when this pin is
- strapped in these modes. See data manual
- for details.
- - ti,clk-output-sel - Muxing option for CLK_OUT pin. See dt-bindings/net/ti-dp83867.h
- for applicable values. The CLK_OUT pin can also
- be disabled by this property. When omitted, the
- PHY's default will be left as is.
- - ti,sgmii-ref-clock-output-enable - This denotes which
- SGMII configuration is used (4 or 6-wire modes).
- Some MACs work with differential SGMII clock.
- See data manual for details.
-
-Note: ti,min-output-impedance and ti,max-output-impedance are mutually
- exclusive. When both properties are present ti,max-output-impedance
- takes precedence.
-
-Default child nodes are standard Ethernet PHY device
-nodes as described in Documentation/devicetree/bindings/net/phy.txt
-
-Example:
-
- ethernet-phy@0 {
- reg = <0>;
- ti,rx-internal-delay = <DP83867_RGMIIDCTL_2_25_NS>;
- ti,tx-internal-delay = <DP83867_RGMIIDCTL_2_75_NS>;

+title: The TI AM654x/J721E Common Platform Time Sync (CPTS) module Device Tree Bindings

+ - Sekhar Nori <nsekhar@ti.com>
+
+description: |+
+ The TI AM654x/J721E CPTS module is used to facilitate host control of time
+ sync operations.
+ Main features of CPTS module are
+ - selection of multiple external clock sources
+ - Software control of time sync events via interrupt or polling
+ - 64-bit timestamp mode in ns with PPM and nudge adjustment.
+ - hardware timestamp push inputs (HWx_TS_PUSH)
+ - timestamp counter compare output (TS_COMP)
+ - timestamp counter bit output (TS_SYNC)
+ - periodic Generator function outputs (TS_GENFx)
+ - Ethernet Enhanced Scheduled Traffic Operations (CPTS_ESTFn) (TSN)
+ - external hardware timestamp push inputs (HWx_TS_PUSH) timestamping
+
+ Depending on integration it enables compliance with the IEEE 1588-2008
+ standard for a precision clock synchronization protocol, Ethernet Enhanced
+ Scheduled Traffic Operations (CPTS_ESTFn) and PCIe Subsystem Precision Time
+ Measurement (PTM).
+
+ TI AM654x/J721E SoCs has several similar CPTS modules integrated into the
+ different parts of the system which could be synchronized with each other
+ - Main CPTS
+ - MCU CPSW CPTS with IEEE 1588-2008 support
+ - PCIe subsystem CPTS for PTM support
+
+ Depending on CPTS module integration and when CPTS is integral part of
+ another module (MCU CPSW for example) "compatible" and "reg" can
+ be omitted - parent module is fully responsible for CPTS enabling and
+ configuration.

+ For some SoCs, the CPU frequency subset and voltage value of each
+ OPP varies based on the silicon variant in use. Allwinner Process
+ Voltage Scaling Tables defines the voltage and frequency value based
+ on the speedbin blown in the efuse combination. The
+ sun50i-cpufreq-nvmem driver reads the efuse value from the SoC to

-* Synopsys DesignWare PCIe root complex in ECAM shift mode
-
-In some cases, firmware may already have configured the Synopsys DesignWare
-PCIe controller in RC mode with static ATU window mappings that cover all
-config, MMIO and I/O spaces in a [mostly] ECAM compatible fashion.
-In this case, there is no need for the OS to perform any low level setup
-of clocks, PHYs or device registers, nor is there any reason for the driver
-to reconfigure ATU windows for config and/or IO space accesses at runtime.
-
-In cases where the IP was synthesized with a minimum ATU window size of
-64 KB, it cannot be supported by the generic ECAM driver, because it
-requires special config space accessors that filter accesses to device #1
-and beyond on the first bus.
-
-Required properties:
-- compatible: "marvell,armada8k-pcie-ecam" or
- "socionext,synquacer-pcie-ecam" or
- "snps,dw-pcie-ecam" (must be preceded by a more specific match)
-
-Please refer to the binding document of "pci-host-ecam-generic" in the
-file host-generic-pci.txt for a description of the remaining required
-and optional properties.
-
-Example:
-
- pcie1: pcie@7f000000 {

-* Generic PCI host controller
-
-Firmware-initialised PCI host controllers and PCI emulations, such as the
-virtio-pci implementations found in kvmtool and other para-virtualised
-systems, do not require driver support for complexities such as regulator
-and clock management. In fact, the controller may not even require the
-configuration of a control interface by the operating system, instead
-presenting a set of fixed windows describing a subset of IO, Memory and
-Configuration Spaces.
-
-Such a controller can be described purely in terms of the standardized device
-tree bindings communicated in pci.txt:
-
-
-Properties of the host controller node:
-
-- compatible : Must be "pci-host-cam-generic" or "pci-host-ecam-generic"
- depending on the layout of configuration space (CAM vs
- ECAM respectively).
-
-- device_type : Must be "pci".
-
-- ranges : As described in IEEE Std 1275-1994, but must provide
- at least a definition of non-prefetchable memory. One
- or both of prefetchable Memory and IO Space may also
- be provided.
-
-- bus-range : Optional property (also described in IEEE Std 1275-1994)
- to indicate the range of bus numbers for this controller.
- If absent, defaults to <0 255> (i.e. all buses).
-
-- #address-cells : Must be 3.
-
-- #size-cells : Must be 2.
-
-- reg : The Configuration Space base address and size, as accessed
- from the parent bus. The base address corresponds to
- the first bus in the "bus-range" property. If no
- "bus-range" is specified, this will be bus 0 (the default).
-
-Properties of the /chosen node:
-
-- linux,pci-probe-only
- : Optional property which takes a single-cell argument.
- If '0', then Linux will assign devices in its usual manner,
- otherwise it will not try to assign devices and instead use
- them as they are configured already.
-
-Configuration Space is assumed to be memory-mapped (as opposed to being
-accessed via an ioport) and laid out with a direct correspondence to the
-geography of a PCI bus address by concatenating the various components to
-form an offset.
-
-For CAM, this 24-bit offset is:
-
- cfg_offset(bus, device, function, register) =
- bus << 16 | device << 11 | function << 8 | register
-
-While ECAM extends this by 4 bits to accommodate 4k of function space:
-
- cfg_offset(bus, device, function, register) =
- bus << 20 | device << 15 | function << 12 | register
-
-Interrupt mapping is exactly as described in `Open Firmware Recommended
-Practice: Interrupt Mapping' and requires the following properties:
-
-- #interrupt-cells : Must be 1
-
-- interrupt-map : <see aforementioned specification>
-
-- interrupt-map-mask : <see aforementioned specification>
-

+description: |
+ Firmware-initialised PCI host controllers and PCI emulations, such as the
+ virtio-pci implementations found in kvmtool and other para-virtualised
+ systems, do not require driver support for complexities such as regulator
+ and clock management. In fact, the controller may not even require the
+ configuration of a control interface by the operating system, instead
+ presenting a set of fixed windows describing a subset of IO, Memory and
+ Configuration Spaces.
+
+ Configuration Space is assumed to be memory-mapped (as opposed to being
+ accessed via an ioport) and laid out with a direct correspondence to the
+ geography of a PCI bus address by concatenating the various components to
+ form an offset.
+
+ For CAM, this 24-bit offset is:
+
+ cfg_offset(bus, device, function, register) =
+ bus << 16 | device << 11 | function << 8 | register
+
+ While ECAM extends this by 4 bits to accommodate 4k of function space:
+
+ cfg_offset(bus, device, function, register) =
+ bus << 20 | device << 15 | function << 12 | register
+

+ "fsl,lx2160a-pcie"
+- reg: base addresses and lengths of the PCIe controller register blocks.
+ "csr_axi_slave": Bridge config registers
+ "config_axi_slave": PCIe controller registers
+- interrupts: A list of interrupt outputs of the controller. Must contain an
+ entry for each entry in the interrupt-names property.
+- interrupt-names: It could include the following entries:
+ "intr": The interrupt that is asserted for controller interrupts
+ "aer": Asserted for aer interrupt when chip support the aer interrupt with
+ none MSI/MSI-X/INTx mode,but there is interrupt line for aer.
+ "pme": Asserted for pme interrupt when chip support the pme interrupt with
+ none MSI/MSI-X/INTx mode,but there is interrupt line for pme.
+- dma-coherent: Indicates that the hardware IP block can ensure the coherency
+ of the data transferred from/to the IP block. This can avoid the software
+ cache flush/invalid actions, and improve the performance significantly.

+description: |
+ The Calxeda Combination PHYs connect the SoC to the internal fabric
+ and to SATA connectors. The PHYs support multiple protocols (SATA,
+ SGMII, PCIe) and can be assigned to different devices (SATA or XGMAC
+ controller).
+ Programming the PHYs is typically handled by those device drivers,

-ROCKCHIP USB2.0 PHY WITH INNO IP BLOCK
-
-Required properties (phy (parent) node):
- - compatible : should be one of the listed compatibles:
- * "rockchip,rk3228-usb2phy"
- * "rockchip,rk3328-usb2phy"
- * "rockchip,rk3366-usb2phy"
- * "rockchip,rk3399-usb2phy"
- * "rockchip,rv1108-usb2phy"
- - reg : the address offset of grf for usb-phy configuration.
- - #clock-cells : should be 0.
- - clock-output-names : specify the 480m output clock name.
-
-Optional properties:
- - clocks : phandle + phy specifier pair, for the input clock of phy.
- - clock-names : input clock name of phy, must be "phyclk".
- - assigned-clocks : phandle of usb 480m clock.
- - assigned-clock-parents : parent of usb 480m clock, select between
- usb-phy output 480m and xin24m.
- Refer to clk/clock-bindings.txt for generic clock
- consumer properties.
- - rockchip,usbgrf : phandle to the syscon managing the "usb general
- register files". When set driver will request its
- phandle as one companion-grf for some special SoCs
- (e.g RV1108).
- - extcon : phandle to the extcon device providing the cable state for
- the otg phy.
-
-Required nodes : a sub-node is required for each port the phy provides.
- The sub-node name is used to identify host or otg port,
- and shall be the following entries:
- * "otg-port" : the name of otg port.
- * "host-port" : the name of host port.
-
-Required properties (port (child) node):
- - #phy-cells : must be 0. See ./phy-bindings.txt for details.
- - interrupts : specify an interrupt for each entry in interrupt-names.
- - interrupt-names : a list which should be one of the following cases:
- Regular case:
- * "otg-id" : for the otg id interrupt.
- * "otg-bvalid" : for the otg vbus interrupt.
- * "linestate" : for the host/otg linestate interrupt.
- Some SoCs use one interrupt with the above muxed together, so for these
- * "otg-mux" : otg-port interrupt, which mux otg-id/otg-bvalid/linestate
- to one.
-
-Optional properties:
- - phy-supply : phandle to a regulator that provides power to VBUS.
- See ./phy-bindings.txt for details.

-Qualcomm DWC3 HS AND SS PHY CONTROLLER
---------------------------------------
-
-DWC3 PHY nodes are defined to describe on-chip Synopsis Physical layer
-controllers. Each DWC3 PHY controller should have its own node.
-
-Required properties:
-- compatible: should contain one of the following:
- - "qcom,dwc3-hs-usb-phy" for High Speed Synopsis PHY controller
- - "qcom,dwc3-ss-usb-phy" for Super Speed Synopsis PHY controller
-- reg: offset and length of the DWC3 PHY controller register set
-- #phy-cells: must be zero
-- clocks: a list of phandles and clock-specifier pairs, one for each entry in
- clock-names.
-- clock-names: Should contain "ref" for the PHY reference clock
-
-Optional clocks:
- "xo" External reference clock
-
-Example:
- phy@100f8800 {

-TI am335x/am437x/dra7(am5)/dm814x CPSW3G Ethernet Subsystem supports
-two 10/100/1000 Ethernet ports with selectable G/MII, RMII, and RGMII interfaces.
-The interface mode is selected by configuring the MII mode selection register(s)
-(GMII_SEL) in the System Control Module chapter (SCM). GMII_SEL register(s) and
-bit fields placement in SCM are different between SoCs while fields meaning
-is the same.

-* Allwinner A1X Pin Controller
-
-The pins controlled by sunXi pin controller are organized in banks,
-each bank has 32 pins. Each pin has 7 multiplexing functions, with
-the first two functions being GPIO in and out. The configuration on
-the pins includes drive strength and pull-up.
-
-Required properties:
-- compatible: Should be one of the following (depending on your SoC):
- "allwinner,sun4i-a10-pinctrl"
- "allwinner,sun5i-a10s-pinctrl"
- "allwinner,sun5i-a13-pinctrl"
- "allwinner,sun6i-a31-pinctrl"
- "allwinner,sun6i-a31s-pinctrl"
- "allwinner,sun6i-a31-r-pinctrl"
- "allwinner,sun7i-a20-pinctrl"
- "allwinner,sun8i-a23-pinctrl"
- "allwinner,sun8i-a23-r-pinctrl"
- "allwinner,sun8i-a33-pinctrl"
- "allwinner,sun9i-a80-pinctrl"
- "allwinner,sun9i-a80-r-pinctrl"
- "allwinner,sun8i-a83t-pinctrl"
- "allwinner,sun8i-a83t-r-pinctrl"
- "allwinner,sun8i-h3-pinctrl"

- "allwinner,sun50i-h6-r-pinctrl"
- "allwinner,suniv-f1c100s-pinctrl"
- "nextthing,gr8-pinctrl"
-
-- reg: Should contain the register physical address and length for the
- pin controller.
-
-- clocks: phandle to the clocks feeding the pin controller:
- - "apb": the gated APB parent clock
- - "hosc": the high frequency oscillator in the system
- - "losc": the low frequency oscillator in the system
-
-Note: For backward compatibility reasons, the hosc and losc clocks are only
-required if you need to use the optional input-debounce property. Any new
-device tree should set them.
-
-Each pin bank, depending on the SoC, can have an associated regulator:
-
-- vcc-pa-supply: for the A10, A20, A31, A31s, A80 and R40 SoCs
-- vcc-pb-supply: for the A31, A31s, A80 and V3s SoCs
-- vcc-pc-supply: for the A10, A20, A31, A31s, A64, A80, H5, R40 and V3s SoCs
-- vcc-pd-supply: for the A23, A31, A31s, A64, A80, A83t, H3, H5 and R40 SoCs
-- vcc-pe-supply: for the A10, A20, A31, A31s, A64, A80, R40 and V3s SoCs
-- vcc-pf-supply: for the A10, A20, A31, A31s, A80, R40 and V3s SoCs
-- vcc-pg-supply: for the A10, A20, A31, A31s, A64, A80, H3, H5, R40 and V3s SoCs
-- vcc-ph-supply: for the A31, A31s and A80 SoCs
-- vcc-pl-supply: for the r-pinctrl of the A64, A80 and A83t SoCs
-- vcc-pm-supply: for the r-pinctrl of the A31, A31s and A80 SoCs
-
-Optional properties:
- - input-debounce: Array of debouncing periods in microseconds. One period per
- irq bank found in the controller. 0 if no setup required.
-
-
-Please refer to pinctrl-bindings.txt in this directory for details of the
-common pinctrl bindings used by client devices.
-
-A pinctrl node should contain at least one subnodes representing the
-pinctrl groups available on the machine. Each subnode will list the
-pins it needs, and how they should be configured, with regard to muxer
-configuration, drive strength and pullups. If one of these options is
-not set, its actual value will be unspecified.
-
-Allwinner A1X Pin Controller supports the generic pin multiplexing and
-configuration bindings. For details on each properties, you can refer to
- ./pinctrl-bindings.txt.
-
-Required sub-node properties:
- - pins
- - function
-
-Optional sub-node properties:
- - bias-disable
- - bias-pull-up
- - bias-pull-down
- - drive-strength
-
-*** Deprecated pin configuration and multiplexing binding
-
-Required subnode-properties:
-
-- allwinner,pins: List of strings containing the pin name.
-- allwinner,function: Function to mux the pins listed above to.
-
-Optional subnode-properties:
-- allwinner,drive: Integer. Represents the current sent to the pin
- 0: 10 mA
- 1: 20 mA
- 2: 30 mA
- 3: 40 mA
-- allwinner,pull: Integer.
- 0: No resistor
- 1: Pull-up resistor
- 2: Pull-down resistor
-
-Examples:
-
-pio: pinctrl@1c20800 {
- compatible = "allwinner,sun5i-a13-pinctrl";
- reg = <0x01c20800 0x400>;
- #address-cells = <1>;
- #size-cells = <0>;
-
- uart1_pins_a: uart1@0 {
- allwinner,pins = "PE10", "PE11";
- allwinner,function = "uart1";
- allwinner,drive = <0>;
- allwinner,pull = <0>;

- allwinner,function = "uart1";
- allwinner,drive = <0>;
- allwinner,pull = <0>;
- };
-};
-
-
-GPIO and interrupt controller
------------------------------
-
-This hardware also acts as a GPIO controller and an interrupt
-controller.
-
-Consumers that would want to refer to one or the other (or both)
-should provide through the usual *-gpios and interrupts properties a
-cell with 3 arguments, first the number of the bank, then the pin
-inside that bank, and finally the flags for the GPIO/interrupts.
-
-Example:
-
-xio: gpio@38 {
- compatible = "nxp,pcf8574a";
- reg = <0x38>;
-
- gpio-controller;
- #gpio-cells = <2>;
-
- interrupt-parent = <&pio>;
- interrupts = <6 0 IRQ_TYPE_EDGE_FALLING>;
- interrupt-controller;
- #interrupt-cells = <2>;
-};
-
-reg_usb1_vbus: usb1-vbus {
- compatible = "regulator-fixed";
- regulator-name = "usb1-vbus";
- regulator-min-microvolt = <5000000>;
- regulator-max-microvolt = <5000000>;
- gpio = <&pio 7 6 GPIO_ACTIVE_HIGH>;
-};

-Cirrus Logic Lochnagar Audio Development Board
-
-Lochnagar is an evaluation and development board for Cirrus Logic
-Smart CODEC and Amp devices. It allows the connection of most Cirrus
-Logic devices on mini-cards, as well as allowing connection of
-various application processor systems to provide a full evaluation
-platform. Audio system topology, clocking and power can all be
-controlled through the Lochnagar, allowing the device under test
-to be used in a variety of possible use cases.
-
-This binding document describes the binding for the pinctrl portion
-of the driver.
-
-Also see these documents for generic binding information:
- [1] GPIO : ../gpio/gpio.txt
- [2] Pinctrl: ../pinctrl/pinctrl-bindings.txt
-
-And these for relevant defines:
- [3] include/dt-bindings/pinctrl/lochnagar.h
-
-This binding must be part of the Lochnagar MFD binding:
- [4] ../mfd/cirrus,lochnagar.txt
-
-Required properties:
-
- - compatible : One of the following strings:
- "cirrus,lochnagar-pinctrl"
-
- - gpio-controller : Indicates this device is a GPIO controller.
- - #gpio-cells : Must be 2. The first cell is the pin number, see
- [3] for available pins and the second cell is used to specify
- optional parameters, see [1].
- - gpio-ranges : Range of pins managed by the GPIO controller, see
- [1]. Both the GPIO and Pinctrl base should be set to zero and the
- count to the appropriate of the LOCHNAGARx_PIN_NUM_GPIOS define,

+description: |
+ Lochnagar is an evaluation and development board for Cirrus Logic
+ Smart CODEC and Amp devices. It allows the connection of most Cirrus
+ Logic devices on mini-cards, as well as allowing connection of various

+ Audio system topology, clocking and power can all be controlled through
+ the Lochnagar, allowing the device under test to be used in a variety of
+ possible use cases.

-
-Required properties of parent mfd node:
- - pinctrl-names : must be "default"
- - pinctrl-0 : a phandle to the node containing the subnodes containing default
- configurations
-
-Required subnodes:
- One subnode is required to contain the default settings. It contains an
- arbitrary number of configuration subnodes, one for each group or pin
- configuration you want to apply as a default.
-
-Required properties of configuration subnodes:
- - groups : name of one pin group to configure. One of:
- aif1, aif2, aif3, aif4, mif1, mif2, mif3, pdmspk1, pdmspk2,
- dmic4, dmic5, dmic6,
- gpio1, gpio2, ..., gpio40
- The gpioN groups select the single pin of this name for configuration
-
-Optional properties of configuration subnodes:
- Any configuration option not explicitly listed in the dts will be left at
- chip default setting.
-
- - function : name of function to assign to this group. One of:
- aif1, aif2, aif3, aif4, mif1, mif2, mif3, pdmspk1, pdmspk2,

- - bias-disable : disable pull-up and pull-down
- - bias-bus-hold : enable buskeeper
- - bias-pull-up : output is pulled-up
- - bias-pull-down : output is pulled-down
- - drive-push-pull : CMOS output
- - drive-open-drain : open-drain output
- - drive-strength : drive strength in mA. Valid values are 4 or 8
- - input-schmitt-enable : enable schmitt-trigger mode
- - input-schmitt-disable : disable schmitt-trigger mode
- - input-debounce : A value of 0 disables debounce, a value !=0 enables

-Ingenic XBurst pin controller
-
-Please refer to pinctrl-bindings.txt in this directory for details of the
-common pinctrl bindings used by client devices, including the meaning of the
-phrase "pin configuration node".
-
-For the XBurst SoCs, pin control is tightly bound with GPIO ports. All pins may
-be used as GPIOs, multiplexed device functions are configured within the
-GPIO port configuration registers and it is typical to refer to pins using the
-naming scheme "PxN" where x is a character identifying the GPIO port with
-which the pin is associated and N is an integer from 0 to 31 identifying the
-pin within that GPIO port. For example PA0 is the first pin in GPIO port A, and
-PB31 is the last pin in GPIO port B. The jz4740 and the x1000 contains 4 GPIO
-ports, PA to PD, for a total of 128 pins. The jz4760, the jz4770 and the jz4780
-contains 6 GPIO ports, PA to PF, for a total of 192 pins.
-
-
-Required properties:
---------------------
-
- - compatible: One of:
- - "ingenic,jz4740-pinctrl"
- - "ingenic,jz4725b-pinctrl"
- - "ingenic,jz4760-pinctrl"
- - "ingenic,jz4760b-pinctrl"
- - "ingenic,jz4770-pinctrl"
- - "ingenic,jz4780-pinctrl"
- - "ingenic,x1000-pinctrl"
- - "ingenic,x1000e-pinctrl"
- - "ingenic,x1500-pinctrl"
- - reg: Address range of the pinctrl registers.
-
-
-Required properties for sub-nodes (GPIO chips):
------------------------------------------------
-
- - compatible: Must contain one of:
- - "ingenic,jz4740-gpio"
- - "ingenic,jz4760-gpio"
- - "ingenic,jz4770-gpio"
- - "ingenic,jz4780-gpio"
- - "ingenic,x1000-gpio"
- - reg: The GPIO bank number.
- - interrupt-controller: Marks the device node as an interrupt controller.
- - interrupts: Interrupt specifier for the controllers interrupt.
- - #interrupt-cells: Should be 2. Refer to
- ../interrupt-controller/interrupts.txt for more details.
- - gpio-controller: Marks the device node as a GPIO controller.
- - #gpio-cells: Should be 2. The first cell is the GPIO number and the second
- cell specifies GPIO flags, as defined in <dt-bindings/gpio/gpio.h>. Only the
- GPIO_ACTIVE_HIGH and GPIO_ACTIVE_LOW flags are supported.
- - gpio-ranges: Range of pins managed by the GPIO controller. Refer to
- ../gpio/gpio.txt for more details.
-
-
-Example:
---------
-
-pinctrl: pin-controller@10010000 {
- compatible = "ingenic,jz4740-pinctrl";
- reg = <0x10010000 0x400>;

- #interrupt-cells = <2>;
-
- interrupt-parent = <&intc>;
- interrupts = <28>;

== Generic pin multiplexing node content ==
-pin multiplexing nodes:
-
-function - the mux function to select
-groups - the list of groups to select with this function
- (either this or "pins" must be specified)
-pins - the list of pins to select with this function (either
- this or "groups" must be specified)
-
-Example:
-
-state_0_node_a {
- uart0 {
- function = "uart0";
- groups = "u0rxtx", "u0rtscts";
- };
-};
-state_1_node_a {
- spi0 {
- function = "spi0";
- groups = "spi0pins";
- };
-};
-state_2_node_a {
- function = "i2c0";
- pins = "mfio29", "mfio30";
-};
-
-Optionally an alternative binding can be used if more suitable depending on the
-pin controller hardware. For hardware where there is a large number of identical
-pin controller instances, naming each pin and function can easily become
-unmaintainable. This is especially the case if the same controller is used for
-different pins and functions depending on the SoC revision and packaging.
-
-For cases like this, the pin controller driver may use pinctrl-pin-array helper
-binding with a hardware based index and a number of pin configuration values:
-
-pincontroller {
- ... /* Standard DT properties for the device itself elided */
- #pinctrl-cells = <2>;
-
- state_0_node_a {
- pinctrl-pin-array = <
- 0 A_DELAY_PS(0) G_DELAY_PS(120)
- 4 A_DELAY_PS(0) G_DELAY_PS(360)
- ...
- >;
- };
- ...
-};
-
-Above #pinctrl-cells specifies the number of value cells in addition to the
-index of the registers. This is similar to the interrupts-extended binding with
-one exception. There is no need to specify the phandle for each entry as that
-is already known as the defined pins are always children of the pin controller
-node. Further having the phandle pointing to another pin controller would not
-currently work as the pinctrl framework uses named modes to group pins for each
-pin control device.
-
-The index for pinctrl-pin-array must relate to the hardware for the pinctrl
-registers, and must not be a virtual index of pin instances. The reason for
-this is to avoid mapping of the index in the dts files and the pin controller
-driver as it can change.
-
-For hardware where pin multiplexing configurations have to be specified for
-each single pin the number of required sub-nodes containing "pin" and
-"function" properties can quickly escalate and become hard to write and
-maintain.
-
-For cases like this, the pin controller driver may use the pinmux helper
-property, where the pin identifier is provided with mux configuration settings
-in a pinmux group. A pinmux group consists of the pin identifier and mux
-settings represented as a single integer or an array of integers.
-
-The pinmux property accepts an array of pinmux groups, each of them describing
-a single pin multiplexing configuration.
-
-pincontroller {
- state_0_node_a {
- pinmux = <PINMUX_GROUP>, <PINMUX_GROUP>, ...;
- };
-};
-
-Each individual pin controller driver bindings documentation shall specify
-how pin IDs and pin multiplexing configuration are defined and assembled
-together in a pinmux group.

-for all hardware or binding structures. Each individual binding document
-should state which of these generic properties, if any, are used, and the
-structure of the DT nodes that contain these properties.
-
-Supported generic properties are:
-
-pins - the list of pins that properties in the node
- apply to (either this, "group" or "pinmux" has to be
- specified)
-group - the group to apply the properties to, if the driver

-output-low - set the pin to output mode with low level
-output-high - set the pin to output mode with high level
-sleep-hardware-state - indicate this is sleep related state which will be programmed
- into the registers for the sleep state.
-slew-rate - set the slew rate
-skew-delay - this affects the expected clock skew on input pins
- and the delay before latching a value to an output
- pin. Typically indicates how many double-inverters are
- used to delay the signal.

-
-state_0_node_a {
- cts_rxd {
- pins = "GPIO0_AJ5", "GPIO2_AH4"; /* CTS+RXD */
- bias-pull-up;
- };
-};

- pins = "GPIO1_AJ3", "GPIO3_AH3"; /* RTS+TXD */
- output-high;
- };
-};
-state_2_node_a {
- foo {
- group = "foo-group";
- bias-pull-up;
- };
-};
-state_3_node_a {
- mux {
- pinmux = <GPIOx_PINm_MUXn>, <GPIOx_PINj_MUXk)>;
- input-enable;
- };
-};

-Some of the generic properties take arguments. For those that do, the
-arguments are described below.
-
-- pins takes a list of pin names or IDs as a required argument. The specific
- binding for the hardware defines:
- - Whether the entries are integers or strings, and their meaning.
-
-- pinmux takes a list of pin IDs and mux settings as required argument. The
- specific bindings for the hardware defines:
- - How pin IDs and mux settings are defined and assembled together in a single
- integer or an array of integers.
-
-- bias-pull-up, -down and -pin-default take as optional argument on hardware
- supporting it the pull strength in Ohm. bias-disable will disable the pull.
-
-- drive-strength takes as argument the target strength in mA.
-
-- drive-strength-microamp takes as argument the target strength in uA.
-
-- input-debounce takes the debounce time in usec as argument
- or 0 to disable debouncing

+title: Generic pin multiplexing node schema
+
+maintainers:
+ - Linus Walleij <linus.walleij@linaro.org>
+
+description: |
+ The contents of the pin configuration child nodes are defined by the binding
+ for the individual pin controller device. The pin configuration nodes need not
+ be direct children of the pin controller device; they may be grandchildren,
+ for example. Whether this is legal, and whether there is any interaction
+ between the child and intermediate parent nodes, is again defined entirely by
+ the binding for the individual pin controller device.
+
+ While not required to be used, there are 3 generic forms of pin muxing nodes
+ which pin controller devices can use.
+
+ pin multiplexing nodes:
+
+ Example:
+
+ state_0_node_a {
+ uart0 {
+ function = "uart0";
+ groups = "u0rxtx", "u0rtscts";
+ };
+ };
+ state_1_node_a {
+ spi0 {
+ function = "spi0";
+ groups = "spi0pins";
+ };
+ };
+ state_2_node_a {
+ function = "i2c0";
+ pins = "mfio29", "mfio30";
+ };
+
+ Optionally an alternative binding can be used if more suitable depending on the
+ pin controller hardware. For hardware where there is a large number of identical
+ pin controller instances, naming each pin and function can easily become
+ unmaintainable. This is especially the case if the same controller is used for
+ different pins and functions depending on the SoC revision and packaging.
+
+ For cases like this, the pin controller driver may use pinctrl-pin-array helper
+ binding with a hardware based index and a number of pin configuration values:
+
+ pincontroller {
+ ... /* Standard DT properties for the device itself elided */
+ #pinctrl-cells = <2>;
+
+ state_0_node_a {
+ pinctrl-pin-array = <
+ 0 A_DELAY_PS(0) G_DELAY_PS(120)
+ 4 A_DELAY_PS(0) G_DELAY_PS(360)
+ ...
+ >;
+ };
+ ...
+ };
+
+ Above #pinctrl-cells specifies the number of value cells in addition to the
+ index of the registers. This is similar to the interrupts-extended binding with
+ one exception. There is no need to specify the phandle for each entry as that
+ is already known as the defined pins are always children of the pin controller
+ node. Further having the phandle pointing to another pin controller would not
+ currently work as the pinctrl framework uses named modes to group pins for each
+ pin control device.
+
+ The index for pinctrl-pin-array must relate to the hardware for the pinctrl
+ registers, and must not be a virtual index of pin instances. The reason for
+ this is to avoid mapping of the index in the dts files and the pin controller
+ driver as it can change.
+
+ For hardware where pin multiplexing configurations have to be specified for
+ each single pin the number of required sub-nodes containing "pin" and
+ "function" properties can quickly escalate and become hard to write and
+ maintain.
+
+ For cases like this, the pin controller driver may use the pinmux helper
+ property, where the pin identifier is provided with mux configuration settings
+ in a pinmux group. A pinmux group consists of the pin identifier and mux
+ settings represented as a single integer or an array of integers.
+
+ The pinmux property accepts an array of pinmux groups, each of them describing
+ a single pin multiplexing configuration.
+
+ pincontroller {
+ state_0_node_a {
+ pinmux = <PINMUX_GROUP>, <PINMUX_GROUP>, ...;
+ };
+ };
+
+ Each individual pin controller driver bindings documentation shall specify
+ how pin IDs and pin multiplexing configuration are defined and assembled
+ together in a pinmux group.

+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the meaning of the
+phrase "pin configuration node".
+
+The pin configuration nodes act as a container for an arbitrary number of
+subnodes. Each of these subnodes represents some desired configuration for a
+pin, a group, or a list of pins or groups. This configuration can include the
+mux function to select on those pin(s)/group(s), and various pin configuration
+parameters, such as pull-up, drive strength, etc.
+
+
+PIN CONFIGURATION NODES:
+
+The name of each subnode is not important; all subnodes should be enumerated
+and processed purely based on their content.
+
+Each subnode only affects those parameters that are explicitly listed. In
+other words, a subnode that lists a mux function but no pin configuration
+parameters implies no information about any pin configuration parameters.
+Similarly, a pin subnode that describes a pullup parameter implies no
+information about e.g. the mux function.
+
+
+The following generic properties as defined in pinctrl-bindings.txt are valid
+to specify in a pin configuration subnode:
+
+- pins:
+ Usage: required
+ Value type: <string-array>
+ Definition: List of gpio pins affected by the properties specified in
+ this subnode.
+
+ Valid pins are:
+ gpio0-gpio145
+ Supports mux, bias and drive-strength
+
+ sdc1_clk, sdc1_cmd, sdc1_data,
+ sdc2_clk, sdc2_cmd, sdc2_data,
+ sdc3_clk, sdc3_cmd, sdc3_data
+ Supports bias and drive-strength
+
+- function:
+ Usage: required
+ Value type: <string>
+ Definition: Specify the alternative function to be configured for the

-
- - reg: Base address and length of each memory resource used by the pin
- controller hardware module.
-
-Optional properties:
-
- - #gpio-range-cells: Mandatory when the PFC doesn't handle GPIO, forbidden
- otherwise. Should be 3.
-
- - interrupts-extended: Specify the interrupts associated with external
- IRQ pins. This property is mandatory when the PFC handles GPIOs and
- forbidden otherwise. When specified, it must contain one interrupt per
- external IRQ, sorted by external IRQ number.
-
-The PFC node also acts as a container for pin configuration nodes. Please refer
-to pinctrl-bindings.txt in this directory for the definition of the term "pin
-configuration node" and for the common pinctrl bindings used by client devices.
-
-Each pin configuration node represents a desired configuration for a pin, a
-pin group, or a list of pins or pin groups. The configuration can include the
-function to select on those pin(s) and pin configuration parameters (such as
-pull-up and pull-down).
-
-Pin configuration nodes contain pin configuration properties, either directly
-or grouped in child subnodes. Both pin muxing and configuration parameters can
-be grouped in that way and referenced as a single pin configuration node by
-client devices.
-
-A configuration node or subnode must reference at least one pin (through the
-pins or pin groups properties) and contain at least a function or one
-configuration parameter. When the function is present only pin groups can be
-used to reference pins.
-
-All pin configuration nodes and subnodes names are ignored. All of those nodes
-are parsed through phandles and processed purely based on their content.
-
-Pin Configuration Node Properties:
-
-- pins : An array of strings, each string containing the name of a pin.
-- groups : An array of strings, each string containing the name of a pin
- group.
-
-- function: A string containing the name of the function to mux to the pin
- group(s) specified by the groups property.
-
- Valid values for pin, group and function names can be found in the group and
- function arrays of the PFC data file corresponding to the SoC
- (drivers/pinctrl/sh-pfc/pfc-*.c)
-
-The pin configuration parameters use the generic pinconf bindings defined in
-pinctrl-bindings.txt in this directory. The supported parameters are
-bias-disable, bias-pull-up, bias-pull-down, drive-strength and power-source. For
-pins that have a configurable I/O voltage, the power-source value should be the
-nominal I/O voltage in millivolts.
-
-
-GPIO
-----
-
-On SH73A0, R8A73A4 and R8A7740 the PFC node is also a GPIO controller node.
-
-Required Properties:
-
- - gpio-controller: Marks the device node as a gpio controller.
-
- - #gpio-cells: Should be 2. The first cell is the GPIO number and the second
- cell specifies GPIO flags, as defined in <dt-bindings/gpio/gpio.h>. Only the
- GPIO_ACTIVE_HIGH and GPIO_ACTIVE_LOW flags are supported.
-
-The syntax of the gpio specifier used by client nodes should be the following
-with values derived from the SoC user manual.
-
- <[phandle of the gpio controller node]
- [pin number within the gpio controller]
- [flags]>
-
-On other mach-shmobile platforms GPIO is handled by the gpio-rcar driver.
-Please refer to Documentation/devicetree/bindings/gpio/renesas,gpio-rcar.txt
-for documentation of the GPIO device tree bindings on those platforms.

-Renesas RZ/A1 combined Pin and GPIO controller
-
-The Renesas SoCs of the RZ/A1 family feature a combined Pin and GPIO controller,
-named "Ports" in the hardware reference manual.
-Pin multiplexing and GPIO configuration is performed on a per-pin basis
-writing configuration values to per-port register sets.
-Each "port" features up to 16 pins, each of them configurable for GPIO
-function (port mode) or in alternate function mode.
-Up to 8 different alternate function modes exist for each single pin.
-
-Pin controller node
--------------------
-
-Required properties:
- - compatible: should be:
- - "renesas,r7s72100-ports": for RZ/A1H
- - "renesas,r7s72101-ports", "renesas,r7s72100-ports": for RZ/A1M
- - "renesas,r7s72102-ports": for RZ/A1L
-
- - reg
- address base and length of the memory area where the pin controller
- hardware is mapped to.
-
-Example:
-Pin controller node for RZ/A1H SoC (r7s72100)
-
-pinctrl: pin-controller@fcfe3000 {
- compatible = "renesas,r7s72100-ports";
-
- reg = <0xfcfe3000 0x4230>;
-};
-
-Sub-nodes
----------
-
-The child nodes of the pin controller node describe a pin multiplexing
-function or a GPIO controller alternatively.
-
-- Pin multiplexing sub-nodes:
- A pin multiplexing sub-node describes how to configure a set of
- (or a single) pin in some desired alternate function mode.
- A single sub-node may define several pin configurations.
- A few alternate function require special pin configuration flags to be
- supplied along with the alternate function configuration number.
- The hardware reference manual specifies when a pin function requires
- "software IO driven" mode to be specified. To do so use the generic
- properties from the <include/linux/pinctrl/pinconf_generic.h> header file
- to instruct the pin controller to perform the desired pin configuration
- operation.
- Please refer to pinctrl-bindings.txt to get to know more on generic
- pin properties usage.
-
- The allowed generic formats for a pin multiplexing sub-node are the
- following ones:
-
- node-1 {
- pinmux = <PIN_ID_AND_MUX>, <PIN_ID_AND_MUX>, ... ;
- GENERIC_PINCONFIG;
- };
-
- node-2 {
- sub-node-1 {
- pinmux = <PIN_ID_AND_MUX>, <PIN_ID_AND_MUX>, ... ;
- GENERIC_PINCONFIG;
- };
-
- sub-node-2 {
- pinmux = <PIN_ID_AND_MUX>, <PIN_ID_AND_MUX>, ... ;
- GENERIC_PINCONFIG;
- };
-
- ...
-
- sub-node-n {
- pinmux = <PIN_ID_AND_MUX>, <PIN_ID_AND_MUX>, ... ;
- GENERIC_PINCONFIG;
- };
- };
-
- Use the second format when pins part of the same logical group need to have
- different generic pin configuration flags applied.
-
- Client sub-nodes shall refer to pin multiplexing sub-nodes using the phandle
- of the most external one.
-
- Eg.
-
- client-1 {
- ...
- pinctrl-0 = <&node-1>;
- ...
- };
-
- client-2 {
- ...
- pinctrl-0 = <&node-2>;
- ...
- };
-
- Required properties:
- - pinmux:
- integer array representing pin number and pin multiplexing configuration.
- When a pin has to be configured in alternate function mode, use this
- property to identify the pin by its global index, and provide its
- alternate function configuration number along with it.
- When multiple pins are required to be configured as part of the same
- alternate function they shall be specified as members of the same
- argument list of a single "pinmux" property.
- Helper macros to ease assembling the pin index from its position
- (port where it sits on and pin number) and alternate function identifier
- are provided by the pin controller header file at:
- <include/dt-bindings/pinctrl/r7s72100-pinctrl.h>
- Integers values in "pinmux" argument list are assembled as:
- ((PORT * 16 + PIN) | MUX_FUNC << 16)
-
- Optional generic properties:
- - input-enable:
- enable input bufer for pins requiring software driven IO input
- operations.
- - output-high:
- enable output buffer for pins requiring software driven IO output
- operations. output-low can be used alternatively, as line value is
- ignored by the driver.
-
- The hardware reference manual specifies when a pin has to be configured to
- work in bi-directional mode and when the IO direction has to be specified
- by software. Bi-directional pins are managed by the pin controller driver
- internally, while software driven IO direction has to be explicitly
- selected when multiple options are available.
-
- Example:
- A serial communication interface with a TX output pin and an RX input pin.
-
- &pinctrl {
- scif2_pins: serial2 {
- pinmux = <RZA1_PINMUX(3, 0, 6)>, <RZA1_PINMUX(3, 2, 4)>;
- };
- };
-
- Pin #0 on port #3 is configured as alternate function #6.
- Pin #2 on port #3 is configured as alternate function #4.
-
- Example 2:
- I2c master: both SDA and SCL pins need bi-directional operations
-
- &pinctrl {
- i2c2_pins: i2c2 {
- pinmux = <RZA1_PINMUX(1, 4, 1)>, <RZA1_PINMUX(1, 5, 1)>;
- };
- };
-
- Pin #4 on port #1 is configured as alternate function #1.
- Pin #5 on port #1 is configured as alternate function #1.
- Both need to work in bi-directional mode, the driver manages this internally.
-
- Example 3:
- Multi-function timer input and output compare pins.
- Configure TIOC0A as software driven input and TIOC0B as software driven
- output.
-
- &pinctrl {
- tioc0_pins: tioc0 {
- tioc0_input_pins {
- pinumx = <RZA1_PINMUX(4, 0, 2)>;
- input-enable;
- };
-
- tioc0_output_pins {
- pinmux = <RZA1_PINMUX(4, 1, 1)>;
- output-enable;
- };
- };
- };
-
- &tioc0 {
- ...
- pinctrl-0 = <&tioc0_pins>;
- ...
- };
-
- Pin #0 on port #4 is configured as alternate function #2 with IO direction
- specified by software as input.
- Pin #1 on port #4 is configured as alternate function #1 with IO direction
- specified by software as output.
-
-- GPIO controller sub-nodes:
- Each port of the r7s72100 pin controller hardware is itself a GPIO controller.
- Different SoCs have different numbers of available pins per port, but
- generally speaking, each of them can be configured in GPIO ("port") mode
- on this hardware.
- Describe GPIO controllers using sub-nodes with the following properties.
-
- Required properties:
- - gpio-controller
- empty property as defined by the GPIO bindings documentation.
- - #gpio-cells
- number of cells required to identify and configure a GPIO.
- Shall be 2.
- - gpio-ranges
- Describes a GPIO controller specifying its specific pin base, the pin
- base in the global pin numbering space, and the number of controlled
- pins, as defined by the GPIO bindings documentation. Refer to
- Documentation/devicetree/bindings/gpio/gpio.txt file for a more detailed
- description.
-
- Example:
- A GPIO controller node, controlling 16 pins indexed from 0.
- The GPIO controller base in the global pin indexing space is pin 48, thus

-
-- Pin multiplexing sub-nodes:
- A pin multiplexing sub-node describes how to configure a set of
- (or a single) pin in some desired alternate function mode.
- The values for the pinmux properties are a combination of port name, pin
- number and the desired function index. Use the RZA2_PINMUX macro located
- in include/dt-bindings/pinctrl/r7s9210-pinctrl.h to easily define these.
- For assigning GPIO pins, use the macro RZA2_PIN also in r7s9210-pinctrl.h
- to express the desired port pin.
-
- Required properties:
- - pinmux:
- integer array representing pin number and pin multiplexing configuration.
- When a pin has to be configured in alternate function mode, use this
- property to identify the pin by its global index, and provide its
- alternate function configuration number along with it.
- When multiple pins are required to be configured as part of the same
- alternate function they shall be specified as members of the same

-
- Example: Board specific pins configuration
-
- &pinctrl {

-Renesas RZ/N1 SoC Pinctrl node description.
-
-Pin controller node
--------------------
-Required properties:
-- compatible: SoC-specific compatible string "renesas,<soc-specific>-pinctrl"
- followed by "renesas,rzn1-pinctrl" as fallback. The SoC-specific compatible
- strings must be one of:
- "renesas,r9a06g032-pinctrl" for RZ/N1D
- "renesas,r9a06g033-pinctrl" for RZ/N1S
-- reg: Address base and length of the memory area where the pin controller
- hardware is mapped to.
-- clocks: phandle for the clock, see the description of clock-names below.
-- clock-names: Contains the name of the clock:
- "bus", the bus clock, sometimes described as pclk, for register accesses.
-
-Example:
- pinctrl: pin-controller@40067000 {
- compatible = "renesas,r9a06g032-pinctrl", "renesas,rzn1-pinctrl";
- reg = <0x40067000 0x1000>, <0x51000000 0x480>;
- clocks = <&sysctrl R9A06G032_HCLK_PINCONFIG>;
- clock-names = "bus";
- };
-
-Sub-nodes
----------
-
-The child nodes of the pin controller node describe a pin multiplexing
-function.
-
-- Pin multiplexing sub-nodes:
- A pin multiplexing sub-node describes how to configure a set of
- (or a single) pin in some desired alternate function mode.
- A single sub-node may define several pin configurations.
- Please refer to pinctrl-bindings.txt to get to know more on generic
- pin properties usage.
-
- The allowed generic formats for a pin multiplexing sub-node are the
- following ones:
-
- node-1 {
- pinmux = <PIN_ID_AND_MUX>, <PIN_ID_AND_MUX>, ... ;
- GENERIC_PINCONFIG;
- };
-
- node-2 {
- sub-node-1 {
- pinmux = <PIN_ID_AND_MUX>, <PIN_ID_AND_MUX>, ... ;
- GENERIC_PINCONFIG;
- };
-
- sub-node-2 {
- pinmux = <PIN_ID_AND_MUX>, <PIN_ID_AND_MUX>, ... ;
- GENERIC_PINCONFIG;
- };
-
- ...
-
- sub-node-n {
- pinmux = <PIN_ID_AND_MUX>, <PIN_ID_AND_MUX>, ... ;
- GENERIC_PINCONFIG;
- };
- };
-
- node-3 {
- pinmux = <PIN_ID_AND_MUX>, <PIN_ID_AND_MUX>, ... ;
- GENERIC_PINCONFIG;
-
- sub-node-1 {
- pinmux = <PIN_ID_AND_MUX>, <PIN_ID_AND_MUX>, ... ;
- GENERIC_PINCONFIG;
- };
-
- ...
-
- sub-node-n {
- pinmux = <PIN_ID_AND_MUX>, <PIN_ID_AND_MUX>, ... ;
- GENERIC_PINCONFIG;
- };
- };
-
- Use the latter two formats when pins part of the same logical group need to
- have different generic pin configuration flags applied. Note that the generic
- pinconfig in node-3 does not apply to the sub-nodes.
-
- Client sub-nodes shall refer to pin multiplexing sub-nodes using the phandle
- of the most external one.
-
- Eg.
-
- client-1 {
- ...
- pinctrl-0 = <&node-1>;
- ...
- };
-
- client-2 {
- ...
- pinctrl-0 = <&node-2>;
- ...
- };
-
- Required properties:
- - pinmux:
- integer array representing pin number and pin multiplexing configuration.
- When a pin has to be configured in alternate function mode, use this
- property to identify the pin by its global index, and provide its
- alternate function configuration number along with it.
- When multiple pins are required to be configured as part of the same
- alternate function they shall be specified as members of the same
- argument list of a single "pinmux" property.
- Integers values in the "pinmux" argument list are assembled as:
- (PIN | MUX_FUNC << 8)
- where PIN directly corresponds to the pl_gpio pin number and MUX_FUNC is
- one of the alternate function identifiers defined in:
- <include/dt-bindings/pinctrl/rzn1-pinctrl.h>
- These identifiers collapse the IO Multiplex Configuration Level 1 and
- Level 2 numbers that are detailed in the hardware reference manual into a
- single number. The identifiers for Level 2 are simply offset by 10.
- Additional identifiers are provided to specify the MDIO source peripheral.
-
- Optional generic pinconf properties:
- - bias-disable - disable any pin bias
- - bias-pull-up - pull up the pin with 50 KOhm
- - bias-pull-down - pull down the pin with 50 KOhm
- - bias-high-impedance - high impedance mode
- - drive-strength - sink or source at most 4, 6, 8 or 12 mA
-
- Example:
- A serial communication interface with a TX output pin and an RX input pin.
-
- &pinctrl {
- pins_uart0: pins_uart0 {
- pinmux = <
- RZN1_PINMUX(103, RZN1_FUNC_UART0_I) /* UART0_TXD */
- RZN1_PINMUX(104, RZN1_FUNC_UART0_I) /* UART0_RXD */
- >;
- };
- };
-
- Example 2:
- Here we set the pull up on the RXD pin of the UART.
-
- &pinctrl {
- pins_uart0: pins_uart0 {
- pinmux = <RZN1_PINMUX(103, RZN1_FUNC_UART0_I)>; /* TXD */
-
- pins_uart6_rx {
- pinmux = <RZN1_PINMUX(104, RZN1_FUNC_UART0_I)>; /* RXD */
- bias-pull-up;
- };
- };

+QCOM CPR (Core Power Reduction)
+
+CPR (Core Power Reduction) is a technology to reduce core power on a CPU
+or other device. Each OPP of a device corresponds to a "corner" that has
+a range of valid voltages for a particular frequency. While the device is
+running at a particular frequency, CPR monitors dynamic factors such as
+temperature, etc. and suggests adjustments to the voltage to save power
+and meet silicon characteristic requirements.

- datasheet
-- interrupts: Should contain one interrupt specifier for the GPC interrupt
-- clocks: Must contain an entry for each entry in clock-names.
- See Documentation/devicetree/bindings/clock/clock-bindings.txt for details.
-- clock-names: Must include the following entries:
- - ipg
-
-The power domains are generic power domain providers as documented in
-Documentation/devicetree/bindings/power/power_domain.txt. They are described as
-subnodes of the power gating controller 'pgc' node of the GPC and should
-contain the following:
-
-Required properties:
-- reg: Must contain the DOMAIN_INDEX of this power domain
- The following DOMAIN_INDEX values are valid for i.MX6Q:
- ARM_DOMAIN 0
- PU_DOMAIN 1
- The following additional DOMAIN_INDEX value is valid for i.MX6SL:
- DISPLAY_DOMAIN 2
- The following additional DOMAIN_INDEX value is valid for i.MX6SX:

+description: |+
+ System on chip designs are often divided into multiple PM domains that can be
+ used for power gating of selected IP blocks for power saving by reduced leakage
+ current.
+
+ This device tree binding can be used to bind PM domain consumer devices with
+ their PM domains provided by PM domain providers. A PM domain provider can be
+ represented by any node in the device tree and can provide one or more PM
+ domains. A consumer node can refer to the provider by a phandle and a set of
+ phandle arguments (so called PM domain specifiers) of length specified by the
+ \#power-domain-cells property in the PM domain provider node.

+ domain-idle-state bindings, specified in ./domain-idle-state.yaml.
+
+ Note that, the domain-idle-state property reflects the idle states of this
+ PM domain and not the idle states of the devices or sub-domains in the PM
+ domain. Devices and sub-domains have their own idle states independent of
+ the parent domain's idle states. In the absence of this property, the
+ domain would be considered as capable of being powered-on or powered-off.

==PM domain providers==
-Required properties:
- - #power-domain-cells : Number of cells in a PM domain specifier;
- Typically 0 for nodes representing a single PM domain and 1 for nodes
- providing multiple PM domains (e.g. power controllers), but can be any value
- as specified by device tree binding documentation of particular provider.
-
-Optional properties:
- - power-domains : A phandle and PM domain specifier as defined by bindings of
- the power controller specified by phandle.
- Some power domains might be powered from another power domain (or have
- other hardware specific dependencies). For representing such dependency
- a standard PM domain consumer binding is used. When provided, all domains
- created by the given provider should be subdomains of the domain
- specified by this binding. More details about power domain specifier are
- available in the next section.
-
-- domain-idle-states : A phandle of an idle-state that shall be soaked into a
- generic domain power state. The idle state definitions are
- compatible with domain-idle-state specified in [1]. phandles
- that are not compatible with domain-idle-state will be
- ignored.
- The domain-idle-state property reflects the idle state of this PM domain and
- not the idle states of the devices or sub-domains in the PM domain. Devices
- and sub-domains have their own idle-states independent of the parent
- domain's idle states. In the absence of this property, the domain would be
- considered as capable of being powered-on or powered-off.
-
-- operating-points-v2 : Phandles to the OPP tables of power domains provided by
- a power domain provider. If the provider provides a single power domain only
- or all the power domains provided by the provider have identical OPP tables,
- then this shall contain a single phandle. Refer to ../opp/opp.txt for more
- information.
-
-Example:
-
- power: power-controller@12340000 {
- compatible = "foo,power-controller";
- reg = <0x12340000 0x1000>;
- #power-domain-cells = <1>;
- };
-
-The node above defines a power controller that is a PM domain provider and
-expects one cell as its phandle argument.
-
-Example 2:
-
- parent: power-controller@12340000 {
- compatible = "foo,power-controller";
- reg = <0x12340000 0x1000>;
- #power-domain-cells = <1>;
- };
-
- child: power-controller@12341000 {
- compatible = "foo,power-controller";
- reg = <0x12341000 0x1000>;
- power-domains = <&parent 0>;
- #power-domain-cells = <1>;
- };
-
-The nodes above define two power controllers: 'parent' and 'child'.
-Domains created by the 'child' power controller are subdomains of '0' power
-domain provided by the 'parent' power controller.
-
-Example 3:
- parent: power-controller@12340000 {
- compatible = "foo,power-controller";
- reg = <0x12340000 0x1000>;

+
+description: |
+ Devices on SOCs often have mechanisms for placing devices into low-power
+ states that are decoupled from the devices' own register blocks. Sometimes,
+ this information is more complicated than a cell-index property can
+ reasonably describe. Thus, each device controlled in such a manner
+ may contain a "sleep" property which describes these connections.
+
+ The sleep property consists of one or more sleep resources, each of
+ which consists of a phandle to a sleep controller, followed by a
+ controller-specific sleep specifier of zero or more cells.
+
+ The semantics of what type of low power modes are possible are defined
+ by the sleep controller. Some examples of the types of low power modes
+ that may be supported are:
+
+ - Dynamic: The device may be disabled or enabled at any time.
+ - System Suspend: The device may request to be disabled or remain
+ awake during system suspend, but will not be disabled until then.
+ - Permanent: The device is disabled permanently (until the next hard
+ reset).
+
+ Some devices may share a clock domain with each other, such that they should
+ only be suspended when none of the devices are in use. Where reasonable,
+ such nodes should be placed on a virtual bus, where the bus has the sleep
+ property. If the clock domain is shared among devices that cannot be
+ reasonably grouped in this manner, then create a virtual sleep controller
+ (similar to an interrupt nexus, except that defining a standardized
+ sleep-map should wait until its necessity is demonstrated).

+ZHAW InES PTP time stamping IP core
+
+The IP core needs two different kinds of nodes. The control node
+lives somewhere in the memory map and specifies the address of the
+control registers. There can be up to three port handles placed as
+attributes of PHY nodes. These associate a particular MII bus with a
+port index within the IP core.
+
+Required properties of the control node:
+
+- compatible: "ines,ptp-ctrl"
+- reg: physical address and size of the register bank
+
+Required format of the port handle within the PHY node:
+
+- timestamper: provides control node reference and
+ the port channel within the IP core
+
+Example:
+
+ tstamper: timestamper@60000000 {
+ compatible = "ines,ptp-ctrl";
+ reg = <0x60000000 0x80>;
+ };

+Time stamps from MII bus snooping devices
+
+This binding supports non-PHY devices that snoop the MII bus and
+provide time stamps. In contrast to PHY time stamping drivers (which
+can simply attach their interface directly to the PHY instance), stand
+alone MII time stamping drivers use this binding to specify the
+connection between the snooping device and a given network interface.
+
+Non-PHY MII time stamping drivers typically talk to the control
+interface over another bus like I2C, SPI, UART, or via a memory mapped
+peripheral. This controller device is associated with one or more
+time stamping channels, each of which snoops on a MII bus.
+
+The "timestamper" property lives in a phy node and links a time
+stamping channel from the controller device to that phy's MII bus.
+
+Example:
+
+ tstamper: timestamper@10000000 {
+ compatible = "ines,ptp-ctrl";
+ reg = <0x10000000 0x80>;
+ };
+
+ ethernet@20000000 {
+ mdio {
+ ethernet-phy@1 {
+ timestamper = <&tstamper 0>;
+ };
+ };
+ };
+
+ ethernet@30000000 {
+ mdio {
+ ethernet-phy@2 {
+ timestamper = <&tstamper 1>;
+ };
+ };
+ };
+
+In this example, time stamps from the MII bus attached to phy@1 will
+appear on time stamp channel 0 (zero), and those from phy@2 appear on
+channel 1.

-SiFive PWM controller
-
-Unlike most other PWM controllers, the SiFive PWM controller currently only
-supports one period for all channels in the PWM. All PWMs need to run at
-the same period. The period also has significant restrictions on the values
-it can achieve, which the driver rounds to the nearest achievable period.
-PWM RTL that corresponds to the IP block version numbers can be found
-here:
-
-https://github.com/sifive/sifive-blocks/tree/master/src/main/scala/devices/pwm
-
-Required properties:
-- compatible: Should be "sifive,<chip>-pwm" and "sifive,pwm<version>".
- Supported compatible strings are: "sifive,fu540-c000-pwm" for the SiFive
- PWM v0 as integrated onto the SiFive FU540 chip, and "sifive,pwm0" for the
- SiFive PWM v0 IP block with no chip integration tweaks.
- Please refer to sifive-blocks-ip-versioning.txt for details.
-- reg: physical base address and length of the controller's registers

+ Unlike most other PWM controllers, the SiFive PWM controller currently
+ only supports one period for all channels in the PWM. All PWMs need to
+ run at the same period. The period also has significant restrictions on
+ the values it can achieve, which the driver rounds to the nearest
+ achievable period. PWM RTL that corresponds to the IP block version
+ numbers can be found here -

-Cirrus Logic Lochnagar Audio Development Board
-
-Lochnagar is an evaluation and development board for Cirrus Logic
-Smart CODEC and Amp devices. It allows the connection of most Cirrus
-Logic devices on mini-cards, as well as allowing connection of
-various application processor systems to provide a full evaluation
-platform. Audio system topology, clocking and power can all be
-controlled through the Lochnagar, allowing the device under test
-to be used in a variety of possible use cases.
-
-This binding document describes the binding for the regulator portion
-of the driver.
-
-Also see these documents for generic binding information:

+NVIDIA Tegra Regulators Coupling
+================================
+
+NVIDIA Tegra SoC's have a mandatory voltage-coupling between regulators.
+Thus on Tegra20 there are 3 coupled regulators and on NVIDIA Tegra30
+there are 2.
+
+Tegra20 voltage coupling
+------------------------
+
+On Tegra20 SoC's there are 3 coupled regulators: CORE, RTC and CPU.
+The CORE and RTC voltages shall be in a range of 170mV from each other
+and they both shall be higher than the CPU voltage by at least 120mV.
+
+Tegra30 voltage coupling
+------------------------
+
+On Tegra30 SoC's there are 2 coupled regulators: CORE and CPU. The CORE
+and CPU voltages shall be in a range of 300mV from each other and CORE
+voltage shall be higher than the CPU by N mV, where N depends on the CPU
+voltage.
+
+Required properties:
+- nvidia,tegra-core-regulator: Boolean property that designates regulator
+ as the "Core domain" voltage regulator.
+- nvidia,tegra-rtc-regulator: Boolean property that designates regulator
+ as the "RTC domain" voltage regulator.
+- nvidia,tegra-cpu-regulator: Boolean property that designates regulator
+ as the "CPU domain" voltage regulator.
+
+Example:
+
+ pmic {
+ regulators {
+ core_vdd_reg: core {
+ regulator-name = "vdd_core";
+ regulator-min-microvolt = <950000>;
+ regulator-max-microvolt = <1300000>;
+ regulator-coupled-with = <&rtc_vdd_reg &cpu_vdd_reg>;
+ regulator-coupled-max-spread = <170000 550000>;
+
+ nvidia,tegra-core-regulator;
+ };
+
+ rtc_vdd_reg: rtc {
+ regulator-name = "vdd_rtc";
+ regulator-min-microvolt = <950000>;
+ regulator-max-microvolt = <1300000>;

-PFUZE100 family of regulators
-
-Required properties:
-- compatible: "fsl,pfuze100", "fsl,pfuze200", "fsl,pfuze3000", "fsl,pfuze3001"
-- reg: I2C slave address
-
-Optional properties:
-- fsl,pfuze-support-disable-sw: Boolean, if present disable all unused switch
- regulators to save power consumption. Attention, ensure that all important
- regulators (e.g. DDR ref, DDR supply) has set the "regulator-always-on"
- property. If not present, the switched regulators are always on and can't be
- disabled. This binding is a workaround to keep backward compatibility with
- old dtb's which rely on the fact that the switched regulators are always on
- and don't mark them explicit as "regulator-always-on".
-- fsl,pmic-stby-poweroff: if present, configure the PMIC to shutdown all
- power rails when PMIC_STBY_REQ line is asserted during the power off sequence.
- Use this option if the SoC should be powered off by external power
- management IC (PMIC) on PMIC_STBY_REQ signal.
- As opposite to PMIC_STBY_REQ boards can implement PMIC_ON_REQ signal.
-
-Required child node:
-- regulators: This is the list of child nodes that specify the regulator
- initialization data for defined regulators. Please refer to below doc
- Documentation/devicetree/bindings/regulator/regulator.txt.
-
- The valid names for regulators are:

-QCOM SMD RPM REGULATOR
-
-The Qualcomm RPM over SMD regulator is modelled as a subdevice of the RPM.
-Because SMD is used as the communication transport mechanism, the RPM resides as
-a subnode of the SMD. As such, the SMD-RPM regulator requires that the SMD and
-RPM nodes be present.
-
-Please refer to Documentation/devicetree/bindings/soc/qcom/qcom,smd.txt for
-information pertaining to the SMD node.

+title: QCOM SMD RPM REGULATOR
+
+description:
+ The Qualcomm RPM over SMD regulator is modelled as a subdevice of the RPM.
+ Because SMD is used as the communication transport mechanism, the RPM
+ resides as a subnode of the SMD. As such, the SMD-RPM regulator requires
+ that the SMD and RPM nodes be present.
+
+ Please refer to Documentation/devicetree/bindings/soc/qcom/qcom,smd.txt for
+ information pertaining to the SMD node.
+
+ Please refer to Documentation/devicetree/bindings/soc/qcom/qcom,smd-rpm.yaml
+ for information regarding the RPM node.
+
+ The regulator node houses sub-nodes for each regulator within the device.

+ for each of the pmics below.

+ should be sub node of the BD71847 MFD node. See BD71847 MFD bindings at
+ Documentation/devicetree/bindings/mfd/rohm,bd71847-pmic.yaml

+ voltage monitoring for LDO5/LDO6 can cause PMIC to reset.

-STMicroelectronics STPMIC1 Voltage regulators
-
-Regulator Nodes are optional depending on needs.
-
-Available Regulators in STPMIC1 device are:
- - buck1 for Buck BUCK1
- - buck2 for Buck BUCK2
- - buck3 for Buck BUCK3
- - buck4 for Buck BUCK4
- - ldo1 for LDO LDO1
- - ldo2 for LDO LDO2
- - ldo3 for LDO LDO3
- - ldo4 for LDO LDO4
- - ldo5 for LDO LDO5
- - ldo6 for LDO LDO6
- - vref_ddr for LDO Vref DDR
- - boost for Buck BOOST
- - pwr_sw1 for VBUS_OTG switch
- - pwr_sw2 for SW_OUT switch
-
-Switches are fixed voltage regulators with only enable/disable capability.
-
-Optional properties:
-- st,mask-reset: mask reset for this regulator: the regulator configuration
- is maintained during pmic reset.
-- regulator-over-current-protection:
- if set, all regulators are switched off in case of over-current detection
- on this regulator,
- if not set, the driver only sends an over-current event.
-- interrupts: index of current limit detection interrupt
-- <regulator>-supply: phandle to the parent supply/regulator node
- each regulator supply can be described except vref_ddr.
-- regulator-active-discharge: can be used on pwr_sw1 and pwr_sw2.
-
-Example:

+Mediatek SCP Bindings
+----------------------------------------
+
+This binding provides support for ARM Cortex M4 Co-processor found on some
+Mediatek SoCs.
+
+Required properties:
+- compatible Should be "mediatek,mt8183-scp"
+- reg Should contain the address ranges for the two memory
+ regions, SRAM and CFG.
+- reg-names Contains the corresponding names for the two memory
+ regions. These should be named "sram" & "cfg".
+- clocks Clock for co-processor (See: ../clock/clock-bindings.txt)
+- clock-names Contains the corresponding name for the clock. This
+ should be named "main".
+
+Subnodes
+--------
+
+Subnodes of the SCP represent rpmsg devices. The names of the devices are not
+important. The properties of these nodes are defined by the individual bindings
+for the rpmsg devices - but must contain the following property:
+
+- mtk,rpmsg-name Contains the name for the rpmsg device. Used to match
+ the subnode to rpmsg device announced by SCP.
+
+Example:
+
+ scp: scp@10500000 {
+ compatible = "mediatek,mt8183-scp";
+ reg = <0 0x10500000 0 0x80000>,

+ The TI K3 family of SoCs usually have one or more dual-core Arm Cortex R5F
+ processor subsystems/clusters (R5FSS). The dual core cluster can be used
+ either in a LockStep mode providing safety/fault tolerance features or in a

+ capacity. These are used together with other processors present on the SoC
+ to achieve various system level goals.
+
+ Each Dual-Core R5F sub-system is represented as a single DTS node
+ representing the cluster, with a pair of child DT nodes representing

+
+ Each R5F core has an associated 64 KB of Tightly-Coupled Memory (TCM)

-Required properties:
-- compatible: can be one of the following:
- - "st,stm32-rtc" for devices compatible with stm32(f4/f7).
- - "st,stm32h7-rtc" for devices compatible with stm32h7.
- - "st,stm32mp1-rtc" for devices compatible with stm32mp1.
-- reg: address range of rtc register set.
-- clocks: can use up to two clocks, depending on part used:
- - "rtc_ck": RTC clock source.
- - "pclk": RTC APB interface clock.
- It is not present on stm32(f4/f7).
- It is required on stm32(h7/mp1).
-- clock-names: must be "rtc_ck" and "pclk".
- It is required on stm32(h7/mp1).
-- interrupts: rtc alarm interrupt. On stm32mp1, a second interrupt is required
- for rtc alarm wakeup interrupt.
-- st,syscfg: phandle/offset/mask triplet. The phandle to pwrcfg used to
- access control register at offset, and change the dbp (Disable Backup
- Protection) bit represented by the mask, mandatory to disable/enable backup
- domain (RTC registers) write protection.
- It is required on stm32(f4/f7/h7).
-
-Optional properties (to override default rtc_ck parent clock on stm32(f4/f7/h7):
-- assigned-clocks: reference to the rtc_ck clock entry.
-- assigned-clock-parents: phandle of the new parent clock of rtc_ck.

-- reg : offset and length of the register set for the device.
-- interrupts : should contain uart interrupt.
-- clock-frequency : the input clock frequency for the UART
- or
- clocks phandle to refer to the clk used as per Documentation/devicetree
- /bindings/clock/clock-bindings.txt
-
-Optional properties:
-- current-speed : the current active speed of the UART.
-- reg-offset : offset to apply to the mapbase from the start of the registers.
-- reg-shift : quantity to shift the register offsets by.
-- reg-io-width : the size (in bytes) of the IO accesses that should be
- performed on the device. There are some systems that require 32-bit
- accesses to the UART (e.g. TI davinci).
-- used-by-rtas : set to indicate that the port is in use by the OpenFirmware
- RTAS and should not be registered.
-- no-loopback-test: set to indicate that the port does not implements loopback
- test mode
-- fifo-size: the fifo size of the UART.
-- auto-flow-control: one way to enable automatic flow control support. The
- driver is allowed to detect support for the capability even without this
- property.
-- tx-threshold: Specify the TX FIFO low water indication for parts with
- programmable TX FIFO thresholds.
-- resets : phandle + reset specifier pairs
-- overrun-throttle-ms : how long to pause uart rx when input overrun is encountered.
-- {rts,cts,dtr,dsr,rng,dcd}-gpios: specify a GPIO for RTS/CTS/DTR/DSR/RI/DCD
- line respectively. It will use specified GPIO instead of the peripheral
- function pin for the UART feature. If unsure, don't specify this property.
-
-Note:
-* fsl,ns16550:
- ------------
- Freescale DUART is very similar to the PC16552D (and to a
- pair of NS16550A), albeit with some nonstandard behavior such as
- erratum A-004737 (relating to incorrect BRK handling).
-
- Represents a single port that is compatible with the DUART found
- on many Freescale chips (examples include mpc8349, mpc8548,
- mpc8641d, p4080 and ls2085a).
-
-Example:
-
- uart@80230000 {
- compatible = "ns8250";
- reg = <0x80230000 0x100>;
- clock-frequency = <3686400>;
- interrupts = <10>;
- reg-shift = <2>;
- };
-
-Example for OMAP UART using GPIO-based modem control signals:
-
- uart4: serial@49042000 {
- compatible = "ti,omap3-uart";
- reg = <0x49042000 0x400>;

- - "fsl,vf610-lpuart" for lpuart compatible with the one integrated
- on Vybrid vf610 SoC with 8-bit register organization
- - "fsl,ls1021a-lpuart" for lpuart compatible with the one integrated
- on LS1021A SoC with 32-bit big-endian register organization
- - "fsl,imx7ulp-lpuart" for lpuart compatible with the one integrated
- on i.MX7ULP SoC with 32-bit little-endian register organization
- - "fsl,imx8qxp-lpuart" for lpuart compatible with the one integrated

-- reg : Address and length of the register set for the device
-- interrupts : Should contain uart interrupt
-- clocks : phandle + clock specifier pairs, one for each entry in clock-names
-- clock-names : For vf610/ls1021a/imx7ulp, "ipg" clock is for uart bus/baud
- clock. For imx8qxp lpuart, "ipg" clock is bus clock that is used to access
- lpuart controller registers, it also requires "baud" clock for module to
- receive/transmit data.
-
-Optional properties:
-- dmas: A list of two dma specifiers, one for each entry in dma-names.
-- dma-names: should contain "tx" and "rx".

-* Freescale MXS Application UART (AUART)
-
-Required properties for all SoCs:
-- compatible : Should be one of fallowing variants:
- "fsl,imx23-auart" - Freescale i.MX23
- "fsl,imx28-auart" - Freescale i.MX28
- "alphascale,asm9260-auart" - Alphascale ASM9260
-- reg : Address and length of the register set for the device
-- interrupts : Should contain the auart interrupt numbers
-- dmas: DMA specifier, consisting of a phandle to DMA controller node
- and AUART DMA channel ID.
- Refer to dma.txt and fsl-mxs-dma.txt for details.
-- dma-names: "rx" for RX channel, "tx" for TX channel.
-
-Required properties for "alphascale,asm9260-auart":
-- clocks : the clocks feeding the watchdog timer. See clock-bindings.txt
-- clock-names : should be set to
- "mod" - source for tick counter.
- "ahb" - ahb gate.
-
-Optional properties:
-- uart-has-rtscts : Indicate the UART has RTS and CTS lines
- for hardware flow control,
- it also means you enable the DMA support for this UART.
-- {rts,cts,dtr,dsr,rng,dcd}-gpios: specify a GPIO for RTS/CTS/DTR/DSR/RI/DCD
- line respectively. It will use specified PIO instead of the peripheral
- function pin for the USART feature.
- If unsure, don't specify this property.
-
-Example:
-auart0: serial@8006a000 {
- compatible = "fsl,imx28-auart", "fsl,imx23-auart";
- reg = <0x8006a000 0x2000>;
- interrupts = <112>;
- dmas = <&dma_apbx 8>, <&dma_apbx 9>;
- dma-names = "rx", "tx";
- cts-gpios = <&gpio1 15 GPIO_ACTIVE_LOW>;
- dsr-gpios = <&gpio1 16 GPIO_ACTIVE_LOW>;
- dcd-gpios = <&gpio1 17 GPIO_ACTIVE_LOW>;
-};
-
-Note: Each auart port should have an alias correctly numbered in "aliases"
-node.
-
-Example:
-
-aliases {
- serial0 = &auart0;
- serial1 = &auart1;
- serial2 = &auart2;
- serial3 = &auart3;
- serial4 = &auart4;

-
- When compatible with the generic version, nodes must list the
- SoC-specific version corresponding to the platform first, followed by the
- family-specific and/or generic versions.
-
- - reg: Base address and length of the I/O registers used by the UART.
- - interrupts: Must contain one or more interrupt-specifiers for the SCIx.
- If a single interrupt is expressed, then all events are
- multiplexed into this single interrupt.
-
- If multiple interrupts are provided by the hardware, the order
- in which the interrupts are listed must match order below. Note
- that some HW interrupt events may be muxed together resulting
- in duplicate entries.
- The interrupt order is as follows:
- 1. Error (ERI)
- 2. Receive buffer full (RXI)
- 3. Transmit buffer empty (TXI)
- 4. Break (BRI)
- 5. Data Ready (DRI)
- 6. Transmit End (TEI)
-
- - clocks: Must contain a phandle and clock-specifier pair for each entry
- in clock-names.
- - clock-names: Must contain "fck" for the SCIx UART functional clock.
- Apart from the divided functional clock, there may be other possible
- sources for the sampling clock, depending on SCIx variant.
- On (H)SCI(F) and some SCIFA, an additional clock may be specified:
- - "hsck" for the optional external clock input (on HSCIF),
- - "sck" for the optional external clock input (on other variants).
- On UARTs equipped with a Baud Rate Generator for External Clock (BRG)
- (some SCIF and HSCIF), additional clocks may be specified:
- - "brg_int" for the optional internal clock source for the frequency
- divider (typically the (AXI or SHwy) bus clock),
- - "scif_clk" for the optional external clock source for the frequency
- divider (SCIF_CLK).
-
-Note: Each enabled SCIx UART may have an optional "serialN" alias in the
-"aliases" node.
-
-Optional properties:
- - dmas: Must contain a list of two references to DMA specifiers, one for
- transmission, and one for reception.
- - dma-names: Must contain a list of two DMA names, "tx" and "rx".
- - {cts,dsr,dcd,rng,rts,dtr}-gpios: Specify GPIOs for modem lines, cfr. the
- generic serial DT bindings in serial.txt.
- - uart-has-rtscts: Indicates dedicated lines for RTS/CTS hardware flow
- control, cfr. the generic serial DT bindings in serial.txt.
-
-Example:
- aliases {
- serial0 = &scifa0;
- };
-
- scifa0: serial@e6c40000 {
- compatible = "renesas,scifa-r8a7790",
- "renesas,rcar-gen2-scifa", "renesas,scifa";

-Generic Serial DT Bindings
-
-This document lists a set of generic properties for describing UARTs in a
-device tree. Whether these properties apply to a particular device depends on
-the DT bindings for the actual device.
-
-Optional properties:
- - cts-gpios: Must contain a GPIO specifier, referring to the GPIO pin to be
- used as the UART's CTS line.
- - dcd-gpios: Must contain a GPIO specifier, referring to the GPIO pin to be
- used as the UART's DCD line.
- - dsr-gpios: Must contain a GPIO specifier, referring to the GPIO pin to be
- used as the UART's DSR line.
- - dtr-gpios: Must contain a GPIO specifier, referring to the GPIO pin to be
- used as the UART's DTR line.
- - rng-gpios: Must contain a GPIO specifier, referring to the GPIO pin to be
- used as the UART's RNG line.
- - rts-gpios: Must contain a GPIO specifier, referring to the GPIO pin to be
- used as the UART's RTS line.
-
- - uart-has-rtscts: The presence of this property indicates that the
- UART has dedicated lines for RTS/CTS hardware flow control, and that
- they are available for use (wired and enabled by pinmux configuration).
- This depends on both the UART hardware and the board wiring.
- Note that this property is mutually-exclusive with "cts-gpios" and
- "rts-gpios" above, unless support is provided to switch between modes
- dynamically.
-
-
-Examples:
-
- uart1: serial@48022000 {
- compatible = "ti,am3352-uart", "ti,omap3-uart";
- ti,hwmods = "uart2";
- clock-frequency = <48000000>;
- reg = <0x48022000 0x2000>;
- interrupts = <73>;
- dmas = <&edma 28 0>, <&edma 29 0>;

- };

-Amlogic Canvas
-================================
-
-A canvas is a collection of metadata that describes a pixel buffer.
-Those metadata include: width, height, phyaddr, wrapping and block mode.
-Starting with GXBB the endianness can also be described.
-
-Many IPs within Amlogic SoCs rely on canvas indexes to read/write pixel data
-rather than use the phy addresses directly. For instance, this is the case for
-the video decoders and the display.
-
-Amlogic SoCs have 256 canvas.
-
-Device Tree Bindings:
----------------------
-
-Video Lookup Table
---------------------------
-
-Required properties:
-- compatible: has to be one of:
- - "amlogic,meson8-canvas", "amlogic,canvas" on Meson8
- - "amlogic,meson8b-canvas", "amlogic,canvas" on Meson8b
- - "amlogic,meson8m2-canvas", "amlogic,canvas" on Meson8m2
- - "amlogic,canvas" on GXBB and newer
-- reg: Base physical address and size of the canvas registers.

- compatible = "amlogic,canvas";
- reg = <0x0 0x48 0x0 0x14>;

+ The Ring Accelerator (RA) is a machine which converts read/write accesses
+ from/to a constant address into corresponding read/write accesses from/to a
+ circular data structure in memory. The RA eliminates the need for each DMA
+ controller which needs to access ring elements from having to know the current
+ state of the ring (base address, current offset). The DMA controller
+ performs a read or write access to a specific address range (which maps to the
+ source interface on the RA) and the RA replaces the address for the transaction
+ with a new address which corresponds to the head or tail element of the ring
+ (head for reads, tail for writes).
+
+ The Ring Accelerator is a hardware module that is responsible for accelerating
+ management of the packet queues. The K3 SoCs can have more than one RA instances

+ TI Programmable Real-Time Unit and Industrial Communication Subsystem

+
+description: |+
+
+ The Programmable Real-Time Unit and Industrial Communication Subsystem
+ (PRU-ICSS a.k.a. PRUSS) is present on various TI SoCs such as AM335x, AM437x,
+ Keystone 66AK2G, OMAP-L138/DA850 etc. A PRUSS consists of dual 32-bit RISC
+ cores (Programmable Real-Time Units, or PRUs), shared RAM, data and
+ instruction RAMs, some internal peripheral modules to facilitate industrial
+ communication, and an interrupt controller.
+
+ The programmable nature of the PRUs provide flexibility to implement custom
+ peripheral interfaces, fast real-time responses, or specialized data handling.
+ The common peripheral modules include the following,
+ - an Ethernet MII_RT module with two MII ports
+ - an MDIO port to control external Ethernet PHYs
+ - an Industrial Ethernet Peripheral (IEP) to manage/generate Industrial
+ Ethernet functions
+ - an Enhanced Capture Module (eCAP)
+ - an Industrial Ethernet Timer with 7/9 capture and 16 compare events
+ - a 16550-compatible UART to support PROFIBUS
+ - Enhanced GPIO with async capture and serial support
+
+ A PRU-ICSS subsystem can have up to three shared data memories. A PRU core
+ acts on a primary Data RAM (there are usually 2 Data RAMs) at its address
+ 0x0, but also has access to a secondary Data RAM (primary to the other PRU
+ core) at its address 0x2000. A shared Data RAM, if present, can be accessed
+ by both the PRU cores. The Interrupt Controller (INTC) and a CFG module are
+ common to both the PRU cores. Each PRU core also has a private instruction
+ RAM, and specific register spaces for Control and Debug functionalities.
+
+ Various sub-modules within a PRU-ICSS subsystem are represented as individual
+ nodes and are defined using a parent-child hierarchy depending on their
+ integration within the IP and the SoC. These nodes are described in the
+ following sections.
+
+
+ PRU-ICSS Node
+ ==============
+ Each PRU-ICSS instance is represented as its own node with the individual PRU
+ processor cores, the memories node, an INTC node and an MDIO node represented
+ as child nodes within this PRUSS node. This node shall be a child of the
+ corresponding interconnect bus nodes or target-module nodes.
+
+ See ../../mfd/syscon.yaml for generic SysCon binding details.

+description:
+ The CS4234 is a highly versatile CODEC that combines 4 channels of
+ high performance analog to digital conversion, 4 channels of high
+ performance digital to analog conversion for audio, and 1 channel of
+ digital to analog conversion to provide a nondelayed audio reference
+ signal to an external Class H tracking power supply. If not used to
+ drive a tracking power supply, the 5th DAC can instead be used as a
+ standard audio grade DAC, with performance specifications identical
+ to that of the 4 DACs in the audio path. Additionally, the CS4234
+ includes tunable group delay for each of the 4 audio DAC paths to
+ provide lead time for the external switch-mode power supply, and a
+ nondelayed path into the DAC outputs for input signals requiring a
+ low-latency path to the outputs.

-Lochnagar is an evaluation and development board for Cirrus Logic
-Smart CODEC and Amp devices. It allows the connection of most Cirrus
-Logic devices on mini-cards, as well as allowing connection of
-various application processor systems to provide a full evaluation
-platform. Audio system topology, clocking and power can all be
-controlled through the Lochnagar, allowing the device under test
-to be used in a variety of possible use cases.
-
-This binding document describes the binding for the audio portion
-of the driver.
-
-This binding must be part of the Lochnagar MFD binding:
- [4] ../mfd/cirrus,lochnagar.txt
-
-Required properties:

-This describes audio configuration bindings for these codecs.
-
-See also the core bindings for the parent MFD driver:
-See Documentation/devicetree/bindings/mfd/madera.txt
-
-and defines for values used in these bindings:
-include/dt-bindings/sound/madera.h
-
-These properties are all contained in the parent MFD node.
-
-Optional properties:
- - cirrus,dmic-ref : Indicates how the MICBIAS pins have been externally
- connected to DMICs on each input, one cell per input.
- <IN1 IN2 IN3 ...>
- A value of 0 indicates MICVDD and is the default, other values depend on the
- codec:
- For CS47L35 one of the CS47L35_DMIC_REF_xxx values
- For all other codecs one of the MADERA_DMIC_REF_xxx values
- Also see the datasheet for a description of the INn_DMIC_SUP field.
-
- - cirrus,inmode : A list of input mode settings for each input. A maximum of
- 16 cells, with four cells per input in the order INnAL, INnAR INnBL INnBR.
- For non-muxed inputs the first two cells for that input set the mode for
- the left and right channel and the second two cells must be 0.
- For muxed inputs the first two cells for that input set the mode of the
- left and right A inputs and the second two cells set the mode of the left
- and right B inputs.
- Valid mode values are one of the MADERA_INMODE_xxx. If the array is shorter
- than the number of inputs the unspecified inputs default to
- MADERA_INMODE_DIFF.
-
- - cirrus,out-mono : Mono bit for each output, maximum of six cells if the
- array is shorter outputs will be set to stereo.
-
- - cirrus,max-channels-clocked : Maximum number of channels that I2S clocks
- will be generated for. Useful when clock master for systems where the I2S
- bus has multiple data lines.
- One cell for each AIF, use a value of zero for AIFs that should be handled
- normally.
-
- - cirrus,pdm-fmt : PDM speaker data format, must contain 2 cells
- (OUT5 and OUT6). See the PDM_SPKn_FMT field in the datasheet for a
- description of this value.
- The second cell is ignored for codecs that do not have OUT6.
-
- - cirrus,pdm-mute : PDM mute format, must contain 2 cells
- (OUT5 and OUT6). See the PDM_SPKn_CTRL_1 register in the datasheet for a
- description of this value.
- The second cell is ignored for codecs that do not have OUT6.
-
-Example:
-

-* Samsung I2S controller
-
-Required SoC Specific Properties:
-
-- compatible : should be one of the following.
- - samsung,s3c6410-i2s: for 8/16/24bit stereo I2S.
- - samsung,s5pv210-i2s: for 8/16/24bit multichannel(5.1) I2S with
- secondary fifo, s/w reset control and internal mux for root clk src.
- - samsung,exynos5420-i2s: for 8/16/24bit multichannel(5.1) I2S for
- playback, stereo channel capture, secondary fifo using internal
- or external dma, s/w reset control, internal mux for root clk src
- and 7.1 channel TDM support for playback. TDM (Time division multiplexing)
- is to allow transfer of multiple channel audio data on single data line.
- - samsung,exynos7-i2s: with all the available features of exynos5 i2s,
- exynos7 I2S has 7.1 channel TDM support for capture, secondary fifo
- with only external dma and more no.of root clk sampling frequencies.
- - samsung,exynos7-i2s1: I2S1 on previous samsung platforms supports
- stereo channels. exynos7 i2s1 upgraded to 5.1 multichannel with
- slightly modified bit offsets.
-
-- reg: physical base address of the controller and length of memory mapped
- region.
-- dmas: list of DMA controller phandle and DMA request line ordered pairs.
-- dma-names: identifier string for each DMA request line in the dmas property.
- These strings correspond 1:1 with the ordered pairs in dmas.
-- clocks: Handle to iis clock and RCLK source clk.
-- clock-names:
- i2s0 uses some base clocks from CMU and some are from audio subsystem internal
- clock controller. The clock names for i2s0 should be "iis", "i2s_opclk0" and
- "i2s_opclk1" as shown in the example below.
- i2s1 and i2s2 uses clocks from CMU. The clock names for i2s1 and i2s2 should
- be "iis" and "i2s_opclk0".
- "iis" is the i2s bus clock and i2s_opclk0, i2s_opclk1 are sources of the root
- clk. i2s0 has internal mux to select the source of root clk and i2s1 and i2s2
- doesn't have any such mux.
-- #clock-cells: should be 1, this property must be present if the I2S device
- is a clock provider in terms of the common clock bindings, described in
- ../clock/clock-bindings.txt.
-- clock-output-names (deprecated): from the common clock bindings, names of
- the CDCLK I2S output clocks, suggested values are "i2s_cdclk0", "i2s_cdclk1",
- "i2s_cdclk3" for the I2S0, I2S1, I2S2 devices respectively.
-
-There are following clocks available at the I2S device nodes:
- CLK_I2S_CDCLK - the CDCLK (CODECLKO) gate clock,
- CLK_I2S_RCLK_PSR - the RCLK prescaler divider clock (corresponding to the
- IISPSR register),
- CLK_I2S_RCLK_SRC - the RCLKSRC mux clock (corresponding to RCLKSRC bit in
- IISMOD register).
-
-Refer to the SoC datasheet for availability of the above clocks.
-The CLK_I2S_RCLK_PSR and CLK_I2S_RCLK_SRC clocks are usually only available
-in the IIS Multi Audio Interface.
-
-Note: Old DTs may not have the #clock-cells property and then not use the I2S
-node as a clock supplier.
-
-Optional SoC Specific Properties:
-
-- samsung,idma-addr: Internal DMA register base address of the audio
- sub system(used in secondary sound source).
-- pinctrl-0: Should specify pin control groups used for this controller.
-- pinctrl-names: Should contain only one value - "default".
-- #sound-dai-cells: should be 1.
-
-
-Example:
-
-i2s0: i2s@3830000 {

-Simple-Card:
-
-Simple-Card specifies audio DAI connections of SoC <-> codec.
-
-Required properties:
-
-- compatible : "simple-audio-card"
-
-Optional properties:
-
-- simple-audio-card,name : User specified audio sound card name, one string
- property.
-- simple-audio-card,widgets : Please refer to widgets.txt.
-- simple-audio-card,routing : A list of the connections between audio components.
- Each entry is a pair of strings, the first being the
- connection's sink, the second being the connection's
- source.
-- simple-audio-card,mclk-fs : Multiplication factor between stream rate and codec
- mclk. When defined, mclk-fs property defined in
- dai-link sub nodes are ignored.
-- simple-audio-card,hp-det-gpio : Reference to GPIO that signals when
- headphones are attached.
-- simple-audio-card,mic-det-gpio : Reference to GPIO that signals when
- a microphone is attached.
-- simple-audio-card,aux-devs : List of phandles pointing to auxiliary devices, such
- as amplifiers, to be added to the sound card.
-- simple-audio-card,pin-switches : List of strings containing the widget names for
- which pin switches must be created.
-
-Optional subnodes:
-
-- simple-audio-card,dai-link : Container for dai-link level
- properties and the CPU and CODEC
- sub-nodes. This container may be
- omitted when the card has only one
- DAI link. See the examples and the
- section below.
-
-Dai-link subnode properties and subnodes:
-
-If dai-link subnode is omitted and the subnode properties are directly
-under "sound"-node the subnode property and subnode names have to be
-prefixed with "simple-audio-card,"-prefix.
-
-Required dai-link subnodes:
-
-- cpu : CPU sub-node
-- codec : CODEC sub-node
-
-Optional dai-link subnode properties:
-
-- format : CPU/CODEC common audio format.
- "i2s", "right_j", "left_j" , "dsp_a"
- "dsp_b", "ac97", "pdm", "msb", "lsb"
-- frame-master : Indicates dai-link frame master.
- phandle to a cpu or codec subnode.
-- bitclock-master : Indicates dai-link bit clock master.
- phandle to a cpu or codec subnode.
-- bitclock-inversion : bool property. Add this if the
- dai-link uses bit clock inversion.
-- frame-inversion : bool property. Add this if the
- dai-link uses frame clock inversion.
-- mclk-fs : Multiplication factor between stream
- rate and codec mclk, applied only for
- the dai-link.
-
-For backward compatibility the frame-master and bitclock-master
-properties can be used as booleans in codec subnode to indicate if the
-codec is the dai-link frame or bit clock master. In this case there
-should be no dai-link node, the same properties should not be present
-at sound-node level, and the bitclock-inversion and frame-inversion
-properties should also be placed in the codec node if needed.
-
-Required CPU/CODEC subnodes properties:
-
-- sound-dai : phandle and port of CPU/CODEC
-
-Optional CPU/CODEC subnodes properties:
-
-- dai-tdm-slot-num : Please refer to tdm-slot.txt.
-- dai-tdm-slot-width : Please refer to tdm-slot.txt.
-- clocks / system-clock-frequency : specify subnode's clock if needed.
- it can be specified via "clocks" if system has
- clock node (= common clock), or "system-clock-frequency"
- (if system doens't support common clock)
- If a clock is specified, it is
- enabled with clk_prepare_enable()
- in dai startup() and disabled with
- clk_disable_unprepare() in dai
- shutdown().
- If a clock is specified and a
- multiplication factor is given with
- mclk-fs, the clock will be set to the
- calculated mclk frequency when the
- stream starts.
-- system-clock-direction-out : specifies clock direction as 'out' on
- initialization. It is useful for some aCPUs with
- fixed clocks.

-STMicroelectronics STM32 SPI/I2S Controller
-
-The SPI/I2S block supports I2S/PCM protocols when configured on I2S mode.
-Only some SPI instances support I2S.
-
-Required properties:
- - compatible: Must be "st,stm32h7-i2s"
- - reg: Offset and length of the device's register set.
- - interrupts: Must contain the interrupt line id.
- - clocks: Must contain phandle and clock specifier pairs for each entry
- in clock-names.
- - clock-names: Must contain "i2sclk", "pclk", "x8k" and "x11k".
- "i2sclk": clock which feeds the internal clock generator
- "pclk": clock which feeds the peripheral bus interface
- "x8k": I2S parent clock for sampling rates multiple of 8kHz.
- "x11k": I2S parent clock for sampling rates multiple of 11.025kHz.
- - dmas: DMA specifiers for tx and rx dma.
- See Documentation/devicetree/bindings/dma/stm32-dma.txt.
- - dma-names: Identifier for each DMA request line. Must be "tx" and "rx".
- - pinctrl-names: should contain only value "default"
- - pinctrl-0: see Documentation/devicetree/bindings/pinctrl/st,stm32-pinctrl.yaml
-
-Optional properties:
- - resets: Reference to a reset controller asserting the reset controller
-
-The device node should contain one 'port' child node with one child 'endpoint'
-node, according to the bindings defined in Documentation/devicetree/bindings/
-graph.txt.

-The SPDIFRX peripheral, is designed to receive an S/PDIF flow compliant with
-IEC-60958 and IEC-61937.
-
-Required properties:
- - compatible: should be "st,stm32h7-spdifrx"
- - reg: cpu DAI IP base address and size
- - clocks: must contain an entry for kclk (used as S/PDIF signal reference)
- - clock-names: must contain "kclk"
- - interrupts: cpu DAI interrupt line
- - dmas: DMA specifiers for audio data DMA and iec control flow DMA
- See STM32 DMA bindings, Documentation/devicetree/bindings/dma/stm32-dma.txt
- - dma-names: two dmas have to be defined, "rx" and "rx-ctrl"
-
-Optional properties:
- - resets: Reference to a reset controller asserting the SPDIFRX
-
-The device node should contain one 'port' child node with one child 'endpoint'
-node, according to the bindings defined in Documentation/devicetree/bindings/
-graph.txt.

+ The audio support on the board is using pcm3168a codec connected to McASP10
+ serializers in parallel setup.
+ The pcm3168a SCKI clock is sourced from j721e AUDIO_REFCLK2 pin.
+ In order to support 48KHz and 44.1KHz family of sampling rates the parent
+ clock for AUDIO_REFCLK2 needs to be changed between PLL4 (for 48KHz) and
+ PLL15 (for 44.1KHz). The same PLLs are used for McASP10's AUXCLK clock via
+ different HSDIVIDER.
+
+ Clocking setup for j721e:
+ 48KHz family:
+ PLL4 ---> PLL4_HSDIV0 ---> MCASP10_AUXCLK ---> McASP10.auxclk
+ |-> PLL4_HSDIV2 ---> AUDIO_REFCLK2 ---> pcm3168a.SCKI
+
+ 44.1KHz family:
+ PLL15 ---> PLL15_HSDIV0 ---> MCASP10_AUXCLK ---> McASP10.auxclk
+ |-> PLL15_HSDIV2 ---> AUDIO_REFCLK2 ---> pcm3168a.SCKI
+

+title: Texas Instruments J721e Common Processor Board Audio Support
+
+maintainers:
+ - Peter Ujfalusi <peter.ujfalusi@ti.com>
+
+description: |
+ The Infotainment board plugs into the Common Processor Board, the support of the
+ extension board is extending the CPB audio support, decribed in:
+ sound/ti,j721e-cpb-audio.txt
+
+ The audio support on the Infotainment Expansion Board consists of McASP0
+ connected to two pcm3168a codecs with dedicated set of serializers to each.
+ The SCKI for pcm3168a is sourced from j721e AUDIO_REFCLK0 pin.
+
+ In order to support 48KHz and 44.1KHz family of sampling rates the parent clock
+ for AUDIO_REFCLK0 needs to be changed between PLL4 (for 48KHz) and PLL15 (for
+ 44.1KHz). The same PLLs are used for McASP0's AUXCLK clock via different
+ HSDIVIDER.
+
+ Note: the same PLL4 and PLL15 is used by the audio support on the CPB!
+
+ Clocking setup for 48KHz family:
+ PLL4 ---> PLL4_HSDIV0 ---> MCASP10_AUXCLK ---> McASP10.auxclk
+ | |-> MCASP0_AUXCLK ---> McASP0.auxclk
+ |
+ |-> PLL4_HSDIV2 ---> AUDIO_REFCLK2 ---> pcm3168a.SCKI
+ |-> AUDIO_REFCLK0 ---> pcm3168a_a/b.SCKI
+
+ Clocking setup for 44.1KHz family:
+ PLL15 ---> PLL15_HSDIV0 ---> MCASP10_AUXCLK ---> McASP10.auxclk
+ | |-> MCASP0_AUXCLK ---> McASP0.auxclk
+ |
+ |-> PLL15_HSDIV2 ---> AUDIO_REFCLK2 ---> pcm3168a.SCKI
+ |-> AUDIO_REFCLK0 ---> pcm3168a_a/b.SCKI

- - "fsl,imx1-cspi" for SPI compatible with the one integrated on i.MX1
- - "fsl,imx21-cspi" for SPI compatible with the one integrated on i.MX21
- - "fsl,imx27-cspi" for SPI compatible with the one integrated on i.MX27

- - "fsl,imx53-ecspi" for SPI compatible with the one integrated on i.MX53 and later Soc
- - "fsl,imx8mq-ecspi" for SPI compatible with the one integrated on i.MX8M
-- reg : Offset and length of the register set for the device
-- interrupts : Should contain CSPI/eCSPI interrupt
-- clocks : Clock specifiers for both ipg and per clocks.
-- clock-names : Clock names should include both "ipg" and "per"
-See the clock consumer binding,
- Documentation/devicetree/bindings/clock/clock-bindings.txt
-
-Recommended properties:
-- cs-gpios : GPIOs to use as chip selects, see spi-bus.txt. While the native chip
-select lines can be used, they appear to always generate a pulse between each
-word of a transfer. Most use cases will require GPIO based chip selects to
-generate a valid transaction.
-
-Optional properties:
-- num-cs : Number of total chip selects, see spi-bus.txt.
-- dmas: DMA specifiers for tx and rx dma. See the DMA client binding,
-Documentation/devicetree/bindings/dma/dma.txt.
-- dma-names: DMA request names, if present, should include "tx" and "rx".
-- fsl,spi-rdy-drctl: Integer, representing the value of DRCTL, the register
-controlling the SPI_READY handling. Note that to enable the DRCTL consideration,
-the SPI_READY mode-flag needs to be set too.
-Valid values are: 0 (disabled), 1 (edge-triggered burst) and 2 (level-triggered burst).

-STMicroelectronics STM32 SPI Controller
-
-The STM32 SPI controller is used to communicate with external devices using
-the Serial Peripheral Interface. It supports full-duplex, half-duplex and
-simplex synchronous serial communication with external devices. It supports
-from 4 to 32-bit data size. Although it can be configured as master or slave,
-only master is supported by the driver.
-
-Required properties:
-- compatible: Should be one of:
- "st,stm32h7-spi"
- "st,stm32f4-spi"
-- reg: Offset and length of the device's register set.
-- interrupts: Must contain the interrupt id.
-- clocks: Must contain an entry for spiclk (which feeds the internal clock
- generator).
-- #address-cells: Number of cells required to define a chip select address.
-- #size-cells: Should be zero.
-
-Optional properties:
-- resets: Must contain the phandle to the reset controller.
-- A pinctrl state named "default" may be defined to set pins in mode of
- operation for SPI transfer.
-- dmas: DMA specifiers for tx and rx dma. DMA fifo mode must be used. See the
- STM32 DMA bindings, Documentation/devicetree/bindings/dma/stm32-dma.txt.
-- dma-names: DMA request names should include "tx" and "rx" if present.
-- cs-gpios: list of GPIO chip selects. See the SPI bus bindings,

-Milbeaut SRAM for smp bringup
-
-Milbeaut SoCs use a part of the sram for the bringup of the secondary cores.
-Once they get powered up in the bootloader, they stay at the specific part
-of the sram.
-Therefore the part needs to be added as the sub-node of mmio-sram.
-
-Required sub-node properties:
-- compatible : should be "socionext,milbeaut-smp-sram"
-
-Example:
-
- sram: sram@0 {

- #address-cells = <1>;
- #size-cells = <1>;

-* Renesas SMP SRAM
-
-Renesas R-Car Gen2 and RZ/G1 SoCs need a small piece of SRAM for the jump stub
-for secondary CPU bringup and CPU hotplug.
-This memory is reserved by adding a child node to a "mmio-sram" node, cfr.

----------------------------
-
-Some devices need to request to the SRAM controller to map an SRAM for
-their exclusive use.
-
-The relationship between such a device and an SRAM section is
-expressed through the allwinner,sram property, that will take a
-phandle and an argument.
-
-This valid values for this argument are:

+==========================================
+Submitting devicetree (DT) binding patches
+==========================================
+
+I. For patch submitters
+=======================
+
+ 0) Normal patch submission rules from Documentation/process/submitting-patches.rst
+ applies.
+
+ 1) The Documentation/ and include/dt-bindings/ portion of the patch should
+ be a separate patch. The preferred subject prefix for binding patches is::
+
+ "dt-bindings: <binding dir>: ..."
+
+ The 80 characters of the subject are precious. It is recommended to not
+ use "Documentation" or "doc" because that is implied. All bindings are
+ docs. Repeating "binding" again should also be avoided.
+
+ 2) DT binding files are written in DT schema format using json-schema
+ vocabulary and YAML file format. The DT binding files must pass validation
+ by running::
+
+ make dt_binding_check
+
+ See ../writing-schema.rst for more details about schema and tools setup.
+
+ 3) DT binding files should be dual licensed. The preferred license tag is
+ (GPL-2.0-only OR BSD-2-Clause).
+
+ 4) Submit the entire series to the devicetree mailinglist at
+
+ devicetree@vger.kernel.org
+
+ and Cc: the DT maintainers. Use scripts/get_maintainer.pl to identify
+ all of the DT maintainers.
+
+ 5) The Documentation/ portion of the patch should come in the series before
+ the code implementing the binding.
+
+ 6) Any compatible strings used in a chip or board DTS file must be
+ previously documented in the corresponding DT binding text file
+ in Documentation/devicetree/bindings. This rule applies even if
+ the Linux device driver does not yet match on the compatible
+ string. [ checkpatch will emit warnings if this step is not
+ followed as of commit bff5da4335256513497cc8c79f9a9d1665e09864
+ ("checkpatch: add DT compatible string documentation checks"). ]
+
+ 7) The wildcard "<chip>" may be used in compatible strings, as in
+ the following example:
+
+ - compatible: Must contain '"nvidia,<chip>-pcie",
+ "nvidia,tegra20-pcie"' where <chip> is tegra30, tegra132, ...
+
+ As in the above example, the known values of "<chip>" should be
+ documented if it is used.
+
+ 8) If a documented compatible string is not yet matched by the
+ driver, the documentation should also include a compatible
+ string that is matched by the driver (as in the "nvidia,tegra20-pcie"
+ example above).
+
+
+II. For kernel maintainers
+==========================
+
+ 1) If you aren't comfortable reviewing a given binding, reply to it and ask
+ the devicetree maintainers for guidance. This will help them prioritize
+ which ones to review and which ones are ok to let go.
+
+ 2) For driver (not subsystem) bindings: If you are comfortable with the
+ binding, and it hasn't received an Acked-by from the devicetree
+ maintainers after a few weeks, go ahead and take it.
+
+ Subsystem bindings (anything affecting more than a single device)
+ then getting a devicetree maintainer to review it is required.
+
+ 3) For a series going though multiple trees, the binding patch should be
+ kept with the driver using the binding.
+
+III. Notes
+==========
+
+ 0) Please see ...bindings/ABI.txt for details regarding devicetree ABI.
+
+ 1) This document is intended as a general familiarization with the process as
+ decided at the 2013 Kernel Summit. When in doubt, the current word of the
+ devicetree maintainers overrules this document. In that situation, a patch
+ updating this document would be appreciated.

-* Temperature Monitor (TEMPMON) on Freescale i.MX SoCs
-
-Required properties:
-- compatible : must be one of following:
- - "fsl,imx6q-tempmon" for i.MX6Q,
- - "fsl,imx6sx-tempmon" for i.MX6SX,
- - "fsl,imx7d-tempmon" for i.MX7S/D.
-- interrupts : the interrupt output of the controller:
- i.MX6Q has one IRQ which will be triggered when temperature is higher than high threshold,
- i.MX6SX and i.MX7S/D have two more IRQs than i.MX6Q, one is IRQ_LOW and the other is IRQ_PANIC,
- when temperature is below than low threshold, IRQ_LOW will be triggered, when temperature
- is higher than panic threshold, system will auto reboot by SRC module.
-- fsl,tempmon : phandle pointer to system controller that contains TEMPMON
- control registers, e.g. ANATOP on imx6q.
-- nvmem-cells: A phandle to the calibration cells provided by ocotp.
-- nvmem-cell-names: Should be "calib", "temp_grade".
-
-Deprecated properties:
-- fsl,tempmon-data : phandle pointer to fuse controller that contains TEMPMON
- calibration data, e.g. OCOTP on imx6q. The details about calibration data
- can be found in SoC Reference Manual.
-
-Direct access to OCOTP via fsl,tempmon-data is incorrect on some newer chips
-because it does not handle OCOTP clock requirements.
-
-Optional properties:
-- clocks : thermal sensor's clock source.
-
-Example:
-ocotp: ocotp@21bc000 {
- #address-cells = <1>;
- #size-cells = <1>;
- compatible = "fsl,imx6sx-ocotp", "syscon";

-* DT bindings for Renesas R-Car Gen3 Thermal Sensor driver
-
-On R-Car Gen3 SoCs, the thermal sensor controllers (TSC) control the thermal
-sensors (THS) which are the analog circuits for measuring temperature (Tj)
-inside the LSI.
-
-Required properties:
-- compatible : "renesas,<soctype>-thermal",
- Examples with soctypes are:
- - "renesas,r8a774a1-thermal" (RZ/G2M)
- - "renesas,r8a7795-thermal" (R-Car H3)
- - "renesas,r8a7796-thermal" (R-Car M3-W)
- - "renesas,r8a77965-thermal" (R-Car M3-N)
- - "renesas,r8a77980-thermal" (R-Car V3H)
-- reg : Address ranges of the thermal registers. Each sensor
- needs one address range. Sorting must be done in
- increasing order according to datasheet, i.e.
- TSC1, TSC2, ...
-- clocks : Must contain a reference to the functional clock.
-- #thermal-sensor-cells : must be <1>.
-
-Optional properties:
-
-- interrupts : interrupts routed to the TSC (must be 3).
-- power-domain : Must contain a reference to the power domain. This
- property is mandatory if the thermal sensor instance
- is part of a controllable power domain.
-
-Example:
-
- tsc: thermal@e6198000 {
- compatible = "renesas,r8a7795-thermal";
- reg = <0 0xe6198000 0 0x100>,

-Binding for Thermal Sensor for STMicroelectronics STM32 series of SoCs.
-
-On STM32 SoCs, the Digital Temperature Sensor (DTS) is in charge of managing an
-analog block which delivers a frequency depending on the internal SoC's
-temperature. By using a reference frequency, DTS is able to provide a sample
-number which can be translated into a temperature by the user.
-
-DTS provides interrupt notification mechanism by threshold. This mechanism
-offers two temperature trip points: passive and critical. The first is intended
-for passive cooling notification while the second is used for over-temperature
-reset.
-
-Required parameters:
--------------------
-
-compatible: Should be "st,stm32-thermal"
-reg: This should be the physical base address and length of the
- sensor's registers.
-clocks: Phandle of the clock used by the thermal sensor.
- See: Documentation/devicetree/bindings/clock/clock-bindings.txt
-clock-names: Should be "pclk" for register access clock and reference clock.
- See: Documentation/devicetree/bindings/resource-names.txt
-#thermal-sensor-cells: Should be 0. See ./thermal.txt for a description.
-interrupts: Standard way to define interrupt number.
-
-Example:
-
- thermal-zones {
- cpu_thermal: cpu-thermal {
- polling-delay-passive = <0>;
- polling-delay = <0>;

+description: |
+ Thermal management is achieved in devicetree by describing the sensor hardware
+ and the software abstraction of cooling devices and thermal zones required to
+ take appropriate action to mitigate thermal overload.
+
+ The following node types are used to completely describe a thermal management
+ system in devicetree:
+ - thermal-sensor: device that measures temperature, has SoC-specific bindings
+ - cooling-device: device used to dissipate heat either passively or actively
+ - thermal-zones: a container of the following node types used to describe all
+ thermal data for the platform
+
+ This binding describes the cooling devices.
+
+ There are essentially two ways to provide control on power dissipation:
+ - Passive cooling: by means of regulating device performance. A typical
+ passive cooling mechanism is a CPU that has dynamic voltage and frequency
+ scaling (DVFS), and uses lower frequencies as cooling states.
+ - Active cooling: by means of activating devices in order to remove the
+ dissipated heat, e.g. regulating fan speeds.
+
+ Any cooling device has a range of cooling states (i.e. different levels of
+ heat dissipation). They also have a way to determine the state of cooling in
+ which the device is. For example, a fan's cooling states correspond to the
+ different fan speeds possible. Cooling states are referred to by single
+ unsigned integers, where larger numbers mean greater heat dissipation. The
+ precise set of cooling states associated with a device should be defined in
+ a particular device's binding.

-* Thermal Framework Device Tree descriptor
-
-This file describes a generic binding to provide a way of
-defining hardware thermal structure using device tree.
-A thermal structure includes thermal zones and their components,
-such as trip points, polling intervals, sensors and cooling devices
-binding descriptors.
-
-The target of device tree thermal descriptors is to describe only
-the hardware thermal aspects. The thermal device tree bindings are
-not about how the system must control or which algorithm or policy
-must be taken in place.
-
-There are five types of nodes involved to describe thermal bindings:
-- thermal sensors: devices which may be used to take temperature
- measurements.
-- cooling devices: devices which may be used to dissipate heat.
-- trip points: describe key temperatures at which cooling is recommended. The
- set of points should be chosen based on hardware limits.
-- cooling maps: used to describe links between trip points and cooling devices;
-- thermal zones: used to describe thermal data within the hardware;
-
-The following is a description of each of these node types.
-
-* Thermal sensor devices
-
-Thermal sensor devices are nodes providing temperature sensing capabilities on
-thermal zones. Typical devices are I2C ADC converters and bandgaps. These are
-nodes providing temperature data to thermal zones. Thermal sensor devices may
-control one or more internal sensors.
-
-Required property:
-- #thermal-sensor-cells: Used to provide sensor device specific information
- Type: unsigned while referring to it. Typically 0 on thermal sensor
- Size: one cell nodes with only one sensor, and at least 1 on nodes
- with several internal sensors, in order
- to identify uniquely the sensor instances within
- the IC. See thermal zone binding for more details
- on how consumers refer to sensor devices.
-
-* Cooling device nodes
-
-Cooling devices are nodes providing control on power dissipation. There
-are essentially two ways to provide control on power dissipation. First
-is by means of regulating device performance, which is known as passive
-cooling. A typical passive cooling is a CPU that has dynamic voltage and
-frequency scaling (DVFS), and uses lower frequencies as cooling states.
-Second is by means of activating devices in order to remove
-the dissipated heat, which is known as active cooling, e.g. regulating
-fan speeds. In both cases, cooling devices shall have a way to determine
-the state of cooling in which the device is.
-
-Any cooling device has a range of cooling states (i.e. different levels
-of heat dissipation). For example a fan's cooling states correspond to
-the different fan speeds possible. Cooling states are referred to by
-single unsigned integers, where larger numbers mean greater heat
-dissipation. The precise set of cooling states associated with a device
-should be defined in a particular device's binding.
-For more examples of cooling devices, refer to the example sections below.
-
-Required properties:
-- #cooling-cells: Used to provide cooling device specific information
- Type: unsigned while referring to it. Must be at least 2, in order
- Size: one cell to specify minimum and maximum cooling state used
- in the reference. The first cell is the minimum
- cooling state requested and the second cell is
- the maximum cooling state requested in the reference.
- See Cooling device maps section below for more details
- on how consumers refer to cooling devices.
-
-* Trip points
-
-The trip node is a node to describe a point in the temperature domain
-in which the system takes an action. This node describes just the point,
-not the action.
-
-Required properties:
-- temperature: An integer indicating the trip temperature level,
- Type: signed in millicelsius.
- Size: one cell
-
-- hysteresis: A low hysteresis value on temperature property (above).
- Type: unsigned This is a relative value, in millicelsius.
- Size: one cell
-
-- type: a string containing the trip type. Expected values are:
- "active": A trip point to enable active cooling
- "passive": A trip point to enable passive cooling
- "hot": A trip point to notify emergency
- "critical": Hardware not reliable.
- Type: string
-
-* Cooling device maps
-
-The cooling device maps node is a node to describe how cooling devices
-get assigned to trip points of the zone. The cooling devices are expected
-to be loaded in the target system.
-
-Required properties:
-- cooling-device: A list of phandles of cooling devices with their specifiers,
- Type: phandle + referring to which cooling devices are used in this
- cooling specifier binding. In the cooling specifier, the first cell
- is the minimum cooling state and the second cell
- is the maximum cooling state used in this map.
-- trip: A phandle of a trip point node within the same thermal
- Type: phandle of zone.
- trip point node
-
-Optional property:
-- contribution: The cooling contribution to the thermal zone of the
- Type: unsigned referred cooling device at the referred trip point.
- Size: one cell The contribution is a ratio of the sum
- of all cooling contributions within a thermal zone.
-
-Note: Using the THERMAL_NO_LIMIT (-1UL) constant in the cooling-device phandle
-limit specifier means:
-(i) - minimum state allowed for minimum cooling state used in the reference.
-(ii) - maximum state allowed for maximum cooling state used in the reference.
-Refer to include/dt-bindings/thermal/thermal.h for definition of this constant.
-
-* Thermal zone nodes
-
-The thermal zone node is the node containing all the required info
-for describing a thermal zone, including its cooling device bindings. The
-thermal zone node must contain, apart from its own properties, one sub-node
-containing trip nodes and one sub-node containing all the zone cooling maps.
-
-Required properties:
-- polling-delay: The maximum number of milliseconds to wait between polls
- Type: unsigned when checking this thermal zone.
- Size: one cell
-
-- polling-delay-passive: The maximum number of milliseconds to wait
- Type: unsigned between polls when performing passive cooling.
- Size: one cell
-
-- thermal-sensors: A list of thermal sensor phandles and sensor specifier
- Type: list of used while monitoring the thermal zone.
- phandles + sensor
- specifier
-
-- trips: A sub-node which is a container of only trip point nodes
- Type: sub-node required to describe the thermal zone.
-
-- cooling-maps: A sub-node which is a container of only cooling device
- Type: sub-node map nodes, used to describe the relation between trips
- and cooling devices.
-
-Optional property:
-- coefficients: An array of integers (one signed cell) containing
- Type: array coefficients to compose a linear relation between
- Elem size: one cell the sensors listed in the thermal-sensors property.
- Elem type: signed Coefficients defaults to 1, in case this property
- is not specified. A simple linear polynomial is used:
- Z = c0 * x0 + c1 * x1 + ... + c(n-1) * x(n-1) + cn.
-
- The coefficients are ordered and they match with sensors
- by means of sensor ID. Additional coefficients are
- interpreted as constant offset.
-
-- sustainable-power: An estimate of the sustainable power (in mW) that the
- Type: unsigned thermal zone can dissipate at the desired
- Size: one cell control temperature. For reference, the
- sustainable power of a 4'' phone is typically
- 2000mW, while on a 10'' tablet is around
- 4500mW.
-
-Note: The delay properties are bound to the maximum dT/dt (temperature
-derivative over time) in two situations for a thermal zone:
-(i) - when passive cooling is activated (polling-delay-passive); and
-(ii) - when the zone just needs to be monitored (polling-delay) or
-when active cooling is activated.
-
-The maximum dT/dt is highly bound to hardware power consumption and dissipation
-capability. The delays should be chosen to account for said max dT/dt,
-such that a device does not cross several trip boundaries unexpectedly
-between polls. Choosing the right polling delays shall avoid having the
-device in temperature ranges that may damage the silicon structures and
-reduce silicon lifetime.
-
-* The thermal-zones node
-
-The "thermal-zones" node is a container for all thermal zone nodes. It shall
-contain only sub-nodes describing thermal zones as in the section
-"Thermal zone nodes". The "thermal-zones" node appears under "/".
-
-* Examples
-
-Below are several examples on how to use thermal data descriptors
-using device tree bindings:
-
-(a) - CPU thermal zone
-
-The CPU thermal zone example below describes how to setup one thermal zone
-using one single sensor as temperature source and many cooling devices and
-power dissipation control sources.
-
-#include <dt-bindings/thermal/thermal.h>
-
-cpus {
- /*
- * Here is an example of describing a cooling device for a DVFS
- * capable CPU. The CPU node describes its four OPPs.
- * The cooling states possible are 0..3, and they are
- * used as OPP indexes. The minimum cooling state is 0, which means
- * all four OPPs can be available to the system. The maximum
- * cooling state is 3, which means only the lowest OPPs (198MHz@0.85V)
- * can be available in the system.

- map1 {
- trip = <&cpu_alert1>;
- cooling-device = <&fan0 5 THERMAL_NO_LIMIT>, <&cpu0 THERMAL_NO_LIMIT THERMAL_NO_LIMIT>;
- };
- };
- };
-};
-
-In the example above, the ADC sensor (bandgap0) at address 0x0000ED00 is
-used to monitor the zone 'cpu-thermal' using its sole sensor. A fan
-device (fan0) is controlled via I2C bus 1, at address 0x48, and has ten
-different cooling states 0-9. It is used to remove the heat out of
-the thermal zone 'cpu-thermal' using its cooling states
-from its minimum to 4, when it reaches trip point 'cpu_alert0'
-at 90C, as an example of active cooling. The same cooling device is used at
-'cpu_alert1', but from 5 to its maximum state. The cpu@0 device is also
-linked to the same thermal zone, 'cpu-thermal', as a passive cooling device,
-using all its cooling states at trip point 'cpu_alert1',
-which is a trip point at 100C. On the thermal zone 'cpu-thermal', at the
-temperature of 125C, represented by the trip point 'cpu_crit', the silicon
-is not reliable anymore.
-
-(b) - IC with several internal sensors
-
-The example below describes how to deploy several thermal zones based off a
-single sensor IC, assuming it has several internal sensors. This is a common
-case on SoC designs with several internal IPs that may need different thermal
-requirements, and thus may have their own sensor to monitor or detect internal
-hotspots in their silicon.
-
-#include <dt-bindings/thermal/thermal.h>
-
-ocp {

- };

- /* each zone within the SoC may have its own trips */
- cpu_alert: cpu-alert {

- hysteresis = <2000>; /* millicelsius */
- type = "passive";
- };
- cpu_crit: cpu-crit {

- type = "critical";
- };
- };
-
- cooling-maps {
- /* each zone within the SoC may have its own cooling */
- ...
- };
- };
-
- gpu_thermal: gpu-thermal {
- polling-delay-passive = <120>; /* milliseconds */
- polling-delay = <1000>; /* milliseconds */
-
- /* sensor ID */
- thermal-sensors = <&bandgap0 1>;
-
- trips {
- /* each zone within the SoC may have its own trips */
- gpu_alert: gpu-alert {
- temperature = <90000>; /* millicelsius */
- hysteresis = <2000>; /* millicelsius */
- type = "passive";
- };
- gpu_crit: gpu-crit {
- temperature = <105000>; /* millicelsius */
- hysteresis = <2000>; /* millicelsius */
- type = "critical";
- };
- };
-
- cooling-maps {
- /* each zone within the SoC may have its own cooling */
- ...
- };
- };
-
- dsp_thermal: dsp-thermal {
- polling-delay-passive = <50>; /* milliseconds */
- polling-delay = <1000>; /* milliseconds */
-
- /* sensor ID */
- thermal-sensors = <&bandgap0 2>;
-
- trips {
- /* each zone within the SoC may have its own trips */
- dsp_alert: dsp-alert {
- temperature = <90000>; /* millicelsius */
- hysteresis = <2000>; /* millicelsius */
- type = "passive";
- };
- dsp_crit: gpu-crit {
- temperature = <135000>; /* millicelsius */
- hysteresis = <2000>; /* millicelsius */
- type = "critical";
- };
- };
-
- cooling-maps {
- /* each zone within the SoC may have its own cooling */
- ...
- };
- };
-};
-
-In the example above, there is one bandgap IC which has the capability to
-monitor three sensors. The hardware has been designed so that sensors are
-placed on different places in the DIE to monitor different temperature
-hotspots: one for CPU thermal zone, one for GPU thermal zone and the
-other to monitor a DSP thermal zone.
-
-Thus, there is a need to assign each sensor provided by the bandgap IC
-to different thermal zones. This is achieved by means of using the
-#thermal-sensor-cells property and using the first cell of the sensor
-specifier as sensor ID. In the example, then, <bandgap 0> is used to
-monitor CPU thermal zone, <bandgap 1> is used to monitor GPU thermal
-zone and <bandgap 2> is used to monitor DSP thermal zone. Each zone
-may be uncorrelated, having its own dT/dt requirements, trips
-and cooling maps.
-
-
-(c) - Several sensors within one single thermal zone
-
-The example below illustrates how to use more than one sensor within
-one thermal zone.
-
-#include <dt-bindings/thermal/thermal.h>
-
-&i2c1 {
- ...
- /*
- * A simple IC with a single temperature sensor.
- */
- adc: sensor@49 {
- ...
- #thermal-sensor-cells = <0>;
- };
-};
-
-ocp {
- ...
- /*
- * A simple IC with a single bandgap temperature sensor.
- */
- bandgap0: bandgap@0000ed00 {
- ...
- #thermal-sensor-cells = <0>;
- };
-};
-
-thermal-zones {
- cpu_thermal: cpu-thermal {
- polling-delay-passive = <250>; /* milliseconds */
- polling-delay = <1000>; /* milliseconds */
-
- thermal-sensors = <&bandgap0>, /* cpu */
- <&adc>; /* pcb north */
-
- /* hotspot = 100 * bandgap - 120 * adc + 484 */
- coefficients = <100 -120 484>;
-
- trips {
- ...
- };
-
- cooling-maps {
- ...
- };
- };
-};
-
-In some cases, there is a need to use more than one sensor to extrapolate
-a thermal hotspot in the silicon. The above example illustrates this situation.
-For instance, it may be the case that a sensor external to CPU IP may be placed
-close to CPU hotspot and together with internal CPU sensor, it is used
-to determine the hotspot. Assuming this is the case for the above example,
-the hypothetical extrapolation rule would be:
- hotspot = 100 * bandgap - 120 * adc + 484
-
-In other context, the same idea can be used to add fixed offset. For instance,
-consider the hotspot extrapolation rule below:
- hotspot = 1 * adc + 6000
-
-In the above equation, the hotspot is always 6C higher than what is read
-from the ADC sensor. The binding would be then:
- thermal-sensors = <&adc>;
-
- /* hotspot = 1 * adc + 6000 */
- coefficients = <1 6000>;
-
-(d) - Board thermal
-
-The board thermal example below illustrates how to setup one thermal zone
-with many sensors and many cooling devices.
-
-#include <dt-bindings/thermal/thermal.h>
-
-&i2c1 {
- ...
- /*
- * An IC with several temperature sensor.
- */
- adc_dummy: sensor@50 {
- ...
- #thermal-sensor-cells = <1>; /* sensor internal ID */
- };
-};
-
-thermal-zones {
- batt-thermal {
- polling-delay-passive = <500>; /* milliseconds */
- polling-delay = <2500>; /* milliseconds */
-
- /* sensor ID */
- thermal-sensors = <&adc_dummy 4>;
-
- trips {
- ...
- };
-
- cooling-maps {
- ...
- };
- };
-
- board_thermal: board-thermal {
- polling-delay-passive = <1000>; /* milliseconds */
- polling-delay = <2500>; /* milliseconds */
-
- /* sensor ID */
- thermal-sensors = <&adc_dummy 0>, /* pcb top edge */
- <&adc_dummy 1>, /* lcd */
- <&adc_dummy 2>; /* back cover */
- /*
- * An array of coefficients describing the sensor
- * linear relation. E.g.:
- * z = c1*x1 + c2*x2 + c3*x3
- */
- coefficients = <1200 -345 890>;
-
- sustainable-power = <2500>;
-
- trips {
- /* Trips are based on resulting linear equation */
- cpu_trip: cpu-trip {
- temperature = <60000>; /* millicelsius */
- hysteresis = <2000>; /* millicelsius */
- type = "passive";
- };
- gpu_trip: gpu-trip {
- temperature = <55000>; /* millicelsius */
- hysteresis = <2000>; /* millicelsius */
- type = "passive";
- }
- lcd_trip: lcp-trip {
- temperature = <53000>; /* millicelsius */
- hysteresis = <2000>; /* millicelsius */
- type = "passive";
- };
- crit_trip: crit-trip {
- temperature = <68000>; /* millicelsius */
- hysteresis = <2000>; /* millicelsius */
- type = "critical";
- };
- };
-
- cooling-maps {
- map0 {
- trip = <&cpu_trip>;
- cooling-device = <&cpu0 0 2>;
- contribution = <55>;
- };
- map1 {
- trip = <&gpu_trip>;
- cooling-device = <&gpu0 0 2>;
- contribution = <20>;
- };
- map2 {
- trip = <&lcd_trip>;
- cooling-device = <&lcd0 5 10>;
- contribution = <15>;
- };
- };
- };
-};
-
-The above example is a mix of previous examples, a sensor IP with several internal
-sensors used to monitor different zones, one of them is composed by several sensors and
-with different cooling devices.

-* Renesas R-Car Compare Match Timer (CMT)
-
-The CMT is a multi-channel 16/32/48-bit timer/counter with configurable clock
-inputs and programmable compare match.
-
-Channels share hardware resources but their counter and compare match value
-are independent. A particular CMT instance can implement only a subset of the
-channels supported by the CMT model. Channel indices represent the hardware
-position of the channel in the CMT and don't match the channel numbers in the
-datasheets.
-

+description:
+ The CMT is a multi-channel 16/32/48-bit timer/counter with configurable clock
+ inputs and programmable compare match.
+
+ Channels share hardware resources but their counter and compare match values
+ are independent. A particular CMT instance can implement only a subset of the
+ channels supported by the CMT model. Channel indices represent the hardware
+ position of the channel in the CMT and don't match the channel numbers in the
+ datasheets.

-Samsung's Multi Core Timer (MCT)
-
-The Samsung's Multi Core Timer (MCT) module includes two main blocks, the
-global timer and CPU local timers. The global timer is a 64-bit free running
-up-counter and can generate 4 interrupts when the counter reaches one of the
-four preset counter values. The CPU local timers are 32-bit free running
-down-counters and generate an interrupt when the counter expires. There is
-one CPU local timer instantiated in MCT for every CPU in the system.
-
-Required properties:
-
-- compatible: should be "samsung,exynos4210-mct".
- (a) "samsung,exynos4210-mct", for mct compatible with Exynos4210 mct.
- (b) "samsung,exynos4412-mct", for mct compatible with Exynos4412 mct.
-
-- reg: base address of the mct controller and length of the address space
- it occupies.
-
-- interrupts: the list of interrupts generated by the controller. The following
- should be the order of the interrupts specified. The local timer interrupts
- should be specified after the four global timer interrupts have been
- specified.
-
- 0: Global Timer Interrupt 0
- 1: Global Timer Interrupt 1
- 2: Global Timer Interrupt 2
- 3: Global Timer Interrupt 3
- 4: Local Timer Interrupt 0
- 5: Local Timer Interrupt 1
- 6: ..
- 7: ..
- i: Local Timer Interrupt n
-
- For MCT block that uses a per-processor interrupt for local timers, such
- as ones compatible with "samsung,exynos4412-mct", only one local timer
- interrupt might be specified, meaning that all local timers use the same
- per processor interrupt.
-
-Example 1: In this example, the IP contains two local timers, using separate
- interrupts, so two local timer interrupts have been specified,
- in addition to four global timer interrupts.
-
- mct@10050000 {
- compatible = "samsung,exynos4210-mct";
- reg = <0x10050000 0x800>;
- interrupts = <0 57 0>, <0 69 0>, <0 70 0>, <0 71 0>,
- <0 42 0>, <0 48 0>;
- };
-
-Example 2: In this example, the timer interrupts are connected to two separate
- interrupt controllers. Hence, an interrupt-map is created to map
- the interrupts to the respective interrupt controllers.
-
- mct@101c0000 {
- compatible = "samsung,exynos4210-mct";
- reg = <0x101C0000 0x800>;
- interrupt-parent = <&mct_map>;
- interrupts = <0>, <1>, <2>, <3>, <4>, <5>;
-
- mct_map: mct-map {
- #interrupt-cells = <1>;
- #address-cells = <0>;
- #size-cells = <0>;
- interrupt-map = <0 &gic 0 57 0>,
- <1 &gic 0 69 0>,
- <2 &combiner 12 6>,
- <3 &combiner 12 7>,
- <4 &gic 0 42 0>,
- <5 &gic 0 48 0>;
- };
- };
-
-Example 3: In this example, the IP contains four local timers, but using
- a per-processor interrupt to handle them. Either all the local
- timer interrupts can be specified, with the same interrupt specifier
- value or just the first one.
-
- mct@10050000 {
- compatible = "samsung,exynos4412-mct";

+description: |+
+ The ASPEED USB 2.0 Virtual Hub Controller implements 1 set of USB Hub
+ register and several sets of Device and Endpoint registers to support
+ the Virtual Hub's downstream USB devices.
+
+ Supported number of devices and endpoints vary depending on hardware
+ revisions. AST2400 and AST2500 Virtual Hub supports 5 downstream devices
+ and 15 generic endpoints, while AST2600 Virtual Hub supports 7 downstream
+ devices and 21 generic endpoints.

-ARM AMBA Primecell SP805 Watchdog
-
-SP805 WDT is a ARM Primecell Peripheral and has a standard-id register that
-can be used to identify the peripheral type, vendor, and revision.
-This value can be used for driver matching.
-
-As SP805 WDT is a primecell IP, it follows the base bindings specified in
-'arm/primecell.txt'
-
-Required properties:
-- compatible: Should be "arm,sp805" & "arm,primecell"
-- reg: Should contain location and length for watchdog timer register
-- clocks: Clocks driving the watchdog timer hardware. This list should be
- 2 clocks. With 2 clocks, the order is wdog_clk, apb_pclk
- wdog_clk can be equal to or be a sub-multiple of the apb_pclk
- frequency
-- clock-names: Shall be "wdog_clk" for first clock and "apb_pclk" for the
- second one
-
-Optional properties:
-- interrupts: Should specify WDT interrupt number
-- timeout-sec: Should specify default WDT timeout in seconds. If unset, the
- default timeout is determined by the driver
-
-Example:
- watchdog@66090000 {
- compatible = "arm,sp805", "arm,primecell";
- reg = <0x66090000 0x1000>;

+ The TI K3 SoC watchdog timer is implemented via the RTI (Real Time
+ Interrupt) IP module. This timer adds a support for windowed watchdog
+ mode, which will signal an error if it is pinged outside the watchdog
+ time window, meaning either too early or too late. The error signal
+ generated can be routed to either interrupt a safety controller or
+ to directly reset the SoC.

+============================================================
+DOs and DON'Ts for designing and writing Devicetree bindings
+============================================================
+
+This is a list of common review feedback items focused on binding design. With
+every rule, there are exceptions and bindings have many gray areas.
+
+For guidelines related to patches, see
+Documentation/devicetree/bindings/submitting-patches.rst
+
+
+Overall design
+==============
+
+- DO attempt to make bindings complete even if a driver doesn't support some
+ features. For example, if a device has an interrupt, then include the
+ 'interrupts' property even if the driver is only polled mode.
+
+- DON'T refer to Linux or "device driver" in bindings. Bindings should be
+ based on what the hardware has, not what an OS and driver currently support.
+
+- DO use node names matching the class of the device. Many standard names are
+ defined in the DT Spec. If there isn't one, consider adding it.
+
+- DO check that the example matches the documentation especially after making
+ review changes.
+
+- DON'T create nodes just for the sake of instantiating drivers. Multi-function
+ devices only need child nodes when the child nodes have their own DT
+ resources. A single node can be multiple providers (e.g. clocks and resets).
+
+- DON'T use 'syscon' alone without a specific compatible string. A 'syscon'
+ hardware block should have a compatible string unique enough to infer the
+ register layout of the entire block (at a minimum).
+
+
+Properties
+==========
+
+- DO make 'compatible' properties specific. DON'T use wildcards in compatible
+ strings. DO use fallback compatibles when devices are the same as or a subset
+ of prior implementations. DO add new compatibles in case there are new
+ features or bugs.
+
+- DO use a vendor prefix on device specific property names. Consider if
+ properties could be common among devices of the same class. Check other
+ existing bindings for similar devices.
+
+- DON'T redefine common properties. Just reference the definition and define
+ constraints specific to the device.
+
+- DO use common property unit suffixes for properties with scientific units.
+ See property-units.txt.
+
+- DO define properties in terms of constraints. How many entries? What are
+ possible values? What is the order?
+
+
+Board/SoC .dts Files
+====================
+
+- DO put all MMIO devices under a bus node and not at the top-level.
+
+- DO use non-empty 'ranges' to limit the size of child buses/devices. 64-bit
+ platforms don't need all devices to have 64-bit address and size.

- Some IP cores actually implement 2 or more logical devices. In
- this case, the device should still describe the whole IP core with
- a single node and add a child node for each logical device. The
- ranges property can be used to translate from parent IP-core to the
- registers of each device. In addition, the parent node should be
- compatible with the bus type 'xlnx,compound', and should contain
- #address-cells and #size-cells, as with any other bus. (Note: this
- makes the assumption that both logical devices have the same bus
- binding. If this is not true, then separate nodes should be used
- for each logical device). The 'cell-index' property can be used to
- enumerate logical devices within an IP core. For example, the
- following is the system.mhs entry for the dual ps2 controller found
- on the ml403 reference design.
-
- BEGIN opb_ps2_dual_ref
- PARAMETER INSTANCE = opb_ps2_dual_ref_0
- PARAMETER HW_VER = 1.00.a
- PARAMETER C_BASEADDR = 0xA9000000
- PARAMETER C_HIGHADDR = 0xA9001FFF
- BUS_INTERFACE SOPB = opb_v20_0
- PORT Sys_Intr1 = ps2_1_intr
- PORT Sys_Intr2 = ps2_2_intr

- PORT Clkpd1 = ps2_clk_tx_1
- PORT Clkpd2 = ps2_clk_tx_2
- PORT Rx1 = ps2_d_rx_1
- PORT Rx2 = ps2_d_rx_2
- PORT Txpd1 = ps2_d_tx_1
- PORT Txpd2 = ps2_d_tx_2
- END
-
- It would result in the following device tree nodes:
-
- opb_ps2_dual_ref_0: opb-ps2-dual-ref@a9000000 {
- #address-cells = <1>;
- #size-cells = <1>;
- compatible = "xlnx,compound";
- ranges = <0 a9000000 2000>;
- // If this device had extra parameters, then they would
- // go here.
- ps2@0 {
- compatible = "xlnx,opb-ps2-dual-ref-1.00.a";
- reg = <0 40>;
- interrupt-parent = <&opb_intc_0>;
- interrupts = <3 0>;

- reg = <1000 40>;
- interrupt-parent = <&opb_intc_0>;
- interrupts = <3 0>;
- cell-index = <0>;
- };
- };
-
- Also, the system.mhs file defines bus attachments from the processor
- to the devices. The device tree structure should reflect the bus
- attachments. Again an example; this system.mhs fragment:
-
- BEGIN ppc405_virtex4

- BUS_INTERFACE SPLB = plb_v34_0

- END
-
- Gives this device tree (some properties removed for clarity):
-
- plb@0 {
- #address-cells = <1>;
- #size-cells = <1>;
- compatible = "xlnx,plb-v34-1.02.a";

-Revision Information
-====================
-
- May 18, 2005: Rev 0.1 - Initial draft, no chapter III yet.
-
- May 19, 2005: Rev 0.2 - Add chapter III and bits & pieces here or
- clarifies the fact that a lot of things are
- optional, the kernel only requires a very
- small device tree, though it is encouraged
- to provide an as complete one as possible.
-
- May 24, 2005: Rev 0.3 - Precise that DT block has to be in RAM
- - Misc fixes
- - Define version 3 and new format version 16
- for the DT block (version 16 needs kernel
- patches, will be fwd separately).
- String block now has a size, and full path
- is replaced by unit name for more
- compactness.
- linux,phandle is made optional, only nodes
- that are referenced by other nodes need it.
- "name" property is now automatically
- deduced from the unit name
-
- June 1, 2005: Rev 0.4 - Correct confusion between OF_DT_END and
- OF_DT_END_NODE in structure definition.
- - Change version 16 format to always align
- property data to 4 bytes. Since tokens are
- already aligned, that means no specific
- required alignment between property size
- and property data. The old style variable
- alignment would make it impossible to do
- "simple" insertion of properties using
- memmove (thanks Milton for
- noticing). Updated kernel patch as well
- - Correct a few more alignment constraints
- - Add a chapter about the device-tree
- compiler and the textural representation of

-
-I - Introduction
-================
-
-During the development of the Linux/ppc64 kernel, and more
-specifically, the addition of new platform types outside of the old
-IBM pSeries/iSeries pair, it was decided to enforce some strict rules
-regarding the kernel entry and bootloader <-> kernel interfaces, in
-order to avoid the degeneration that had become the ppc32 kernel entry
-point and the way a new platform should be added to the kernel. The
-legacy iSeries platform breaks those rules as it predates this scheme,
-but no new board support will be accepted in the main tree that
-doesn't follow them properly. In addition, since the advent of the
-arch/powerpc merged architecture for ppc32 and ppc64, new 32-bit
-platforms and 32-bit platforms which move into arch/powerpc will be
-required to use these rules as well.
-
-The main requirement that will be defined in more detail below is
-the presence of a device-tree whose format is defined after Open
-Firmware specification. However, in order to make life easier
-to embedded board vendors, the kernel doesn't require the device-tree
-to represent every device in the system and only requires some nodes
-and properties to be present. This will be described in detail in
-section III, but, for example, the kernel does not require you to
-create a node for every PCI device in the system. It is a requirement
-to have a node for PCI host bridges in order to provide interrupt
-routing information and memory/IO ranges, among others. It is also
-recommended to define nodes for on chip devices and other buses that
-don't specifically fit in an existing OF specification. This creates a
-great flexibility in the way the kernel can then probe those and match
-drivers to device, without having to hard code all sorts of tables. It
-also makes it more flexible for board vendors to do minor hardware
-upgrades without significantly impacting the kernel code or cluttering
-it with special cases.
-
-
-1) Entry point for arch/arm
----------------------------
-
- There is one single entry point to the kernel, at the start
- of the kernel image. That entry point supports two calling
- conventions. A summary of the interface is described here. A full
- description of the boot requirements is documented in
- Documentation/arm/booting.rst
-
- a) ATAGS interface. Minimal information is passed from firmware
- to the kernel with a tagged list of predefined parameters.
-
- r0 : 0
-
- r1 : Machine type number
-
- r2 : Physical address of tagged list in system RAM
-
- b) Entry with a flattened device-tree block. Firmware loads the
- physical address of the flattened device tree block (dtb) into r2,
- r1 is not used, but it is considered good practice to use a valid
- machine number as described in Documentation/arm/booting.rst.
-
- r0 : 0
-
- r1 : Valid machine type number. When using a device tree,
- a single machine type number will often be assigned to
- represent a class or family of SoCs.
-
- r2 : physical pointer to the device-tree block
- (defined in chapter II) in RAM. Device tree can be located
- anywhere in system RAM, but it should be aligned on a 64 bit
- boundary.
-
- The kernel will differentiate between ATAGS and device tree booting by
- reading the memory pointed to by r2 and looking for either the flattened
- device tree block magic value (0xd00dfeed) or the ATAG_CORE value at
- offset 0x4 from r2 (0x54410001).
-
-2) Entry point for arch/powerpc
--------------------------------
-
- There is one single entry point to the kernel, at the start
- of the kernel image. That entry point supports two calling
- conventions:
-
- a) Boot from Open Firmware. If your firmware is compatible
- with Open Firmware (IEEE 1275) or provides an OF compatible
- client interface API (support for "interpret" callback of
- forth words isn't required), you can enter the kernel with:
-
- r5 : OF callback pointer as defined by IEEE 1275
- bindings to powerpc. Only the 32-bit client interface
- is currently supported
-
- r3, r4 : address & length of an initrd if any or 0
-
- The MMU is either on or off; the kernel will run the
- trampoline located in arch/powerpc/kernel/prom_init.c to
- extract the device-tree and other information from open
- firmware and build a flattened device-tree as described
- in b). prom_init() will then re-enter the kernel using
- the second method. This trampoline code runs in the
- context of the firmware, which is supposed to handle all
- exceptions during that time.
-
- b) Direct entry with a flattened device-tree block. This entry
- point is called by a) after the OF trampoline and can also be
- called directly by a bootloader that does not support the Open
- Firmware client interface. It is also used by "kexec" to
- implement "hot" booting of a new kernel from a previous
- running one. This method is what I will describe in more
- details in this document, as method a) is simply standard Open
- Firmware, and thus should be implemented according to the
- various standard documents defining it and its binding to the
- PowerPC platform. The entry point definition then becomes:
-
- r3 : physical pointer to the device-tree block
- (defined in chapter II) in RAM
-
- r4 : physical pointer to the kernel itself. This is
- used by the assembly code to properly disable the MMU
- in case you are entering the kernel with MMU enabled
- and a non-1:1 mapping.
-
- r5 : NULL (as to differentiate with method a)
-
- Note about SMP entry: Either your firmware puts your other
- CPUs in some sleep loop or spin loop in ROM where you can get
- them out via a soft reset or some other means, in which case
- you don't need to care, or you'll have to enter the kernel
- with all CPUs. The way to do that with method b) will be
- described in a later revision of this document.
-
- Board supports (platforms) are not exclusive config options. An
- arbitrary set of board supports can be built in a single kernel
- image. The kernel will "know" what set of functions to use for a
- given platform based on the content of the device-tree. Thus, you
- should:
-
- a) add your platform support as a _boolean_ option in
- arch/powerpc/Kconfig, following the example of PPC_PSERIES,
- PPC_PMAC and PPC_MAPLE. The later is probably a good
- example of a board support to start from.
-
- b) create your main platform file as
- "arch/powerpc/platforms/myplatform/myboard_setup.c" and add it
- to the Makefile under the condition of your CONFIG_
- option. This file will define a structure of type "ppc_md"
- containing the various callbacks that the generic code will
- use to get to your platform specific code
-
- A kernel image may support multiple platforms, but only if the
- platforms feature the same core architecture. A single kernel build
- cannot support both configurations with Book E and configurations
- with classic Powerpc architectures.
-
-3) Entry point for arch/x86
--------------------------------
-
- There is one single 32bit entry point to the kernel at code32_start,
- the decompressor (the real mode entry point goes to the same 32bit
- entry point once it switched into protected mode). That entry point
- supports one calling convention which is documented in
- Documentation/x86/boot.rst
- The physical pointer to the device-tree block (defined in chapter II)
- is passed via setup_data which requires at least boot protocol 2.09.
- The type filed is defined as
-
- #define SETUP_DTB 2
-
- This device-tree is used as an extension to the "boot page". As such it
- does not parse / consider data which is already covered by the boot
- page. This includes memory size, reserved ranges, command line arguments
- or initrd address. It simply holds information which can not be retrieved
- otherwise like interrupt routing or a list of devices behind an I2C bus.
-
-4) Entry point for arch/mips/bmips
-----------------------------------
-
- Some bootloaders only support a single entry point, at the start of the
- kernel image. Other bootloaders will jump to the ELF start address.
- Both schemes are supported; CONFIG_BOOT_RAW=y and CONFIG_NO_EXCEPT_FILL=y,
- so the first instruction immediately jumps to kernel_entry().
-
- Similar to the arch/arm case (b), a DT-aware bootloader is expected to
- set up the following registers:
-
- a0 : 0
-
- a1 : 0xffffffff
-
- a2 : Physical pointer to the device tree block (defined in chapter
- II) in RAM. The device tree can be located anywhere in the first
- 512MB of the physical address space (0x00000000 - 0x1fffffff),
- aligned on a 64 bit boundary.
-
- Legacy bootloaders do not use this convention, and they do not pass in a
- DT block. In this case, Linux will look for a builtin DTB, selected via
- CONFIG_DT_*.
-
- This convention is defined for 32-bit systems only, as there are not
- currently any 64-bit BMIPS implementations.
-
-5) Entry point for arch/sh
---------------------------
-
- Device-tree-compatible SH bootloaders are expected to provide the physical
- address of the device tree blob in r4. Since legacy bootloaders did not
- guarantee any particular initial register state, kernels built to
- inter-operate with old bootloaders must either use a builtin DTB or
- select a legacy board option (something other than CONFIG_SH_DEVICE_TREE)
- that does not use device tree. Support for the latter is being phased out
- in favor of device tree.
-
-
-II - The DT block format
-========================
-
-
-This chapter defines the actual format of the flattened device-tree
-passed to the kernel. The actual content of it and kernel requirements
-are described later. You can find example of code manipulating that
-format in various places, including arch/powerpc/kernel/prom_init.c
-which will generate a flattened device-tree from the Open Firmware
-representation, or the fs2dt utility which is part of the kexec tools
-which will generate one from a filesystem representation. It is
-expected that a bootloader like uboot provides a bit more support,
-that will be discussed later as well.
-
-Note: The block has to be in main memory. It has to be accessible in
-both real mode and virtual mode with no mapping other than main
-memory. If you are writing a simple flash bootloader, it should copy
-the block to RAM before passing it to the kernel.
-
-
-1) Header
----------
-
- The kernel is passed the physical address pointing to an area of memory
- that is roughly described in include/linux/of_fdt.h by the structure
- boot_param_header:
-
-struct boot_param_header {
- u32 magic; /* magic word OF_DT_HEADER */
- u32 totalsize; /* total size of DT block */
- u32 off_dt_struct; /* offset to structure */
- u32 off_dt_strings; /* offset to strings */
- u32 off_mem_rsvmap; /* offset to memory reserve map
- */
- u32 version; /* format version */
- u32 last_comp_version; /* last compatible version */
-
- /* version 2 fields below */
- u32 boot_cpuid_phys; /* Which physical CPU id we're
- booting on */
- /* version 3 fields below */
- u32 size_dt_strings; /* size of the strings block */
-
- /* version 17 fields below */
- u32 size_dt_struct; /* size of the DT structure block */
-};
-
- Along with the constants:
-
-/* Definitions used by the flattened device tree */
-#define OF_DT_HEADER 0xd00dfeed /* 4: version,
- 4: total size */
-#define OF_DT_BEGIN_NODE 0x1 /* Start node: full name
- */
-#define OF_DT_END_NODE 0x2 /* End node */
-#define OF_DT_PROP 0x3 /* Property: name off,
- size, content */
-#define OF_DT_END 0x9
-
- All values in this header are in big endian format, the various
- fields in this header are defined more precisely below. All
- "offset" values are in bytes from the start of the header; that is
- from the physical base address of the device tree block.
-
- - magic
-
- This is a magic value that "marks" the beginning of the
- device-tree block header. It contains the value 0xd00dfeed and is
- defined by the constant OF_DT_HEADER
-
- - totalsize
-
- This is the total size of the DT block including the header. The
- "DT" block should enclose all data structures defined in this
- chapter (who are pointed to by offsets in this header). That is,
- the device-tree structure, strings, and the memory reserve map.
-
- - off_dt_struct
-
- This is an offset from the beginning of the header to the start
- of the "structure" part the device tree. (see 2) device tree)
-
- - off_dt_strings
-
- This is an offset from the beginning of the header to the start
- of the "strings" part of the device-tree
-
- - off_mem_rsvmap
-
- This is an offset from the beginning of the header to the start
- of the reserved memory map. This map is a list of pairs of 64-
- bit integers. Each pair is a physical address and a size. The
- list is terminated by an entry of size 0. This map provides the
- kernel with a list of physical memory areas that are "reserved"
- and thus not to be used for memory allocations, especially during
- early initialization. The kernel needs to allocate memory during
- boot for things like un-flattening the device-tree, allocating an
- MMU hash table, etc... Those allocations must be done in such a
- way to avoid overriding critical things like, on Open Firmware
- capable machines, the RTAS instance, or on some pSeries, the TCE
- tables used for the iommu. Typically, the reserve map should
- contain _at least_ this DT block itself (header,total_size). If
- you are passing an initrd to the kernel, you should reserve it as
- well. You do not need to reserve the kernel image itself. The map
- should be 64-bit aligned.
-
- - version
-
- This is the version of this structure. Version 1 stops
- here. Version 2 adds an additional field boot_cpuid_phys.
- Version 3 adds the size of the strings block, allowing the kernel
- to reallocate it easily at boot and free up the unused flattened
- structure after expansion. Version 16 introduces a new more
- "compact" format for the tree itself that is however not backward
- compatible. Version 17 adds an additional field, size_dt_struct,
- allowing it to be reallocated or moved more easily (this is
- particularly useful for bootloaders which need to make
- adjustments to a device tree based on probed information). You
- should always generate a structure of the highest version defined
- at the time of your implementation. Currently that is version 17,
- unless you explicitly aim at being backward compatible.
-
- - last_comp_version
-
- Last compatible version. This indicates down to what version of
- the DT block you are backward compatible. For example, version 2
- is backward compatible with version 1 (that is, a kernel build
- for version 1 will be able to boot with a version 2 format). You
- should put a 1 in this field if you generate a device tree of
- version 1 to 3, or 16 if you generate a tree of version 16 or 17
- using the new unit name format.
-
- - boot_cpuid_phys
-
- This field only exist on version 2 headers. It indicate which
- physical CPU ID is calling the kernel entry point. This is used,
- among others, by kexec. If you are on an SMP system, this value
- should match the content of the "reg" property of the CPU node in
- the device-tree corresponding to the CPU calling the kernel entry
- point (see further chapters for more information on the required
- device-tree contents)
-
- - size_dt_strings
-
- This field only exists on version 3 and later headers. It
- gives the size of the "strings" section of the device tree (which
- starts at the offset given by off_dt_strings).
-
- - size_dt_struct
-
- This field only exists on version 17 and later headers. It gives
- the size of the "structure" section of the device tree (which
- starts at the offset given by off_dt_struct).
-
- So the typical layout of a DT block (though the various parts don't
- need to be in that order) looks like this (addresses go from top to
- bottom):
-
-
- ------------------------------
- base -> | struct boot_param_header |
- ------------------------------
- | (alignment gap) (*) |
- ------------------------------
- | memory reserve map |
- ------------------------------
- | (alignment gap) |

- -----> ------------------------------
- |
- |
- --- (base + totalsize)
-
- (*) The alignment gaps are not necessarily present; their presence
- and size are dependent on the various alignment requirements of
- the individual data blocks.
-
-
-2) Device tree generalities
----------------------------
-
-This device-tree itself is separated in two different blocks, a
-structure block and a strings block. Both need to be aligned to a 4
-byte boundary.
-
-First, let's quickly describe the device-tree concept before detailing
-the storage format. This chapter does _not_ describe the detail of the
-required types of nodes & properties for the kernel, this is done
-later in chapter III.
-
-The device-tree layout is strongly inherited from the definition of
-the Open Firmware IEEE 1275 device-tree. It's basically a tree of
-nodes, each node having two or more named properties. A property can
-have a value or not.
-
-It is a tree, so each node has one and only one parent except for the
-root node who has no parent.
-
-A node has 2 names. The actual node name is generally contained in a
-property of type "name" in the node property list whose value is a
-zero terminated string and is mandatory for version 1 to 3 of the
-format definition (as it is in Open Firmware). Version 16 makes it
-optional as it can generate it from the unit name defined below.
-
-There is also a "unit name" that is used to differentiate nodes with
-the same name at the same level, it is usually made of the node
-names, the "@" sign, and a "unit address", which definition is
-specific to the bus type the node sits on.
-
-The unit name doesn't exist as a property per-se but is included in
-the device-tree structure. It is typically used to represent "path" in
-the device-tree. More details about the actual format of these will be
-below.
-
-The kernel generic code does not make any formal use of the
-unit address (though some board support code may do) so the only real
-requirement here for the unit address is to ensure uniqueness of
-the node unit name at a given level of the tree. Nodes with no notion
-of address and no possible sibling of the same name (like /memory or
-/cpus) may omit the unit address in the context of this specification,
-or use the "@0" default unit address. The unit name is used to define
-a node "full path", which is the concatenation of all parent node
-unit names separated with "/".
-
-The root node doesn't have a defined name, and isn't required to have
-a name property either if you are using version 3 or earlier of the
-format. It also has no unit address (no @ symbol followed by a unit
-address). The root node unit name is thus an empty string. The full
-path to the root node is "/".
-
-Every node which actually represents an actual device (that is, a node
-which isn't only a virtual "container" for more nodes, like "/cpus"
-is) is also required to have a "compatible" property indicating the
-specific hardware and an optional list of devices it is fully
-backwards compatible with.
-
-Finally, every node that can be referenced from a property in another
-node is required to have either a "phandle" or a "linux,phandle"
-property. Real Open Firmware implementations provide a unique
-"phandle" value for every node that the "prom_init()" trampoline code
-turns into "linux,phandle" properties. However, this is made optional
-if the flattened device tree is used directly. An example of a node
-referencing another node via "phandle" is when laying out the
-interrupt tree which will be described in a further version of this
-document.
-
-The "phandle" property is a 32-bit value that uniquely
-identifies a node. You are free to use whatever values or system of
-values, internal pointers, or whatever to generate these, the only
-requirement is that every node for which you provide that property has
-a unique value for it.
-
-Here is an example of a simple device-tree. In this example, an "o"
-designates a node followed by the node unit name. Properties are
-presented with their name followed by their content. "content"
-represents an ASCII string (zero terminated) value, while <content>
-represents a 32-bit value, specified in decimal or hexadecimal (the
-latter prefixed 0x). The various nodes in this example will be
-discussed in a later chapter. At this point, it is only meant to give
-you a idea of what a device-tree looks like. I have purposefully kept
-the "name" and "linux,phandle" properties which aren't necessary in
-order to give you a better idea of what the tree looks like in
-practice.
-
- / o device-tree
- |- name = "device-tree"
- |- model = "MyBoardName"
- |- compatible = "MyBoardFamilyName"
- |- #address-cells = <2>
- |- #size-cells = <2>
- |- linux,phandle = <0>
- |
- o cpus
- | | - name = "cpus"
- | | - linux,phandle = <1>
- | | - #address-cells = <1>
- | | - #size-cells = <0>
- | |
- | o PowerPC,970@0
- | |- name = "PowerPC,970"
- | |- device_type = "cpu"
- | |- reg = <0>
- | |- clock-frequency = <0x5f5e1000>
- | |- 64-bit
- | |- linux,phandle = <2>
- |
- o memory@0
- | |- name = "memory"
- | |- device_type = "memory"
- | |- reg = <0x00000000 0x00000000 0x00000000 0x20000000>
- | |- linux,phandle = <3>
- |
- o chosen
- |- name = "chosen"
- |- bootargs = "root=/dev/sda2"
- |- linux,phandle = <4>
-
-This tree is almost a minimal tree. It pretty much contains the
-minimal set of required nodes and properties to boot a linux kernel;
-that is, some basic model information at the root, the CPUs, and the
-physical memory layout. It also includes misc information passed
-through /chosen, like in this example, the platform type (mandatory)
-and the kernel command line arguments (optional).
-
-The /cpus/PowerPC,970@0/64-bit property is an example of a
-property without a value. All other properties have a value. The
-significance of the #address-cells and #size-cells properties will be
-explained in chapter IV which defines precisely the required nodes and
-properties and their content.
-
-
-3) Device tree "structure" block
-
-The structure of the device tree is a linearized tree structure. The
-"OF_DT_BEGIN_NODE" token starts a new node, and the "OF_DT_END_NODE"
-ends that node definition. Child nodes are simply defined before
-"OF_DT_END_NODE" (that is nodes within the node). A 'token' is a 32
-bit value. The tree has to be "finished" with a OF_DT_END token
-
-Here's the basic structure of a single node:
-
- * token OF_DT_BEGIN_NODE (that is 0x00000001)
- * for version 1 to 3, this is the node full path as a zero
- terminated string, starting with "/". For version 16 and later,
- this is the node unit name only (or an empty string for the
- root node)
- * [align gap to next 4 bytes boundary]
- * for each property:
- * token OF_DT_PROP (that is 0x00000003)
- * 32-bit value of property value size in bytes (or 0 if no
- value)
- * 32-bit value of offset in string block of property name
- * property value data if any
- * [align gap to next 4 bytes boundary]
- * [child nodes if any]
- * token OF_DT_END_NODE (that is 0x00000002)
-
-So the node content can be summarized as a start token, a full path,
-a list of properties, a list of child nodes, and an end token. Every
-child node is a full node structure itself as defined above.
-
-NOTE: The above definition requires that all property definitions for
-a particular node MUST precede any subnode definitions for that node.
-Although the structure would not be ambiguous if properties and
-subnodes were intermingled, the kernel parser requires that the
-properties come first (up until at least 2.6.22). Any tools
-manipulating a flattened tree must take care to preserve this
-constraint.
-
-4) Device tree "strings" block
-
-In order to save space, property names, which are generally redundant,
-are stored separately in the "strings" block. This block is simply the
-whole bunch of zero terminated strings for all property names
-concatenated together. The device-tree property definitions in the
-structure block will contain offset values from the beginning of the
-strings block.
-
-
-III - Required content of the device tree
-=========================================
-
-WARNING: All "linux,*" properties defined in this document apply only
-to a flattened device-tree. If your platform uses a real
-implementation of Open Firmware or an implementation compatible with
-the Open Firmware client interface, those properties will be created
-by the trampoline code in the kernel's prom_init() file. For example,
-that's where you'll have to add code to detect your board model and
-set the platform number. However, when using the flattened device-tree
-entry point, there is no prom_init() pass, and thus you have to
-provide those properties yourself.
-
-
-1) Note about cells and address representation
-----------------------------------------------
-
-The general rule is documented in the various Open Firmware
-documentations. If you choose to describe a bus with the device-tree
-and there exist an OF bus binding, then you should follow the
-specification. However, the kernel does not require every single
-device or bus to be described by the device tree.
-
-In general, the format of an address for a device is defined by the
-parent bus type, based on the #address-cells and #size-cells
-properties. Note that the parent's parent definitions of #address-cells
-and #size-cells are not inherited so every node with children must specify
-them. The kernel requires the root node to have those properties defining
-addresses format for devices directly mapped on the processor bus.
-
-Those 2 properties define 'cells' for representing an address and a
-size. A "cell" is a 32-bit number. For example, if both contain 2
-like the example tree given above, then an address and a size are both
-composed of 2 cells, and each is a 64-bit number (cells are
-concatenated and expected to be in big endian format). Another example
-is the way Apple firmware defines them, with 2 cells for an address
-and one cell for a size. Most 32-bit implementations should define
-#address-cells and #size-cells to 1, which represents a 32-bit value.
-Some 32-bit processors allow for physical addresses greater than 32
-bits; these processors should define #address-cells as 2.
-
-"reg" properties are always a tuple of the type "address size" where
-the number of cells of address and size is specified by the bus
-#address-cells and #size-cells. When a bus supports various address
-spaces and other flags relative to a given address allocation (like
-prefetchable, etc...) those flags are usually added to the top level
-bits of the physical address. For example, a PCI physical address is
-made of 3 cells, the bottom two containing the actual address itself
-while the top cell contains address space indication, flags, and pci
-bus & device numbers.
-
-For buses that support dynamic allocation, it's the accepted practice
-to then not provide the address in "reg" (keep it 0) though while
-providing a flag indicating the address is dynamically allocated, and
-then, to provide a separate "assigned-addresses" property that
-contains the fully allocated addresses. See the PCI OF bindings for
-details.
-
-In general, a simple bus with no address space bits and no dynamic
-allocation is preferred if it reflects your hardware, as the existing
-kernel address parsing functions will work out of the box. If you
-define a bus type with a more complex address format, including things
-like address space bits, you'll have to add a bus translator to the
-prom_parse.c file of the recent kernels for your bus type.
-
-The "reg" property only defines addresses and sizes (if #size-cells is
-non-0) within a given bus. In order to translate addresses upward
-(that is into parent bus addresses, and possibly into CPU physical
-addresses), all buses must contain a "ranges" property. If the
-"ranges" property is missing at a given level, it's assumed that
-translation isn't possible, i.e., the registers are not visible on the
-parent bus. The format of the "ranges" property for a bus is a list
-of:
-
- bus address, parent bus address, size
-
-"bus address" is in the format of the bus this bus node is defining,
-that is, for a PCI bridge, it would be a PCI address. Thus, (bus
-address, size) defines a range of addresses for child devices. "parent
-bus address" is in the format of the parent bus of this bus. For
-example, for a PCI host controller, that would be a CPU address. For a
-PCI<->ISA bridge, that would be a PCI address. It defines the base
-address in the parent bus where the beginning of that range is mapped.
-
-For new 64-bit board support, I recommend either the 2/2 format or
-Apple's 2/1 format which is slightly more compact since sizes usually
-fit in a single 32-bit word. New 32-bit board support should use a
-1/1 format, unless the processor supports physical addresses greater
-than 32-bits, in which case a 2/1 format is recommended.
-
-Alternatively, the "ranges" property may be empty, indicating that the
-registers are visible on the parent bus using an identity mapping
-translation. In other words, the parent bus address space is the same
-as the child bus address space.
-
-2) Note about "compatible" properties
--------------------------------------
-
-These properties are optional, but recommended in devices and the root
-node. The format of a "compatible" property is a list of concatenated
-zero terminated strings. They allow a device to express its
-compatibility with a family of similar devices, in some cases,
-allowing a single driver to match against several devices regardless
-of their actual names.
-
-3) Note about "name" properties
--------------------------------
-
-While earlier users of Open Firmware like OldWorld macintoshes tended
-to use the actual device name for the "name" property, it's nowadays
-considered a good practice to use a name that is closer to the device
-class (often equal to device_type). For example, nowadays, Ethernet
-controllers are named "ethernet", an additional "model" property
-defining precisely the chip type/model, and "compatible" property
-defining the family in case a single driver can driver more than one
-of these chips. However, the kernel doesn't generally put any
-restriction on the "name" property; it is simply considered good
-practice to follow the standard and its evolutions as closely as
-possible.
-
-Note also that the new format version 16 makes the "name" property
-optional. If it's absent for a node, then the node's unit name is then
-used to reconstruct the name. That is, the part of the unit name
-before the "@" sign is used (or the entire unit name if no "@" sign
-is present).
-
-4) Note about node and property names and character set
--------------------------------------------------------
-
-While Open Firmware provides more flexible usage of 8859-1, this
-specification enforces more strict rules. Nodes and properties should
-be comprised only of ASCII characters 'a' to 'z', '0' to
-'9', ',', '.', '_', '+', '#', '?', and '-'. Node names additionally
-allow uppercase characters 'A' to 'Z' (property names should be
-lowercase. The fact that vendors like Apple don't respect this rule is
-irrelevant here). Additionally, node and property names should always
-begin with a character in the range 'a' to 'z' (or 'A' to 'Z' for node
-names).
-
-The maximum number of characters for both nodes and property names
-is 31. In the case of node names, this is only the leftmost part of
-a unit name (the pure "name" property), it doesn't include the unit
-address which can extend beyond that limit.
-
-
-5) Required nodes and properties
---------------------------------
- These are all that are currently required. However, it is strongly
- recommended that you expose PCI host bridges as documented in the
- PCI binding to Open Firmware, and your interrupt tree as documented
- in OF interrupt tree specification.
-
- a) The root node
-
- The root node requires some properties to be present:
-
- - model : this is your board name/model
- - #address-cells : address representation for "root" devices
- - #size-cells: the size representation for "root" devices
- - compatible : the board "family" generally finds its way here,
- for example, if you have 2 board models with a similar layout,
- that typically get driven by the same platform code in the
- kernel, you would specify the exact board model in the
- compatible property followed by an entry that represents the SoC
- model.
-
- The root node is also generally where you add additional properties
- specific to your board like the serial number if any, that sort of
- thing. It is recommended that if you add any "custom" property whose
- name may clash with standard defined ones, you prefix them with your
- vendor name and a comma.
-
- Additional properties for the root node:
-
- - serial-number : a string representing the device's serial number
-
- b) The /cpus node
-
- This node is the parent of all individual CPU nodes. It doesn't
- have any specific requirements, though it's generally good practice
- to have at least:
-
- #address-cells = <00000001>
- #size-cells = <00000000>
-
- This defines that the "address" for a CPU is a single cell, and has
- no meaningful size. This is not necessary but the kernel will assume
- that format when reading the "reg" properties of a CPU node, see
- below
-
- c) The /cpus/* nodes
-
- So under /cpus, you are supposed to create a node for every CPU on
- the machine. There is no specific restriction on the name of the
- CPU, though it's common to call it <architecture>,<core>. For
- example, Apple uses PowerPC,G5 while IBM uses PowerPC,970FX.
- However, the Generic Names convention suggests that it would be
- better to simply use 'cpu' for each cpu node and use the compatible
- property to identify the specific cpu core.
-
- Required properties:
-
- - device_type : has to be "cpu"
- - reg : This is the physical CPU number, it's a single 32-bit cell
- and is also used as-is as the unit number for constructing the
- unit name in the full path. For example, with 2 CPUs, you would
- have the full path:
- /cpus/PowerPC,970FX@0
- /cpus/PowerPC,970FX@1
- (unit addresses do not require leading zeroes)
- - d-cache-block-size : one cell, L1 data cache block size in bytes (*)
- - i-cache-block-size : one cell, L1 instruction cache block size in
- bytes
- - d-cache-size : one cell, size of L1 data cache in bytes
- - i-cache-size : one cell, size of L1 instruction cache in bytes
-
-(*) The cache "block" size is the size on which the cache management
-instructions operate. Historically, this document used the cache
-"line" size here which is incorrect. The kernel will prefer the cache
-block size and will fallback to cache line size for backward
-compatibility.
-
- Recommended properties:
-
- - timebase-frequency : a cell indicating the frequency of the
- timebase in Hz. This is not directly used by the generic code,
- but you are welcome to copy/paste the pSeries code for setting
- the kernel timebase/decrementer calibration based on this
- value.
- - clock-frequency : a cell indicating the CPU core clock frequency
- in Hz. A new property will be defined for 64-bit values, but if
- your frequency is < 4Ghz, one cell is enough. Here as well as
- for the above, the common code doesn't use that property, but
- you are welcome to re-use the pSeries or Maple one. A future
- kernel version might provide a common function for this.
- - d-cache-line-size : one cell, L1 data cache line size in bytes
- if different from the block size
- - i-cache-line-size : one cell, L1 instruction cache line size in
- bytes if different from the block size
-
- You are welcome to add any property you find relevant to your board,
- like some information about the mechanism used to soft-reset the
- CPUs. For example, Apple puts the GPIO number for CPU soft reset
- lines in there as a "soft-reset" property since they start secondary
- CPUs by soft-resetting them.
-
-
- d) the /memory node(s)
-
- To define the physical memory layout of your board, you should
- create one or more memory node(s). You can either create a single
- node with all memory ranges in its reg property, or you can create
- several nodes, as you wish. The unit address (@ part) used for the
- full path is the address of the first range of memory defined by a
- given node. If you use a single memory node, this will typically be
- @0.
-
- Required properties:
-
- - device_type : has to be "memory"
- - reg : This property contains all the physical memory ranges of
- your board. It's a list of addresses/sizes concatenated
- together, with the number of cells of each defined by the
- #address-cells and #size-cells of the root node. For example,
- with both of these properties being 2 like in the example given
- earlier, a 970 based machine with 6Gb of RAM could typically
- have a "reg" property here that looks like:
-
- 00000000 00000000 00000000 80000000
- 00000001 00000000 00000001 00000000
-
- That is a range starting at 0 of 0x80000000 bytes and a range
- starting at 0x100000000 and of 0x100000000 bytes. You can see
- that there is no memory covering the IO hole between 2Gb and
- 4Gb. Some vendors prefer splitting those ranges into smaller
- segments, but the kernel doesn't care.
-
- Additional properties:
-
- - hotpluggable : The presence of this property provides an explicit
- hint to the operating system that this memory may potentially be
- removed later. The kernel can take this into consideration when
- doing nonmovable allocations and when laying out memory zones.
-
- e) The /chosen node
-
- This node is a bit "special". Normally, that's where Open Firmware
- puts some variable environment information, like the arguments, or
- the default input/output devices.
-
- This specification makes a few of these mandatory, but also defines
- some linux-specific properties that would be normally constructed by
- the prom_init() trampoline when booting with an OF client interface,
- but that you have to provide yourself when using the flattened format.
-
- Recommended properties:
-
- - bootargs : This zero-terminated string is passed as the kernel
- command line
- - linux,stdout-path : This is the full path to your standard
- console device if any. Typically, if you have serial devices on
- your board, you may want to put the full path to the one set as
- the default console in the firmware here, for the kernel to pick
- it up as its own default console.
-
- Note that u-boot creates and fills in the chosen node for platforms
- that use it.
-
- (Note: a practice that is now obsolete was to include a property
- under /chosen called interrupt-controller which had a phandle value
- that pointed to the main interrupt controller)
-
- f) the /soc<SOCname> node
-
- This node is used to represent a system-on-a-chip (SoC) and must be
- present if the processor is a SoC. The top-level soc node contains
- information that is global to all devices on the SoC. The node name
- should contain a unit address for the SoC, which is the base address
- of the memory-mapped register set for the SoC. The name of an SoC
- node should start with "soc", and the remainder of the name should
- represent the part number for the soc. For example, the MPC8540's
- soc node would be called "soc8540".
-
- Required properties:
-
- - ranges : Should be defined as specified in 1) to describe the
- translation of SoC addresses for memory mapped SoC registers.
- - bus-frequency: Contains the bus frequency for the SoC node.
- Typically, the value of this field is filled in by the boot
- loader.
- - compatible : Exact model of the SoC
-
-
- Recommended properties:
-
- - reg : This property defines the address and size of the
- memory-mapped registers that are used for the SOC node itself.
- It does not include the child device registers - these will be
- defined inside each child node. The address specified in the
- "reg" property should match the unit address of the SOC node.
- - #address-cells : Address representation for "soc" devices. The
- format of this field may vary depending on whether or not the
- device registers are memory mapped. For memory mapped
- registers, this field represents the number of cells needed to
- represent the address of the registers. For SOCs that do not
- use MMIO, a special address format should be defined that
- contains enough cells to represent the required information.
- See 1) above for more details on defining #address-cells.
- - #size-cells : Size representation for "soc" devices
- - #interrupt-cells : Defines the width of cells used to represent
- interrupts. Typically this value is <2>, which includes a
- 32-bit number that represents the interrupt number, and a
- 32-bit number that represents the interrupt sense and level.
- This field is only needed if the SOC contains an interrupt
- controller.
-
- The SOC node may contain child nodes for each SOC device that the
- platform uses. Nodes should not be created for devices which exist
- on the SOC but are not used by a particular platform. See chapter VI
- for more information on how to specify devices that are part of a SOC.
-
- Example SOC node for the MPC8540:
-
- soc8540@e0000000 {
- #address-cells = <1>;
- #size-cells = <1>;
- #interrupt-cells = <2>;
- device_type = "soc";
- ranges = <0x00000000 0xe0000000 0x00100000>
- reg = <0xe0000000 0x00003000>;
- bus-frequency = <0>;
- }
-
-
-
-IV - "dtc", the device tree compiler
-====================================
-
-
-dtc source code can be found at
-<http://git.jdl.com/gitweb/?p=dtc.git>
-
-WARNING: This version is still in early development stage; the
-resulting device-tree "blobs" have not yet been validated with the
-kernel. The current generated block lacks a useful reserve map (it will
-be fixed to generate an empty one, it's up to the bootloader to fill
-it up) among others. The error handling needs work, bugs are lurking,
-etc...
-
-dtc basically takes a device-tree in a given format and outputs a
-device-tree in another format. The currently supported formats are:
-
- Input formats:
- -------------
-
- - "dtb": "blob" format, that is a flattened device-tree block
- with
- header all in a binary blob.
- - "dts": "source" format. This is a text file containing a
- "source" for a device-tree. The format is defined later in this
- chapter.
- - "fs" format. This is a representation equivalent to the
- output of /proc/device-tree, that is nodes are directories and
- properties are files
-
- Output formats:
- ---------------
-
- - "dtb": "blob" format
- - "dts": "source" format
- - "asm": assembly language file. This is a file that can be
- sourced by gas to generate a device-tree "blob". That file can
- then simply be added to your Makefile. Additionally, the
- assembly file exports some symbols that can be used.
-
-
-The syntax of the dtc tool is
-
- dtc [-I <input-format>] [-O <output-format>]
- [-o output-filename] [-V output_version] input_filename
-
-
-The "output_version" defines what version of the "blob" format will be
-generated. Supported versions are 1,2,3 and 16. The default is
-currently version 3 but that may change in the future to version 16.
-
-Additionally, dtc performs various sanity checks on the tree, like the
-uniqueness of linux, phandle properties, validity of strings, etc...
-
-The format of the .dts "source" file is "C" like, supports C and C++
-style comments.
-
-/ {
-}
-
-The above is the "device-tree" definition. It's the only statement
-supported currently at the toplevel.
-
-/ {
- property1 = "string_value"; /* define a property containing a 0
- * terminated string
- */
-
- property2 = <0x1234abcd>; /* define a property containing a
- * numerical 32-bit value (hexadecimal)
- */
-
- property3 = <0x12345678 0x12345678 0xdeadbeef>;
- /* define a property containing 3
- * numerical 32-bit values (cells) in
- * hexadecimal
- */
- property4 = [0x0a 0x0b 0x0c 0x0d 0xde 0xea 0xad 0xbe 0xef];
- /* define a property whose content is
- * an arbitrary array of bytes
- */
-
- childnode@address { /* define a child node named "childnode"
- * whose unit name is "childnode at
- * address"
- */
-
- childprop = "hello\n"; /* define a property "childprop" of
- * childnode (in this case, a string)
- */
- };
-};
-
-Nodes can contain other nodes etc... thus defining the hierarchical
-structure of the tree.
-
-Strings support common escape sequences from C: "\n", "\t", "\r",
-"\(octal value)", "\x(hex value)".
-
-It is also suggested that you pipe your source file through cpp (gcc
-preprocessor) so you can use #include's, #define for constants, etc...
-
-Finally, various options are planned but not yet implemented, like
-automatic generation of phandles, labels (exported to the asm file so
-you can point to a property content and change it easily from whatever
-you link the device-tree with), label or path instead of numeric value
-in some cells to "point" to a node (replaced by a phandle at compile
-time), export of reserve map address to the asm file, ability to
-specify reserve map content at compile time, etc...
-
-We may provide a .h include file with common definitions of that
-proves useful for some properties (like building PCI properties or
-interrupt maps) though it may be better to add a notion of struct
-definitions to the compiler...
-
-
-V - Recommendations for a bootloader
-====================================
-
-
-Here are some various ideas/recommendations that have been proposed
-while all this has been defined and implemented.
-
- - The bootloader may want to be able to use the device-tree itself
- and may want to manipulate it (to add/edit some properties,
- like physical memory size or kernel arguments). At this point, 2
- choices can be made. Either the bootloader works directly on the
- flattened format, or the bootloader has its own internal tree
- representation with pointers (similar to the kernel one) and
- re-flattens the tree when booting the kernel. The former is a bit
- more difficult to edit/modify, the later requires probably a bit
- more code to handle the tree structure. Note that the structure
- format has been designed so it's relatively easy to "insert"
- properties or nodes or delete them by just memmoving things
- around. It contains no internal offsets or pointers for this
- purpose.
-
- - An example of code for iterating nodes & retrieving properties
- directly from the flattened tree format can be found in the kernel
- file drivers/of/fdt.c. Look at the of_scan_flat_dt() function,
- its usage in early_init_devtree(), and the corresponding various
- early_init_dt_scan_*() callbacks. That code can be re-used in a
- GPL bootloader, and as the author of that code, I would be happy
- to discuss possible free licensing to any vendor who wishes to
- integrate all or part of this code into a non-GPL bootloader.
- (reference needed; who is 'I' here? ---gcl Jan 31, 2011)
-
-
-
-VI - System-on-a-chip devices and nodes
-=======================================
-
-Many companies are now starting to develop system-on-a-chip
-processors, where the processor core (CPU) and many peripheral devices
-exist on a single piece of silicon. For these SOCs, an SOC node
-should be used that defines child nodes for the devices that make
-up the SOC. While platforms are not required to use this model in
-order to boot the kernel, it is highly encouraged that all SOC
-implementations define as complete a flat-device-tree as possible to
-describe the devices on the SOC. This will allow for the
-genericization of much of the kernel code.
-
-
-1) Defining child nodes of an SOC
----------------------------------
-
-Each device that is part of an SOC may have its own node entry inside
-the SOC node. For each device that is included in the SOC, the unit
-address property represents the address offset for this device's
-memory-mapped registers in the parent's address space. The parent's
-address space is defined by the "ranges" property in the top-level soc
-node. The "reg" property for each node that exists directly under the
-SOC node should contain the address mapping from the child address space
-to the parent SOC address space and the size of the device's
-memory-mapped register file.
-
-For many devices that may exist inside an SOC, there are predefined
-specifications for the format of the device tree node. All SOC child
-nodes should follow these specifications, except where noted in this
-document.
-
-See appendix A for an example partial SOC node definition for the
-MPC8540.
-
-
-2) Representing devices without a current OF specification
-----------------------------------------------------------
-
-Currently, there are many devices on SoCs that do not have a standard
-representation defined as part of the Open Firmware specifications,
-mainly because the boards that contain these SoCs are not currently
-booted using Open Firmware. Binding documentation for new devices
-should be added to the Documentation/devicetree/bindings directory.
-That directory will expand as device tree support is added to more and
-more SoCs.
-
-
-VII - Specifying interrupt information for devices
-===================================================
-
-The device tree represents the buses and devices of a hardware
-system in a form similar to the physical bus topology of the
-hardware.
-
-In addition, a logical 'interrupt tree' exists which represents the
-hierarchy and routing of interrupts in the hardware.
-
-The interrupt tree model is fully described in the
-document "Open Firmware Recommended Practice: Interrupt
-Mapping Version 0.9". The document is available at:
-<http://www.devicetree.org/open-firmware/practice/>
-
-1) interrupts property
-----------------------
-
-Devices that generate interrupts to a single interrupt controller
-should use the conventional OF representation described in the
-OF interrupt mapping documentation.
-
-Each device which generates interrupts must have an 'interrupt'
-property. The interrupt property value is an arbitrary number of
-of 'interrupt specifier' values which describe the interrupt or
-interrupts for the device.
-
-The encoding of an interrupt specifier is determined by the
-interrupt domain in which the device is located in the
-interrupt tree. The root of an interrupt domain specifies in
-its #interrupt-cells property the number of 32-bit cells
-required to encode an interrupt specifier. See the OF interrupt
-mapping documentation for a detailed description of domains.
-
-For example, the binding for the OpenPIC interrupt controller
-specifies an #interrupt-cells value of 2 to encode the interrupt
-number and level/sense information. All interrupt children in an
-OpenPIC interrupt domain use 2 cells per interrupt in their interrupts
-property.
-
-The PCI bus binding specifies a #interrupt-cells value of 1 to encode
-which interrupt pin (INTA,INTB,INTC,INTD) is used.
-
-2) interrupt-parent property
-----------------------------
-
-The interrupt-parent property is specified to define an explicit
-link between a device node and its interrupt parent in
-the interrupt tree. The value of interrupt-parent is the
-phandle of the parent node.
-
-If the interrupt-parent property is not defined for a node, its
-interrupt parent is assumed to be an ancestor in the node's
-_device tree_ hierarchy.
-
-3) OpenPIC Interrupt Controllers
---------------------------------
-
-OpenPIC interrupt controllers require 2 cells to encode
-interrupt information. The first cell defines the interrupt
-number. The second cell defines the sense and level
-information.
-
-Sense and level information should be encoded as follows:
-
- 0 = low to high edge sensitive type enabled
- 1 = active low level sensitive type enabled
- 2 = active high level sensitive type enabled
- 3 = high to low edge sensitive type enabled
-
-4) ISA Interrupt Controllers
-----------------------------
-
-ISA PIC interrupt controllers require 2 cells to encode
-interrupt information. The first cell defines the interrupt
-number. The second cell defines the sense and level
-information.
-
-ISA PIC interrupt controllers should adhere to the ISA PIC
-encodings listed below:
-
- 0 = active low level sensitive type enabled
- 1 = active high level sensitive type enabled
- 2 = high to low edge sensitive type enabled
- 3 = low to high edge sensitive type enabled
-
-VIII - Specifying Device Power Management Information (sleep property)
-===================================================================
-
-Devices on SOCs often have mechanisms for placing devices into low-power
-states that are decoupled from the devices' own register blocks. Sometimes,
-this information is more complicated than a cell-index property can
-reasonably describe. Thus, each device controlled in such a manner
-may contain a "sleep" property which describes these connections.
-
-The sleep property consists of one or more sleep resources, each of
-which consists of a phandle to a sleep controller, followed by a
-controller-specific sleep specifier of zero or more cells.
-
-The semantics of what type of low power modes are possible are defined
-by the sleep controller. Some examples of the types of low power modes
-that may be supported are:
-
- - Dynamic: The device may be disabled or enabled at any time.
- - System Suspend: The device may request to be disabled or remain
- awake during system suspend, but will not be disabled until then.
- - Permanent: The device is disabled permanently (until the next hard
- reset).
-
-Some devices may share a clock domain with each other, such that they should
-only be suspended when none of the devices are in use. Where reasonable,
-such nodes should be placed on a virtual bus, where the bus has the sleep
-property. If the clock domain is shared among devices that cannot be
-reasonably grouped in this manner, then create a virtual sleep controller
-(similar to an interrupt nexus, except that defining a standardized
-sleep-map should wait until its necessity is demonstrated).
-
-IX - Specifying dma bus information
-
-Some devices may have DMA memory range shifted relatively to the beginning of
-RAM, or even placed outside of kernel RAM. For example, the Keystone 2 SoC
-worked in LPAE mode with 4G memory has:
-- RAM range: [0x8 0000 0000, 0x8 FFFF FFFF]
-- DMA range: [ 0x8000 0000, 0xFFFF FFFF]
-and DMA range is aliased into first 2G of RAM in HW.
-
-In such cases, DMA addresses translation should be performed between CPU phys
-and DMA addresses. The "dma-ranges" property is intended to be used
-for describing the configuration of such system in DT.
-
-In addition, each DMA master device on the DMA bus may or may not support
-coherent DMA operations. The "dma-coherent" property is intended to be used
-for identifying devices supported coherent DMA operations in DT.
-
-* DMA Bus master
-Optional property:
-- dma-ranges: <prop-encoded-array> encoded as arbitrary number of triplets of
- (child-bus-address, parent-bus-address, length). Each triplet specified
- describes a contiguous DMA address range.
- The dma-ranges property is used to describe the direct memory access (DMA)
- structure of a memory-mapped bus whose device tree parent can be accessed
- from DMA operations originating from the bus. It provides a means of
- defining a mapping or translation between the physical address space of
- the bus and the physical address space of the parent of the bus.
- (for more information see the Devicetree Specification)
-
-* DMA Bus child
-Optional property:
-- dma-ranges: <empty> value. if present - It means that DMA addresses
- translation has to be enabled for this device.
-- dma-coherent: Present if dma operations are coherent
-
-Example:
-soc {
- compatible = "ti,keystone","simple-bus";
- ranges = <0x0 0x0 0x0 0xc0000000>;
- dma-ranges = <0x80000000 0x8 0x00000000 0x80000000>;
-
- [...]
-
- usb: usb@2680000 {
- compatible = "ti,keystone-dwc3";
-
- [...]
- dma-coherent;
- };
-};

+DT Changesets
+=============
+
+A DT changeset is a method which allows one to apply changes
+in the live tree in such a way that either the full set of changes
+will be applied, or none of them will be. If an error occurs partway
+through applying the changeset, then the tree will be rolled back to the
+previous state. A changeset can also be removed after it has been
+applied.
+
+When a changeset is applied, all of the changes get applied to the tree
+at once before emitting OF_RECONFIG notifiers. This is so that the
+receiver sees a complete and consistent state of the tree when it
+receives the notifier.
+
+The sequence of a changeset is as follows.
+
+1. of_changeset_init() - initializes a changeset
+
+2. A number of DT tree change calls, of_changeset_attach_node(),
+ of_changeset_detach_node(), of_changeset_add_property(),
+ of_changeset_remove_property, of_changeset_update_property() to prepare
+ a set of changes. No changes to the active tree are made at this point.
+ All the change operations are recorded in the of_changeset 'entries'
+ list.
+
+3. of_changeset_apply() - Apply the changes to the tree. Either the
+ entire changeset will get applied, or if there is an error the tree will
+ be restored to the previous state. The core ensures proper serialization
+ through locking. An unlocked version __of_changeset_apply is available,
+ if needed.
+
+If a successfully applied changeset needs to be removed, it can be done
+with of_changeset_revert().

+===============

+is attached to the live tree dynamically, independent of the machine's
+architecture.
+
+It is recommended to read the following documents before moving ahead.
+
+(1) Documentation/devicetree/usage-model.rst
+(2) http://www.devicetree.org/Device_Tree_Usage
+
+OF Selftest has been designed to test the interface (include/linux/of.h)
+provided to device driver developers to fetch the device information..etc.
+from the unflattened device tree data structure. This interface is used by
+most of the device drivers in various use cases.
+
+
+2. Test-data
+============
+
+The Device Tree Source file (drivers/of/unittest-data/testcases.dts) contains
+the test data required for executing the unit tests automated in
+drivers/of/unittest.c. Currently, following Device Tree Source Include files
+(.dtsi) are included in testcases.dts::
+
+ drivers/of/unittest-data/tests-interrupts.dtsi
+ drivers/of/unittest-data/tests-platform.dtsi
+ drivers/of/unittest-data/tests-phandle.dtsi
+ drivers/of/unittest-data/tests-match.dtsi
+
+When the kernel is build with OF_SELFTEST enabled, then the following make
+rule::
+
+ $(obj)/%.dtb: $(src)/%.dts FORCE
+ $(call if_changed_dep, dtc)
+
+is used to compile the DT source file (testcases.dts) into a binary blob
+(testcases.dtb), also referred as flattened DT.
+
+After that, using the following rule the binary blob above is wrapped as an
+assembly file (testcases.dtb.S)::
+
+ $(obj)/%.dtb.S: $(obj)/%.dtb
+ $(call cmd, dt_S_dtb)
+
+The assembly file is compiled into an object file (testcases.dtb.o), and is
+linked into the kernel image.
+
+
+2.1. Adding the test data
+-------------------------
+
+Un-flattened device tree structure:
+
+Un-flattened device tree consists of connected device_node(s) in form of a tree
+structure described below::
+
+ // following struct members are used to construct the tree
+ struct device_node {
+ ...
+ struct device_node *parent;
+ struct device_node *child;
+ struct device_node *sibling;
+ ...
+ };
+
+Figure 1, describes a generic structure of machine's un-flattened device tree
+considering only child and sibling pointers. There exists another pointer,
+``*parent``, that is used to traverse the tree in the reverse direction. So, at
+a particular level the child node and all the sibling nodes will have a parent
+pointer pointing to a common node (e.g. child1, sibling2, sibling3, sibling4's
+parent points to root node)::
+
+ root ('/')
+ |
+ child1 -> sibling2 -> sibling3 -> sibling4 -> null
+ | | | |
+ | | | null
+ | | |
+ | | child31 -> sibling32 -> null
+ | | | |
+ | | null null
+ | |
+ | child21 -> sibling22 -> sibling23 -> null
+ | | | |
+ | null null null
+ |
+ child11 -> sibling12 -> sibling13 -> sibling14 -> null
+ | | | |
+ | | | null
+ | | |
+ null null child131 -> null
+ |
+ null
+
+Figure 1: Generic structure of un-flattened device tree
+
+
+Before executing OF unittest, it is required to attach the test data to
+machine's device tree (if present). So, when selftest_data_add() is called,
+at first it reads the flattened device tree data linked into the kernel image
+via the following kernel symbols::
+
+ __dtb_testcases_begin - address marking the start of test data blob
+ __dtb_testcases_end - address marking the end of test data blob
+
+Secondly, it calls of_fdt_unflatten_tree() to unflatten the flattened
+blob. And finally, if the machine's device tree (i.e live tree) is present,
+then it attaches the unflattened test data tree to the live tree, else it
+attaches itself as a live device tree.
+
+attach_node_and_children() uses of_attach_node() to attach the nodes into the
+live tree as explained below. To explain the same, the test data tree described
+in Figure 2 is attached to the live tree described in Figure 1::
+
+ root ('/')
+ |
+ testcase-data
+ |
+ test-child0 -> test-sibling1 -> test-sibling2 -> test-sibling3 -> null
+ | | | |
+ test-child01 null null null
+
+
+Figure 2: Example test data tree to be attached to live tree.
+
+According to the scenario above, the live tree is already present so it isn't
+required to attach the root('/') node. All other nodes are attached by calling
+of_attach_node() on each node.
+
+In the function of_attach_node(), the new node is attached as the child of the
+given parent in live tree. But, if parent already has a child then the new node
+replaces the current child and turns it into its sibling. So, when the testcase
+data node is attached to the live tree above (Figure 1), the final structure is
+as shown in Figure 3::
+
+ root ('/')
+ |
+ testcase-data -> child1 -> sibling2 -> sibling3 -> sibling4 -> null
+ | | | | |
+ (...) | | | null
+ | | child31 -> sibling32 -> null
+ | | | |
+ | | null null
+ | |
+ | child21 -> sibling22 -> sibling23 -> null
+ | | | |
+ | null null null
+ |
+ child11 -> sibling12 -> sibling13 -> sibling14 -> null
+ | | | |
+ null null | null
+ |
+ child131 -> null
+ |
+ null
+ -----------------------------------------------------------------------
+
+ root ('/')
+ |
+ testcase-data -> child1 -> sibling2 -> sibling3 -> sibling4 -> null
+ | | | | |
+ | (...) (...) (...) null
+ |
+ test-sibling3 -> test-sibling2 -> test-sibling1 -> test-child0 -> null
+ | | | |
+ null null null test-child01
+
+
+Figure 3: Live device tree structure after attaching the testcase-data.
+
+
+Astute readers would have noticed that test-child0 node becomes the last
+sibling compared to the earlier structure (Figure 2). After attaching first
+test-child0 the test-sibling1 is attached that pushes the child node
+(i.e. test-child0) to become a sibling and makes itself a child node,
+as mentioned above.
+
+If a duplicate node is found (i.e. if a node with same full_name property is
+already present in the live tree), then the node isn't attached rather its
+properties are updated to the live tree's node by calling the function
+update_node_properties().
+
+
+2.2. Removing the test data
+---------------------------
+
+Once the test case execution is complete, selftest_data_remove is called in
+order to remove the device nodes attached initially (first the leaf nodes are
+detached and then moving up the parent nodes are removed, and eventually the
+whole tree). selftest_data_remove() calls detach_node_and_children() that uses
+of_detach_node() to detach the nodes from the live device tree.
+
+To detach a node, of_detach_node() either updates the child pointer of given
+node's parent to its sibling or attaches the previous sibling to the given
+node's sibling, as appropriate. That is it :)

-Figure 2: Example test data tree to be attached to live tree.
-
-According to the scenario above, the live tree is already present so it isn't
-required to attach the root('/') node. All other nodes are attached by calling
-of_attach_node() on each node.
-
-In the function of_attach_node(), the new node is attached as the child of the
-given parent in live tree. But, if parent already has a child then the new node
-replaces the current child and turns it into its sibling. So, when the testcase
-data node is attached to the live tree above (Figure 1), the final structure is
- as shown in Figure 3.
-
-root ('/')
- |
-testcase-data -> child1 -> sibling2 -> sibling3 -> sibling4 -> null
- | | | | |
- (...) | | | null
- | | child31 -> sibling32 -> null
- | | | |
- | | null null
- | |
- | child21 -> sibling22 -> sibling23 -> null
- | | | |
- | null null null
- |
- child11 -> sibling12 -> sibling13 -> sibling14 -> null
- | | | |
- null null | null
- |
- child131 -> null
- |
- null
------------------------------------------------------------------------
-
-root ('/')
- |
-testcase-data -> child1 -> sibling2 -> sibling3 -> sibling4 -> null
- | | | | |
- | (...) (...) (...) null
- |
-test-sibling3 -> test-sibling2 -> test-sibling1 -> test-child0 -> null
- | | | |
- null null null test-child01
-
-
-Figure 3: Live device tree structure after attaching the testcase-data.
-
-
-Astute readers would have noticed that test-child0 node becomes the last
-sibling compared to the earlier structure (Figure 2). After attaching first
-test-child0 the test-sibling1 is attached that pushes the child node
-(i.e. test-child0) to become a sibling and makes itself a child node,
- as mentioned above.
-
-If a duplicate node is found (i.e. if a node with same full_name property is
-already present in the live tree), then the node isn't attached rather its
-properties are updated to the live tree's node by calling the function
-update_node_properties().
-
-
-2.2. Removing the test data
-
-Once the test case execution is complete, selftest_data_remove is called in
-order to remove the device nodes attached initially (first the leaf nodes are
-detached and then moving up the parent nodes are removed, and eventually the
-whole tree). selftest_data_remove() calls detach_node_and_children() that uses
-of_detach_node() to detach the nodes from the live device tree.
-
-To detach a node, of_detach_node() either updates the child pointer of given
-node's parent to its sibling or attaches the previous sibling to the given
-node's sibling, as appropriate. That is it :)

+Device Tree Overlay Notes
+=========================
+
+This document describes the implementation of the in-kernel
+device tree overlay functionality residing in drivers/of/overlay.c and is a
+companion document to Documentation/devicetree/dynamic-resolution-notes.rst[1]
+
+How overlays work
+-----------------
+
+A Device Tree's overlay purpose is to modify the kernel's live tree, and
+have the modification affecting the state of the kernel in a way that
+is reflecting the changes.
+Since the kernel mainly deals with devices, any new device node that result
+in an active device should have it created while if the device node is either
+disabled or removed all together, the affected device should be deregistered.
+
+Lets take an example where we have a foo board with the following base tree::
+
+ ---- foo.dts ---------------------------------------------------------------
+ /* FOO platform */
+ /dts-v1/;
+ / {
+ compatible = "corp,foo";
+
+ /* shared resources */
+ res: res {
+ };
+
+ /* On chip peripherals */
+ ocp: ocp {
+ /* peripherals that are always instantiated */
+ peripheral1 { ... };
+ };
+ };
+ ---- foo.dts ---------------------------------------------------------------
+
+The overlay bar.dts,
+::
+
+ ---- bar.dts - overlay target location by label ----------------------------
+ /dts-v1/;
+ /plugin/;
+ &ocp {
+ /* bar peripheral */
+ bar {
+ compatible = "corp,bar";
+ ... /* various properties and child nodes */
+ };
+ };
+ ---- bar.dts ---------------------------------------------------------------
+
+when loaded (and resolved as described in [1]) should result in foo+bar.dts::
+
+ ---- foo+bar.dts -----------------------------------------------------------
+ /* FOO platform + bar peripheral */
+ / {
+ compatible = "corp,foo";
+
+ /* shared resources */
+ res: res {
+ };
+
+ /* On chip peripherals */
+ ocp: ocp {
+ /* peripherals that are always instantiated */
+ peripheral1 { ... };
+
+ /* bar peripheral */
+ bar {
+ compatible = "corp,bar";
+ ... /* various properties and child nodes */
+ };
+ };
+ };
+ ---- foo+bar.dts -----------------------------------------------------------
+
+As a result of the overlay, a new device node (bar) has been created
+so a bar platform device will be registered and if a matching device driver
+is loaded the device will be created as expected.
+
+If the base DT was not compiled with the -@ option then the "&ocp" label
+will not be available to resolve the overlay node(s) to the proper location
+in the base DT. In this case, the target path can be provided. The target
+location by label syntax is preferred because the overlay can be applied to
+any base DT containing the label, no matter where the label occurs in the DT.
+
+The above bar.dts example modified to use target path syntax is::
+
+ ---- bar.dts - overlay target location by explicit path --------------------
+ /dts-v1/;
+ /plugin/;
+ &{/ocp} {
+ /* bar peripheral */
+ bar {
+ compatible = "corp,bar";
+ ... /* various properties and child nodes */
+ }
+ };
+ ---- bar.dts ---------------------------------------------------------------
+
+
+Overlay in-kernel API
+--------------------------------
+
+The API is quite easy to use.
+
+1) Call of_overlay_fdt_apply() to create and apply an overlay changeset. The
+ return value is an error or a cookie identifying this overlay.
+
+2) Call of_overlay_remove() to remove and cleanup the overlay changeset
+ previously created via the call to of_overlay_fdt_apply(). Removal of an
+ overlay changeset that is stacked by another will not be permitted.
+
+Finally, if you need to remove all overlays in one-go, just call
+of_overlay_remove_all() which will remove every single one in the correct
+order.
+
+In addition, there is the option to register notifiers that get called on
+overlay operations. See of_overlay_notifier_register/unregister and
+enum of_overlay_notify_action for details.
+
+Note that a notifier callback is not supposed to store pointers to a device
+tree node or its content beyond OF_OVERLAY_POST_REMOVE corresponding to the
+respective node it received.

-contains the information required to map from a phandle to a tree location.

+=========================
+Linux and the Device Tree
+=========================
+
+The Linux usage model for device tree data
+
+:Author: Grant Likely <grant.likely@secretlab.ca>
+
+This article describes how Linux uses the device tree. An overview of
+the device tree data format can be found on the device tree usage page
+at devicetree.org\ [1]_.
+
+.. [1] https://elinux.org/Device_Tree_Usage
+
+The "Open Firmware Device Tree", or simply Device Tree (DT), is a data
+structure and language for describing hardware. More specifically, it
+is a description of hardware that is readable by an operating system
+so that the operating system doesn't need to hard code details of the
+machine.
+
+Structurally, the DT is a tree, or acyclic graph with named nodes, and
+nodes may have an arbitrary number of named properties encapsulating
+arbitrary data. A mechanism also exists to create arbitrary
+links from one node to another outside of the natural tree structure.
+
+Conceptually, a common set of usage conventions, called 'bindings',
+is defined for how data should appear in the tree to describe typical
+hardware characteristics including data busses, interrupt lines, GPIO
+connections, and peripheral devices.
+
+As much as possible, hardware is described using existing bindings to
+maximize use of existing support code, but since property and node
+names are simply text strings, it is easy to extend existing bindings
+or create new ones by defining new nodes and properties. Be wary,
+however, of creating a new binding without first doing some homework
+about what already exists. There are currently two different,
+incompatible, bindings for i2c busses that came about because the new
+binding was created without first investigating how i2c devices were
+already being enumerated in existing systems.
+
+1. History
+----------
+The DT was originally created by Open Firmware as part of the
+communication method for passing data from Open Firmware to a client
+program (like to an operating system). An operating system used the
+Device Tree to discover the topology of the hardware at runtime, and
+thereby support a majority of available hardware without hard coded
+information (assuming drivers were available for all devices).
+
+Since Open Firmware is commonly used on PowerPC and SPARC platforms,
+the Linux support for those architectures has for a long time used the
+Device Tree.
+
+In 2005, when PowerPC Linux began a major cleanup and to merge 32-bit
+and 64-bit support, the decision was made to require DT support on all
+powerpc platforms, regardless of whether or not they used Open
+Firmware. To do this, a DT representation called the Flattened Device
+Tree (FDT) was created which could be passed to the kernel as a binary
+blob without requiring a real Open Firmware implementation. U-Boot,
+kexec, and other bootloaders were modified to support both passing a
+Device Tree Binary (dtb) and to modify a dtb at boot time. DT was
+also added to the PowerPC boot wrapper (``arch/powerpc/boot/*``) so that
+a dtb could be wrapped up with the kernel image to support booting
+existing non-DT aware firmware.
+
+Some time later, FDT infrastructure was generalized to be usable by
+all architectures. At the time of this writing, 6 mainlined
+architectures (arm, microblaze, mips, powerpc, sparc, and x86) and 1
+out of mainline (nios) have some level of DT support.
+
+2. Data Model
+-------------
+If you haven't already read the Device Tree Usage\ [1]_ page,
+then go read it now. It's okay, I'll wait....
+
+2.1 High Level View
+-------------------
+The most important thing to understand is that the DT is simply a data
+structure that describes the hardware. There is nothing magical about
+it, and it doesn't magically make all hardware configuration problems
+go away. What it does do is provide a language for decoupling the
+hardware configuration from the board and device driver support in the
+Linux kernel (or any other operating system for that matter). Using
+it allows board and device support to become data driven; to make
+setup decisions based on data passed into the kernel instead of on
+per-machine hard coded selections.
+
+Ideally, data driven platform setup should result in less code
+duplication and make it easier to support a wide range of hardware
+with a single kernel image.
+
+Linux uses DT data for three major purposes:
+
+1) platform identification,
+2) runtime configuration, and
+3) device population.
+
+2.2 Platform Identification
+---------------------------
+First and foremost, the kernel will use data in the DT to identify the
+specific machine. In a perfect world, the specific platform shouldn't
+matter to the kernel because all platform details would be described
+perfectly by the device tree in a consistent and reliable manner.
+Hardware is not perfect though, and so the kernel must identify the
+machine during early boot so that it has the opportunity to run
+machine-specific fixups.
+
+In the majority of cases, the machine identity is irrelevant, and the
+kernel will instead select setup code based on the machine's core
+CPU or SoC. On ARM for example, setup_arch() in
+arch/arm/kernel/setup.c will call setup_machine_fdt() in
+arch/arm/kernel/devtree.c which searches through the machine_desc
+table and selects the machine_desc which best matches the device tree
+data. It determines the best match by looking at the 'compatible'
+property in the root device tree node, and comparing it with the
+dt_compat list in struct machine_desc (which is defined in
+arch/arm/include/asm/mach/arch.h if you're curious).
+
+The 'compatible' property contains a sorted list of strings starting
+with the exact name of the machine, followed by an optional list of
+boards it is compatible with sorted from most compatible to least. For
+example, the root compatible properties for the TI BeagleBoard and its
+successor, the BeagleBoard xM board might look like, respectively::
+
+ compatible = "ti,omap3-beagleboard", "ti,omap3450", "ti,omap3";
+ compatible = "ti,omap3-beagleboard-xm", "ti,omap3450", "ti,omap3";
+
+Where "ti,omap3-beagleboard-xm" specifies the exact model, it also
+claims that it compatible with the OMAP 3450 SoC, and the omap3 family
+of SoCs in general. You'll notice that the list is sorted from most
+specific (exact board) to least specific (SoC family).
+
+Astute readers might point out that the Beagle xM could also claim
+compatibility with the original Beagle board. However, one should be
+cautioned about doing so at the board level since there is typically a
+high level of change from one board to another, even within the same
+product line, and it is hard to nail down exactly what is meant when one
+board claims to be compatible with another. For the top level, it is
+better to err on the side of caution and not claim one board is
+compatible with another. The notable exception would be when one
+board is a carrier for another, such as a CPU module attached to a
+carrier board.
+
+One more note on compatible values. Any string used in a compatible
+property must be documented as to what it indicates. Add
+documentation for compatible strings in Documentation/devicetree/bindings.
+
+Again on ARM, for each machine_desc, the kernel looks to see if
+any of the dt_compat list entries appear in the compatible property.
+If one does, then that machine_desc is a candidate for driving the
+machine. After searching the entire table of machine_descs,
+setup_machine_fdt() returns the 'most compatible' machine_desc based
+on which entry in the compatible property each machine_desc matches
+against. If no matching machine_desc is found, then it returns NULL.
+
+The reasoning behind this scheme is the observation that in the majority
+of cases, a single machine_desc can support a large number of boards
+if they all use the same SoC, or same family of SoCs. However,
+invariably there will be some exceptions where a specific board will
+require special setup code that is not useful in the generic case.
+Special cases could be handled by explicitly checking for the
+troublesome board(s) in generic setup code, but doing so very quickly
+becomes ugly and/or unmaintainable if it is more than just a couple of
+cases.
+
+Instead, the compatible list allows a generic machine_desc to provide
+support for a wide common set of boards by specifying "less
+compatible" values in the dt_compat list. In the example above,
+generic board support can claim compatibility with "ti,omap3" or
+"ti,omap3450". If a bug was discovered on the original beagleboard
+that required special workaround code during early boot, then a new
+machine_desc could be added which implements the workarounds and only
+matches on "ti,omap3-beagleboard".
+
+PowerPC uses a slightly different scheme where it calls the .probe()
+hook from each machine_desc, and the first one returning TRUE is used.
+However, this approach does not take into account the priority of the
+compatible list, and probably should be avoided for new architecture
+support.
+
+2.3 Runtime configuration
+-------------------------
+In most cases, a DT will be the sole method of communicating data from
+firmware to the kernel, so also gets used to pass in runtime and
+configuration data like the kernel parameters string and the location
+of an initrd image.
+
+Most of this data is contained in the /chosen node, and when booting
+Linux it will look something like this::
+
+ chosen {
+ bootargs = "console=ttyS0,115200 loglevel=8";
+ initrd-start = <0xc8000000>;
+ initrd-end = <0xc8200000>;
+ };
+
+The bootargs property contains the kernel arguments, and the initrd-*
+properties define the address and size of an initrd blob. Note that
+initrd-end is the first address after the initrd image, so this doesn't
+match the usual semantic of struct resource. The chosen node may also
+optionally contain an arbitrary number of additional properties for
+platform-specific configuration data.
+
+During early boot, the architecture setup code calls of_scan_flat_dt()
+several times with different helper callbacks to parse device tree
+data before paging is setup. The of_scan_flat_dt() code scans through
+the device tree and uses the helpers to extract information required
+during early boot. Typically the early_init_dt_scan_chosen() helper
+is used to parse the chosen node including kernel parameters,
+early_init_dt_scan_root() to initialize the DT address space model,
+and early_init_dt_scan_memory() to determine the size and
+location of usable RAM.
+
+On ARM, the function setup_machine_fdt() is responsible for early
+scanning of the device tree after selecting the correct machine_desc
+that supports the board.
+
+2.4 Device population
+---------------------
+After the board has been identified, and after the early configuration data
+has been parsed, then kernel initialization can proceed in the normal
+way. At some point in this process, unflatten_device_tree() is called
+to convert the data into a more efficient runtime representation.
+This is also when machine-specific setup hooks will get called, like
+the machine_desc .init_early(), .init_irq() and .init_machine() hooks
+on ARM. The remainder of this section uses examples from the ARM
+implementation, but all architectures will do pretty much the same
+thing when using a DT.
+
+As can be guessed by the names, .init_early() is used for any machine-
+specific setup that needs to be executed early in the boot process,
+and .init_irq() is used to set up interrupt handling. Using a DT
+doesn't materially change the behaviour of either of these functions.
+If a DT is provided, then both .init_early() and .init_irq() are able
+to call any of the DT query functions (of_* in include/linux/of*.h) to
+get additional data about the platform.
+
+The most interesting hook in the DT context is .init_machine() which
+is primarily responsible for populating the Linux device model with
+data about the platform. Historically this has been implemented on
+embedded platforms by defining a set of static clock structures,
+platform_devices, and other data in the board support .c file, and
+registering it en-masse in .init_machine(). When DT is used, then
+instead of hard coding static devices for each platform, the list of
+devices can be obtained by parsing the DT, and allocating device
+structures dynamically.
+
+The simplest case is when .init_machine() is only responsible for
+registering a block of platform_devices. A platform_device is a concept
+used by Linux for memory or I/O mapped devices which cannot be detected
+by hardware, and for 'composite' or 'virtual' devices (more on those
+later). While there is no 'platform device' terminology for the DT,
+platform devices roughly correspond to device nodes at the root of the
+tree and children of simple memory mapped bus nodes.
+
+About now is a good time to lay out an example. Here is part of the
+device tree for the NVIDIA Tegra board::
+
+ /{
+ compatible = "nvidia,harmony", "nvidia,tegra20";
+ #address-cells = <1>;
+ #size-cells = <1>;
+ interrupt-parent = <&intc>;
+
+ chosen { };
+ aliases { };
+
+ memory {
+ device_type = "memory";
+ reg = <0x00000000 0x40000000>;
+ };
+
+ soc {
+ compatible = "nvidia,tegra20-soc", "simple-bus";
+ #address-cells = <1>;
+ #size-cells = <1>;
+ ranges;
+
+ intc: interrupt-controller@50041000 {
+ compatible = "nvidia,tegra20-gic";
+ interrupt-controller;
+ #interrupt-cells = <1>;
+ reg = <0x50041000 0x1000>, < 0x50040100 0x0100 >;
+ };
+
+ serial@70006300 {
+ compatible = "nvidia,tegra20-uart";
+ reg = <0x70006300 0x100>;
+ interrupts = <122>;
+ };
+
+ i2s1: i2s@70002800 {
+ compatible = "nvidia,tegra20-i2s";
+ reg = <0x70002800 0x100>;
+ interrupts = <77>;
+ codec = <&wm8903>;
+ };
+
+ i2c@7000c000 {
+ compatible = "nvidia,tegra20-i2c";
+ #address-cells = <1>;
+ #size-cells = <0>;
+ reg = <0x7000c000 0x100>;
+ interrupts = <70>;
+
+ wm8903: codec@1a {
+ compatible = "wlf,wm8903";
+ reg = <0x1a>;
+ interrupts = <347>;
+ };
+ };
+ };
+
+ sound {
+ compatible = "nvidia,harmony-sound";
+ i2s-controller = <&i2s1>;
+ i2s-codec = <&wm8903>;
+ };
+ };
+
+At .init_machine() time, Tegra board support code will need to look at
+this DT and decide which nodes to create platform_devices for.
+However, looking at the tree, it is not immediately obvious what kind
+of device each node represents, or even if a node represents a device
+at all. The /chosen, /aliases, and /memory nodes are informational
+nodes that don't describe devices (although arguably memory could be
+considered a device). The children of the /soc node are memory mapped
+devices, but the codec@1a is an i2c device, and the sound node
+represents not a device, but rather how other devices are connected
+together to create the audio subsystem. I know what each device is
+because I'm familiar with the board design, but how does the kernel
+know what to do with each node?
+
+The trick is that the kernel starts at the root of the tree and looks
+for nodes that have a 'compatible' property. First, it is generally
+assumed that any node with a 'compatible' property represents a device
+of some kind, and second, it can be assumed that any node at the root
+of the tree is either directly attached to the processor bus, or is a
+miscellaneous system device that cannot be described any other way.
+For each of these nodes, Linux allocates and registers a
+platform_device, which in turn may get bound to a platform_driver.
+
+Why is using a platform_device for these nodes a safe assumption?
+Well, for the way that Linux models devices, just about all bus_types
+assume that its devices are children of a bus controller. For
+example, each i2c_client is a child of an i2c_master. Each spi_device
+is a child of an SPI bus. Similarly for USB, PCI, MDIO, etc. The
+same hierarchy is also found in the DT, where I2C device nodes only
+ever appear as children of an I2C bus node. Ditto for SPI, MDIO, USB,
+etc. The only devices which do not require a specific type of parent
+device are platform_devices (and amba_devices, but more on that
+later), which will happily live at the base of the Linux /sys/devices
+tree. Therefore, if a DT node is at the root of the tree, then it
+really probably is best registered as a platform_device.
+
+Linux board support code calls of_platform_populate(NULL, NULL, NULL, NULL)
+to kick off discovery of devices at the root of the tree. The
+parameters are all NULL because when starting from the root of the
+tree, there is no need to provide a starting node (the first NULL), a
+parent struct device (the last NULL), and we're not using a match
+table (yet). For a board that only needs to register devices,
+.init_machine() can be completely empty except for the
+of_platform_populate() call.
+
+In the Tegra example, this accounts for the /soc and /sound nodes, but
+what about the children of the SoC node? Shouldn't they be registered
+as platform devices too? For Linux DT support, the generic behaviour
+is for child devices to be registered by the parent's device driver at
+driver .probe() time. So, an i2c bus device driver will register a
+i2c_client for each child node, an SPI bus driver will register
+its spi_device children, and similarly for other bus_types.
+According to that model, a driver could be written that binds to the
+SoC node and simply registers platform_devices for each of its
+children. The board support code would allocate and register an SoC
+device, a (theoretical) SoC device driver could bind to the SoC device,
+and register platform_devices for /soc/interrupt-controller, /soc/serial,
+/soc/i2s, and /soc/i2c in its .probe() hook. Easy, right?
+
+Actually, it turns out that registering children of some
+platform_devices as more platform_devices is a common pattern, and the
+device tree support code reflects that and makes the above example
+simpler. The second argument to of_platform_populate() is an
+of_device_id table, and any node that matches an entry in that table
+will also get its child nodes registered. In the Tegra case, the code

+
+ static void __init harmony_init_machine(void)

+
+"simple-bus" is defined in the Devicetree Specification as a property

+Appendix A: AMBA devices
+------------------------
+
+ARM Primecells are a certain kind of device attached to the ARM AMBA
+bus which include some support for hardware detection and power
+management. In Linux, struct amba_device and the amba_bus_type is
+used to represent Primecell devices. However, the fiddly bit is that
+not all devices on an AMBA bus are Primecells, and for Linux it is

+When using the DT, this creates problems for of_platform_populate()
+because it must decide whether to register each node as either a
+platform_device or an amba_device. This unfortunately complicates the

+be too invasive. If a node is compatible with "arm,amba-primecell", then
+of_platform_populate() will register it as an amba_device instead of a
+platform_device.

-Linux and the Device Tree
--------------------------
-The Linux usage model for device tree data
-
-Author: Grant Likely <grant.likely@secretlab.ca>
-
-This article describes how Linux uses the device tree. An overview of
-the device tree data format can be found on the device tree usage page
-at devicetree.org[1].
-
-[1] http://devicetree.org/Device_Tree_Usage
-
-The "Open Firmware Device Tree", or simply Device Tree (DT), is a data
-structure and language for describing hardware. More specifically, it
-is a description of hardware that is readable by an operating system
-so that the operating system doesn't need to hard code details of the
-machine.
-
-Structurally, the DT is a tree, or acyclic graph with named nodes, and
-nodes may have an arbitrary number of named properties encapsulating
-arbitrary data. A mechanism also exists to create arbitrary
-links from one node to another outside of the natural tree structure.
-
-Conceptually, a common set of usage conventions, called 'bindings',
-is defined for how data should appear in the tree to describe typical
-hardware characteristics including data busses, interrupt lines, GPIO
-connections, and peripheral devices.
-
-As much as possible, hardware is described using existing bindings to
-maximize use of existing support code, but since property and node
-names are simply text strings, it is easy to extend existing bindings
-or create new ones by defining new nodes and properties. Be wary,
-however, of creating a new binding without first doing some homework
-about what already exists. There are currently two different,
-incompatible, bindings for i2c busses that came about because the new
-binding was created without first investigating how i2c devices were
-already being enumerated in existing systems.
-
-1. History
-----------
-The DT was originally created by Open Firmware as part of the
-communication method for passing data from Open Firmware to a client
-program (like to an operating system). An operating system used the
-Device Tree to discover the topology of the hardware at runtime, and
-thereby support a majority of available hardware without hard coded
-information (assuming drivers were available for all devices).
-
-Since Open Firmware is commonly used on PowerPC and SPARC platforms,
-the Linux support for those architectures has for a long time used the
-Device Tree.
-
-In 2005, when PowerPC Linux began a major cleanup and to merge 32-bit
-and 64-bit support, the decision was made to require DT support on all
-powerpc platforms, regardless of whether or not they used Open
-Firmware. To do this, a DT representation called the Flattened Device
-Tree (FDT) was created which could be passed to the kernel as a binary
-blob without requiring a real Open Firmware implementation. U-Boot,
-kexec, and other bootloaders were modified to support both passing a
-Device Tree Binary (dtb) and to modify a dtb at boot time. DT was
-also added to the PowerPC boot wrapper (arch/powerpc/boot/*) so that
-a dtb could be wrapped up with the kernel image to support booting
-existing non-DT aware firmware.
-
-Some time later, FDT infrastructure was generalized to be usable by
-all architectures. At the time of this writing, 6 mainlined
-architectures (arm, microblaze, mips, powerpc, sparc, and x86) and 1
-out of mainline (nios) have some level of DT support.
-
-2. Data Model
--------------
-If you haven't already read the Device Tree Usage[1] page,
-then go read it now. It's okay, I'll wait....
-
-2.1 High Level View
--------------------
-The most important thing to understand is that the DT is simply a data
-structure that describes the hardware. There is nothing magical about
-it, and it doesn't magically make all hardware configuration problems
-go away. What it does do is provide a language for decoupling the
-hardware configuration from the board and device driver support in the
-Linux kernel (or any other operating system for that matter). Using
-it allows board and device support to become data driven; to make
-setup decisions based on data passed into the kernel instead of on
-per-machine hard coded selections.
-
-Ideally, data driven platform setup should result in less code
-duplication and make it easier to support a wide range of hardware
-with a single kernel image.
-
-Linux uses DT data for three major purposes:
-1) platform identification,
-2) runtime configuration, and
-3) device population.
-
-2.2 Platform Identification
----------------------------
-First and foremost, the kernel will use data in the DT to identify the
-specific machine. In a perfect world, the specific platform shouldn't
-matter to the kernel because all platform details would be described
-perfectly by the device tree in a consistent and reliable manner.
-Hardware is not perfect though, and so the kernel must identify the
-machine during early boot so that it has the opportunity to run
-machine-specific fixups.
-
-In the majority of cases, the machine identity is irrelevant, and the
-kernel will instead select setup code based on the machine's core
-CPU or SoC. On ARM for example, setup_arch() in
-arch/arm/kernel/setup.c will call setup_machine_fdt() in
-arch/arm/kernel/devtree.c which searches through the machine_desc
-table and selects the machine_desc which best matches the device tree
-data. It determines the best match by looking at the 'compatible'
-property in the root device tree node, and comparing it with the
-dt_compat list in struct machine_desc (which is defined in
-arch/arm/include/asm/mach/arch.h if you're curious).
-
-The 'compatible' property contains a sorted list of strings starting
-with the exact name of the machine, followed by an optional list of
-boards it is compatible with sorted from most compatible to least. For
-example, the root compatible properties for the TI BeagleBoard and its
-successor, the BeagleBoard xM board might look like, respectively:
-
- compatible = "ti,omap3-beagleboard", "ti,omap3450", "ti,omap3";
- compatible = "ti,omap3-beagleboard-xm", "ti,omap3450", "ti,omap3";
-
-Where "ti,omap3-beagleboard-xm" specifies the exact model, it also
-claims that it compatible with the OMAP 3450 SoC, and the omap3 family
-of SoCs in general. You'll notice that the list is sorted from most
-specific (exact board) to least specific (SoC family).
-
-Astute readers might point out that the Beagle xM could also claim
-compatibility with the original Beagle board. However, one should be
-cautioned about doing so at the board level since there is typically a
-high level of change from one board to another, even within the same
-product line, and it is hard to nail down exactly what is meant when one
-board claims to be compatible with another. For the top level, it is
-better to err on the side of caution and not claim one board is
-compatible with another. The notable exception would be when one
-board is a carrier for another, such as a CPU module attached to a
-carrier board.
-
-One more note on compatible values. Any string used in a compatible
-property must be documented as to what it indicates. Add
-documentation for compatible strings in Documentation/devicetree/bindings.
-
-Again on ARM, for each machine_desc, the kernel looks to see if
-any of the dt_compat list entries appear in the compatible property.
-If one does, then that machine_desc is a candidate for driving the
-machine. After searching the entire table of machine_descs,
-setup_machine_fdt() returns the 'most compatible' machine_desc based
-on which entry in the compatible property each machine_desc matches
-against. If no matching machine_desc is found, then it returns NULL.
-
-The reasoning behind this scheme is the observation that in the majority
-of cases, a single machine_desc can support a large number of boards
-if they all use the same SoC, or same family of SoCs. However,
-invariably there will be some exceptions where a specific board will
-require special setup code that is not useful in the generic case.
-Special cases could be handled by explicitly checking for the
-troublesome board(s) in generic setup code, but doing so very quickly
-becomes ugly and/or unmaintainable if it is more than just a couple of
-cases.
-
-Instead, the compatible list allows a generic machine_desc to provide
-support for a wide common set of boards by specifying "less
-compatible" values in the dt_compat list. In the example above,
-generic board support can claim compatibility with "ti,omap3" or
-"ti,omap3450". If a bug was discovered on the original beagleboard
-that required special workaround code during early boot, then a new
-machine_desc could be added which implements the workarounds and only
-matches on "ti,omap3-beagleboard".
-
-PowerPC uses a slightly different scheme where it calls the .probe()
-hook from each machine_desc, and the first one returning TRUE is used.
-However, this approach does not take into account the priority of the
-compatible list, and probably should be avoided for new architecture
-support.
-
-2.3 Runtime configuration
--------------------------
-In most cases, a DT will be the sole method of communicating data from
-firmware to the kernel, so also gets used to pass in runtime and
-configuration data like the kernel parameters string and the location
-of an initrd image.
-
-Most of this data is contained in the /chosen node, and when booting
-Linux it will look something like this:
-
- chosen {
- bootargs = "console=ttyS0,115200 loglevel=8";
- initrd-start = <0xc8000000>;
- initrd-end = <0xc8200000>;
- };
-
-The bootargs property contains the kernel arguments, and the initrd-*
-properties define the address and size of an initrd blob. Note that
-initrd-end is the first address after the initrd image, so this doesn't
-match the usual semantic of struct resource. The chosen node may also
-optionally contain an arbitrary number of additional properties for
-platform-specific configuration data.
-
-During early boot, the architecture setup code calls of_scan_flat_dt()
-several times with different helper callbacks to parse device tree
-data before paging is setup. The of_scan_flat_dt() code scans through
-the device tree and uses the helpers to extract information required
-during early boot. Typically the early_init_dt_scan_chosen() helper
-is used to parse the chosen node including kernel parameters,
-early_init_dt_scan_root() to initialize the DT address space model,
-and early_init_dt_scan_memory() to determine the size and
-location of usable RAM.
-
-On ARM, the function setup_machine_fdt() is responsible for early
-scanning of the device tree after selecting the correct machine_desc
-that supports the board.
-
-2.4 Device population
----------------------
-After the board has been identified, and after the early configuration data
-has been parsed, then kernel initialization can proceed in the normal
-way. At some point in this process, unflatten_device_tree() is called
-to convert the data into a more efficient runtime representation.
-This is also when machine-specific setup hooks will get called, like
-the machine_desc .init_early(), .init_irq() and .init_machine() hooks
-on ARM. The remainder of this section uses examples from the ARM
-implementation, but all architectures will do pretty much the same
-thing when using a DT.
-
-As can be guessed by the names, .init_early() is used for any machine-
-specific setup that needs to be executed early in the boot process,
-and .init_irq() is used to set up interrupt handling. Using a DT
-doesn't materially change the behaviour of either of these functions.
-If a DT is provided, then both .init_early() and .init_irq() are able
-to call any of the DT query functions (of_* in include/linux/of*.h) to
-get additional data about the platform.
-
-The most interesting hook in the DT context is .init_machine() which
-is primarily responsible for populating the Linux device model with
-data about the platform. Historically this has been implemented on
-embedded platforms by defining a set of static clock structures,
-platform_devices, and other data in the board support .c file, and
-registering it en-masse in .init_machine(). When DT is used, then
-instead of hard coding static devices for each platform, the list of
-devices can be obtained by parsing the DT, and allocating device
-structures dynamically.
-
-The simplest case is when .init_machine() is only responsible for
-registering a block of platform_devices. A platform_device is a concept
-used by Linux for memory or I/O mapped devices which cannot be detected
-by hardware, and for 'composite' or 'virtual' devices (more on those
-later). While there is no 'platform device' terminology for the DT,
-platform devices roughly correspond to device nodes at the root of the
-tree and children of simple memory mapped bus nodes.
-
-About now is a good time to lay out an example. Here is part of the
-device tree for the NVIDIA Tegra board.
-
-/{
- compatible = "nvidia,harmony", "nvidia,tegra20";
- #address-cells = <1>;
- #size-cells = <1>;

- #address-cells = <1>;
- #size-cells = <1>;

-
- intc: interrupt-controller@50041000 {
- compatible = "nvidia,tegra20-gic";
- interrupt-controller;
- #interrupt-cells = <1>;
- reg = <0x50041000 0x1000>, < 0x50040100 0x0100 >;
- };
-
- serial@70006300 {
- compatible = "nvidia,tegra20-uart";
- reg = <0x70006300 0x100>;
- interrupts = <122>;
- };
-
- i2s1: i2s@70002800 {
- compatible = "nvidia,tegra20-i2s";
- reg = <0x70002800 0x100>;
- interrupts = <77>;
- codec = <&wm8903>;
- };
-
- i2c@7000c000 {
- compatible = "nvidia,tegra20-i2c";
- #address-cells = <1>;
- #size-cells = <0>;
- reg = <0x7000c000 0x100>;
- interrupts = <70>;
-
- wm8903: codec@1a {
- compatible = "wlf,wm8903";
- reg = <0x1a>;
- interrupts = <347>;
- };
- };
- };
-
- sound {
- compatible = "nvidia,harmony-sound";
- i2s-controller = <&i2s1>;
- i2s-codec = <&wm8903>;
- };
-};
-
-At .init_machine() time, Tegra board support code will need to look at
-this DT and decide which nodes to create platform_devices for.
-However, looking at the tree, it is not immediately obvious what kind
-of device each node represents, or even if a node represents a device
-at all. The /chosen, /aliases, and /memory nodes are informational
-nodes that don't describe devices (although arguably memory could be
-considered a device). The children of the /soc node are memory mapped
-devices, but the codec@1a is an i2c device, and the sound node
-represents not a device, but rather how other devices are connected
-together to create the audio subsystem. I know what each device is
-because I'm familiar with the board design, but how does the kernel
-know what to do with each node?
-
-The trick is that the kernel starts at the root of the tree and looks
-for nodes that have a 'compatible' property. First, it is generally
-assumed that any node with a 'compatible' property represents a device
-of some kind, and second, it can be assumed that any node at the root
-of the tree is either directly attached to the processor bus, or is a
-miscellaneous system device that cannot be described any other way.
-For each of these nodes, Linux allocates and registers a
-platform_device, which in turn may get bound to a platform_driver.
-
-Why is using a platform_device for these nodes a safe assumption?
-Well, for the way that Linux models devices, just about all bus_types
-assume that its devices are children of a bus controller. For
-example, each i2c_client is a child of an i2c_master. Each spi_device
-is a child of an SPI bus. Similarly for USB, PCI, MDIO, etc. The
-same hierarchy is also found in the DT, where I2C device nodes only
-ever appear as children of an I2C bus node. Ditto for SPI, MDIO, USB,
-etc. The only devices which do not require a specific type of parent
-device are platform_devices (and amba_devices, but more on that
-later), which will happily live at the base of the Linux /sys/devices
-tree. Therefore, if a DT node is at the root of the tree, then it
-really probably is best registered as a platform_device.
-
-Linux board support code calls of_platform_populate(NULL, NULL, NULL, NULL)
-to kick off discovery of devices at the root of the tree. The
-parameters are all NULL because when starting from the root of the
-tree, there is no need to provide a starting node (the first NULL), a
-parent struct device (the last NULL), and we're not using a match
-table (yet). For a board that only needs to register devices,
-.init_machine() can be completely empty except for the
-of_platform_populate() call.
-
-In the Tegra example, this accounts for the /soc and /sound nodes, but
-what about the children of the SoC node? Shouldn't they be registered
-as platform devices too? For Linux DT support, the generic behaviour
-is for child devices to be registered by the parent's device driver at
-driver .probe() time. So, an i2c bus device driver will register a
-i2c_client for each child node, an SPI bus driver will register
-its spi_device children, and similarly for other bus_types.
