2024-02-28mmc: Merge branch fixes into nextUlf Hansson
Merge the mmc fixes for v6.8-rc[n] into the next branch, to allow them to get tested together with the new mmc changes that are targeted for v6.9. Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
2024-02-28mmc: sdhci-xenon: add timeout for PHY init completeElad Nachman
AC5X spec says PHY init complete bit must be polled until zero. We see cases in which timeout can take longer than the standard calculation on AC5X, which is expected following the spec comment above. According to the spec, we must wait as long as it takes for that bit to toggle on AC5X. Cap that with 100 delay loops so we won't get stuck forever.

2024-02-28mmc: sdhci-xenon: fix PHY init clock stabilityElad Nachman
Each time SD/mmc phy is initialized, at times, in some of the attempts, phy fails to completes its initialization which results into timeout error. Per the HW spec, it is a pre-requisite to ensure a stable SD clock before a phy initialization is attempted.

2024-02-28mmc: sh_mmcif: Advance sg_miter before reading blocksLinus Walleij
The introduction of sg_miter was a bit sloppy as it didn't exactly mimic the semantics of the old code on multiblock reads and writes: these like you to: - Advance to the first sglist entry *before* starting to read any blocks from the card. - Advance and check availability of the next entry *right after* processing one block. Not checking if we have more sglist entries right after reading a block will lead to this not being checked until we return to the callback to read out more blocks, i.e. until the next interrupt arrives. Since the last block is the last one (no more data will arrive) there will not be a next interrupt, and we will be waiting forever resulting in a timeout for command 18 when reading multiple blocks. The same bug was fixed also in the writing of multiple blocks.

All the sglist iterations happen in the *threaded* interrupt handler and that context is not atomic, so don't request an atomic sglist miter.

2024-02-28mmc: sdhci-esdhc-mcf: Flag the sg_miter as atomicLinus Walleij
The sg_miter used to loop over the returned sglist from a transfer in the esdhc subdriver for SDHCI can be called from atomic context so the miter needs to be atomic. sdhci_request_done() is always called from process context, either as a work or as part of the threaded interrupt handler, but the one case when we are actually calling .request_done() from an atomic context is in sdhci_irq(). Fix this by flagging the miter atomic so we always use kmap_atomic().

Commit 32f18e596141 ("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.

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.

2024-02-13mmc: moxart-mmc: Fix accounting in DMA transferLinus Walleij
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.

2024-02-13mmc: core Drop BLK_BOUNCE_HIGHLinus Walleij
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.

git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394 Pull firewire fix from Takashi Sakamoto: "A change to accelerate the device detection step in some cases. 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
