Each button (key) is represented as a sub-node of "gpio-keys":

- linux,code: Keycode to emit.
Required mutual exclusive subnode-properties:
- gpios: OF device-tree gpio specification.
- interrupts: the interrupt line for that input
Note that either "interrupts" or "gpios" properties can be omitted, but not

- debounce-interval: Debouncing interval time in milliseconds.

- gpio-key,wakeup: Boolean, button can wake-up the system.
- linux,can-disable: Boolean, indicates that button is connected
to dedicated (not shared) interrupt which can be disabled to
suppress events from the button.
