[PATCH v3 2/4] ARM: dts: Exynos5250: add CPU OPP and regulator supply property

From: Bartlomiej Zolnierkiewicz
Date: Wed Jul 01 2015 - 09:13:57 EST


From: Thomas Abraham <thomas.ab@xxxxxxxxxxx>

For Exynos5250 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 Exynos5250 support from the original patch
- added CPU regulator supply property for Google Spring board
- put the new cpu nodes in alphabetical order
