[PATCH v2 4/6] arm: imx53: clk: add ARM clock
From: l.stach@pengutronix.de (Lucas Stach)
Date: 2014-09-26 13:41:02

Subsystem:
arm port, common clk framework, nxp i.mx clock drivers, open firmware and flattened device tree bindings, the rest · Maintainers:
Russell King, Michael Turquette, Stephen Boyd, Abel Vesa, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds
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.
