Dual-link LVDS interfaces have 2 links, with even pixels traveling on one link, and odd pixels on the other. These panels are also generic in nature, with no documented constraints, much like their single-link counterparts, "panel-lvds". Add a new compatible, "panel-dual-lvds", and a dt-binding document for these panels.
