dwmshc* at fdt?
sdmmc* at dwmshc?
DESCRIPTION
The dwmshc driver provides support for the
Synopsys DesignWare Mobile Storage Host Controller core. This core is used
on the Rockchip RK3528, RK3566/RK3568 and RK3588 SoCs as the eMMC
controller.
The Synopsys DesignWare Mobile Storage Host Controller core implements the SD Host Controller Standard Simplified Specification, but requires non-standard support for high clock rates.
The sdmmc(4) subsystem performs SD/MMC transactions to communicate with the MMC/SD/SDIO devices connected to the controller.
