Command queuing has been reported broken on some systems based on Intel
GLK. A separate patch disables command queuing in some cases.
This patch adds a quirk for broken command queuing, which enables users
with problems to disable command queuing using sdhci module parameters for
quirks.

- SDHCI_QUIRK_BROKEN_TIMEOUT_VAL
The patches made a mistake to add them in quirks2 of sdhci_host

The stm32_sdmmc variant has build-in support for datatimeout for R1B
requests. If a corresponding IRQ is raised, this triggers the DPSM to stay
busy and remains in a non-functional state. Only a reset can bring it back
to a functional state.
Because a reset must be issued from non-atomic context, let's defer this to
be managed from a threaded IRQ handler. Besides the reset, the threaded
handler also calls mmc_request_done(), to finally complete the request.

There are a few places around the code that invert inverted and possibly

in mmc_gpiod_request_cd(). MMC_CAP2_CD_ACTIVE_HIGH is used analogously to
WP line: in GPIO mode it is used only at probe time to switch polarity, for
native mode it is left as is.

Tuning support in DDR50 speed mode was added in SD Specifications Part1
Physical Layer Specification v3.01. Its not possible to distinguish
between v3.00 and v3.01 from the SCR and that is why since
commit 4324f6de6d ("mmc: core: enable CMD19 tuning for DDR50 mode")
tuning failures are ignored in DDR50 speed mode.
Cards compatible with v3.00 don't respond to CMD19 in DDR50 and this
error gets printed during enumeration and also if retune is triggered at
any time during operation. Update the printk level to pr_debug so that

The code in mmc_spi_initsequence() tries to send a burst with
high chipselect and for this reason hardcodes the device into
SPI_CS_HIGH.
This is not good because the SPI_CS_HIGH flag indicates
logical "asserted" CS not always the physical level. In
some cases the signal is inverted in the GPIO library and
in that case SPI_CS_HIGH is already set, and enforcing
SPI_CS_HIGH again will actually drive it low.
Instead of hard-coding this, toggle the polarity so if the
default is LOW it goes high to assert chipselect but if it
is already high then toggle it low instead.

In the SAM9x60 SoC, there are only two clocks instead of three for the
SDHCI device. The base clk is no longer provided, it is generated
internally from the mult clk.
The values of the base clk and mul in the capabilities registers may not
reflect the reality as the mult clk is a programmable clock which can take
several rates. As we can't trust those values, take them from the clock
tree and update the capabilities according to.
As we can have the same pitfall, in some cases, with the SAMA5D2 Soc,
stop relying on capabilities too.

This reverts commit 5dd1955225.
First, the fix seems to be plain wrong, since the erratum suggests
waiting 5ms before setting setting SYSCTL[RSTD], but this msleep()
happens after the call of sdhci_reset() which is where that bit gets
set (if SDHCI_RESET_DATA is in mask).
Second, walking the whole device tree to figure out if some node has a
"fsl,p2020-esdhc" compatible string is hugely expensive - about 70 to
100 us on our mpc8309 board. Walking the device tree is done under a
raw_spin_lock, so this is obviously really bad on an -rt system, and a
waste of time on all.
In fact, since esdhc_reset() seems to get called around 100 times per
second, that mpc8309 now spends 0.8% of its time determining that
it is not a p2020. Whether those 100 calls/s are normal or due to some
other bug or misconfiguration, regularly hitting a 100 us
non-preemptible window is unacceptable.

Here is the "big" set of driver core patches for 5.5-rc1
There's a few minor cleanups and fixes in here, but the majority of the
patches in here fall into two buckets:
- debugfs api cleanups and fixes
- driver core device link support for boot dependancy issues
The debugfs api cleanups are working to slowly refactor the debugfs apis
so that it is even harder to use incorrectly. That work has been
happening for the past few kernel releases and will continue over time,
it's a long-term project/goal
The driver core device link support missed 5.4 by just a bit, so it's
been sitting and baking for many months now. It's from Saravana Kannan
to help resolve the problems that DT-based systems have at boot time
with dependancy graphs and kernel modules. Turns out that no one has
actually tried to build a generic arm64 kernel with loads of modules and
have it "just work" for a variety of platforms (like a distro kernel)
The big problem turned out to be a lack of depandancy information
between different areas of DT entries, and the work here resolves that
problem and now allows devices to boot properly, and quicker than a
monolith kernel.
All of these patches have been in linux-next for a long time with no
reported issues.

Pull MMC updates from Ulf Hansson:
"These are the updates for MMC and MEMSTICK for v5.5.
Note that this also contains quite some additional changes reaching
beyond both the MMC and MEMSTICK subsystems. This is primarily because
of fixing an old regression for a WiFi driver based on the SDIO
interface on an OMAP openpandora board
MMC core:
- Add CMD13 polling for MMC IOCTLS with R1B response.
- Add common DT properties for clk-phase-delays for various speed
modes.
- Fix size overflow for mmc gp-partitions.
- Re-work HW reset for SDIO cards, which also includes a re-work for
Marvell's WiFi mwifiex SDIO func driver.
MMC host:
- jz4740: Add support for X1000 and JZ4760.
- jz4740: Add support for 8-bit bus and for low power mode.
- mmci: Add support for HW busy timeout for the stm32_sdmmc variant.
- owl-mmc: Add driver for Actions Semi Owl SoCs SD/MMC controller.
- renesas_sdhi: Add support for r8a774b1.

- sdhci-of-arasan: Add support for Intel LGM SDXC.
- sdhci-of-aspeed: Allow inversion of the internal card detect
signal.
- sdhci-of-esdhc: Fixup workaround for erratum A-008171 for tunings.
- sdhci-of-at91: Improve support for calibration.
- sdhci-pci: Add support for Intel JSL.
- sdhci-pci: Add quirk for AMD SDHC Device 0x7906.
- tmio: Enable support for erase/discard/trim requests.
MMC/OMAP/pandora/wl1251:
The TI wl1251 WiFi driver for SDIO on the OMAP openpandora board has
been broken since v4.7. To fix the problems, changes have been made
cross subsystems, but also to OMAP2 machine code and to openpandora
DTS files, as summarized below. Relevant changes have been tagged for
stable.
- mmc/wl1251: Re-introduce lost SDIO quirks and vendor-id for wl1251

This reverts commit 7a7dab2370. We found
out that there is still a race with RuntimePM. This can lead to a hang
when accessing the eMMC in some situations. Revert this change until the
RPM issue is fixed.
