2022-12-07mmc: sdhci-tegra: Issue CMD and DAT resets togetherPrathamesh Shete
In case of error condition to avoid system crash Tegra SDMMC controller requires CMD and DAT resets issued together. SDHCI controller FSM goes into bad state due to rapid SD card hot-plug event. Issuing reset on the CMD FSM before DATA FSM results in kernel panic, hence add support to issue CMD and DAT resets together. This is applicable to Tegra186 and later chips.

2022-12-07mmc: mmc-hsq: Use fifo to dispatch mmc_requestMichael Wu
Current next_tag selection will cause a large delay in some requests and destroy the scheduling results of the block scheduling layer. Because the issued mrq tags cannot ensure that each time is sequential, especially when the IO load is heavy. In the fio performance test, we found that 4k random read data was sent to mmc_hsq to start calling request_atomic It takes nearly 200ms to process the request, while mmc_hsq has processed thousands of other requests. So we use fifo here to ensure the first in, first out feature of the request and avoid adding additional delay to the request.

2022-12-07mmc: core: Remove non-data R1B ioctl workaroundChristian Löhle
The workaround of pretending R1B non-data transfers are data transfers in order for the busy timeout to be respected by the host controller driver is removed. It wasn't useful in a long time. Initially the workaround ensured that R1B commands did not time out by setting the data timeout to be the command timeout in commit cb87ea28ed9e ("mmc: core: Add mmc CMD+ACMD passthrough ioctl"). This was moved inside an if-clause with idata->buf_bytes being set in commit 4d6144de8ba2 ("mmc: core: check for zero length ioctl data"). Since the workaround is now inside the idata->buf_bytes clause and intended to fix R1B non-data transfers, that do not have buf_bytes set, we can remove the workaround altogether. This was dead code, since data transfers doesn't use R1B commands.

2022-12-07mmc: renesas_sdhi: better reset from HS400 modeWolfram Sang
Up to now, HS400 adjustment mode was only disabled on soft reset when a calibration table was in use. It is safer, though, to disable it as soon as the instance has an adjustment related quirk set, i.e. bad taps or a calibration table.

2022-12-07mmc: renesas_sdhi: take DMA end interrupts into accountWolfram Sang
So far, we have been relying on access_end interrupts only to mark DMA transfers as done implying that DMA end interrupts have occurred by then anyhow. On some SoCs under some conditions, this turned out to be not enough. So, we enable DMA interrupts as well and make sure that both events, DMA irq and access_end irq, have happened before finishing the DMA transfer.
