Dual-link LVDS displays receive odd pixels and even pixels separately from dual LVDS links. One link receives odd pixels and the other receives even pixels. Some of those displays may also use only one LVDS link to receive all pixels, being odd and even agnostic. Document common properties for those displays by extending LVDS display common properties defined in lvds.yaml.

description: |
|
|
This binding file is a collection of the LVDS panels that
|
|
has dual LVDS ports and requires only a single power-supply.
|
|
The first port receives odd pixels, and the second port receives even pixels.
|
|
There are optionally a backlight and an enable GPIO.
|
|
The panel may use an OF graph binding for the association to the display,
|
|
or it may be a direct child node of the display.
|
|
|
|
If the panel is more advanced a dedicated binding file is required.
