All zero read and write masks in the regmap config are used to signal no special mask is needed and the bus defaults are used. In some devices all zero read/write masks are the special mask and bus defaults should not be used. To signal this a new variable is added. For example SPI often sets bit 7 in address to signal to the device a read is requested. On TI AFE44xx parts with SPI interfaces no bit needs to be set as registers are either read or write only and the operation can be determined from the address only. For this case both masks must be zero to not effect the address. Signed-off-by: Andrew F. Davis <afd@ti.com> Signed-off-by: Mark Brown <broonie@kernel.org> |
