From b295c22978b86fc62019d12f4108b68b7e795610 Mon Sep 17 00:00:00 2001 From: Philipp Zabel Date: Tue, 2 Dec 2014 17:49:04 +0100 Subject: [PATCH] Add LVDS RGB media bus formats This patch adds three new RGB media bus formats that describe 18-bit or 24-bit samples transferred over an LVDS bus with three or four differential data pairs, serialized into 7 time slots, using standard SPWG/PSWG/VESA or JEIDA data ordering.
