From 73f35e0b156c771333d449ca86b99600d094d37f Mon Sep 17 00:00:00 2001
From: Nobuhiro Iwamatsu <nobuhiro.iwamatsu.yj@renesas.com>
Date: Tue, 21 Aug 2012 13:14:46 +0900
Subject: [PATCH] sh: tmu: Changed TMU driver using array of structures
This changed into access using array of structure from access to the register
using the definition of the register by macro.
And removed white space.
