    I don't think this matters on any of the i.MX platforms, as the GPIO
    pin configuration (including open-drain) is only taken from the DT
    pinctrl, with the GPIO driver not being able to change any of those. On
    the flipside this results in a near zero probability of regressions.
    ;)

    As this is obviously right even if it doesn't have any effect on
    current software:
