14 LVDS is a physical layer specification defined in ANSI/TIA/EIA-644-A. Multiple
15 incompatible data link layers have been used over time to transmit image data
16 to LVDS devices. This bindings supports devices compatible with the following
19 [JEIDA] "Digital Interface Standards for Monitor", JEIDA-59-1999, February
20 1999 (Version 1.0), Japan Electronic Industry Development Association (JEIDA)
21 [LDI] "Open LVDS Display Interface", May 1999 (Version 0.95), National
23 [VESA] "VESA Notebook Panel Standard", October 2007 (Version 1.0), Video
24 Electronics Standards Association (VESA)
26 Device compatible with those specifications have been marketed under the
27 FPD-Link and FlatLink brands.
36 The color signals mapping order.
38 LVDS data mappings are defined as follows.
40 - "jeida-18" - 18-bit data mapping compatible with the [JEIDA], [LDI] and
41 [VESA] specifications. Data are transferred as follows on 3 LVDS lanes.
