SDMMC Host Driver

SD Host side related components are:

sdmmc
esp_driver_sdmmc (current component)
esp_driver_sdspi

For relationship and dependency among these components, see SD Host Side Related Component Architecture.

esp_driver_sdmmc components holds SDMMC Host driver for ESP SDMMC peripheral, this driver provides APIs to help you:

do SD transactions (under SD mode) via ESP SDMMC peripheral.
tune ESP SDMMC hardware configurations, such as clock frequency, bus width, etc.
...

You can

use this driver to implement sdmmc protocol interfaces
directly use esp_driver_sdmmc APIs

to communicate with SD slave devices under SD mode.
