[PATCH 4/6] ARM: dts: Exynos4x12: add CPU OPP and regulator supply property

[Bartlomiej Zolnierkiewicz]

For Exynos4x12 platforms, add CPU operating points and CPU
regulator supply properties for migrating from Exynos specific
cpufreq driver to using generic cpufreq driver.

Based on the earlier work by Thomas Abraham.
