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>;
|
||||
};
|
||||
};
|
||||
};
|
