[PATCH v1 0/3] Enable some devices for rk3328 evaluation board

From: Liang Chen <redacted>

1. enalbe sdio/sdmmc/emmc.
2. enable cpufreq.

change in v2:

1. remove useless properties in mmc nodes.

Liang Chen (3):
  arm64: dts: rockchip: add mmc nodes for rk3328 evaluation board
  cpufreq: rockchip: add support for rk3328 soc
  arm64: dts: rockchip: add cpu regulator for rk3328 evaluation board

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.

applied ... but I cannot say if it will still be eligible for 4.14
(late in the cycle). If necessary I'll move it forward a release.

Add compatible rockchip,rk3328 to the machines table to
launch cpufreq-dt driver for rk3328 soc.

Rockchip's rk3328 evaluation board has 3 mmc controllers for
sdio/sdmmc/emmc, let's enable them.
