[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.

Yao Zi (8):
  dt-bindings: soc: rockchip: Add RK3528 VO GRF syscon
  dt-bindings: soc: rockchip: Add RK3528 VPU GRF syscon
  dt-bindings: mmc: rockchip-dw-mshc: Add compatible string for RK3528
  dt-bindings: clock: Add GRF clock definition for RK3528
  clk: rockchip: Support MMC clocks in GRF region
  clk: rockchip: rk3528: Add SD/SDIO tuning clocks in GRF region
  arm64: dts: rockchip: Add SDMMC/SDIO controllers for RK3528
  arm64: dts: rockchip: Enable SD-card interface on Radxa E20C
