Patch documented only Single link LVDS as it only supported by driver. Single link LVDS with Channel A configuration is common across all 3 variant chips. I have SN65DSI84 with Single link LVDS which is routed in Channel A. Idea is to go with Single link and add double link later and document the same. Jagan.
