+ *
+ * MPU401 and SPDIF are not supported yet. I don't have the hardware
+ * to aid in coding and testing, so I won't bother.
+ *
+ * To quickly load the module,
+ *
+ * modprobe -a snd-cmi8330 sbport=0x220 sbirq=5 sbdma8=1
+ * sbdma16=5 wssport=0x530 wssirq=11 wssdma=0 fmport=0x388
+ *
+ * This card has two mixers and two PCM devices. I've cheesed it such
+ * that recording and playback can be done through the same device.
+ * The driver "magically" routes the capturing to the AD1848 codec,
+ * and playback to the SB16 codec. This allows for full-duplex mode
+ * to some extent.
+ * The utilities in alsa-utils are aware of both devices, so passing
+ * the appropriate parameters to amixer and alsactl will give you
+ * full control over both mixers.

+ * often need to trigger down and then up very quickly).
+ * Any ideas?
+ * - Support for 16 bit DMA seems to be broken. I've no hardware to tune it.
+ */
+
+/*
+ * ES1868 NOTES:
+ * - The chip has one half duplex pcm (with very limited full duplex support).
+ *
+ * - Duplex stereophonic sound is impossible.
+ * - Record and playback must share the same frequency rate.
+ *
+ * - The driver use dma2 for playback and dma1 for capture.
+ */
+
+/*
+ * ES1869 NOTES:
+ *
+ * - there are a first full duplex pcm and a second playback only pcm
+ * (incompatible with first pcm capture)
+ *
+ * - there is support for the capture volume and ESS Spatializer 3D effect.
+ *
+ * - contrarily to some pages in DS_1869.PDF the rates can be set
+ * independently.
+ *
+ * - Zoom Video is implemented by sharing the FM DAC, thus the user can
+ * have either FM playback or Video playback but not both simultaneously.
+ * The Video Playback Switch mixer control toggles this choice.
+ *
+ * BUGS:
+ *
+ * - There is a major trouble I noted:
+ *
+ * using both channel for playback stereo 16 bit samples at 44100 Hz
+ * the second pcm (Audio1) DMA slows down irregularly and sound is garbled.
+ *
+ * The same happens using Audio1 for captureing.
+ *
+ * The Windows driver does not suffer of this (although it use Audio1
+ * only for captureing). I'm unable to discover why.
+ *
+ */
+
+/*
+ * ES1879 NOTES:
+ * - When Zoom Video is enabled (reg 0x71 bit 6 toggled on) the PCM playback
+ * seems to be effected (speaker_test plays a lower frequency). Can't find
+ * anything in the datasheet to account for this, so a Video Playback Switch
+ * control has been included to allow ZV to be enabled only when necessary.
+ * Then again on at least one test system the 0x71 bit 6 enable bit is not
+ * needed for ZV, so maybe the datasheet is entirely wrong here.

+ * since there is no classic driver for alsa yet (i dont have a classic

+ * "uncomment this to make this a module again"
+ * to do guess what.

+ * to make it easier for some brave heart to implemt classic

+ * Routines for control of 16-bit SoundBlaster cards and clones
+ * Note: This is very ugly hardware which uses one 8-bit DMA channel and
+ * second 16-bit DMA channel. Unfortunately 8-bit DMA channel can't
+ * transfer 16-bit samples and 16-bit DMA channels can't transfer
+ * 8-bit samples. This make full duplex more complicated than
+ * can be... People, don't buy these soundcards for full 16-bit
+ * duplex!!!
+ * Note: 16-bit wide is assigned to first direction which made request.
+ * With full duplex - playback is preferred with abstract layer.
+ *
+ * Note: Some chip revisions have hardware bug. Changing capture
+ * channel from full-duplex 8bit DMA to 16bit DMA will block
+ * 16bit DMA transfers from DSP chip (capture) until 8bit transfer
+ * to DSP chip (playback) starts. This bug can be avoided with
+ * "16bit DMA Allocation" setting set to Playback or Capture.

+/* The low level driver for the WaveFront ICS2115 MIDI interface(s)
+ *
+ * Note that there is also an MPU-401 emulation (actually, a UART-401
+ * emulation) on the CS4232 on the Tropez and Tropez Plus. This code
+ * has nothing to do with that interface at all.
+ *
+ * The interface is essentially just a UART-401, but is has the
+ * interesting property of supporting what Turtle Beach called
+ * "Virtual MIDI" mode. In this mode, there are effectively *two*
+ * MIDI buses accessible via the interface, one that is routed
+ * solely to/from the external WaveFront synthesizer and the other
+ * corresponding to the pin/socket connector used to link external
+ * MIDI devices to the board.
+ *
+ * This driver fully supports this mode, allowing two distinct MIDI
+ * busses to be used completely independently, giving 32 channels of
+ * MIDI routing, 16 to the WaveFront synth and 16 to the external MIDI
+ * bus. The devices are named /dev/snd/midiCnD0 and /dev/snd/midiCnD1,
+ * where `n' is the card number. Note that the device numbers may be
+ * something other than 0 and 1 if the CS4232 UART/MPU-401 interface
+ * is enabled.
+ *
+ * Switching between the two is accomplished externally by the driver
+ * using the two otherwise unused MIDI bytes. See the code for more details.
+ *
+ * NOTE: VIRTUAL MIDI MODE IS ON BY DEFAULT (see lowlevel/isa/wavefront.c)
+ *
+ * The main reason to turn off Virtual MIDI mode is when you want to
+ * tightly couple the WaveFront synth with an external MIDI
+ * device. You won't be able to distinguish the source of any MIDI
+ * data except via SysEx ID, but thats probably OK, since for the most
+ * part, the WaveFront won't be sending any MIDI data at all.
+ *
+ * The main reason to turn on Virtual MIDI Mode is to provide two
+ * completely independent 16-channel MIDI buses, one to the
+ * WaveFront and one to any external MIDI devices. Given the 32
+ * voice nature of the WaveFront, its pretty easy to find a use
+ * for all 16 channels driving just that synth.
