Subject: [PATCH v6 07/11] ARM: mmp: move timer registers into driver
Date: Fri, 26 Jul 2013 18:05:29 +0800	[thread overview]
Message-ID: <1374833133-21119-8-git-send-email-haojian.zhuang@gmail.com> (raw)
In-Reply-To: <1374833133-21119-1-git-send-email-haojian.zhuang@gmail.com>

Move the definition of timer registers into timer-mmp driver.
And map timer registers in driver.
