From mboxrd@z Thu Jan 1 00:00:00 1970 From: Magnus Damm Date: Fri, 08 May 2009 08:32:18 +0000 Subject: [PATCH] sh: TMU platform data for sh7723 Message-Id: <20090508083218.31071.69934.sendpatchset@rx1.opensource.se> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-sh@vger.kernel.org From: Magnus Damm This patch adds TMU platform data for sh7723. Both clockevent and clocksource support is enabled. While at it, adjust the CMT clocksource rating to prioritize the TMU. Signed-off-by: Magnus Damm --- Tested on ap325.
