DESCRIPTION

The dwmmc driver provides support for various MMC/SD/SDIO controllers based on the Synopsys DesignWare SD/eMMC core. These controllers are typically found on SoCs, such as the Rockchip RK3288/RK3399 and Samsung Exynos ARM SoCs.

The sdmmc(4) subsystem performs SD/MMC transactions to communicate with whatever MMC/SD/SDIO devices are inserted into the card slot or directly connected to the controller.
