1Parallel to LVDS Encoder
2------------------------
3
4This binding supports the parallel to LVDS encoders that don't require any
5configuration.
6
7LVDS is a physical layer specification defined in ANSI/TIA/EIA-644-A. Multiple
8incompatible data link layers have been used over time to transmit image data
9to LVDS panels. This binding targets devices compatible with the following
10specifications only.
11
12[JEIDA] "Digital Interface Standards for Monitor", JEIDA-59-1999, February
131999 (Version 1.0), Japan Electronic Industry Development Association (JEIDA)
14[LDI] "Open LVDS Display Interface", May 1999 (Version 0.95), National
15Semiconductor
16[VESA] "VESA Notebook Panel Standard", October 2007 (Version 1.0), Video
17Electronics Standards Association (VESA)
18
19Those devices have been marketed under the FPD-Link and FlatLink brand names
20among others.

23Required properties:
24
25- compatible: Must be "lvds-encoder"
26
27 Any encoder compatible with this generic binding, but with additional
28 properties not listed here, must list a device specific compatible first
29 followed by this generic compatible.
30
31Required nodes:
32
33This device has two video ports. Their connections are modeled using the OF
34graph bindings specified in Documentation/devicetree/bindings/graph.txt.
35
36- Video port 0 for parallel input
37- Video port 1 for LVDS output
