282 * (e.g., a clear on read interrupt status register). If this
283 * field is NULL but precious_table (see below) is not, the

301 * all the reads from the registers. Should only be provided for
302 * devices whose read operation cannot be represented as a simple
303 * read operation on a bus such as SPI, I2C, etc. Most of the
304 * devices do not need this.
305 * @reg_write: Same as above for writing.
306 * @reg_update_bits: Optional callback that if filled will be used to perform
307 * all the update_bits(rmw) operation. Should only be provided
308 * if the function require special handling with lock and reg
309 * handling and the operation cannot be represented as a simple
310 * update_bits operation on a bus such as SPI, I2C, etc.
311 * @read: Optional callback that if filled will be used to perform all the
312 * bulk reads from the registers. Data is returned in the buffer used
313 * to transmit data.
314 * @write: Same as above for writing.
315 * @max_raw_read: Max raw read size that can be used on the device.
316 * @max_raw_write: Max raw write size that can be used on the device.
317 * @can_sleep: Optional, specifies whether regmap operations can sleep.
318 * @fast_io: Register IO is fast. Use a spinlock instead of a mutex
319 * to perform locking. This field is ignored if custom lock/unlock
320 * functions are used (see fields lock/unlock of struct regmap_config).
321 * This field is a duplicate of a similar file in
322 * 'struct regmap_bus' and serves exact same purpose.
323 * Use it only for "no-bus" cases.
324 * @io_port: Support IO port accessors. Makes sense only when MMIO vs. IO port
325 * access can be distinguished.
326 * @disable_locking: This regmap is either protected by external means or
327 * is guaranteed not to be accessed from multiple threads.
328 * Don't use any locking mechanisms.
329 * @lock: Optional lock callback (overrides regmap's default lock
330 * function, based on spinlock or mutex).
331 * @unlock: As above for unlocking.
332 * @lock_arg: This field is passed as the only argument of lock/unlock
333 * functions (ignored in case regular lock/unlock functions
334 * are not overridden).
335 * @max_register: Optional, specifies the maximum valid register address.
336 * @max_register_is_0: Optional, specifies that zero value in @max_register
337 * should be taken into account. This is a workaround to
338 * apply handling of @max_register for regmap that contains
339 * only one register.
340 * @wr_table: Optional, points to a struct regmap_access_table specifying
341 * valid ranges for write access.
342 * @rd_table: As above, for read access.
343 * @volatile_table: As above, for volatile registers.
344 * @precious_table: As above, for precious registers.
345 * @wr_noinc_table: As above, for no increment writeable registers.
346 * @rd_noinc_table: As above, for no increment readable registers.
347 * @reg_defaults: Power on reset values for registers (for use with
348 * register cache support).
349 * @num_reg_defaults: Number of elements in reg_defaults.
350 *
351 * @read_flag_mask: Mask to be set in the top bytes of the register when doing
352 * a read.
353 * @write_flag_mask: Mask to be set in the top bytes of the register when doing
354 * a write. If both read_flag_mask and write_flag_mask are
355 * empty and zero_flag_mask is not set the regmap_bus default
356 * masks are used.
357 * @zero_flag_mask: If set, read_flag_mask and write_flag_mask are used even
358 * if they are both empty.
359 * @use_relaxed_mmio: If set, MMIO R/W operations will not use memory barriers.
360 * This can avoid load on devices which don't require strict
361 * orderings, but drivers should carefully add any explicit
362 * memory barriers when they may require them.
363 * @use_single_read: If set, converts the bulk read operation into a series of
364 * single read operations. This is useful for a device that
365 * does not support bulk read.
366 * @use_single_write: If set, converts the bulk write operation into a series of
367 * single write operations. This is useful for a device that
368 * does not support bulk write.
369 * @can_multi_write: If set, the device supports the multi write mode of bulk
370 * write operations, if clear multi write requests will be
371 * split into individual write operations
372 *
373 * @cache_type: The actual cache type.
374 * @reg_defaults_raw: Power on reset values for registers (for use with
375 * register cache support).
376 * @num_reg_defaults_raw: Number of elements in reg_defaults_raw.
377 * @use_hwlock: Indicate if a hardware spinlock should be used.
378 * @use_raw_spinlock: Indicate if a raw spinlock should be used.
379 * @hwlock_id: Specify the hardware spinlock id.
380 * @hwlock_mode: The hardware spinlock mode, should be HWLOCK_IRQSTATE,
381 * HWLOCK_IRQ or 0.
382 * @reg_format_endian: Endianness for formatted register addresses. If this is
383 * DEFAULT, the @reg_format_endian_default value from the
384 * regmap bus is used.
385 * @val_format_endian: Endianness for formatted register values. If this is

532 *
533 * @fast_io: Register IO is fast. Use a spinlock instead of a mutex
534 * to perform locking. This field is ignored if custom lock/unlock
535 * functions are used (see fields lock/unlock of
536 * struct regmap_config).
537 * @free_on_exit: kfree this on exit of regmap
538 * @write: Write operation.
539 * @gather_write: Write operation with split register/value, return -ENOTSUPP
540 * if not implemented on a given device.
541 * @async_write: Write operation which completes asynchronously, optional and
542 * must serialise with respect to non-async I/O.
543 * @reg_write: Write a single register value to the given register address. This
544 * write operation has to complete when returning from the function.
545 * @reg_write_noinc: Write multiple register value to the same register. This
546 * write operation has to complete when returning from the function.
547 * @reg_update_bits: Update bits operation to be used against volatile
548 * registers, intended for devices supporting some mechanism
549 * for setting clearing bits without having to
550 * read/modify/write.
551 * @read: Read operation. Data is returned in the buffer used to transmit
552 * data.
553 * @reg_read: Read a single register value from a given register address.
554 * @free_context: Free context.
555 * @async_alloc: Allocate a regmap_async() structure.
556 * @read_flag_mask: Mask to be set in the top byte of the register when doing
557 * a read.
558 * @reg_format_endian_default: Default endianness for formatted register
559 * addresses. Used when the regmap_config specifies DEFAULT. If this is
560 * DEFAULT, BIG is assumed.
561 * @val_format_endian_default: Default endianness for formatted register
562 * values. Used when the regmap_config specifies DEFAULT. If this is
563 * DEFAULT, BIG is assumed.
564 * @max_raw_read: Max raw read size that can be used on the bus.
565 * @max_raw_write: Max raw write size that can be used on the bus.

1519 * struct regmap_irq_chip - Description of a generic regmap irq_chip.
1520 *
1521 * @name: Descriptive name for IRQ controller.
1522 *
1523 * @main_status: Base main status register address. For chips which have
1524 * interrupts arranged in separate sub-irq blocks with own IRQ
1525 * registers and which have a main IRQ registers indicating
1526 * sub-irq blocks with unhandled interrupts. For such chips fill
1527 * sub-irq register information in status_base, mask_base and
1528 * ack_base.
1529 * @num_main_status_bits: Should be given to chips where number of meaningfull
1530 * main status bits differs from num_regs.
1531 * @sub_reg_offsets: arrays of mappings from main register bits to sub irq
1532 * registers. First item in array describes the registers
1533 * for first main status bit. Second array for second bit etc.
1534 * Offset is given as sub register status offset to
1535 * status_base. Should contain num_regs arrays.
1536 * Can be provided for chips with more complex mapping than
1537 * 1.st bit to 1.st sub-reg, 2.nd bit to 2.nd sub-reg, ...
1538 * @num_main_regs: Number of 'main status' irq registers for chips which have
1539 * main_status set.
1540 *
1541 * @status_base: Base status register address.
1542 * @mask_base: Base mask register address. Mask bits are set to 1 when an
1543 * interrupt is masked, 0 when unmasked.
1544 * @unmask_base: Base unmask register address. Unmask bits are set to 1 when
1545 * an interrupt is unmasked and 0 when masked.
1546 * @ack_base: Base ack address. If zero then the chip is clear on read.
1547 * Using zero value is possible with @use_ack bit.
1548 * @wake_base: Base address for wake enables. If zero unsupported.
1549 * @config_base: Base address for IRQ type config regs. If null unsupported.
1550 * @irq_reg_stride: Stride to use for chips where registers are not contiguous.
1551 * @init_ack_masked: Ack all masked interrupts once during initalization.
1552 * @mask_unmask_non_inverted: Controls mask bit inversion for chips that set
1553 * both @mask_base and @unmask_base. If false, mask and unmask bits are
1554 * inverted (which is deprecated behavior); if true, bits will not be
1555 * inverted and the registers keep their normal behavior. Note that if
1556 * you use only one of @mask_base or @unmask_base, this flag has no
1557 * effect and is unnecessary. Any new drivers that set both @mask_base
1558 * and @unmask_base should set this to true to avoid relying on the
1559 * deprecated behavior.
1560 * @use_ack: Use @ack register even if it is zero.
1561 * @ack_invert: Inverted ack register: cleared bits for ack.
1562 * @clear_ack: Use this to set 1 and 0 or vice-versa to clear interrupts.
1563 * @status_invert: Inverted status register: cleared bits are active interrupts.
1564 * @wake_invert: Inverted wake register: cleared bits are wake enabled.
1565 * @type_in_mask: Use the mask registers for controlling irq type. Use this if
1566 * the hardware provides separate bits for rising/falling edge
1567 * or low/high level interrupts and they should be combined into
1568 * a single logical interrupt. Use &struct regmap_irq_type data
1569 * to define the mask bit for each irq type.
1570 * @clear_on_unmask: For chips with interrupts cleared on read: read the status
1571 * registers before unmasking interrupts to clear any bits
1572 * set when they were masked.
1573 * @runtime_pm: Hold a runtime PM lock on the device when accessing it.
1574 * @no_status: No status register: all interrupts assumed generated by device.
1575 *
1576 * @num_regs: Number of registers in each control bank.
1577 *
1578 * @irqs: Descriptors for individual IRQs. Interrupt numbers are
1579 * assigned based on the index in the array of the interrupt.
1580 * @num_irqs: Number of descriptors.
1581 * @num_config_bases: Number of config base registers.
1582 * @num_config_regs: Number of config registers for each config base register.
1583 *
1584 * @handle_pre_irq: Driver specific callback to handle interrupt from device
1585 * before regmap_irq_handler process the interrupts.
1586 * @handle_post_irq: Driver specific callback to handle interrupt from device
1587 * after handling the interrupts in regmap_irq_handler().
1588 * @handle_mask_sync: Callback used to handle IRQ mask syncs. The index will be
1589 * in the range [0, num_regs)
1590 * @set_type_config: Callback used for configuring irq types.
1591 * @get_irq_reg: Callback for mapping (base register, index) pairs to register
1592 * addresses. The base register will be one of @status_base,
1593 * @mask_base, etc., @main_status, or any of @config_base.
1594 * The index will be in the range [0, num_main_regs[ for the
1595 * main status base, [0, num_config_regs[ for any config
1596 * register base, and [0, num_regs[ for any other base.
1597 * If unspecified then regmap_irq_get_irq_reg_linear() is used.
1598 * @irq_drv_data: Driver specific IRQ data which is passed as parameter when
1599 * driver specific pre/post interrupt handler is called.
1600 *
1601 * This is not intended to handle every possible interrupt controller, but
1602 * it should handle a substantial proportion of those that are found in the
1603 * wild.
