7 title: Transparent LVDS encoders and decoders
10   - Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>
13   This binding supports transparent LVDS encoders and decoders that don't
16   LVDS is a physical layer specification defined in ANSI/TIA/EIA-644-A. Multiple
17   incompatible data link layers have been used over time to transmit image data
18   to LVDS panels. This binding targets devices compatible with the following
21   [JEIDA] "Digital Interface Standards for Monitor", JEIDA-59-1999, February
23   [LDI] "Open LVDS Display Interface", May 1999 (Version 0.95), National
28   Those devices have been marketed under the FPD-Link and FlatLink brand names
