    ASoC: rt5677: clear interrupts by polarity flip · 4f7b018b
    Ben Zhang authored
    The rt5677 jack detection function has a requirement that the polarity
    of an interrupt be flipped after it fires in order to clear the
    interrupt.
    
    This patch implements an irq_chip with irq_domain directly instead of
    using regmap-irq, so that interrupt source line polarities can be
    flipped in the irq handler.
    
    The reason that this patch does not add this feature within regmap-irq
    is that future patches will add hotword detection support to this irq
    handler. Those patches will require adding additional logic that would
    not make sense to have in regmap-irq.
