 *
 * @name: Optional name of the regmap. Useful when a device has multiple

 *
 * @reg_bits: Number of bits in a register address, mandatory.
 * @reg_stride: The register address stride. Valid register addresses are a

 *              used.
 * @pad_bits: Number of bits of padding between register and value.
 * @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).

 *                can be read from. If this field is NULL but rd_table
 *                 (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).
 * @writeable_noinc_reg: Optional callback returning true if the register
 *                      supports multiple write operations without incrementing
 *                      the register number. If this field is NULL but

 *                      by wr_noinc_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

 * @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.
 * @wr_noinc_table: As above, for no increment writeable 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_read: If set, converts the bulk read operation into a series of
 *                   single read operations. This is useful for a device that
 *                   does not support  bulk read.
 * @use_single_write: If set, converts the bulk write operation into a series of
 *                    single write operations. This is useful for a device that
 *                    does not support bulk 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
 *                     DEFAULT, the @reg_format_endian_default value from the
 *                     regmap bus is used.
 * @val_format_endian: Endianness for formatted register values. If this is
 *                     DEFAULT, the @reg_format_endian_default value from the
 *                     regmap bus is used.
 *
 * @ranges: Array of configuration entries for virtual address ranges.
 * @num_ranges: Number of range configuration entries.
 * @use_hwlock: Indicate if a hardware spinlock should be used.
 * @hwlock_id: Specify the hardware spinlock id.
 * @hwlock_mode: The hardware spinlock mode, should be HWLOCK_IRQSTATE,
 *               HWLOCK_IRQ or 0.

/**
 * struct regmap_bus - Description of a hardware bus for the register map
 *                     infrastructure.
 *
 * @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).
 * @write: Write operation.
 * @gather_write: Write operation with split register/value, return -ENOTSUPP
 *                if not implemented  on a given device.
 * @async_write: Write operation which completes asynchronously, optional and
 *               must serialise with respect to non-async I/O.
 * @reg_write: Write a single register value to the given register address. This
 *             write operation has to complete when returning from the function.
 * @reg_update_bits: Update bits operation to be used against volatile
 *                   registers, intended for devices supporting some mechanism
 *                   for setting clearing bits without having to
 *                   read/modify/write.
 * @read: Read operation.  Data is returned in the buffer used to transmit
 *         data.
 * @reg_read: Read a single register value from a given register address.
 * @free_context: Free context.
 * @async_alloc: Allocate a regmap_async() structure.
 * @read_flag_mask: Mask to be set in the top byte of the register when doing
 *                  a read.
 * @reg_format_endian_default: Default endianness for formatted register
 *     addresses. Used when the regmap_config specifies DEFAULT. If this is
 *     DEFAULT, BIG is assumed.
 * @val_format_endian_default: Default endianness for formatted register
 *     values. Used when the regmap_config specifies DEFAULT. If this is
 *     DEFAULT, BIG is assumed.
 * @max_raw_read: Max raw read size that can be used on the bus.
 * @max_raw_write: Max raw write size that can be used on the bus.
