^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3) Required properties:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 4) - compatible : "sirf,atlas7-gpio"
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 5) - reg : Address range of the pinctrl registers
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 6) - interrupts : Interrupts used by every GPIO group
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 7) - gpio-banks : How many gpio banks on this controller
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 8) - gpio-controller : Indicates this device is a GPIO controller
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 9) - interrupt-controller : Marks the device node as an interrupt controller
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11) The GPIO controller also acts as an interrupt controller. It uses the default
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12) two cells specifier as described in Documentation/devicetree/bindings/
