+Axis ETRAX FS General I/O controller bindings
+
+Required properties:
+
+- compatible:
+ - "axis,etraxfs-gio"
+- reg: Physical base address and length of the controller's registers.
+- #gpio-cells: Should be 3
+ - The first cell is the gpio offset number.
+ - The second cell is reserved and is currently unused.
+ - The third cell is the port number (hex).
+- gpio-controller: Marks the device node as a GPIO controller.
+
+Example:
+
+ gio: gpio@b001a000 {
+ compatible = "axis,etraxfs-gio";
+ reg = <0xb001a000 0x1000>;
+ gpio-controller;
+ #gpio-cells = <3>;
+ };
