Subject: [PATCH 02/12] arm/mxs: convert platform code to clk_prepare/clk_unprepare
Date: Tue, 20 Dec 2011 20:00:33 +0800	[thread overview]
Message-ID: <1324382443-4439-3-git-send-email-shawn.guo@linaro.org> (raw)
In-Reply-To: <1324382443-4439-1-git-send-email-shawn.guo@linaro.org>

The patch converts mxs platform code to clk_prepare/clk_unprepare
by using helper functions clk_prepare_enable/clk_disable_unprepare.
