[PATCH v4 0/4] StarFive's SDIO/eMMC driver support

[William Qiu]

Hi,

This patchset adds initial rudimentary support for the StarFive
designware mobile storage host controller driver. And this driver will
be used in StarFive's VisionFive 2 board. The main purpose of adding
this driver is to accommodate the ultra-high speed mode of eMMC.

The last patch should be applied after the patchset [1]:
