From c87b390673167a65a52c0e8da22e2842862227f1 Mon Sep 17 00:00:00 2001 From: Tomi Valkeinen Date: Mon, 3 Aug 2009 15:06:36 +0300 Subject: [PATCH 02/18] OMAP: OMAPFB: split omapfb.h Split arch/arm/plat-omap/include/mach/omapfb.h into two files: include/linux/omapfb.h - ioctls etc for userspace and some kernel stuff for board files drivers/video/omap/omapfb.h - for omapfb internal use This cleans up omapfb.h and also makes it easier for the upcoming new DSS driver to co-exist with the old driver.
