[PATCH v4 4/4] arm64: dts: rockchip: add sdmmc UHS support for roc-rk3328-cc

From: Levin Du In roc-rk3328-cc board, the signal voltage of sdmmc is supplied by the vcc_sdio regulator, which is a mux between 1.8V and 3.3V, controlled by a special output only gpio pin labeled "gpiomut_pmuio_iout", corresponding bit 1 of the syscon GRF_SOC_CON10. This special pin can now be
