^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 2)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3) Required properties:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 4) - compatible: Should be "lsi,zevio-gpio"
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 5) - reg: Address and length of the register set for the device
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 6) - #gpio-cells: Should be two. The first cell is the pin number and the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 7) second cell is used to specify optional parameters (currently unused).
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 8) - gpio-controller: Marks the device node as a GPIO controller.
