296 * (a register is writeable if it belongs to one of the ranges

335 * functions (ignored in case regular lock/unlock functions

338 * all the reads from the registers. Should only be provided for
339 * devices whose read operation cannot be represented as a simple
340 * read operation on a bus such as SPI, I2C, etc. Most of the
341 * devices do not need this.
342 * @reg_write: Same as above for writing.
343 * @fast_io: Register IO is fast. Use a spinlock instead of a mutex
344 * to perform locking. This field is ignored if custom lock/unlock
345 * functions are used (see fields lock/unlock of struct regmap_config).
346 * This field is a duplicate of a similar file in
347 * 'struct regmap_bus' and serves exact same purpose.
348 * Use it only for "no-bus" cases.

351 * valid ranges for write access.

363 * @write_flag_mask: Mask to be set in the top bytes of the register when doing
364 * a write. If both read_flag_mask and write_flag_mask are
365 * empty and zero_flag_mask is not set the regmap_bus default
367 * @zero_flag_mask: If set, read_flag_mask and write_flag_mask are used even
368 * if they are both empty.
369 * @use_single_read: If set, converts the bulk read operation into a series of
370 * single read operations. This is useful for a device that
371 * does not support bulk read.
372 * @use_single_write: If set, converts the bulk write operation into a series of
373 * single write operations. This is useful for a device that
374 * does not support bulk write.
375 * @can_multi_write: If set, the device supports the multi write mode of bulk
376 * write operations, if clear multi write requests will be
377 * split into individual write operations

384 * DEFAULT, the @reg_format_endian_default value from the
385 * regmap bus is used.
386 * @val_format_endian: Endianness for formatted register values. If this is
387 * DEFAULT, the @reg_format_endian_default value from the

1210 * interrupts arranged in separate sub-irq blocks with own IRQ
1211 * registers and which have a main IRQ registers indicating
1212 * sub-irq blocks with unhandled interrupts. For such chips fill

1215 * @num_main_status_bits: Should be given to chips where number of meaningfull
1216 * main status bits differs from num_regs.
1217 * @sub_reg_offsets: arrays of mappings from main register bits to sub irq
1218 * registers. First item in array describes the registers
1219 * for first main status bit. Second array for second bit etc.
1220 * Offset is given as sub register status offset to
1221 * status_base. Should contain num_regs arrays.
1222 * Can be provided for chips with more complex mapping than
1223 * 1.st bit to 1.st sub-reg, 2.nd bit to 2.nd sub-reg, ...

1227 * @status_base: Base status register address.
1228 * @mask_base: Base mask register address.
1229 * @mask_writeonly: Base mask register is write only.
1230 * @unmask_base: Base unmask register address. for chips who have
1231 * separate mask and unmask registers
1232 * @ack_base: Base ack address. If zero then the chip is clear on read.
1233 * Using zero value is possible with @use_ack bit.
1234 * @wake_base: Base address for wake enables. If zero unsupported.
1235 * @type_base: Base address for irq type. If zero unsupported.
1236 * @irq_reg_stride: Stride to use for chips where registers are not contiguous.
1237 * @init_ack_masked: Ack all masked interrupts once during initalization.
1238 * @mask_invert: Inverted mask register: cleared bits are masked out.
1239 * @use_ack: Use @ack register even if it is zero.
1240 * @ack_invert: Inverted ack register: cleared bits for ack.
1241 * @wake_invert: Inverted wake register: cleared bits are wake enabled.
1242 * @type_invert: Invert the type flags.
1243 * @type_in_mask: Use the mask registers for controlling irq type. For
1244 * interrupts defining type_rising/falling_mask use mask_base
1245 * for edge configuration and never update bits in type_base.
1246 * @clear_on_unmask: For chips with interrupts cleared on read: read the status
1247 * registers before unmasking interrupts to clear any bits
1248 * set when they were masked.
1249 * @runtime_pm: Hold a runtime PM lock on the device when accessing it.
1251 * @num_regs: Number of registers in each control bank.
1252 * @irqs: Descriptors for individual IRQs. Interrupt numbers are
1253 * assigned based on the index in the array of the interrupt.
1254 * @num_irqs: Number of descriptors.
1255 * @num_type_reg: Number of type registers.
1256 * @type_reg_stride: Stride to use for chips where type registers are not
1258 * @handle_pre_irq: Driver specific callback to handle interrupt from device
1259 * before regmap_irq_handler process the interrupts.
1260 * @handle_post_irq: Driver specific callback to handle interrupt from device
1261 * after handling the interrupts in regmap_irq_handler().
1262 * @irq_drv_data: Driver specific IRQ data which is passed as parameter when
1263 * driver specific pre/post interrupt handler is called.
1265 * This is not intended to handle every possible interrupt controller, but
1266 * it should handle a substantial proportion of those that are found in the
