1Video Multiplexer 2================= 3 4Video multiplexers allow to select between multiple input ports. Video received 5on the active input port is passed through to the output port. Muxes described 6by this binding are controlled by a multiplexer controller that is described by 7the bindings in Documentation/devicetree/bindings/mux/mux-controller.txt 8 9Required properties: 10- compatible : should be "video-mux" 11- mux-controls : mux controller node to use for operating the mux 12- #address-cells: should be <1> 13- #size-cells: should be <0> 14- port@*: at least three port nodes containing endpoints connecting to the 15 source and sink devices according to of_graph bindings. The last port is 16 the output port, all others are inputs. 17 18Optionally, #address-cells, #size-cells, and port nodes can be grouped under a 19ports node as described in Documentation/devicetree/bindings/graph.txt. 20 21Example: 22 23 mux: mux-controller { 24 compatible = "gpio-mux"; 25 #mux-control-cells = <0>; 26 27 mux-gpios = <&gpio1 15 GPIO_ACTIVE_HIGH>; 28 }; 29 30 video-mux { 31 compatible = "video-mux"; 32 mux-controls = <&mux>; 33 #address-cells = <1>; 34 #size-cells = <0>; 35 36 port@0 { 37 reg = <0>; 38 39 mux_in0: endpoint { 40 remote-endpoint = <&video_source0_out>; 41 }; 42 }; 43 44 port@1 { 45 reg = <1>; 46 47 mux_in1: endpoint { 48 remote-endpoint = <&video_source1_out>; 49 }; 50 }; 51 52 port@2 { 53 reg = <2>; 54 55 mux_out: endpoint { 56 remote-endpoint = <&capture_interface_in>; 57 }; 58 }; 59 }; 60}; 61
