Enabling this feature will allow the controller to stop the bus clock when the bus is idle. The feature is not part of the standard and is unique to newer Arasan cores and is enabled with a bit in a vendor specific register. This feature will only be enabled for non-removable devices because they don't switch the voltage and clock gating breaks SD Card volatge switching. Signed-off-by:

Newer variants of the MMC controller support a 34-bit physical address space by using word addresses instead of byte addresses. However, the code truncates the DMA descriptor address to 32 bits before applying the shift. This breaks DMA for descriptors allocated above the 32-bit limit.

To make the entropy pool a bit better we can toss in the CID for eMMC and SD cards into it, usually the serial number portion is at least unique. This does not count as improvement of the entropy but in practice it makes it a bit more random to mix in these numbers. Cc: Theodore Ts'o <tytso@mit.edu> Acked-by:

Occasionally, user-land applications initiate longer timeout values for certain commands through ioctl() system call. But so far we are still using a fixed timeout of 10 seconds in mmc_poll_for_busy() on the ioctl() path, even if a custom timeout is specified in the userspace application. This patch allows custom timeout values to override this default timeout values on the ioctl path. Cc: stable <stable@vger.kernel.org> Signed-off-by:

The ARASAN MMC controller on Keystone 3 class of devices need the SDCD line to be connected for proper functioning. Similar to the issue pointed out in sdhci-of-arasan.c driver, commit 3794c542 ("mmc: sdhci-of-arasan: Set controller to test mode when no CD bit"). In cases where this can't be connected, add a quirk to force the controller into test mode and set the TESTCD bit. Use the flag "ti,fails-without-test-cd", to implement this above quirk when required. Signed-off-by:

The SDHC controller in the imx8mn and imx8mp have the same controller as the imx8mm which is slightly different than that of the imx7d. Using the fallback of the imx8mm enables the controllers to support HS400-ES which is not available on the imx7d. After discussion with NXP, it turns out that the imx8qm should fall back to the imx8qxp, because those have some additional flags not present in the imx8mm. Mark the current state of the fallbacks as deprecated, and add the proper fallbacks so in the future, the deprecated combination can be removed and prevent any future devices from using the wrong fallback.

To make it unambiguous that the hw_reset callback is for cards and not for controllers, we add 'card' to the callback name and convert all users in one go. We keep the argument as mmc_host, though, because the callback is used very early when mmc_card is not yet populated. Signed-off-by:

Despite mmc_ioc_multi_cmd::num_of_cmds is a 64-bit field, its maximum value is limited to MMC_IOC_MAX_CMDS (only 255); using a 64-bit local variable to hold a copy of that field leads to gcc generating ineffective loop code: despite the source code using an *int* variable for the loop counters, the 32-bit object code uses 64-bit unsigned counters. Also, gcc has to drop the most significant word of that 64-bit variable when calling kcalloc() and assigning to mmc_queue_req::ioc_count anyway. Using the *unsigned int* variable instead results in a better code. Found by Linux Verification Center (linuxtesting.org) with the SVACE static analysis tool. Signed-off-by:

Convert the marvell,xenon-sdhci binding to JSON schema. Currently the in-tree dts files don't validate because they use sdhci@ instead of mmc@ as required by the generic mmc-controller schema. The compatible "marvell,sdhci-xenon" was not documented in the old binding but it accompanies the of "marvell,armada-3700-sdhci" in the armada-37xx SoC dtsi so this combination is added to the new binding document.

In SDIO mode, the sg list for requests can be unaligned with what the STM32 SDMMC internal DMA can support. In that case, instead of failing, use a temporary bounce buffer to copy from/to the sg list. This buffer is limited to 1MB. But for that we need to also limit max_req_size to 1MB. It has not shown any throughput penalties for SD-cards or eMMC. Signed-off-by:
