Turris Mox Moxtet GPIO expander via Moxtet bus



Required properties:

 - compatible		: Should be "cznic,moxtet-gpio".

 - gpio-controller	: Marks the device node as a GPIO controller.

 - #gpio-cells		: Should be two. For consumer use see gpio.txt.



Other properties are required for a Moxtet bus device, please refer to

Documentation/devicetree/bindings/bus/moxtet.txt.



Example:



	moxtet_sfp: gpio@0 {

		compatible = "cznic,moxtet-gpio";

		gpio-controller;

		#gpio-cells = <2>;

		reg = <0>;

	}
