I would like to limit (or maybe even remove) use of [devm_]gpiod_get_from_of_node in drivers so that gpiolib can be cleaned a bit, so let's switch to the generic device property API. It may even help with handling secondary fwnodes when gpiolib is taught to handle gpios described by swnodes. Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
