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 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.
