* @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 whos 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 index.
* @wr_table: Optional, points to a struct regmap_access_table specifying
* valid ranges for write access.
