devicetree/bindings: display: bridge: Add LVDS encoder DT bindings

Parallel to LVDS Encoder

------------------------

This binding supports the parallel to LVDS encoders that don't require any

configuration.

LVDS is a physical layer specification defined in ANSI/TIA/EIA-644-A. Multiple

incompatible data link layers have been used over time to transmit image data

to LVDS panels. This binding targets devices compatible with the following

specifications only.

[JEIDA] "Digital Interface Standards for Monitor", JEIDA-59-1999, February

1999 (Version 1.0), Japan Electronic Industry Development Association (JEIDA)

[LDI] "Open LVDS Display Interface", May 1999 (Version 0.95), National

Semiconductor

[VESA] "VESA Notebook Panel Standard", October 2007 (Version 1.0), Video

Electronics Standards Association (VESA)

Those devices have been marketed under the FPD-Link and FlatLink brand names

among others.

Required properties:

- compatible: Must be "lvds-encoder"

Required nodes:

This device has two video ports. Their connections are modeled using the OF

graph bindings specified in Documentation/devicetree/bindings/graph.txt.

- Video port 0 for parallel input

- Video port 1 for LVDS output

Example

-------

lvds-encoder {

	compatible = "lvds-encoder";

	#address-cells = <1>;

	#size-cells = <0>;

	ports {

		#address-cells = <1>;

		#size-cells = <0>;

		port@0 {

			reg = <0>;

			lvds_enc_in: endpoint {

				remote-endpoint = <&display_out_rgb>;

			};

		};

		port@1 {

			reg = <1>;

			lvds_enc_out: endpoint {

				remote-endpoint = <&lvds_panel_in>;

			};

		};

	};

};
