    regulator: fixed/gpio: Pull inversion/OD into gpiolib · 01dc79cd
    Linus Walleij authored
    This pushes the handling of inversion semantics and open drain
    settings to the GPIO descriptor and gpiolib. All affected board
    files are also augmented.
    
    This is especially nice since we don't have to have any
    confusing flags passed around to the left and right littering
    the fixed and GPIO regulator drivers and the regulator core.
    It is all just very straight-forward: the core asks the GPIO
    line to be asserted or deasserted and gpiolib deals with the
    rest depending on how the platform is configured: if the line
    is active low, it deals with that, if the line is open drain,
    it deals with that too.
