Dumb RGB to VGA DAC bridge
|
|
---------------------------
|
|
|
|
This binding is aimed for dumb RGB to VGA DAC based bridges that do not require
|
|
any configuration.
|
|
|
|
Required properties:
|
|
|
|
- compatible: Must be "dumb-vga-dac"
|
|
|
|
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
|
|
|
|
Optional properties:
|
|
- vdd-supply: Power supply for DAC
|
|
|
|
Example
|
|
-------
|
|
|
|
bridge {
|
|
compatible = "dumb-vga-dac";
|
|
#address-cells = <1>;
|
|
#size-cells = <0>;
|
|
|
|
ports {
|
|
#address-cells = <1>;
|
|
#size-cells = <0>;
|
|
|
|
port@0 {
|
|
reg = <0>;
|
|
|
|
vga_bridge_in: endpoint {
|
|
remote-endpoint = <&tcon0_out_vga>;
|
|
};
|
|
};
|
|
|
|
port@1 {
|
|
reg = <1>;
|
|
|
|
vga_bridge_out: endpoint {
|
|
remote-endpoint = <&vga_con_in>;
|
|
};
|

};
