Subject: [PATCH 1/2] ARM: imx6q: call of_clk_init() to register fixed rate clocks
Date: Thu, 23 May 2013 10:30:05 -0700	[thread overview]
Message-ID: <20130523173005.6058.9635@quantum> (raw)
In-Reply-To: <1369102324-3084-1-git-send-email-shawn.guo@linaro.org>

Quoting Shawn Guo (2013-05-20 19:12:03)
> As the fixed rate clocks are defined in device tree, we can just call
> of_clk_init() to register them.
