Since commit aed65af1 ("drivers: make device_type const"), the driver core can properly handle constant struct device_type. Move the sdio_type, sd_type and mmc_type variables to be constant structures as well, placing it into read-only memory which can not be modified at runtime.

Commit 32f18e59 ("mmc: improve API to make clear hw_reset callback is for cards") made it clear that the hw_reset callback is intended for resetting the card. Remove the .card_hw_reset callback from the meson-mx-sdhc-mmc driver because it's purpose is to reset the SDHC controller (FIFOs, PHY, DMA interface, ...). While here also rename and change the argument of meson_mx_sdhc_hw_reset so it cannot be called by accident as a replacement for card_hw_reset in the future. Signed-off-by:

Initializing an eMMC that's connected via a 1-bit bus is current failing, if the HW (DT) informs that 4-bit bus is supported. In fact this is a regression, as we were earlier capable of falling back to 1-bit mode, when switching to 4/8-bit bus failed. Therefore, let's restore the behaviour.

Use the scatterlist memory iterator instead of just dereferencing virtual memory using sg_virt(). This make highmem references work properly. This driver also has a bug in the PIO sglist handling that is fixed as part of the patch: it does not travers the list of scatterbuffers: it will just process the first item in the list. This is fixed by augmenting the logic such that we do not process more than one sgitem per IRQ instead of counting down potentially the whole length of the request. We can suspect that the PIO path is quite untested. Suggested-by:

The whole scatterlist chain is submitted to the DMA engine, but the code is written to just account for the length of the first sg entry. When the DMA transfer is finished, all the data in the request has been transferred, account for this instead. This only works because the moxart_request() function isn't checking that all data was transferred and will unconditionally issue mmc_request_done() after returning successfully from moxart_transfer_dma(). Keep the assignment of accounted bytes in .bytes_xfered but move it after the completion where we know it has actually happened. Signed-off-by:

The MMC core sets BLK_BOUNCE_HIGH for devices where dma_mask is unassigned. For the majority of MMC hosts this path is never taken: the OF core will unconditionally assign a 32-bit mask to any OF device, and most MMC hosts are probed from device tree, see drivers/of/platform.c: of_platform_device_create_pdata() dev->dev.coherent_dma_mask = DMA_BIT_MASK(32); if (!dev->dev.dma_mask) dev->dev.dma_mask = &dev->dev.coherent_dma_mask; of_amba_device_create() dev->dev.coherent_dma_mask = DMA_BIT_MASK(32); dev->dev.dma_mask = &dev->dev.coherent_dma_mask; MMC devices that are probed from ACPI or PCI will likewise have a proper dma_mask assigned. The only remaining devices that could have a blank dma_mask are platform devices instantiated from board files. These are mostly used on systems without CONFIG_HIGHMEM enabled which means the block layer will not bounce, and in the few cases where it is enabled it is not used anyway: for example some OMAP2 systems such as Nokia n800/n810 will create a platform_device and not assign a dma_mask, however they do not have any highmem, so no bouncing will happen anyway: the block core checks if max_low_pfn >= max_pfn and this will always be false. Should it turn out there is a platform_device with blank DMA mask actually using CONFIG_HIGHMEM somewhere out there we should set dma_mask for it, not do this trickery.

In the self-identification step after bus-reset, all nodes in the same bus broadcast selfID packet including the value of gap count. The value is related to the cable hops between nodes, and used to calculate the subaction gap and the arbitration reset gap. When each node has the different value of the gap count, the asynchronous communication between them is unreliable, since an asynchronous transaction could be interrupted by another asynchronous transaction before completion. The gap count inconsistency can be resolved by several ways; e.g. the transfer of PHY configuration packet and generation of bus-reset. The current implementation of firewire stack can correctly detect the gap count inconsistency, however the recovery action from the inconsistency tends to be delayed after reading configuration ROM of root node. This results in the long time to probe devices in some combinations of hardware. Here the stack is changed to schedule the action as soon as possible" * tag 'firewire-fixes-6.8-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394: firewire: core: send bus reset promptly on gap count error
