+Subject: [PATCH] DSS2: VRAM: improve omap_vram_add_region()
+
+Combine postponed and non-posponed versions of omap_vram_add_region.
+Make the func non-static, so it can be called from board files.

+Subject: [PATCH] DSS2: Added support for querying color keying.
+
+V4L2 Framework has a ioctl for getting/setting color keying.
+So added the function manager pointers for doing same.
+
+Modifed the color keying sysfs entries to use manager
+function pointer. Earlier they were calling direcly
+dispc function to set/enable color keying.
+
+Some of color-keying function pointers in the overlay_manager
+structure re-named to be more specific.

+Subject: [PATCH] DSS2: Provided proper exclusion for destination color keying and alpha blending.
+
+OMAP does not support destination color key and alpha blending
+simultaneously.  So this patch does not allow the user
+so set both at a time.
