[PATCH 0/8] Support SD/SDIO controllers on RK3528

[Yao Zi]

RK3528 features two SDIO controllers and one SD/MMC controller. This
series adds essential support for their tuning clocks, document the
controller in dt-bindings and bring the SD/MMC one up on Radxa E20C
board with pinctrl set up by the previous bootloader. Both HS and SDR104
mode are verified.
