Aug 01, 2013 · This is suppose to be the generic standard MMC/SD/SDIO driver used by many vendors. What I can't figure out is how to specify in the DTS to use this "Secure Digital Host Controller Interface Support" driver, that was selected from kconfig. I am unable to find a reference entry of an DTS file specifying its use for MMC/SD/SDIO.

Feb 26, 2019 · SD spec v5.1 adds discard support. The flows and commands are similar to mmc, so just set the discard arg in CMD38. A host which supports DISCARD shall check if the DISCARD_SUPPORT (b313) is set in the SD_STATUS register. If the card does not support discard, the host shall not issue DISCARD command, but ERASE command instead.
