|
| 311 | * devices whose read operation cannot be represented as a simple

| 312 | * read operation on a bus such as SPI, I2C, etc. Most of the

|
| 314 | * @reg_write: Same as above for writing.
|
| 315 | * @reg_update_bits: Optional callback that if filled will be used to perform
|
| 316 | * all the update_bits(rmw) operation. Should only be provided

|
| 318 | * handling and the operation cannot be represented as a simple

|
| 325 | * @max_raw_write: Max raw write size that can be used on the device.
|
| 326 | * @fast_io: Register IO is fast. Use a spinlock instead of a mutex
|
| 327 | * to perform locking. This field is ignored if custom lock/unlock
|
| 328 | * functions are used (see fields lock/unlock of struct regmap_config).

|
| 330 | * 'struct regmap_bus' and serves exact same purpose.
|
| 331 | * Use it only for "no-bus" cases.
|
| 332 | * @io_port: Support IO port accessors. Makes sense only when MMIO vs. IO port
|
| 333 | * access can be distinguished.
|
| 334 | * @max_register: Optional, specifies the maximum valid register address.
|
| 335 | * @wr_table: Optional, points to a struct regmap_access_table specifying

|
| 337 | * @rd_table: As above, for read access.
|
| 338 | * @volatile_table: As above, for volatile registers.

|
| 346 | * @read_flag_mask: Mask to be set in the top bytes of the register when doing
|
| 347 | * a read.
|
| 348 | * @write_flag_mask: Mask to be set in the top bytes of the register when doing
|
| 349 | * a write. If both read_flag_mask and write_flag_mask are
|
| 350 | * empty and zero_flag_mask is not set the regmap_bus default
|
| 351 | * masks are used.
|
| 352 | * @zero_flag_mask: If set, read_flag_mask and write_flag_mask are used even
|
| 353 | * if they are both empty.
|
| 354 | * @use_relaxed_mmio: If set, MMIO R/W operations will not use memory barriers.
|
| 355 | * This can avoid load on devices which don't require strict
|
| 356 | * orderings, but drivers should carefully add any explicit
|
| 357 | * memory barriers when they may require them.
|
| 358 | * @use_single_read: If set, converts the bulk read operation into a series of
|
| 359 | * single read operations. This is useful for a device that
|
| 360 | * does not support bulk read.
|
| 361 | * @use_single_write: If set, converts the bulk write operation into a series of
|
| 362 | * single write operations. This is useful for a device that
|
| 363 | * does not support bulk write.
|
| 364 | * @can_multi_write: If set, the device supports the multi write mode of bulk
|
| 365 | * write operations, if clear multi write requests will be
|
| 366 | * split into individual write operations
|
| 367 | *
|
| 368 | * @cache_type: The actual cache type.
|
| 369 | * @reg_defaults_raw: Power on reset values for registers (for use with

|
| 371 | * @num_reg_defaults_raw: Number of elements in reg_defaults_raw.
|

| 374 | * regmap bus is used.
|
| 375 | * @val_format_endian: Endianness for formatted register values. If this is

| 377 | * regmap bus is used.
|
| 378 | *
|
| 379 | * @ranges: Array of configuration entries for virtual address ranges.

| 1559 | * @type_in_mask: Use the mask registers for controlling irq type. Use this if
|
| 1560 | * the hardware provides separate bits for rising/falling edge
|
| 1561 | * or low/high level interrupts and they should be combined into
|
| 1562 | * a single logical interrupt. Use &struct regmap_irq_type data
|
| 1563 | * to define the mask bit for each irq type.
|
| 1564 | * @clear_on_unmask: For chips with interrupts cleared on read: read the status
|
| 1565 | * registers before unmasking interrupts to clear any bits
|
| 1566 | * set when they were masked.
|
| 1567 | * @runtime_pm: Hold a runtime PM lock on the device when accessing it.
|
| 1568 | * @no_status: No status register: all interrupts assumed generated by device.
|
| 1569 | *
|
| 1570 | * @num_regs: Number of registers in each control bank.
|
| 1571 | *
|
| 1572 | * @irqs: Descriptors for individual IRQs. Interrupt numbers are
|
| 1573 | * assigned based on the index in the array of the interrupt.
|
| 1574 | * @num_irqs: Number of descriptors.
|
| 1575 | * @num_config_bases: Number of config base registers.
|
| 1576 | * @num_config_regs: Number of config registers for each config base register.
|
| 1577 | *
|
| 1578 | * @handle_pre_irq: Driver specific callback to handle interrupt from device
|
| 1579 | * before regmap_irq_handler process the interrupts.
|
| 1580 | * @handle_post_irq: Driver specific callback to handle interrupt from device
|
| 1581 | * after handling the interrupts in regmap_irq_handler().
|
| 1582 | * @handle_mask_sync: Callback used to handle IRQ mask syncs. The index will be
|
| 1583 | * in the range [0, num_regs)
|
| 1584 | * @set_type_config: Callback used for configuring irq types.
|
| 1585 | * @get_irq_reg: Callback for mapping (base register, index) pairs to register
|
| 1586 | * addresses. The base register will be one of @status_base,
|
| 1587 | * @mask_base, etc., @main_status, or any of @config_base.
|
| 1588 | * The index will be in the range [0, num_main_regs[ for the
|
| 1589 | * main status base, [0, num_config_regs[ for any config
|
| 1590 | * register base, and [0, num_regs[ for any other base.
|
| 1591 | * If unspecified then regmap_irq_get_irq_reg_linear() is used.
|
| 1592 | * @irq_drv_data: Driver specific IRQ data which is passed as parameter when
|
| 1593 | * driver specific pre/post interrupt handler is called.
|
| 1594 | *
|
| 1595 | * This is not intended to handle every possible interrupt controller, but
|
| 1596 | * it should handle a substantial proportion of those that are found in the
|
| 1597 | * wild.
