Minimal VisionFive2 SDIO driver for storage

Hey, I was wondering what the u-boot driver is for the SD storage support ?
I wasn’t able to find an exact one. I am trying to write my own driver for my bare metal Operating System, so a minimalist example would be great to look at.

Thanks

sdio controller is dwmmc ip
