[PATCH v1 3/3] arm64: dts: rockchip: add cpu regulator for rk3328 evaluation board

From: <hidden>
Date: 2017-08-23 08:36:32

From: Liang Chen <redacted>

RK3328 Evaluation Board use rk805 pmic, and one of the DCDCs in
rk805 is for cpu regulator, assign the cpu regulator, so the
cpufreq can work fine.
