NAME
dwmshc - Synopsys DesignWare Mobile Storage Host Controller
SYNOPSIS
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 RK3566
and RK3568 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.
