Subject: [PATCH 4/5] arm: imx53: clk: add ARM clock
Date: Fri, 19 Sep 2014 18:16:20 +0200	[thread overview]
Message-ID: <1411143381-10516-5-git-send-email-l.stach@pengutronix.de> (raw)
In-Reply-To: <1411143381-10516-1-git-send-email-l.stach@pengutronix.de>

The ARM clock is a virtual clock feeding the ARM partition of
the SoC. It controls multiple other clocks to ensure the right
sequencing when cpufreq changes the CPU clock rate.
