On devices where the backend is chosen as DRM, as in the case of dra7xx,
we need some additional patches that are specific to the omapdrm
which are needed for basic functionality. This includes some bug fixes
too.

This will fully enable
* multiple display support
* Handle screensavers more efficiently
* Be compatible with libgbm, TI adaptation of libgbm

+Subject: [PATCH] weston: Enabling DRM backend with multiple displays
+
+There are three main issues that this patch tries to address
+
+ 1. Black screen when running weston
+ 2. Support for multiple displays
+ 3. Handling missing VBlanks
+
+There is an issue with missing VBlanks for LCD and
+HDMI connectors which leads to display not getting refreshed.
+This patch can be considered as a workaround.
