During test campaign, and especially after several unbind/bind sequences, it has been seen that the SD-card on SDMMC1 thread could freeze. The freeze always appear on a CMD23 following a CMD19. Checking SDMMC internal registers shows that the tuning command (CMD19) has failed. The freeze is then due to the delay block involved in the tuning sequence. To correct this, clear the delay block register DLYB_CR register after the tuning commands. Signed-off-by:

The vendor driver implements special handling for multi-block SD_IO_RW_EXTENDED (and SD_IO_RW_DIRECT) commands which have data attached to them. It sets the MANUAL_STOP bit in the MESON_SDHC_MISC register for these commands. In all other cases this bit is cleared. Here we omit SD_IO_RW_DIRECT since that command never has any data attached to it. This fixes SDIO wifi using the brcmfmac driver which reported the following error without this change on a Netxeon S82 board using a Meson8 (S802) SoC: brcmf_fw_alloc_request: using brcm/brcmfmac43362-sdio for chip BCM43362/1 brcmf_sdiod_ramrw: membytes transfer failed brcmf_sdio_download_code_file: error -110 on writing 219557 membytes at 0x00000000 brcmf_sdio_download_firmware: dongle image file download failed And with this change: brcmf_fw_alloc_request: using brcm/brcmfmac43362-sdio for chip BCM43362/1 brcmf_c_process_clm_blob: no clm_blob available (err=-2), device may have limited channels available brcmf_c_preinit_dcmds: Firmware: BCM43362/1 wl0: Apr 22 2013 14:50:00 version 5.90.195.89.6 FWID 01-b30a427d Fixes: e4bf1b09 ("mmc: host: meson-mx-sdhc: new driver for the Amlogic Meson SDHC host") Signed-off-by:Martin Blumenstingl <martin.blumenstingl@googlemail.com> Cc: stable@vger.kernel.org Link: https://lore.kernel.org/r/20211219153442.463863-2-martin.blumenstingl@googlemail.com Signed-off-by:

It's seems prone to problems by allowing card detect and its corresponding mmc_rescan() work to run, during platform shutdown. For example, we may end up turning off the power while initializing a card, which potentially could damage it. To avoid this scenario, let's add ->shutdown_pre() callback for the mmc host class device and then turn of the card detect from there. Reported-by:

nr_free_buffer_pages could be exposed through mm.h instead of swap.h. The advantage of this change is that it can reduce the obsolete includes. For example, net/ipv4/tcp.c wouldn't need swap.h any more since it has already included mm.h. Similarly, after checking all the other files, it comes that tcp.c, udp.c meter.c ,... follow the same rule, so these files can have swap.h removed too. Moreover, after preprocessing all the files that use nr_free_buffer_pages, it turns out that those files have already included mm.h.Thus, we can move nr_free_buffer_pages from swap.h to mm.h safely. This change will not affect the compilation of other files. Link: https://lkml.kernel.org/r/20210912133640.1624-1-liumh1@shanghaitech.edu.cn Signed-off-by:

For dw_mmc, the ->init_card() callback is being used to turn on/off automatic internal clock gating for powersave, which is needed to properly support SDIO irqs on DAT1. However, using the ->init_card() comes with a drawback in this case, as it means that the powersave feature becomes disabled, no matter whether the SDIO irqs becomes turned on or not. To improve the behaviour, let's change into using the ->enable_sdio_irq() callback instead. This works fine, because dw_mmc uses sdio_signal_irq() to signal the irqs, thus the ->enable_sdio_irq() is never executed from within atomic context. Signed-off-by:

blk_keyslot_manager is misnamed because it doesn't necessarily manage keyslots. It actually does several different things: - Contains the crypto capabilities of the device. - Provides functions to control the inline encryption hardware. Originally these were just for programming/evicting keyslots; however, new functionality (hardware-wrapped keys) will require new functions here which are unrelated to keyslots. Moreover, device-mapper devices already (ab)use "keyslot_evict" to pass key eviction requests to their underlying devices even though device-mapper devices don't have any keyslots themselves (so it really should be "evict_key", not "keyslot_evict"). - Sometimes (but not always!) it manages keyslots. Originally it always did, but device-mapper devices don't have keyslots themselves, so they use a "passthrough keyslot manager" which doesn't actually manage keyslots. This hack works, but the terminology is unnatural. Also, some hardware doesn't have keyslots and thus also uses a "passthrough keyslot manager" (support for such hardware is yet to be upstreamed, but it will happen eventually). Let's stop having keyslot managers which don't actually manage keyslots. Instead, rename blk_keyslot_manager to blk_crypto_profile. This is a fairly big change, since for consistency it also has to update keyslot manager-related function names, variable names, and comments -- not just the actual struct name. However it's still a fairly straightforward change, as it doesn't change any actual functionality.

The last user of this struct gone couple of releases ago. Remove the dead code for good and encourage people to use MMC core functionality for that. The removal is dependent on the previous removal of the struct sdhci_pci_data. Signed-off-by:

The last user of this struct gone a couple of releases ago. Besides that there were not so many users of this API for more than 10 years: 1/ The one is Intel Merrifield, that had been added 2016-08-31 by the commit 3976b038 ("x86/platform/intel-mid: Enable SD card detection on Merrifield") and removed 2021-02-11 by the commit 4590d98f ("sfi: Remove framework for deprecated firmware"). 2/ The other is Intel Sunrisepoint related, that had been added 2015-02-06 by the commit e1bfad6d ("mmc: sdhci-pci: Add support for drive strength selection for SPT") and removed 2017-03-20 by the commit 51ced59c ("mmc: sdhci-pci: Use ACPI DSM to get driver strength for some Intel devices"). Effectively this is a revert of the commit 52c506f0 ("mmc: sdhci-pci: add platform data"). Signed-off-by:

The analogue of the sdhci_get_cd_nogpio() is used in the sdhci-pci-core and sdhci-acpi modules. Deduplicate it by moving to sdhci and exporting. Signed-off-by:

There are several error return paths that dereference the null pointer host because the pointer has not yet been set to a valid value. Fix this by adding a new out_mmc label and exiting via this label to avoid the host clean up and hence the null pointer dereference.

Intel Merrifield platform had been converted to use ACPI enumeration. However, the driver missed an update to retrieve card detect GPIO. Fix it here. Unfortunately we can't rely on CD GPIO state because there are two different PCB designs in the wild that are using the opposite card detection sense and there is no way to distinguish those platforms, that's why ignore CD GPIO completely and use it only as an event.

The issue happens in several error handling paths on two refcounted object related to the object "host" (dma_chan_rx, dma_chan_tx). In these paths, the function forgets to decrement one or both objects' reference count increased earlier by dma_request_chan(), causing reference count leaks. Fix it by balancing the refcounts of both objects in some error handling paths. In correspondence with the changes in moxart_probe(), IS_ERR() is replaced with IS_ERR_OR_NULL() in moxart_remove() as well. Signed-off-by:
