236  *
237  * @reg_bits: Number of bits in a register address, mandatory.
238  * @reg_stride: The register address stride. Valid register addresses are a

242  * @val_bits: Number of bits in a register value, mandatory.
243  *
244  * @writeable_reg: Optional callback returning true if the register
245  *		   can be written to. If this field is NULL but wr_table
246  *		   (see below) is not, the check is performed on such table
247  *                 (a register is writeable if it belongs to one of the ranges
248  *                  specified by wr_table).

258  *                the ranges specified by volatile_table).
259  * @precious_reg: Optional callback returning true if the register
260  *		  should not be read outside of a call from the driver
261  *		  (e.g., a clear on read interrupt status register). If this
262  *                field is NULL but precious_table (see below) is not, the
263  *                check is performed on such table (a register is precious if
264  *                it belongs to one of the ranges specified by precious_table).
265  * @writeable_noinc_reg: Optional callback returning true if the register
266  *			supports multiple write operations without incrementing
267  *			the register number. If this field is NULL but
268  *			wr_noinc_table (see below) is not, the check is
269  *			performed on such table (a register is no increment
270  *			writeable if it belongs to one of the ranges specified
271  *			by wr_noinc_table).
272  * @readable_noinc_reg: Optional callback returning true if the register
273  *			supports multiple read operations without incrementing
274  *			the register number. If this field is NULL but
275  *			rd_noinc_table (see below) is not, the check is

280  *                   is guaranteed not to be accessed from multiple threads.
281  *                   Don't use any locking mechanisms.
282  * @lock:	  Optional lock callback (overrides regmap's default lock
283  *		  function, based on spinlock or mutex).
284  * @unlock:	  As above for unlocking.
285  * @lock_arg:	  this field is passed as the only argument of lock/unlock
286  *		  functions (ignored in case regular lock/unlock functions
287  *		  are not overridden).
288  * @reg_read:	  Optional callback that if filled will be used to perform
289  *           	  all the reads from the registers. Should only be provided for
290  *		  devices whose read operation cannot be represented as a simple
291  *		  read operation on a bus such as SPI, I2C, etc. Most of the
292  *		  devices do not need this.
293  * @reg_write:	  Same as above for writing.
294  * @reg_update_bits: Optional callback that if filled will be used to perform
295  *		     all the update_bits(rmw) operation. Should only be provided
296  *		     if the function require special handling with lock and reg
297  *		     handling and the operation cannot be represented as a simple
298  *		     update_bits operation on a bus such as SPI, I2C, etc.
299  * @fast_io:	  Register IO is fast. Use a spinlock instead of a mutex
300  *	     	  to perform locking. This field is ignored if custom lock/unlock
301  *	     	  functions are used (see fields lock/unlock of struct regmap_config).
302  *		  This field is a duplicate of a similar file in
303  *		  'struct regmap_bus' and serves exact same purpose.
304  *		   Use it only for "no-bus" cases.
305  * @max_register: Optional, specifies the maximum valid register address.
306  * @wr_table:     Optional, points to a struct regmap_access_table specifying
307  *                valid ranges for write access.
308  * @rd_table:     As above, for read access.
309  * @volatile_table: As above, for volatile registers.
310  * @precious_table: As above, for precious registers.
311  * @wr_noinc_table: As above, for no increment writeable registers.
312  * @rd_noinc_table: As above, for no increment readable registers.
313  * @reg_defaults: Power on reset values for registers (for use with
314  *                register cache support).
315  * @num_reg_defaults: Number of elements in reg_defaults.
316  *
317  * @read_flag_mask: Mask to be set in the top bytes of the register when doing
318  *                  a read.
319  * @write_flag_mask: Mask to be set in the top bytes of the register when doing
320  *                   a write. If both read_flag_mask and write_flag_mask are
321  *                   empty and zero_flag_mask is not set the regmap_bus default
322  *                   masks are used.
323  * @zero_flag_mask: If set, read_flag_mask and write_flag_mask are used even
324  *                   if they are both empty.
325  * @use_relaxed_mmio: If set, MMIO R/W operations will not use memory barriers.
326  *                    This can avoid load on devices which don't require strict
327  *                    orderings, but drivers should carefully add any explicit
328  *                    memory barriers when they may require them.
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
338  *
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
344  *                     DEFAULT, the @reg_format_endian_default value from the
345  *                     regmap bus is used.
346  * @val_format_endian: Endianness for formatted register values. If this is
347  *                     DEFAULT, the @reg_format_endian_default value from the
348  *                     regmap bus is used.
349  *
350  * @ranges: Array of configuration entries for virtual address ranges.
351  * @num_ranges: Number of range configuration entries.
352  * @use_hwlock: Indicate if a hardware spinlock should be used.
353  * @use_raw_spinlock: Indicate if a raw spinlock should be used.
354  * @hwlock_id: Specify the hardware spinlock id.
355  * @hwlock_mode: The hardware spinlock mode, should be HWLOCK_IRQSTATE,
356  *		 HWLOCK_IRQ or 0.
357  * @can_sleep: Optional, specifies whether regmap operations can sleep.

489  *
490  * @fast_io: Register IO is fast. Use a spinlock instead of a mutex
491  *	     to perform locking. This field is ignored if custom lock/unlock
492  *	     functions are used (see fields lock/unlock of
493  *	     struct regmap_config).
494  * @write: Write operation.
495  * @gather_write: Write operation with split register/value, return -ENOTSUPP
496  *                if not implemented  on a given device.
497  * @async_write: Write operation which completes asynchronously, optional and
498  *               must serialise with respect to non-async I/O.
499  * @reg_write: Write a single register value to the given register address. This
500  *             write operation has to complete when returning from the function.
501  * @reg_update_bits: Update bits operation to be used against volatile
502  *                   registers, intended for devices supporting some mechanism
503  *                   for setting clearing bits without having to
504  *                   read/modify/write.
505  * @read: Read operation.  Data is returned in the buffer used to transmit
506  *         data.
507  * @reg_read: Read a single register value from a given register address.
508  * @free_context: Free context.
509  * @async_alloc: Allocate a regmap_async() structure.
510  * @read_flag_mask: Mask to be set in the top byte of the register when doing
511  *                  a read.
512  * @reg_format_endian_default: Default endianness for formatted register
513  *     addresses. Used when the regmap_config specifies DEFAULT. If this is
514  *     DEFAULT, BIG is assumed.
515  * @val_format_endian_default: Default endianness for formatted register
516  *     values. Used when the regmap_config specifies DEFAULT. If this is
517  *     DEFAULT, BIG is assumed.
518  * @max_raw_read: Max raw read size that can be used on the bus.
519  * @max_raw_write: Max raw write size that can be used on the bus.
520  * @free_on_exit: kfree this on exit of regmap

1426  *		 ack_base.
1427  * @num_main_status_bits: Should be given to chips where number of meaningfull
1428  *			  main status bits differs from num_regs.
1429  * @sub_reg_offsets: arrays of mappings from main register bits to sub irq
1430  *		     registers. First item in array describes the registers
1431  *		     for first main status bit. Second array for second bit etc.
1432  *		     Offset is given as sub register status offset to

1464  *                   registers before unmasking interrupts to clear any bits
1465  *                   set when they were masked.
1466  * @not_fixed_stride: Used when chip peripherals are not laid out with fixed
