    mmc: dt: pwrseq-simple: Invent power-off-delay-us · c477ebe2
    Ulf Hansson authored
    During power off, after the GPIO pin has been asserted, some devices like
    the Wifi chip from TI, Wl18xx, needs a delay before the host continues with
    clock gating and turning off regulators as to follow a graceful shutdown
    Therefore invent an optional power-off-delay-us DT binding for
    mmc-pwrseq-simple, to allow us to support this constraint.
