4 LVDS is a physical layer specification defined in ANSI/TIA/EIA-644-A. Multiple
5 incompatible data link layers have been used over time to transmit image data
6 to LVDS panels. This bindings supports display panels compatible with the
7 following specifications.
9 [JEIDA] "Digital Interface Standards for Monitor", JEIDA-59-1999, February
10 1999 (Version 1.0), Japan Electronic Industry Development Association (JEIDA)
11 [LDI] "Open LVDS Display Interface", May 1999 (Version 0.95), National
13 [VESA] "VESA Notebook Panel Standard", October 2007 (Version 1.0), Video
14 Electronics Standards Association (VESA)
16 Device compatible with those specifications have been marketed under the
17 FPD-Link and FlatLink brands.
22 - compatible: Shall contain "panel-lvds" in addition to a mandatory
23 panel-specific compatible string defined in individual panel bindings. The
24 "panel-lvds" value shall never be used on its own.
25 - width-mm: See panel-common.txt.
26 - height-mm: See panel-common.txt.
27 - data-mapping: The color signals mapping order, "jeida-18", "jeida-24"
32 - label: See panel-common.txt.
33 - gpios: See panel-common.txt.
34 - backlight: See panel-common.txt.
35 - power-supply: See panel-common.txt.
36 - data-mirror: If set, reverse the bit order described in the data mappings
37 below on all data lanes, transmitting bits for slots 6 to 0 instead of
42 - panel-timing: See panel-common.txt.
43 - ports: See panel-common.txt. These bindings require a single port subnode
44 corresponding to the panel LVDS input.
47 LVDS data mappings are defined as follows.
49 - "jeida-18" - 18-bit data mapping compatible with the [JEIDA], [LDI] and
50 [VESA] specifications. Data are transferred as follows on 3 LVDS lanes.
