^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12) - compatible: Should be one of:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13) 	- "x-powers,axp209-gpio"
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14) 	- "x-powers,axp813-gpio"
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15) - #gpio-cells: Should be two. The first cell is the pin number and the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 16)   second is the GPIO flags.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17) - gpio-controller: Marks the device node as a GPIO controller.
