There seem to be lots of regmap-using devices with very similar interrupt controllers with a small bank of interrupt registers and mask registers with an interrupt per bit. This won't cover everything but it's a good start. Each chip supplies a base for the status registers, a base for the mask registers, an optional base for writing acknowledgements (which may be the same as the status registers) and an array of bits within each of these register banks which indicate the interrupt. There is an assumption that the bit for each interrupt will be the same in each of the register bank. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
