278 * is guaranteed not to be accessed from multiple threads.

283 * @lock_arg: this field is passed as the only argument of lock/unlock
284 * functions (ignored in case regular lock/unlock functions

287 * all the reads from the registers. Should only be provided for
288 * devices whose read operation cannot be represented as a simple
289 * read operation on a bus such as SPI, I2C, etc. Most of the
290 * devices do not need this.
291 * @reg_write: Same as above for writing.
292 * @reg_update_bits: Optional callback that if filled will be used to perform
293 * all the update_bits(rmw) operation. Should only be provided
294 * if the function require special handling with lock and reg
295 * handling and the operation cannot be represented as a simple
296 * update_bits operation on a bus such as SPI, I2C, etc.
297 * @read: Optional callback that if filled will be used to perform all the
298 * bulk reads from the registers. Data is returned in the buffer used
300 * @write: Same as above for writing.
301 * @max_raw_read: Max raw read size that can be used on the device.
302 * @max_raw_write: Max raw write size that can be used on the device.
303 * @fast_io: Register IO is fast. Use a spinlock instead of a mutex
304 * to perform locking. This field is ignored if custom lock/unlock
305 * functions are used (see fields lock/unlock of struct regmap_config).
306 * This field is a duplicate of a similar file in
307 * 'struct regmap_bus' and serves exact same purpose.
308 * Use it only for "no-bus" cases.

316 * @rd_noinc_table: As above, for no increment readable registers.
317 * @reg_defaults: Power on reset values for registers (for use with
318 * register cache support).

321 * @read_flag_mask: Mask to be set in the top bytes of the register when doing
323 * @write_flag_mask: Mask to be set in the top bytes of the register when doing
324 * a write. If both read_flag_mask and write_flag_mask are
325 * empty and zero_flag_mask is not set the regmap_bus default
327 * @zero_flag_mask: If set, read_flag_mask and write_flag_mask are used even
328 * if they are both empty.
329 * @use_single_read: If set, converts the bulk read operation into a series of
330 * single read operations. This is useful for a device that
331 * does not support bulk read.
332 * @use_single_write: If set, converts the bulk write operation into a series of
333 * single write operations. This is useful for a device that
334 * does not support bulk write.
335 * @can_multi_write: If set, the device supports the multi write mode of bulk
336 * write operations, if clear multi write requests will be
337 * split into individual write operations
339 * @cache_type: The actual cache type.
340 * @reg_defaults_raw: Power on reset values for registers (for use with
341 * register cache support).
342 * @num_reg_defaults_raw: Number of elements in reg_defaults_raw.
343 * @reg_format_endian: Endianness for formatted register addresses. If this is
