+Subject: [REVIEW PATCH] Added OMAP3EVM support on Tomis FBDEV/DSS Patches
+Date: Fri, 14 Nov 2008 12:02:32 +0530
+
+From: Vaibhav Hiremath <hvaibhav@ti.com>
+
+Tested LCD, TV, DVI (480P) out on OMAP3EVM board.
+
+Please make sure that you change the option
+CONFIG_FB_OMAP_CONSISTENT_DMA_SIZE=7 and apply the
+Mans Rullgard clock patches to support set_rate and round_rate API.
