-Zevio GPIO controller
-
-Required properties:
-- compatible: Should be "lsi,zevio-gpio"
-- reg: Address and length of the register set for the device
-- #gpio-cells: Should be two. The first cell is the pin number and the
-  second cell is used to specify optional parameters (currently unused).
-- gpio-controller: Marks the device node as a GPIO controller.

-Example:
-	gpio: gpio@...00000 {
-		compatible = "lsi,zevio-gpio";
-		reg = <0x90000000 0x1000>;
-		gpio-controller;
-		#gpio-cells = <2>;
