240 * @val_bits: Number of bits in a register value, mandatory.

244 * (see below) is not, the check is performed on such table
245 * (a register is writeable if it belongs to one of the ranges
246 * specified by wr_table).

253 * value can't be cached. If this field is NULL but

258 * should not be read outside of a call from the driver

271 * supports multiple read operations without incrementing
272 * the register number. If this field is NULL but

277 * @disable_locking: This regmap is either protected by external means or
278 * is guaranteed not to be accessed from multiple threads.
279 * Don't use any locking mechanisms.
280 * @lock: Optional lock callback (overrides regmap's default lock
281 * function, based on spinlock or mutex).
282 * @unlock: As above for unlocking.
283 * @lock_arg: this field is passed as the only argument of lock/unlock
284 * functions (ignored in case regular lock/unlock functions
285 * are not overridden).
286 * @reg_read: Optional callback that if filled will be used to perform
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 * @fast_io: Register IO is fast. Use a spinlock instead of a mutex
293 * to perform locking. This field is ignored if custom lock/unlock
294 * functions are used (see fields lock/unlock of struct regmap_config).
295 * This field is a duplicate of a similar file in
296 * 'struct regmap_bus' and serves exact same purpose.
297 * Use it only for "no-bus" cases.
298 * @max_register: Optional, specifies the maximum valid register address.
299 * @wr_table: Optional, points to a struct regmap_access_table specifying
300 * valid ranges for write access.
301 * @rd_table: As above, for read access.
302 * @volatile_table: As above, for volatile registers.
303 * @precious_table: As above, for precious registers.

307 * register cache support).

310 * @read_flag_mask: Mask to be set in the top bytes of the register when doing
312 * @write_flag_mask: Mask to be set in the top bytes of the register when doing
313 * a write. If both read_flag_mask and write_flag_mask are
314 * empty and zero_flag_mask is not set the regmap_bus default
316 * @zero_flag_mask: If set, read_flag_mask and write_flag_mask are used even
317 * if they are both empty.
318 * @use_single_read: If set, converts the bulk read operation into a series of
319 * single read operations. This is useful for a device that
320 * does not support bulk read.
321 * @use_single_write: If set, converts the bulk write operation into a series of
322 * single write operations. This is useful for a device that
323 * does not support bulk write.
324 * @can_multi_write: If set, the device supports the multi write mode of bulk
325 * write operations, if clear multi write requests will be
326 * split into individual write operations
328 * @cache_type: The actual cache type.
329 * @reg_defaults_raw: Power on reset values for registers (for use with
330 * register cache support).
331 * @num_reg_defaults_raw: Number of elements in reg_defaults_raw.
332 * @reg_format_endian: Endianness for formatted register addresses. If this is
333 * DEFAULT, the @reg_format_endian_default value from the
334 * regmap bus is used.
335 * @val_format_endian: Endianness for formatted register values. If this is
336 * DEFAULT, the @reg_format_endian_default value from the
337 * regmap bus is used.
339 * @ranges: Array of configuration entries for virtual address ranges.
340 * @num_ranges: Number of range configuration entries.
341 * @use_hwlock: Indicate if a hardware spinlock should be used.
342 * @hwlock_id: Specify the hardware spinlock id.

1294 * @status_base: Base status register address.
1295 * @mask_base: Base mask register address.
1296 * @mask_writeonly: Base mask register is write only.
1297 * @unmask_base: Base unmask register address. for chips who have
1298 * separate mask and unmask registers
1299 * @ack_base: Base ack address. If zero then the chip is clear on read.
1300 * Using zero value is possible with @use_ack bit.
1301 * @wake_base: Base address for wake enables. If zero unsupported.
1302 * @type_base: Base address for irq type. If zero unsupported.
1303 * @irq_reg_stride: Stride to use for chips where registers are not contiguous.
1304 * @init_ack_masked: Ack all masked interrupts once during initalization.
1305 * @mask_invert: Inverted mask register: cleared bits are masked out.
1306 * @use_ack: Use @ack register even if it is zero.
1307 * @ack_invert: Inverted ack register: cleared bits for ack.
1308 * @wake_invert: Inverted wake register: cleared bits are wake enabled.
1309 * @type_invert: Invert the type flags.
1310 * @type_in_mask: Use the mask registers for controlling irq type. For
1311 * interrupts defining type_rising/falling_mask use mask_base
1312 * for edge configuration and never update bits in type_base.
1313 * @clear_on_unmask: For chips with interrupts cleared on read: read the status
1314 * registers before unmasking interrupts to clear any bits
1315 * set when they were masked.
1316 * @runtime_pm: Hold a runtime PM lock on the device when accessing it.
1318 * @num_regs: Number of registers in each control bank.
1319 * @irqs: Descriptors for individual IRQs. Interrupt numbers are
1320 * assigned based on the index in the array of the interrupt.
1321 * @num_irqs: Number of descriptors.
1322 * @num_type_reg: Number of type registers.
1323 * @type_reg_stride: Stride to use for chips where type registers are not
1325 * @handle_pre_irq: Driver specific callback to handle interrupt from device
1326 * before regmap_irq_handler process the interrupts.
1327 * @handle_post_irq: Driver specific callback to handle interrupt from device
1328 * after handling the interrupts in regmap_irq_handler().
1329 * @irq_drv_data: Driver specific IRQ data which is passed as parameter when
1330 * driver specific pre/post interrupt handler is called.
1332 * This is not intended to handle every possible interrupt controller, but
1333 * it should handle a substantial proportion of those that are found in the
