From c40fae9525e6c29c87a4f4361ff0a8d67a36e448 Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Thu, 7 Dec 2006 13:58:10 -0800 Subject: [PATCH] ARM: OMAP: Sync core code with linux-omap This patch syncs omap specific core code with linux-omap. Most of the changes are needed to fix bitrot caused by driver updates in linux-omap tree.
