pinctrl: generic: Add output-enable property
Add output-enable generic pin configuration property. This properties allows enabling/disabling pin's output capabilities without actually driving any value on the line. Acked-by: Rob Herring <robh@kernel.org> [Added inline elaborations on buffer enabling/disabling] Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
