+Video Multiplexer
+=================
+
+Video multiplexers allow to select between multiple input ports. Video received
+on the active input port is passed through to the output port. Muxes described
+by this binding are controlled by a multiplexer controller that is described by
+the bindings in Documentation/devicetree/bindings/mux/mux-controller.txt
+
+Required properties:
+- compatible : should be "video-mux"
+- mux-controls : mux controller node to use for operating the mux
+- #address-cells: should be <1>
+- #size-cells: should be <0>
+- port@*: at least three port nodes containing endpoints connecting to the
+ source and sink devices according to of_graph bindings. The last port is
+ the output port, all others are inputs.
+
+Optionally, #address-cells, #size-cells, and port nodes can be grouped under a
+ports node as described in Documentation/devicetree/bindings/graph.txt.
+
+Example:
+
+ mux: mux-controller {
+ compatible = "gpio-mux";
+ #mux-control-cells = <0>;
+
+ mux-gpios = <&gpio1 15 GPIO_ACTIVE_HIGH>;
+ };
+
+ video-mux {
+ compatible = "video-mux";
+ mux-controls = <&mux>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ port@0 {
+ reg = <0>;
+
+ mux_in0: endpoint {
+ remote-endpoint = <&video_source0_out>;
+ };
+ };
+
+ port@1 {
+ reg = <1>;
+
+ mux_in1: endpoint {
+ remote-endpoint = <&video_source1_out>;
+ };
+ };
+
+ port@2 {
+ reg = <2>;
+
+ mux_out: endpoint {
+ remote-endpoint = <&capture_interface_in>;
+ };
+ };
+ };
+};
