[PATCH 7/8] arm64: dts: rockchip: Add SDMMC/SDIO controllers for RK3528

Yao Zi
2025-03-01T10:57:58Z

RK3528 features two SDIO controllers and one SD/MMC controller, describe
them in devicetree. Since their sample and drive clocks are located in
the VO and VPU GRFs, corresponding syscons are added to make these
clocks available.
