parentleds: leds-gpio: Add support for GPIO descriptors (diff)
input: gpio_keys_polled: Add support for GPIO descriptors
GPIO descriptors are the preferred way over legacy GPIO numbers nowadays. Convert the driver to use GPIO descriptors internally but still allow passing legacy GPIO numbers from platform data to support existing platforms.
