This patch series enables VPBE display driver on DM355.
This patch series is dependent on this patches posted
http://www.spinics.net/lists/arm-kernel/msg188234.html
Changes for v3:
1: Replaced obsolete preset API by timings API.
Changes for v2:
1: Removed VPSS clock alias for master and slave which was
sent for VPSS driver. since this patch was dependent on
patch[1]. I will revist this patch once MC(captrure driver)
goes into mainline.
