kgene/for-next?

[PATCH v12 3/6] ARM: dts: Exynos: add CPU OPP and regulator supply property

2014-11-21 Thread Thomas Abraham

For Exynos 4210/5250/5420 based platforms, add CPU operating points and CPU
regulator supply properties for migrating from Exynos specific cpufreq driver
to using generic cpufreq drivers.
