+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: moxtet-sfp@0 {
+ compatible = "cznic,moxtet-gpio";
+ gpio-controller;
+ #gpio-cells = <2>;
+ reg = <0>;
+ }
