Wenchao Chen e7afa79a3b mmc: hsq: Fix data stomping during mmc recovery
The block device uses multiple queues to access emmc. There will be up to 3
requests in the hsq of the host. The current code will check whether there
is a request doing recovery before entering the queue, but it will not check
whether there is a request when the lock is issued. The request is in recovery
mode. If there is a request in recovery, then a read and write request is
initiated at this time, and the conflict between the request and the recovery
request will cause the data to be trampled.

Brian Norris e9233917a7 mmc: core: Terminate infinite loop in SD-UHS voltage switch
This loop intends to retry a max of 10 times, with some implicit
termination based on the SD_{R,}OCR_S18A bit. Unfortunately, the
termination condition depends on the value reported by the SD card
(*rocr), which may or may not correctly reflect what we asked it to do.

Needless to say, it's not wise to rely on the card doing what we expect;
we should at least terminate the loop regardless. So, check both the
input and output values, so we ensure we will terminate regardless of
the SD card behavior.

Note that SDIO learned a similar retry loop in commit 0797e5f145
("mmc: core: Fixup signal voltage switch"), but that used the 'ocr'
result, and so the current pre-terminating condition looks like:

    rocr & ocr & R4_18V_PRESENT

(i.e., it doesn't have the same bug.)

This addresses a number of crash reports seen on ChromeOS that look
like the following:

Sergei Antonov 35ca91d133 mmc: moxart: fix 4-bit bus width and remove 8-bit bus width
According to the datasheet [1] at page 377, 4-bit bus width is turned on by
bit 2 of the Bus Width Register. Thus the current bitmask is wrong: define
BUS_WIDTH_4 BIT(1)

BIT(1) does not work but BIT(2) works. This has been verified on real MOXA
hardware with FTSDC010 controller revision 1_6_0.

The corrected value of BUS_WIDTH_4 mask collides with: define BUS_WIDTH_8
BIT(2). Additionally, 8-bit bus width mode isn't supported according to the
datasheet, so let's remove the corresponding code.

Adrian Hunter 63f1560930 mmc: core: Fix inconsistent sd3_bus_mode at UHS-I SD voltage switch failure
If re-initialization results is a different signal voltage, because the
voltage switch failed previously, but not this time (or vice versa), then
sd3_bus_mode will be inconsistent with the card because the SD_SWITCH
command is done only upon first initialization.

Fix by always reading SD_SWITCH information during re-initialization, which
also means it does not need to be re-read later for the 1.8V fixup
workaround.

Note, brief testing showed SD_SWITCH took about 1.8ms to 2ms which added
about 1% to 1.5% to the re-initialization time, so it's not particularly
significant.

David Gow d52788b3da mmc: sdhci-of-aspeed: test: Fix dependencies when KUNIT=m
While the sdhci-of-aspeed KUnit tests do work when builtin, and do work
when KUnit itself is being built as a module, the two together break.

This is because the KUnit tests (understandably) depend on KUnit, so a
built-in test cannot build if KUnit is a module.

Fix this by adding a dependency on (MMC_SDHCI_OF_ASPEED=m || KUNIT=y),
which only excludes this one problematic configuration.

This was reported on a nasty openrisc-randconfig run by the kernel test
robot, though for some reason (compiler optimisations removing the test
code?) I wasn't able to reproduce it locally on x86:

Wenbin Mei cc5d169260 mmc: mtk-sd: Clear interrupts when cqe off/disable
Currently we don't clear MSDC interrupts when cqe off/disable, which led
to the data complete interrupt will be reserved for the next command.
If the next command with data transfer after cqe off/disable, we process
the CMD ready interrupt and trigger DMA start for data, but the data
complete interrupt is already exists, then SW assume that the data transfer
is complete, SW will trigger DMA stop, but the data may not be transmitted
yet or is transmitting, so we may encounter the following error:
mtk-msdc 11230000.mmc: CMD bus busy detected.

Axe Yang 527f36f5ef mmc: mediatek: add support for SDIO eint wakup IRQ
Add support for eint IRQ when MSDC is used as an SDIO host. This
feature requires SDIO device support async IRQ function. With this
feature, SDIO host can be awakened by SDIO card in suspend state,
without additional pin.

MSDC driver will time-share the SDIO DAT1 pin. During suspend, MSDC
turn off clock and switch SDIO DAT1 pin to GPIO mode. And during
resume, switch GPIO function back to DAT1 mode then turn on clock.

Some device tree property should be added or modified in MSDC node
to support SDIO eint IRQ. Pinctrls "state_eint" is mandatory. Since
this feature depends on asynchronous interrupts, "wakeup-source",
"keep-power-in-suspend" and "cap-sdio-irq" flags are necessary, and
the interrupts list should be extended(the interrupt named with
sdio_wakeup):
        &mmcX {
		...
		interrupt-names = "msdc", "sdio_wakeup";
		interrupts-extended = <...>,
                              	      <&pio xxx IRQ_TYPE_LEVEL_LOW>;
                ...
                pinctrl-names = "default", "state_uhs", "state_eint";
                ...
                pinctrl-2 = <&mmc2_pins_eint>;
                ...
                cap-sdio-irq;

This reverts three commits:
1. Revert "mmc: sdhci-msm: Add compatible string check for sdx65"
   This reverts commit 953706844f.

2. Revert "mmc: sdhci-msm: Add compatible string check for sm8150"
   This reverts commit 5acd6adb65.

3. Revert "mmc: sdhci-msm: Add SoC specific compatibles"
   This reverts commit 466614a976.

The oldest commit 466614a976 ("mmc: sdhci-msm: Add SoC specific
compatibles") did not specify what benefits such multiple compatibles
bring, therefore assume there is none.  On the other hand such approach
brings a lot of churn to driver maintenance by expecting commit for
every new compatible, even though it is already covered by the fallback.

There is really no sense in duplicating of_device_id for each
variant, which is already covered by generic compatible fallback
qcom,sdhci-msm-v4 or qcom,sdhci-msm-v5.

Due to flaws in hardware design, GL9763E takes long time to exit from L1

exit L1 state during I/O requests.

To improve I/O read/write performance and take battery life into account,
let's turn on GL9763E L1 negotiation before entering runtime suspend and
turn off GL9763E L1 negotiation while executing runtime resume. That is to
say, GL9763E will not enter L1 state when executing I/O requests and enter
L1 state when PCIe bus idle.

Kamal Dasu 97904a5985 mmc: sdhci-brcmstb: Add ability to increase max clock rate for 72116b0
The 72116B0 has improved SDIO controllers that allow the max clock
rate to be increased from a max of 100MHz to a max of 150MHz. The
driver will need to get the clock and increase it's default rate
and override the caps register, that still indicates a max of 100MHz.
The new clock will be named "sdio_freq" in the DT node's "clock-names"
list. The driver will use a DT property, "clock-frequency", to
enable this functionality and will get the actual rate in MHz
from the property to allow various speeds to be requested.

Since this fixes parsing with builtins and kunit_tool, also enable the

The test can now be run via kunit_tool with:

	--kconfig_add CONFIG_MMC_SDHCI_OF_ASPEED=y \
	'sdhci-of-aspeed'

(It may be worth adding a .kunitconfig at some point, as there are
enough dependencies to make that command scarily long.)

only a single user of that arg for all the callback implementations, which

This will also allow us to stop passing the same 'reserved' around the

Introduce acpi_device_fix_up_power_extended() for fixing up power of
a device having an ACPI companion in a manner that takes the device's
children into account and make the MMC code use it in two places
instead of walking the list of the device ACPI companion's children
directly.

This will help to eliminate the children list head from struct
acpi_device as it is redundant and it is used in questionable ways
in some places (in particular, locking is needed for walking the
list pointed to it safely, but it is often missing).

In addition, there should be no return in msdc_data_xfer_next() if
there is data need be transferred, because no matter what error occurs
here, it should continue to excute to the following mmc_request_done.
Otherwise the core layer may wait complete forever.

Adrian Hunter a051246b78 mmc: block: Fix CQE recovery reset success
The intention of the use of mmc_blk_reset_success() in
mmc_blk_cqe_recovery() was to prevent repeated resets when retrying and
getting the same error. However, that may not be the case - any amount
of time and I/O may pass before another recovery is needed, in which
case there would be no reason to deny it the opportunity to recover via
a reset if necessary. CQE recovery is expected seldom and failure to
recover (if the clear tasks command fails), even more seldom, so it is
better to allow the reset always, which can be done by calling
mmc_blk_reset_success() always.

Linus Torvalds d7227785e3 sound updates for 5.19-rc1
Not much dramatic changes at this time, but we've received quite
 a lot of changes for ASoC, while there are still a few fixes and
 quirks for usual HD- and USB-auido.  Here are some highlights.
 
 * ASoC:
 - Overhaul of endianness specification for data formats, avoiding
   needless restrictions due to CODECs
 - Initial stages of Intel AVS driver merge
 - Introduction of v4 IPC mechanism for SOF
 - TDM mode support for AK4613
 - Support for Analog Devices ADAU1361, Cirrus Logic CS35L45, Maxim
   MAX98396, MediaTek MT8186, NXP i.MX8 micfil and SAI interfaces,
   nVidia Tegra186 ASRC, and Texas Instruments TAS2764 and TAS2780
 
 * Others
 - A few regression fixes after the USB-audio endpoint management
   refactoring
 - More enhancements for Cirrus HD-audio codec support (still ongoing)
 - Addition of generic serial MIDI driver

Ulf Hansson e949dee362 mmc: core: Fix busy polling for MMC_SEND_OP_COND again
It turned out that polling period for MMC_SEND_OP_COND, that currently is
set to 1ms, still isn't sufficient. In particular a Micron eMMC on a
Beaglebone platform, is reported to sometimes fail to initialize.

Additional test, shows that extending the period to 4ms is working fine, so
let's make that change.

Arnd Bergmann f95a387cde m68k: coldfire: drop ISA_DMA_API support
After a build regression report, I took a look at possible users of
CONFIG_ISA_DMA_API on m68k and found none, which Greg confirmed. The
CONFIG_GENERIC_ISA_DMA option in turn is only needed to implement
ISA_DMA_API, and is clearly not used on the platforms with ISA support.

The CONFIG_ISA support for AMIGA_PCMCIA is probably also unneeded,
but this is less clear. Unlike other PCMCIA implementations, this one
does not use the drivers/pcmcia subsystem at all and just supports
the "apne" network driver. When it was first added, one could use
ISA drivers on it as well, but this probably broke at some point.

With no reason to keep this, let's just drop the corresponding files
and prevent the remaining ISA drivers that use this from getting built.

The remaining definitions in asm/dma.h are used for PCI support.

The ARASAN MMC controller on Keystone 3 class of devices need the SDCD

out in sdhci-of-arasan.c driver, commit 3794c54264 ("mmc:
sdhci-of-arasan: Set controller to test mode when no CD bit").

In cases where this can't be connected, add a quirk to force the
controller into test mode and set the TESTCD bit. Use the flag
"ti,fails-without-test-cd", to implement this above quirk when required.

Despite mmc_ioc_multi_cmd::num_of_cmds is a 64-bit field, its maximum
value is limited to MMC_IOC_MAX_CMDS (only 255); using a 64-bit local
variable to hold a copy of that field leads to gcc generating ineffective
loop code: despite the source code using an *int* variable for the loop
counters,  the 32-bit object code uses 64-bit unsigned counters.  Also,
gcc has to drop the most significant word of that 64-bit variable when
calling kcalloc() and assigning to mmc_queue_req::ioc_count anyway.
Using the *unsigned int* variable instead results in a better code.

Found by Linux Verification Center (linuxtesting.org) with the SVACE static
analysis tool.

Brian Norris 4bc31edebd mmc: core: Set HS clock speed before sending HS CMD13
Way back in commit 4f25580fb8 ("mmc: core: changes frequency to
hs_max_dtr when selecting hs400es"), Rockchip engineers noticed that
some eMMC don't respond to SEND_STATUS commands very reliably if they're
still running at a low initial frequency. As mentioned in that commit,
JESD84-B51 P49 suggests a sequence in which the host:
1. sets HS_TIMING
2. bumps the clock ("<= 52 MHz")
3. sends further commands

It doesn't exactly require that we don't use a lower-than-52MHz
frequency, but in practice, these eMMC don't like it.

The aforementioned commit tried to get that right for HS400ES, although
it's unclear whether this ever truly worked as committed into mainline,
as other changes/refactoring adjusted the sequence in conflicting ways:

08573eaf1a ("mmc: mmc: do not use CMD13 to get status after speed mode
switch")

53e60650f7 ("mmc: core: Allow CMD13 polling when switching to HS mode
for mmc")

In any case, today we do step 3 before step 2. Let's fix that, and also
apply the same logic to HS200/400, where this eMMC has problems too.

Resolves errors like this seen when booting some RK3399 Gru/Scarlet
systems:

[    2.058881] mmc1: CQHCI version 5.10

[    2.841751] mmc1: error -110 whilst initialising MMC card

Ealier versions of this patch bumped to 200MHz/HS200 speeds too early,
which caused issues on, e.g., qcom-msm8974-fairphone-fp2. (Thanks for
the report Luca!) After a second look, it appears that aligns with
JESD84 / page 45 / table 28, so we need to keep to lower (HS / 52 MHz)
rates first.

Arnd Bergmann 08d3df8c81 ARM: pxa: split up mach/hardware.h
The mach/hardware.h is included in lots of places, and it provides
three different things on pxa:

- the cpu_is_pxa* macros
- an indirect inclusion of mach/addr-map.h
- the __REG() and io_pv2() helper macros

Split it up into separate <linux/soc/pxa/cpu.h> and mach/pxa-regs.h
headers, then change all the files that use mach/hardware.h to
include the exact set of those three headers that they actually
need, allowing for further more targeted cleanup.

linux/soc/pxa/cpu.h can remain permanently exported and is now in
a global location along with similar headers. pxa-regs.h and
addr-map.h are only used in a very small number of drivers now
and can be moved to arch/arm/mach-pxa/ directly when those drivers
are to pass the necessary data as resources.

Michael Wu 08ebf903af mmc: core: Fixup support for writeback-cache for eMMC and SD
During the card initialization process, the mmc core checks whether the
eMMC/SD card supports an internal writeback-cache and then enables it
inside the card.

Unfortunately, this isn't according to what the mmc core reports to the
upper block layer. Instead, the writeback-cache support with REQ_FLUSH and
REQ_FUA, are being enabled depending on whether the host supports the CMD23
(MMC_CAP_CMD23) and whether an eMMC supports the reliable-write command.

This is wrong and it may also sound awkward. In fact, it's a remnant
from when both eMMC/SD cards didn't have dedicated commands/support to
control the internal writeback-cache. In other words, it was the best we
could do at that point in time.

To fix the problem, but also without breaking backwards compatibility,
let's align the REQ_FLUSH support with whether the writeback-cache became
successfully enabled - for both eMMC and SD cards.

Christian Löhle 5d43593337 mmc: block: Check for errors after write on SPI
Introduce a SEND_STATUS check for writes through SPI to not mark
an unsuccessful write as successful.

Since SPI SD/MMC does not have states, after a write, the card will
just hold the line LOW until it is ready again. The driver marks the
write therefore as completed as soon as it reads something other than
all zeroes.
The driver does not distinguish from a card no longer signalling busy
and it being disconnected (and the line being pulled-up by the host).
This lead to writes being marked as successful when disconnecting
a busy card.
Now the card is ensured to be still connected by an additional CMD13,
just like non-SPI is ensured to go back to TRAN state.

While at it and since we already poll for the post-write status anyway,
we might as well check for SPIs error bits (any of them).

The disconnecting card problem is reproducable for me after continuous
write activity and randomly disconnecting, around every 20-50 tries
on SPI DS for some card.

Yann Gautier 0d319dd5a2 mmc: mmci: stm32: correctly check all elements of sg list
Use sg and not data->sg when checking sg list elements. Else only the
first element alignment is checked.
The last element should be checked the same way, for_each_sg already set
sg to sg_next(sg).

Linus Torvalds 7203062171 TTY/Serial driver changes for 5.18-rc1
Here are the big set of tty and serial driver changes for 5.18-rc1.
 
 Nothing major, some more good cleanups from Jiri and 2 new serial
 drivers.  Highlights include:
 	- termbits cleanups
 	- export symbol cleanups and other core cleanups from Jiri Slaby
 	- new sunplus and mvebu uart drivers (amazing that people are
 	  still creating new uarts...)
 	- samsung serial driver cleanups
 	- ldisc 29 is now "reserved" for experimental/development line
 	  disciplines
 	- lots of other tiny fixes and cleanups to serial drivers and
 	  bindings
 
 All of these have been in linux-next for a while with no reported
 issues.

Linus Torvalds dfdc1de642 Staging driver update for 5.18-rc1
Here is the big set of staging driver updates for 5.18-rc1.
 
 Loads of tiny cleanups for almost all staging drivers in here, nothing
 major at all.  Highlights include:
 	- remove the ashmem Android driver.  It is long-dead and if
 	  there are any legacy userspace applications still using it,
 	  the Android kernel images will maintain it, the community
 	  shouldn't care about it anymore
 	- wfx wifi driver major cleanups.  Should be ready to merge out
 	  of staging soon, and will coordinate with the wifi maintainers
 	  after -rc1 is out
 	- major cleanups and unwinding of the layers of the r8188eu
 	  driver.  It's amazing just how many unneeded layers of
 	  abstraction is in there, just when we think it's done, another
 	  is found...
 	- lots of tiny coding style cleanups in many other staging
 	  drivers.
 
 There will be merge conflict with a fbtft change and the spi driver
 changes in your tree, but it's pretty obvious what to do (the function
 shouldn't return anything.)
 
 All have been in linux-next for a while with no reported problems.

Linus Torvalds ad9c6ee642 spi: Updates for v5.18
The overwhelming bulk of this pull request is a change from Uwe
 Kleine-König which changes the return type of the remove() function to
 void as part of some wider work he's doing to do this for all bus types,
 causing updates to most SPI device drivers.  The branch with that on has
 been cross merged with a couple of other trees which added new SPI
 drivers this cycle, I'm not expecting any build issues resulting from
 the change.
 
 Otherwise it's been a relatively quiet release with some new device
 support, a few minor features and the welcome completion of the
 conversion of the subsystem to use GPIO descriptors rather than numbers:
 
  - Change return type of remove() to void.
  - Completion of the conversion of SPI controller drivers to use GPIO
    descriptors rather than numbers.
  - Quite a few DT schema conversions.
  - Support for multiple SPI devices on a bus in ACPI systems.
  - Big overhaul of the PXA2xx SPI driver.
  - Support for AMD AMDI0062, Intel Raptor Lake, Mediatek MT7986 and
    MT8186, nVidia Tegra210 and Tegra234, Renesas RZ/V2L, Tesla FSD and
    Sunplus SP7021.

Ulf Hansson 23e1b8c15b mmc: core: Drop HS400 caps unless 8-bit bus is supported too
When mmc_select_hs400es() tries to switch to the HS400 ES mode, it may bail
out early if the host doesn't support an 8-bit buswidth, as it's required
for the HS400 mode.

To improve the situation, let's instead drop the HS400 bits from the
capability field if the 8-bit bus isn't supported. In this way, we allow
the mmc initialization to continue by trying a lower speed mode.

Even if the current WARN() notifies the user that something is severely

Ulf Hansson 3b6c472822 mmc: core: Improve fallback to speed modes if eMMC HS200 fails
In the error path of mmc_select_hs200() we are trying our best to restore
the card/host into a valid state. This makes sense, especially if we
encounter a simple switch error (-EBADMSG). However, rather than then
continue with using the legacy speed mode, let's try the other better speed
modes first. Additionally, let's update the card->mmc_avail_type to avoid
us from trying a broken HS200 mode again.

In an Amlogic S905W based TV box where the switch to HS200 mode fails for
the eMMC, this allows us to use the eMMC in DDR mode in favor of the legacy
mode, which greatly improves the performance.

Peter Geis 52c92286b7 mmc: dw-mmc-rockchip: Fix handling invalid clock rates
The Rockchip rk356x ciu clock cannot be set as low as the dw-mmc
hardware supports. This leads to a situation during card initialization
where the clock is set lower than the clock driver can support. The
dw-mmc-rockchip driver spews errors when this happens.
For normal operation this only happens a few times during boot, but when
cd-broken is enabled (in cases such as the SoQuartz module) this fires
multiple times each poll cycle.

Fix this by testing the lowest possible frequency that the clock driver
can support which is within the mmc specification. Divide that rate by
the internal divider and set f_min to this.

Commit 76bfc7ccc2 ("mmc: core: adjust polling interval for CMD1"),

To fix the problem, but also to try to keep some of the new improved

increases for each loop, according to common polling loop in
__mmc_poll_for_busy().

spi: make remove callback a void function
The value returned by an spi driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)

So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

Christian Löhle 54309fde1a mmc: block: fix read single on recovery logic
On reads with MMC_READ_MULTIPLE_BLOCK that fail,
the recovery handler will use MMC_READ_SINGLE_BLOCK for
each of the blocks, up to MMC_READ_SINGLE_RETRIES times each.
The logic for this is fixed to never report unsuccessful reads
as success to the block layer.

On command error with retries remaining, blk_update_request was
called with whatever value error was set last to.
In case it was last set to BLK_STS_OK (default), the read will be
reported as success, even though there was no data read from the device.
This could happen on a CRC mismatch for the response,
a card rejecting the command (e.g. again due to a CRC mismatch).
In case it was last set to BLK_STS_IOERR, the error is reported correctly,
but no retries will be attempted.

Greg Kroah-Hartman bd2db32e7c moxart: fix potential use-after-free on remove path
It was reported that the mmc host structure could be accessed after it
was freed in moxart_remove(), so fix this by saving the base register of
the device and using it instead of the pointer dereference.

Kai-Heng Feng 7499b529d9 mmc: rtsx: Use pm_runtime_{get,put}() to handle runtime PM
Commit 5b4258f672 ("misc: rtsx: rts5249 support runtime PM") doesn't
use pm_runtime_{get,put}() helpers when it should, so the RPM refcount
keeps at zero, hence its parent driver, rtsx_pci, has to do lots of
weird tricks to keep it from runtime suspending.

So use those helpers at right places to properly manage runtime PM.
