THS8135 Video DAC
-----------------
This is the binding for Texas Instruments THS8135 Video DAC bridge.
Required properties:
- compatible: Must be "ti,ths8135"
Required nodes:
This device has two video ports. Their connections are modelled using the OF
graph bindings specified in Documentation/devicetree/bindings/graph.txt.
- Video port 0 for RGB input
- Video port 1 for VGA output
Example
-------
vga-bridge {
compatible = "ti,ths8135";
#address-cells = <1>;
#size-cells = <0>;
ports {
#address-cells = <1>;
#size-cells = <0>;
port@0 {
reg = <0>;
vga_bridge_in: endpoint {
remote-endpoint = <&lcdc_out_vga>;
};
};
port@1 {
reg = <1>;
vga_bridge_out: endpoint {
remote-endpoint = <&vga_con_in>;
};
};
};
};
