From 84a38fd3678b3473c890f7e1b1d7b697afb142a7 Mon Sep 17 00:00:00 2001
From: Andy Green <andy@openmoko.com>
Date: Fri, 25 Jul 2008 23:06:10 +0100
Subject: [PATCH] fix-reduce-wake-reasons-in-pcf50633.patch

Currently we are willing to wake from sleep from
pcf50633 interrupts we don't actually do anything about
even when we wake (somewhat puzzled).

Let's disable some of these wake sources.
