Subject: spitz: add gpio button support
Message-ID: <20091006074635.GA2775@ucw.cz>
To: linux-arm-kernel@lists.infradead.org
List-Id: linux-arm-kernel.lists.infradead.org


This is call for testing/comments. It adds support for power button,
SWA and SWB.. I'm not sure what AK_INT is, nor what event it should
generate. Unfortunately, this does _not_ fix suspend/resume, and
neither does switch back to old spitz-keyboard help.
