/**
|
|
* Configuration for the register map of a device.
|
|
*
|
|
* @name: Optional name of the regmap. Useful when a device has multiple
|
|
* register regions.
|
|
*
|
|
* @reg_bits: Number of bits in a register address, mandatory.
|
|
* @reg_stride: The register address stride. Valid register addresses are a
|
|
* multiple of this value. If set to 0, a value of 1 will be
|
|
* used.
|
|
* @pad_bits: Number of bits of padding between register and value.
|
|
* @val_bits: Number of bits in a register value, mandatory.
|
|
*
|
|
* @writeable_reg: Optional callback returning true if the register
|
|
* can be written to. If this field is NULL but wr_table
|
|
* (see below) is not, the check is performed on such table
|
|
* (a register is writeable if it belongs to one of the ranges
|
|
* specified by wr_table).
|
|
* @readable_reg: Optional callback returning true if the register
|
|
* can be read from. If this field is NULL but rd_table
|
|
* (see below) is not, the check is performed on such table
|
|
* (a register is readable if it belongs to one of the ranges
|
|
* specified by rd_table).
|
|
* @volatile_reg: Optional callback returning true if the register
|
|
* value can't be cached. If this field is NULL but
|
|
* volatile_table (see below) is not, the check is performed on
|
|
* such table (a register is volatile if it belongs to one of
|
|
* the ranges specified by volatile_table).
|
|
* @precious_reg: Optional callback returning true if the register
|
|
* should not be read outside of a call from the driver
|
|
* (e.g., a clear on read interrupt status register). If this
|
|
* field is NULL but precious_table (see below) is not, the
|
|
* check is performed on such table (a register is precious if
|
|
* it belongs to one of the ranges specified by precious_table).
|
|
* @lock: Optional lock callback (overrides regmap's default lock
|
|
* function, based on spinlock or mutex).
|
|
* @unlock: As above for unlocking.
|
|
* @lock_arg: this field is passed as the only argument of lock/unlock
|
|
* functions (ignored in case regular lock/unlock functions
|
|
* are not overridden).
|
|
* @reg_read: Optional callback that if filled will be used to perform
|
|
* all the reads from the registers. Should only be provided for
|
|
* devices whose read operation cannot be represented as a simple
|
|
* read operation on a bus such as SPI, I2C, etc. Most of the
|
|
* devices do not need this.
|
|
* @reg_write: Same as above for writing.
|
|
* @fast_io: Register IO is fast. Use a spinlock instead of a mutex
|
|
* to perform locking. This field is ignored if custom lock/unlock
|
|
* functions are used (see fields lock/unlock of struct regmap_config).
|
|
* This field is a duplicate of a similar file in
|
|
* 'struct regmap_bus' and serves exact same purpose.
|
|
* Use it only for "no-bus" cases.
|
|
* @max_register: Optional, specifies the maximum valid register index.
|
|
* @wr_table: Optional, points to a struct regmap_access_table specifying
|
|
* valid ranges for write access.
|
|
* @rd_table: As above, for read access.
|
|
* @volatile_table: As above, for volatile registers.
|
|
* @precious_table: As above, for precious registers.
|
|
* @reg_defaults: Power on reset values for registers (for use with
|
|
* register cache support).
|
|
* @num_reg_defaults: Number of elements in reg_defaults.
|
|
*
|
|
* @read_flag_mask: Mask to be set in the top byte of the register when doing
|
|
* a read.
|
|
* @write_flag_mask: Mask to be set in the top byte of the register when doing
|
|
* a write. If both read_flag_mask and write_flag_mask are
|
|
* empty the regmap_bus default masks are used.
|
|
* @use_single_rw: If set, converts the bulk read and write operations into
|
|
* a series of single read and write operations. This is useful
|
|
* for device that does not support bulk read and write.
|
|
* @can_multi_write: If set, the device supports the multi write mode of bulk
|
|
* write operations, if clear multi write requests will be
|
|
* split into individual write operations
|
|
*
|
|
* @cache_type: The actual cache type.
|
|
* @reg_defaults_raw: Power on reset values for registers (for use with
|
|
* register cache support).
|
|
* @num_reg_defaults_raw: Number of elements in reg_defaults_raw.
|
|
* @reg_format_endian: Endianness for formatted register addresses. If this is
|
|
* DEFAULT, the @reg_format_endian_default value from the
|
|
* regmap bus is used.
|
|
* @val_format_endian: Endianness for formatted register values. If this is
|
|
* DEFAULT, the @reg_format_endian_default value from the
|
|
* regmap bus is used.
|
|
*
|
|
* @ranges: Array of configuration entries for virtual address ranges.
|
|
* @num_ranges: Number of range configuration entries.
