regmap: irq: Add mask invert flag for enable register
Currently, regmap will write 1 to mask_base to mask an interrupt and write 0 to unmask it. But some chips do not have an interrupt mask register, and only have interrupt enable register. Then we should write 0 to disable interrupt and 1 to enable. So add an mask_invert flag to handle this. If it is not set, behavior is same as previous. If set it to 1, the mask value will be inverted before written to mask_base Signed-off-by: Xiaofan Tian <tianxf@marvell.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
