+From 17254fca49c4f3a8897a6afb10af3416a691cb8a Mon Sep 17 00:00:00 2001
+From: Tomi Valkeinen <tomi.valkeinen@nokia.com>
+Date: Fri, 7 Aug 2009 13:42:34 +0300
+Subject: [PATCH 07/18] OMAP: DSS2: Display Subsystem Driver core
+
+The core files of DSS2. DSS2 commits are split a bit artificially to
+make the individual commits smaller, and DSS2 doesn't compile properly
+without the rest of the core commits. This shouldn't be a problem, as no
+configuration uses DSS2 yet.
