[PATCH v2 5/7] ARM: dts: Exynos4x12: add CPU OPP and regulator supply property

Bartlomiej Zolnierkiewicz b.zolnierkie at samsung.com
Thu Jul 9 08:43:39 PDT 2015


For Exynos4x12 platforms, add CPU operating points (using
opp-v2 bindings) 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.
