Subject: [PATCH] drivers: sh: resume enabled clocks fix
Date: Mon, 13 Jun 2011 04:42:15 +0000 [thread overview]
Message-ID: <20110613044215.13907.39264.sendpatchset@t400s> (raw)
From: Magnus Damm <damm@opensource.se>
Extend the SH / SH-Mobile ARM clock framework to only
resume clocks that has been enabled.
Without this fix divide-by-zero is triggering on sh7372
FSIDIV during system wide resume of Suspend-to-RAM.
