The clocking of the designware MMC controller in the upstream (i.e. Linux) RK3399 has changed/does not match what the current DTS in U-Boot uses: the first clock entry now is HCLK_SDMMC instead of SCLK_SDMMC.
With the simple clock driver used for the RK3399, this needs a change in the selector understood by the various case statements in the driver to ensure that the driver still loads successfully.
