+ * @val_bits: Number of bits in a register value, mandatory.
+ *
+ * @writeable_reg: Optional callback returning true if the register
+ * can be written to. If this field is NULL but wr_table
+ * (see below) is not, the check is performed on such table
+ * (a register is writeable if it belongs to one of the ranges
+ * specified by wr_table).
+ * @readable_reg: Optional callback returning true if the register

+ * (see below) is not, the check is performed on such table
+ * (a register is readable if it belongs to one of the ranges
+ * specified by rd_table).
+ * @volatile_reg: Optional callback returning true if the register
+ * value can't be cached. If this field is NULL but
+ * volatile_table (see below) is not, the check is performed on
+ * such table (a register is volatile if it belongs to one of
+ * the ranges specified by volatile_table).
+ * @precious_reg: Optional callback returning true if the register
+ * should not be read outside of a call from the driver
+ * (e.g., a clear on read interrupt status register). If this
+ * field is NULL but precious_table (see below) is not, the
+ * check is performed on such table (a register is precious if
+ * it belongs to one of the ranges specified by precious_table).
+ * @readable_noinc_reg: Optional callback returning true if the register
+ * supports multiple read operations without incrementing
+ * the register number. If this field is NULL but
+ * rd_noinc_table (see below) is not, the check is
+ * performed on such table (a register is no increment
+ * readable if it belongs to one of the ranges specified
+ * by rd_noinc_table).
+ * @disable_locking: This regmap is either protected by external means or
+ * is guaranteed not be be accessed from multiple threads.
+ * Don't use any locking mechanisms.
+ * @lock: Optional lock callback (overrides regmap's default lock
+ * function, based on spinlock or mutex).
+ * @unlock: As above for unlocking.
+ * @lock_arg: this field is passed as the only argument of lock/unlock
+ * functions (ignored in case regular lock/unlock functions
+ * are not overridden).
+ * @reg_read: Optional callback that if filled will be used to perform
+ * all the reads from the registers. Should only be provided for
+ * devices whose read operation cannot be represented as a simple
+ * read operation on a bus such as SPI, I2C, etc. Most of the
+ * devices do not need this.
+ * @reg_write: Same as above for writing.
+ * @fast_io: Register IO is fast. Use a spinlock instead of a mutex
+ * to perform locking. This field is ignored if custom lock/unlock
+ * functions are used (see fields lock/unlock of struct regmap_config).
+ * This field is a duplicate of a similar file in
+ * 'struct regmap_bus' and serves exact same purpose.
+ * Use it only for "no-bus" cases.
+ * @max_register: Optional, specifies the maximum valid register address.
+ * @wr_table: Optional, points to a struct regmap_access_table specifying
+ * valid ranges for write access.
+ * @rd_table: As above, for read access.
+ * @volatile_table: As above, for volatile registers.
+ * @precious_table: As above, for precious registers.
+ * @rd_noinc_table: As above, for no increment readable registers.
+ * @reg_defaults: Power on reset values for registers (for use with
+ * register cache support).
+ * @num_reg_defaults: Number of elements in reg_defaults.
+ *
+ * @read_flag_mask: Mask to be set in the top bytes of the register when doing
+ * a read.
+ * @write_flag_mask: Mask to be set in the top bytes of the register when doing
+ * a write. If both read_flag_mask and write_flag_mask are
+ * empty and zero_flag_mask is not set the regmap_bus default
+ * masks are used.
+ * @zero_flag_mask: If set, read_flag_mask and write_flag_mask are used even
+ * if they are both empty.
+ * @use_single_rw: If set, converts the bulk read and write operations into
+ * a series of single read and write operations. This is useful
+ * for device that does not support bulk read and write.
+ * @can_multi_write: If set, the device supports the multi write mode of bulk
+ * write operations, if clear multi write requests will be
+ * split into individual write operations
+ *
+ * @cache_type: The actual cache type.
+ * @reg_defaults_raw: Power on reset values for registers (for use with
+ * register cache support).
+ * @num_reg_defaults_raw: Number of elements in reg_defaults_raw.
+ * @reg_format_endian: Endianness for formatted register addresses. If this is

+ * @val_format_endian: Endianness for formatted register values. If this is

+ *
+ * @ranges: Array of configuration entries for virtual address ranges.
