The MSM SDHCI driver always set the "actual_clock" field to 0. It had a comment about it not being needed because we weren't using the standard SDHCI divider mechanism and we'd just fallback to "host->clock". However, it's still better to provide the actual clock. Why? 1. It will make timeout calculations slightly better. On one system I have, the eMMC requets 200 MHz (for HS400-ES) but actually gets 192 MHz. These are close, but why not get the more accurate one. 2. If things are seriously off in the clock driver and it's missing rates or picking the wrong rate (maybe it's rounding up instead of down), this will make it much more obvious what's going on. NOTE: we have to be a little careful here because the "actual_clock" field shouldn't include the multiplier that sdhci-msm needs internally. Suggested-by:

As talked about in commit 5e4b7e82 ("clk: qcom: gcc-sdm845: Use floor ops for sdcc clks"), most clocks handled by the Qualcomm clock drivers are rounded _up_ by default instead of down. We should make sure SD/MMC clocks are always rounded down in the clock drivers. Let's add a warning in the Qualcomm SDHCI driver to help catch the problem. This would have saved a bunch of time [1]. NOTE: this doesn't actually fix any problems, it just makes it obvious to devs that there is a problem and that should be an indication to fix the clock driver.

'sdhci_remove_host()' and 'sdhci_pltfm_free()' should be used in place of 'mmc_remove_host()' and 'mmc_free_host()'.

This adds a driver for the Richtek RT8515 dual channel torch/flash white LED driver. This LED driver is found in some mobile phones from Samsung such as the GT-S7710 and GT-I8190. A V4L interface is added. We do not have a proper datasheet for the RT8515 but it turns out that RT9387A has a public datasheet and is essentially the same chip. We designed the driver in accordance with this datasheet. The day someone needs to drive a RT9387A this driver can probably easily be augmented to handle that chip too. Sakari Ailus, Pavel Machek and Andy Shevchenko helped significantly in getting this driver right.

<workqueue> ata_hsm_qc_complete(): spin_lock_irqsave(&host->lock); write_lock(&trig->leddev_list_lock); ata_port_freeze(): ata_do_link_abort(): ata_qc_complete(): ledtrig_disk_activity(): led_trigger_blink_oneshot(): read_lock(&trig->leddev_list_lock); // ^ not in in_interrupt() context, so could get blocked by CPU 2 <interrupt> ata_bmdma_interrupt(): spin_lock_irqsave(&host->lock); Fix by using read_lock_irqsave/irqrestore() in led_trigger_event(), so that no interrupt can happen in between, preventing the deadlock condition. Apply the same change to led_trigger_blink_setup() as well, since the same deadlock scenario can also happen in power_supply_update_bat_leds() -> led_trigger_blink() -> led_trigger_blink_setup() (workqueue context), and potentially prevent other similar usages.

Properties with standard unit suffixes already have a type and don't need type definitions. They also default to a single entry, so 'maxItems: 1' can be dropped. adi,ad5758 is an oddball which defined an enum of arrays. While a valid schema, it is simpler as a whole to only define scalar constraints.

Pull io_uring fixes from Jens Axboe: "We got the cancelation story sorted now, so for all intents and purposes, this should be it for 5.11 outside of any potential little fixes that may come in. This contains: - task_work task state fixes (Hao, Pavel) - Cancelation fixes (me, Pavel) - Fix for an inflight req patch in this release (Pavel) - Fix for a lock deadlock issue (Pavel)" * tag 'io_uring-5.11-2021-01-29' of git://git.kernel.dk/linux-block: io_uring: reinforce cancel on flush during exit io_uring: fix sqo ownership false positive warning io_uring: fix list corruption for splice file_get io_uring: fix flush cqring overflow list while TASK_INTERRUPTIBLE io_uring: fix wqe->lock/completion_lock deadlock io_uring: fix cancellation taking mutex while TASK_UNINTERRUPTIBLE io_uring: fix __io_uring_files_cancel() with TASK_UNINTERRUPTIBLE io_uring: only call io_cqring_ev_posted() if events were posted io_uring: if we see flush on exit, cancel related tasks

The LiteX SOC controller driver makes use of IOMEM functions like devm_platform_ioremap_resource(), which are only available if CONFIG_HAS_IOMEM is defined. This causes the driver to be enable under make ARCH=um allyesconfig, even though it won't build. By adding a dependency on HAS_IOMEM, the driver will not be enabled on architectures which don't support it. Fixes: 22447a99 ("drivers/soc/litex: add LiteX SoC Controller driver") Signed-off-by:

Pull iommu fixes from Joerg Roedel: - AMD IOMMU fix to make sure features are detected before they are queried. - Intel IOMMU address alignment check fix for an IOLTB flushing command. - Performance fix for Intel IOMMU to make sure the code does not do full IOTLB flushes all the time. Those flushes are very expensive on emulated IOMMUs. * tag 'iommu-fixes-v5.11-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: iommu/vt-d: Do not use flush-queue when caching-mode is on iommu/vt-d: Correctly check addr alignment in qi_flush_dev_iotlb_pasid() iommu/amd: Use IVHD EFR for early initialization of IOMMU features

Pull power management fixes from Rafael Wysocki: "These fix a deadlock in the 'kexec jump' code and address a possible hibernation image creation issue. Specifics: - Fix a deadlock caused by attempting to acquire the same mutex twice in a row in the "kexec jump" code (Baoquan He) - Modify the hibernation image saving code to flush the unwritten data to the swap storage later so as to avoid failing to write the image signature which is possible in some cases (Laurent Badel)" * tag 'pm-5.11-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: PM: hibernate: flush swap writer after marking kernel: kexec: remove the lock operation of system_transition_mutex -

Pull ACPI fixes from Rafael Wysocki: "These fix the handling of notifications in the ACPI thermal driver and address a device enumeration issue leading to the presence of multiple 'MODALIAS=' entries in one uevent file in sysfs in some cases. Specifics: - Modify the ACPI thermal driver to avoid evaluating _TMP directly in its Notify () handler callback and running too many thermal checks for one thermal zone at the same time so as to address a work item accumulation issue observed on some systems that fail to shut down as a result of it (Rafael Wysocki) - Modify the ACPI uevent file creation code to avoid putting multiple 'MODALIAS=' entries in one uevent file in sysfs which breaks systemd-udevd (Kai-Heng Feng)" * tag 'acpi-5.11-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: ACPI: thermal: Do not call acpi_thermal_check() directly ACPI: sysfs: Prefer "compatible" modalias
