Subject: [PATCH 1/2] ARM: imx6q: call of_clk_init() to register fixed rate clocks
Date: Tue, 21 May 2013 10:12:03 +0800	[thread overview]
Message-ID: <1369102324-3084-1-git-send-email-shawn.guo@linaro.org> (raw)

As the fixed rate clocks are defined in device tree, we can just call
of_clk_init() to register them.
