 *              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.
 * @readable_reg: Optional callback returning true if the register
 *                can be read from.
 * @volatile_reg: Optional callback returning true if the register
 *                value can't be cached.
 * @precious_reg: Optional callback returning true if the rgister
 *                should not be read outside of a call from the driver
 *                (eg, a clear on read interrupt status register).
 *
 * @max_register: Optional, specifies the maximum valid register index.
 * @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.
 *
 * @cache_type: The actual cache type.
