13  Common properties for LVDS displays with dual LVDS links. Extend LVDS display
14  common properties defined in lvds.yaml.
15
16  Dual-link LVDS displays receive odd pixels and even pixels separately from
17  the dual LVDS links. One link receives odd pixels and the other receives
18  even pixels. Some of those displays may also use only one LVDS link to
19  receive all pixels, being odd and even agnostic.
