273 | * can be written to. If this field is NULL but wr_table | |
274 | * (see below) is not, the check is performed on such table | |
275 | * (a register is writeable if it belongs to one of the ranges | |
276 | * specified by wr_table). | |

289 | * (e.g., a clear on read interrupt status register). If this | |

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

1602 | * | |
1603 | * @main_status: Base main status register address. For chips which have | |
1604 | * interrupts arranged in separate sub-irq blocks with own IRQ | |
1605 | * registers and which have a main IRQ registers indicating | |
1606 | * sub-irq blocks with unhandled interrupts. For such chips fill | |

1614 | * Offset is given as sub register status offset to | |

1616 | * Can be provided for chips with more complex mapping than | |
1617 | * 1.st bit to 1.st sub-reg, 2.nd bit to 2.nd sub-reg, ... | |

1619 | * main_status set. | |
1620 | * | |
1621 | * @status_base: Base status register address. | |
1622 | * @mask_base: Base mask register address. Mask bits are set to 1 when an | |

1634 | * inverted (which is deprecated behavior); if true, bits will not be | |

1637 | * effect and is unnecessary. Any new drivers that set both @mask_base | |
1638 | * and @unmask_base should set this to true to avoid relying on the | |
1639 | * deprecated behavior. | |
1640 | * @use_ack: Use @ack register even if it is zero. | |

1642 | * @clear_ack: Use this to set 1 and 0 or vice-versa to clear interrupts. | |
1643 | * @status_invert: Inverted status register: cleared bits are active interrupts. | |
1644 | * @status_is_level: Status register is actuall signal level: Xor status | |
1645 | * register with previous value to get active interrupts. | |
1646 | * @wake_invert: Inverted wake register: cleared bits are wake enabled. | |
1647 | * @type_in_mask: Use the mask registers for controlling irq type. Use this if | |
1648 | * the hardware provides separate bits for rising/falling edge | |
1649 | * or low/high level interrupts and they should be combined into | |
1650 | * a single logical interrupt. Use &struct regmap_irq_type data | |
1651 | * to define the mask bit for each irq type. | |
1652 | * @clear_on_unmask: For chips with interrupts cleared on read: read the status | |
1653 | * registers before unmasking interrupts to clear any bits | |
1654 | * set when they were masked. | |
1655 | * @runtime_pm: Hold a runtime PM lock on the device when accessing it. | |
1656 | * @no_status: No status register: all interrupts assumed generated by device. | |
1657 | * | |
1658 | * @num_regs: Number of registers in each control bank. | |
1659 | * | |

1671 | * in the range [0, num_regs) | |
1672 | * @set_type_config: Callback used for configuring irq types. | |
1673 | * @get_irq_reg: Callback for mapping (base register, index) pairs to register | |
