Subject: [PATCH 5/5] ARM: dts: Add initial regulator mode on exynos Peach boards
The regulator core now has support to choose a default initial
operating mode for regulators from DT. Set the initial opmode
for the max77802 PMIC regulators with the same modes that are
used in the downstream ChromeOS kernel, in order to allow the
system to lower power at suspend time.
