Subject: [PATCH 03/04] sh: use ioread32/iowrite32 and mapped_reg for div4
Date: Thu, 08 Dec 2011 13:59:13 +0000 [thread overview]
Message-ID: <20111208135913.18394.31847.sendpatchset@w520> (raw)
From: Magnus Damm <damm@opensource.se>
Convert the CPG DIV4 helper code to use the new mapped_reg
together with ioread32() and iowrite32().
