[PATCH 7/8] ARM: dts: berlin: convert BG2CD to DT clock nodes
From: sebastian.hesselbarth@gmail.com (Sebastian Hesselbarth)
Date: 2014-05-11 20:25:11
Also in:
linux-devicetree, lkml
Subsystem:
common clk framework, open firmware and flattened device tree bindings, the rest · Maintainers:
Michael Turquette, Stephen Boyd, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds
This converts Berlin BG2CD SoC dtsi to make use of the new DT clock nodes for Berlin SoCs. Also add a binding include to ease core clock references.
