Subject: [PATCH v3 04/10] ARM: dts: Exynos5420: add CPU OPP and regulator
supply property
From: Thomas Abraham <thomas.ab@...sung.com>
For Exynos5420 platforms, add CPU operating points and CPU
regulator supply properties for migrating from Exynos specific
cpufreq driver to using generic cpufreq driver.
Changes by Bartlomiej:
- split Exynos5420 support from the original patch
Changes by Ben Gamari:
- Port to operating-points-v2
