This is a driver for the eMMC Host Controller found in devices based on the Qualcomm SDM630/636/660 SoC. The driver works in conjunction with sdport.sys, which implements SD/SDIO/eMMC protocol and WDM interfaces, to provide the host register interface.

This driver provides a functional miniport implementation for the Qualcomm SDM630/636/660 eMMC Host Controller.

However, it does not have support for many more recent features such as:

• UHS-I speed modes.

• HS400

The driver contains dirty fixes, such as disabled PIO and hardcoded voltage.

This driver is based on Microsoft's SDHC sample and utilizes several request handling fixes from dwcsdhc.
