    regmap: Add a reusable irq_chip for regmap based interrupt controllers · f8beab2b
    Mark Brown authored
    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.
