Turning the cache off implies flushing cache which doesn't define maximum timeout unlike cache-on. This patch will apply the generic CMD6 timeout only for cache-on. Additionally the kernel message is added for checking failure case of cache-on. Signed-off-by:

With the inclusion of following patch (59b5bc3929b37): "mmc: sdhci: remove "state" argument from sdhci_suspend_host" we get a compilation error for sdhci-spear: drivers/mmc/host/sdhci-spear.c:283:2: error: too many arguments to function ‘sdhci_suspend_host’ This patch fixes this error.

If there are errors happened in sdhci_suspend_host, handle it so that when the function returns with an error, the host's behaviour is the same before this function call, e.g. card detection is enabled and tuning timer is active, etc. Signed-off-by:

UHS_REG should be cleared for non-DDR mode. But currently there is no way to clear DDR mode, if it is already set once. This patch adds clearing DDR mode for non-DDR mode. Signed-off-by:

This patch fixes a failure to recognize SD cards reported on a Dell Vostro with O2 Micro SD card reader. Patch 49c468fc ("mmc: sd: add support for uhs bus speed mode selection") caused the problem, by setting the SDHCI_CTRL_HISPD flag even for legacy timings. Signed-off-by:

Host may now use MMC_CAP2_NO_SLEEP_CMD to disable the use of eMMC sleep/awake command. This option can be used when your platform has a buggy kernel crash dump software, which is supposed to store the dump on the eMMC, but is not able to wake up the eMMC from sleep state. In particular, failures have been seen with u-boot; even if it is fixed there, platforms will be slow to update their bootloader binaries. Signed-off-by:

As the card-detect irq handler just schedules work to be done by a thread, we can use request_threaded_irq to do much of the work for us. This means that interrupts which arrive by handle_nested_irq actually work. Reviewed-by:

To allow the set_clock host op to disable the SDCLK source when not needed, always call the host op when the requested clock speed is zero. Do this even if host->clock already equals zero, because the SDHCI driver may set that value (without calling the host op) to force an update at the next (non-zero-speed) call. Signed-off-by:

Even if a driver provides separate card detection, an interrupt is still needed to abort mmc requests that are in progress. SDHCI_QUIRK2_OWN_CARD_DETECTION prevents that, so remove it. Signed-off-by:

Add a means of getting platform data for the SDHCI PCI devices. The data is stored against the slot not the device in order to support multi-slot devices. The data allows platform-specific setup (such as getting GPIO numbers from firmware or setting up wl12xx for SDIO) to be done in platform support files instead of the sdhci-pci driver. Signed-off-by:

If an interrupt is coming with both error and data completion status bits set, it has to be handled as an error interrupt, for which error interrupts have to be processed first. The current version of the driver on the contrary doesn't recognise such interrupts as an error event, which leads to data corruption and breaks the error recovery. Signed-off-by:

This patch adds a primitive helper to support card hotplug detection on platforms, where a GPIO, capable of producing interrupts, is used for detection of card-insertion and -removal events. Signed-off-by:

Guennadi Liakhovetski authored
SD/MMC controllers provide different card insertion and removal detection methods. On some of them the controller itself issues an interrupt, on others polling is used, on yet others auxiliary means are used for this purpose, e.g., a GPIO IRQ. Further, on some systems one of those methods can be chosen at driver probing time and configured in software. E.g., on some systems the SD/MMC controller card hot-plug detection pin can be configured either as a respective controller functions, or an IRQ-capable GPIO. To support such flexible configurations a card hot-plug context is added by this patch. Signed-off-by:

This patch fixes the wrong comparison before setting the interface voltage in DDR mode. The assignment to the variable ddr before comaprison is either ddr = MMC_1_2V_DDR_MODE; or ddr == MMC_1_8V_DDR_MODE. But the comparison is done with the extended csd value if ddr == EXT_CSD_CARD_TYPE_DDR_1_2V. Signed-off-by:
