+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@90000000 {
+ compatible = "lsi,zevio-gpio";
+ reg = <0x90000000 0x1000>;
+ gpio-controller;
+ #gpio-cells = <2>;
+ };
