Subject: [PATCH 1/2] net: flexcan: clock-frequency is optional for device tree probe
Date: Tue, 26 Jun 2012 16:49:22 +0800 [thread overview]
Message-ID: <1340700563-8386-2-git-send-email-shawn.guo@linaro.org> (raw)
In-Reply-To: <1340700563-8386-1-git-send-email-shawn.guo@linaro.org>
The property clock-frequency is optional for device tree probe. When
it's absent, the flexcan driver will try to get the frequency from clk
system by calling clk_get_rate.
