+From c09f1a0642fd58a1b081594ea36dfd1bf71aec52 Mon Sep 17 00:00:00 2001
+From: Hardik Shah <hardik.shah@ti.com>
+Date: Thu, 9 Apr 2009 12:13:07 +0530
+Subject: [PATCH] DSS2: OMAPFB: Added support for the YUV VRFB rotation and mirroring.
+
+DSS2 now requires roatation_type to be specified by driver.
+Added support for that.
+DSS2 OMAPFB: Modified to pass the dss mode to omap_vrfb_setup function.
+
+VRFB size register requires the width to be halved when the
+mode is YUV or UYVY. So VRFB is modifed to pass the mode to omap_vrfb_setup
+function.
+
+Few changes done by Tim Yamin
