[PATCH v5 3/7] ARM: dts: Exynos542x/5800: add CPU OPP properties
Bartlomiej Zolnierkiewicz

Thu Dec 10 08:58:45 PST 2015
From: Thomas Abraham <thomas.ab at samsung.com>
For Exynos542x/5800 platforms, add CPU operating points
for migrating from Exynos specific cpufreq driver to using
generic cpufreq driver.
Changes by Bartlomiej:
- split Exynos5420 support from the original patch
- merged Exynos5422 fixes from Ben
Changes by Ben Gamari:
- Port to operating-points-v2
