    gpio: vx855: use the new open drain callback · 640b9135
    Linus Walleij authored
    The vx855 driver clearly states it has three groups of lines:
    GPI, GPO and GPIO. The GPO are assumedly push-pull. The GPIO
    are implicit open drain, but if the GPIO subsystem ask for them
    to be explicitly open drain (i.e. set the flag on a machine table
    that we want open drain) it will currently misbehave: it will
    switch the GPIOs to input mode (emulate open drain). Instead:
    indicate in the .set_single_ended() callback that we support
    open drain and open drain only.
