552bc46484 dt-bindings: mmc: mmci: Add st,stm32-sdmmc2 compatible
Although this compatible is not used in kernel, as we use the common
MMCI driver, it is used by bootloaders. The U-Boot driver was merged
before the kernel driver and uses this compatible.

To avoid issues when aligning device tree files between kernel and
boot loader, the ST dedicated compatible is added to bindings file.

f89b548ca6 mmc: meson-mx-sdhc: Set MANUAL_STOP for multi-block SDIO commands
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

66c915d09b mmc: core: Disable card detect during shutdown
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.

The TMOUT register is always set with a full value for every transfer,
which (with a 200MHz clock) will give a full DRTO of ~84 milliseconds.
This is normally good enough to complete the request, but setting a full

testing data read times on different SD cards.

Add a function to set any value smaller than the maximum of 0xFFFFFF.

76bfc7ccc2 mmc: core: adjust polling interval for CMD1
In mmc_send_op_cond(), loops are continuously performed at the same
interval of 10 ms.  However the behaviour is not good for some eMMC
which can be out from a busy state earlier than 10 ms if normal.

Rather than fixing about the interval time in mmc_send_op_cond(),
let's instead convert into using the common __mmc_poll_for_busy().

The reason for adjusting the interval time is that it is important
to reduce the eMMC initialization time, especially in devices that
use eMMC as rootfs.

187b164945 mmc: core: transplant ti,wl1251 quirks from to be retired omap_hsmmc
The TiWi WL1251 WiFi chip needs special setup of the sdio
interface before it can be probed.

So far, this is done in omap_hsmmc_init_card() in omap_hsmmc.c
which makes it useable only if connected to omap devices
which use the omap_hsmmc. The OpenPandora is the most promient
example.

There are plans to switch to a newer sdhci-omap driver and
retire omap_hsmmc. Hence this quirk must be reworked or moved
somewhere else. Ideally to some location that is not dependent
on the specific SoC mmc host driver.

This is achieved by the new mmc_fixup_device() option introduced
by ("mmc: allow to match the device tree to apply quirks") to match
through device tree compatible string.

This quirk will be called early right after where host->ops->init_card()
and thus omap_hsmmc_init_card() was previously called.

Note that we do not need to transplant

	card->ocr = 0x80;

because we rely on ("mmc: core: Fixup storing of OCR for MMC_QUIRK_NONSTD_SDIO").

8c3e5b74b9 mmc: core: Fixup storing of OCR for MMC_QUIRK_NONSTD_SDIO
The mmc core takes a specific path to support initializing of a
non-standard SDIO card. This is triggered by looking for the card-quirk,
MMC_QUIRK_NONSTD_SDIO.

In mmc_sdio_init_card() this gets rather messy, as it causes the code to
bail out earlier, compared to the usual path. This leads to that the OCR
doesn't get saved properly in card->ocr. Fortunately, only omap_hsmmc has
been using the MMC_QUIRK_NONSTD_SDIO and is dealing with the issue, by
assigning a hardcoded value (0x80) to card->ocr from an ->init_card() ops.

To make the behaviour consistent, let's instead rely on the core to save
the OCR in card->ocr during initialization.

This allows to add quirks based on device tree instead of having

And we call mmc_fixup_device(sdio_card_init_methods) just after
where host->ops->init_card() can be optionally called.

b360b11026 mmc: core: allow to match the device tree to apply quirks
MMC subsystem provides a way to apply quirks when a device match some
properties (VID, PID, etc...) Unfortunately, some SDIO devices do not
comply with the SDIO specification and does not provide reliable VID/PID
(eg. Silabs WF200).

So, the drivers for these devices rely on device tree to identify the
device.

This patch allows the MMC to also rely on the device tree to apply a
quirk.

When CMD13 is sent after switching to HS400ES mode, the bus
is operating at either MMC_HIGH_26_MAX_DTR or MMC_HIGH_52_MAX_DTR.
To meet Tegra SDHCI requirement at HS400ES mode, force SDHCI
interface clock to MMC_HS200_MAX_DTR (200 MHz) so that host
controller CAR clock and the interface clock are rate matched.

The checks performed by commit aed9d65ac3 ("USB: validate
wMaxPacketValue entries in endpoint descriptors") require that initial
value of the maxp variable contains both maximum packet size bits
(10..0) and multiple-transactions bits (12..11). However, the existing
code assings only the maximum packet size bits. This patch assigns all
bits of wMaxPacketSize to the variable.

Merge tag 'xfs-5.16-fixes-3' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux

Pull xfs fix from Darrick Wong:
 "This fixes a race between a readonly remount process and other
  processes that hold a file IOLOCK on files that previously experienced
  copy on write, that could result in severe filesystem corruption if
  the filesystem is then remounted rw.

  I think this is fairly rare (since the only reliable reproducer I have
  that fits the second criteria is the experimental xfs_scrub program),
  but the race is clear, so we still need to fix this.

  Summary:

   - Fix a data corruption vector that can result from the ro remount
     process failing to clear all speculative preallocations from files
     and the rw remount process not noticing the incomplete cleanup"

Pull percpu fixes from Dennis Zhou:
 "This contains a fix for SMP && !MMU archs for percpu which has been
  tested by arm and sh. It seems in the past they have gotten away with
  it due to mapping of vm functions to km functions, but this fell apart
  a few releases ago and was just reported recently.

  The other is just a minor dependency clean up.

  I think queued up right now by Andrew is a fix in percpu that papers
  of what seems to be a bug in hotplug for a special situation with
  memoryless nodes. Michal Hocko is digging into it further"

2acdaf59e5 Here's a collection of clk driver fixes.
- Fix qcom mux logic to look at the proper parent table member.
    Luckily this clk type isn't very common.
 
  - Don't kill clks on qcom systems that use Trion PLLs that are
    enabled out of the bootloader. We will simply skip programming
    the PLL rate if it's already done.
 
  - Use the proper clk_ops for the qcom sm6125 ICE clks.
 
  - Use module_platform_driver() in i.MX as it can be a module.
 
  - Fix a UAF in the versatile clk driver on an error path.
