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"
Any encoder compatible with this generic binding, but with additional
properties not listed here, must list a device specific compatible first
followed by this generic compatible.
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";
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>;
};
};
};
};
