[PATCH 1/2] ARM: dts: uniphier: add CPU clocks and OPP table for Pro5 SoC

From: Masahiro Yamada <hidden>
Date: 2016-10-26 16:40:47
Also in: linux-devicetree, linux-pm, lkml
Subsystem: the rest · Maintainer: Linus Torvalds

Add a CPU clock to every CPU node and a CPU OPP table to use the
generic cpufreq driver.
