Kernel-4.18.0-80.el8_lvds-transmitter

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>;
        };
    };
};

};
