+Lantiq Falon SoC GPIO controller bindings
+
+Required properties:
+- compatible:
+ - "lantiq,falcon-gpio" for Falcon SoC controllers
+- #gpio-cells : Should be two.
+ - first cell is the pin number
+ - second cell is used to specify optional parameters (unused)
+- gpio-controller : Marks the device node as a GPIO controller
+- reg : Physical base address and length of the controller's registers
+- interrupt-parent: phandle to the IM device node that the irq is routed via
+- interrupts : Specify the IM interrupt number
+- lantiq,bank : The physical GPIO bank that this block is assiciated with
+
+Example:
+
+ gpio0: gpio@810000 {
+ compatible = "lantiq,falcon-gpio";
+ #gpio-cells = <2>;
+ gpio-controller;
+ reg = <0x810000 0x80>;
+ interrupt-parent = <&icu0>;
+ interrupts = <44>;
+ lantiq,bank = <0>;
+ };
