It's normal to have this situation when the SD card slot is empty, therefore we should not warn the user about it.

2023-01-27mmc: atmel-mci: fix race between stop command and start of next commandTobias Schramm
This commit fixes a race between completion of stop command and start of a new command. Previously the command ready interrupt was enabled before stop command was written to the command register. This caused the command ready interrupt to fire immediately since the CMDRDY flag is asserted constantly while there is no command in progress. Consequently the command state machine will immediately advance to the next state when the tasklet function is executed again, no matter actual completion state of the stop command. Thus a new command can then be dispatched immediately, interrupting and corrupting the stop command on the CMD line. Fix that by dropping the command ready interrupt enable before calling atmci_send_stop_cmd. atmci_send_stop_cmd does already enable the command ready interrupt, no further writes to ATMCI_IER are necessary.

2023-01-23mmc: sdhci-iproc: Replace SDHCI_QUIRK_MISSING_CAPSAdrian Hunter
SDHCI_QUIRK_MISSING_CAPS is not needed because __sdhci_read_caps() can be called instead. In preparation to get rid of SDHCI_QUIRK_MISSING_CAPS, replace SDHCI_QUIRK_MISSING_CAPS with __sdhci_read_caps(). __sdhci_read_caps() is also called from sdhci_setup_host() via sdhci_read_caps(), however only the first call to __sdhci_read_caps() does anything because after that host->read_caps has been set to true. Note, __sdhci_read_caps() does more than just set host->caps, such as do a reset, so calling __sdhci_read_caps() earlier could have unforeseen side-effects. However the code flow has been reviewed with that in mind.

2023-01-23mmc: sdhci-esdhc-imx: only enable DAT[0] and CMD line auto tuning for SDIO ↵Haibo Chen
device USDHC IP has one limitation: the tuning circuit can't handle the async sdio device interrupt correctly. When sdio device use 4 data lines, async sdio interrupt will use the shared DAT[1], if enable auto tuning circuit to check these 4 data lines, include the DAT[1], this circuit will detect this interrupt, take this as data on DAT[1], and adjust the delay cell wrongly, finally will cause the DATA/CMD CRC error. So for SDIO device, only enable DAT[0] and CMD line for auto tuning. To distinguish the card type during card init, involve init_card().

The SDHI/eMMC IPs found with the RZ/V2M (a.k.a. r9a09g011), are very similar to the ones found in R-Car Gen3, but they are not exactly the same, and as a result need an SoC specific compatible string for fine tuning driver support.
