bef64d2908 mmc: remove tmio_mmc driver
With the TMIO MFD support gone, the corresponding MMC host driver can
be removed as well. The remaining tmio_mmc_core module however is still

eca5bd666b mmc: atmel-mci: fix race between stop command and start of next command
This commit fixes a race between completion of stop command and start of a
new command.
Previously the command ready interrupt was enabled before stop command
was written to the command register. This caused the command ready
interrupt to fire immediately since the CMDRDY flag is asserted constantly
while there is no command in progress.
Consequently the command state machine will immediately advance to the
next state when the tasklet function is executed again, no matter
actual completion state of the stop command.
Thus a new command can then be dispatched immediately, interrupting and
corrupting the stop command on the CMD line.
Fix that by dropping the command ready interrupt enable before calling
atmci_send_stop_cmd. atmci_send_stop_cmd does already enable the
command ready interrupt, no further writes to ATMCI_IER are necessary.

f35ca22388 mmc: sdhci-pxav2: add optional pinctrl for SDIO IRQ workaround
The PXA168 errata recommends that the CMD signal should be detached from

e41c48b4bc mmc: sdhci-pxav2: add optional core clock
Add ability to have an optional core clock just like the pxav3 driver.
The PXA168 needs this because its SDHC controllers have separate core
and io clocks that both need to be enabled. This also correctly matches
the documented devicetree bindings for this driver.

c7c60bf628 mmc: sdhci-pxav2: change clock name to match DT bindings

52e4c32bae mmc: sdhci-esdhc-imx: only enable DAT[0] and CMD line auto tuning for SDIO device
USDHC IP has one limitation: the tuning circuit can't handle the async
sdio device interrupt correctly. When sdio device use 4 data lines,
async sdio interrupt will use the shared DAT[1], if enable auto tuning
circuit to check these 4 data lines, include the DAT[1], this circuit
will detect this interrupt, take this as data on DAT[1], and adjust the
delay cell wrongly, finally will cause the DATA/CMD CRC error.
So for SDIO device, only enable DAT[0] and CMD line for auto tuning.
To distinguish the card type during card init, involve init_card().

Merge tag 'random-6.2-rc1-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random

Pull random number generator updates from Jason Donenfeld:

 - Replace prandom_u32_max() and various open-coded variants of it,
   there is now a new family of functions that uses fast rejection
   sampling to choose properly uniformly random numbers within an
   interval:

       get_random_u32_below(ceil) - [0, ceil)
       get_random_u32_above(floor) - (floor, U32_MAX]
       get_random_u32_inclusive(floor, ceil) - [floor, ceil]

   Coccinelle was used to convert all current users of
   prandom_u32_max(), as well as many open-coded patterns, resulting in
   improvements throughout the tree.

   I'll have a "late" 6.1-rc1 pull for you that removes the now unused
   prandom_u32_max() function, just in case any other trees add a new
   use case of it that needs to converted. According to linux-next,
   there may be two trivial cases of prandom_u32_max() reintroductions
   that are fixable with a 's/.../.../'. So I'll have for you a final
   conversion patch doing that alongside the removal patch during the
   second week.

   This is a treewide change that touches many files throughout.

 - More consistent use of get_random_canary().

 - Updates to comments, documentation, tests, headers, and
   simplification in configuration.

 - The arch_get_random*_early() abstraction was only used by arm64 and
   wasn't entirely useful, so this has been replaced by code that works
   in all relevant contexts.

 - The kernel will use and manage random seeds in non-volatile EFI
   variables, refreshing a variable with a fresh seed when the RNG is
   initialized. The RNG GUID namespace is then hidden from efivarfs to
   prevent accidental leakage.

   These changes are split into random.c infrastructure code used in the
   EFI subsystem, in this pull request, and related support inside of
   EFISTUB, in Ard's EFI tree. These are co-dependent for full
   functionality, but the order of merging doesn't matter.

 - Part of the infrastructure added for the EFI support is also used for
   an improvement to the way vsprintf initializes its siphash key,
   replacing an sleep loop wart.

 - The hardware RNG framework now always calls its correct random.c
   input function, add_hwgenerator_randomness(), rather than sometimes
   going through helpers better suited for other cases.

 - The add_latent_entropy() function has long been called from the fork
   handler, but is a no-op when the latent entropy gcc plugin isn't
   used, which is fine for the purposes of latent entropy.

   But it was missing out on the cycle counter that was also being mixed
   in beside the latent entropy variable. So now, if the latent entropy
   gcc plugin isn't enabled, add_latent_entropy() will expand to a call
   to add_device_randomness(NULL, 0), which adds a cycle counter,
   without the absent latent entropy variable.

 - The RNG is now reseeded from a delayed worker, rather than on demand
   when used. Always running from a worker allows it to make use of the
   CPU RNG on platforms like S390x, whose instructions are too slow to
   do so from interrupts. It also has the effect of adding in new inputs
   more frequently with more regularity, amounting to a long term
   transcript of random values. Plus, it helps a bit with the upcoming
   vDSO implementation (which isn't yet ready for 6.2).

 - The jitter entropy algorithm now tries to execute on many different
   CPUs, round-robining, in hopes of hitting even more memory latencies
   and other unpredictable effects. It also will mix in a cycle counter
   when the entropy timer fires, in addition to being mixed in from the
   main loop, to account more explicitly for fluctuations in that timer
   firing. And the state it touches is now kept within the same cache
   line, so that it's assured that the different execution contexts will
   cause latencies.

This is applicable to Tegra186 and later chips.

Current next_tag selection will cause a large delay in some requests and
destroy the scheduling results of the block scheduling layer. Because the
issued mrq tags cannot ensure that each time is sequential, especially when
the IO load is heavy. In the fio performance test, we found that 4k random
read data was sent to mmc_hsq to start calling request_atomic It takes
nearly 200ms to process the request, while mmc_hsq has processed thousands
of other requests. So we use fifo here to ensure the first in, first out
feature of the request and avoid adding additional delay to the request.

enough. So, we enable DMA interrupts as well and make sure that both
events, DMA irq and access_end irq, have happened before finishing the

that allocated in mmc_alloc_host() will be leaked and it will lead a kernel
crash because of deleting not added device in the remove path.

So fix this by checking the return value and goto error path which will call
mmc_free_host(), besides, free_irq() also needs be called.

dc4e9e2aa8 mmc: sdhci-pci: Set PROBE_PREFER_ASYNCHRONOUS
This driver often takes on the order of 10ms to start, but in some cases
as much as 190ms. It shouldn't have many cross-device dependencies to
race with, nor racy access to shared state with other drivers, so this
should be a relatively low risk change. We've done similarly with a
variety of other MMC host drivers already.

This driver was pinpointed as part of a survey of top slowest initcalls
(i.e., are built in, and probing synchronously) on a lab of ChromeOS
systems.

4fb2786961 mmc: sdhci-esdhc-imx: reset the tuning logic before execute tuning
For standard tuning method on usdhc, the previous tuning result can
impact current tuning result, let current tuning can't set the correct
delay cell. And from the logic, this is also reasonable for manual
tuning method. So reset the tuning logic before execute tuning.
To avoid compile issue, this patch also move the esdhc_reset_tuning()
upper.

Find this issue when support SDIO WiFi in band wakeup feature. After
system resume back, will do re-tuning, but then meet data CRC error.

Do not meet this issue on SD/eMMC, because we already call
esdhc_reset_tuning() when config the legency ios, and SD/eMMC need
to re-init when system resume back, but SDIO device don't do re-init
if it has MMC_PM_KEEP_POWER pm_flags.

A long time ago the kmap_atomic API required a slot to be provided which
risked the possibility that other code might use the same slot at the
same time. Disabling interrupts prevented the possibility of an interrupt
handler doing that. However, that went away with
commit 3e4d3af501 ("mm: stack based kmap_atomic()").

Remove local_irq_{save,restore}() around sg_miter_{next,stop}().

local_irq_{save,restore}() should have been removed also.

c981cdfb99 mmc: sdhci: Fix voltage switch delay
Commit 20b92a30b5 ("mmc: sdhci: update signal voltage switch code")
removed voltage switch delays from sdhci because mmc core had been
enhanced to support them. However that assumed that sdhci_set_ios()
did a single clock change, which it did not, and so the delays in mmc
core, which should have come after the first clock change, were not
effective.

Fix by avoiding re-configuring UHS and preset settings when the clock
is turning on and the settings have not changed. That then also avoids
the associated clock changes, so that then sdhci_set_ios() does a single
clock change when voltage switching, and the mmc core delays become
effective.

To do that has meant keeping track of driver strength (host->drv_type),
and cases of reinitialization (host->reinit_uhs).

Note also, the 'turning_on_clk' restriction should not be necessary
but is done to minimize the impact of the change on stable kernels.

5d249ac37f mmc: sdhci-of-arasan: Fix SDHCI_RESET_ALL for CQHCI
SDHCI_RESET_ALL resets will reset the hardware CQE state, but we aren't
tracking that properly in software. When out of sync, we may trigger
various timeouts.

It's not typical to perform resets while CQE is enabled, but one
particular case I hit commonly enough: mmc_suspend() -> mmc_power_off().
Typically we will eventually deactivate CQE (cqhci_suspend() ->
cqhci_deactivate()), but that's not guaranteed -- in particular, if
we perform a partial (e.g., interrupted) system suspend.

The same bug was already found and fixed for two other drivers, in v5.7
and v5.9:

  5cf583f1fb ("mmc: sdhci-msm: Deactivate CQE during SDHC reset")
  df57d73276 ("mmc: sdhci-pci: Fix SDHCI_RESET_ALL for CQHCI for Intel
                 GLK-based controllers")

The latter is especially prescient, saying "other drivers using CQHCI
might benefit from a similar change, if they also have CQHCI reset by
SDHCI_RESET_ALL."

So like these other patches, deactivate CQHCI when resetting the
controller. Do this via the new sdhci_and_cqhci_reset() helper.

This patch depends on (and should not compile without) the patch
entitled "mmc: cqhci: Provide helper for resetting both SDHCI and
CQHCI".

ebb5fd38f4 mmc: cqhci: Provide helper for resetting both SDHCI and CQHCI
Several SDHCI drivers need to deactivate command queueing in their reset
hook (see sdhci_cqhci_reset() / sdhci-pci-core.c, for example), and
several more are coming.

Those reset implementations have some small subtleties (e.g., ordering
of initialization of SDHCI vs. CQHCI might leave us resetting with a
NULL ->cqe_private), and are often identical across different host
drivers.

We also don't want to force a dependency between SDHCI and CQHCI, or
vice versa; non-SDHCI drivers use CQHCI, and SDHCI drivers might support
command queueing through some other means.

So, implement a small helper, to avoid repeating the same mistakes in
different drivers. Simply stick it in a header, because it's so small it
doesn't deserve its own module right now, and inlining to each driver is
pretty reasonable.

This is marked for -stable, as it is an important prerequisite patch for
several SDHCI controller bugfixes that follow.

Pull more random number generator updates from Jason Donenfeld:
 "This time with some large scale treewide cleanups.

  The intent of this pull is to clean up the way callers fetch random
  integers. The current rules for doing this right are:

   - If you want a secure or an insecure random u64, use get_random_u64()

   - If you want a secure or an insecure random u32, use get_random_u32()

     The old function prandom_u32() has been deprecated for a while
     now and is just a wrapper around get_random_u32(). Same for
     get_random_int().

   - If you want a secure or an insecure random u16, use get_random_u16()

   - If you want a secure or an insecure random u8, use get_random_u8()

   - If you want secure or insecure random bytes, use get_random_bytes().

     The old function prandom_bytes() has been deprecated for a while
     now and has long been a wrapper around get_random_bytes()

   - If you want a non-uniform random u32, u16, or u8 bounded by a
     certain open interval maximum, use prandom_u32_max()

     I say "non-uniform", because it doesn't do any rejection sampling
     or divisions. Hence, it stays within the prandom_*() namespace, not
     the get_random_*() namespace.

     I'm currently investigating a "uniform" function for 6.2. We'll see
     what comes of that.

  By applying these rules uniformly, we get several benefits:

   - By using prandom_u32_max() with an upper-bound that the compiler
     can prove at compile-time is ≤65536 or ≤256, internally
     get_random_u16() or get_random_u8() is used, which wastes fewer
     batched random bytes, and hence has higher throughput.

   - By using prandom_u32_max() instead of %, when the upper-bound is
     not a constant, division is still avoided, because
     prandom_u32_max() uses a faster multiplication-based trick instead.

   - By using get_random_u16() or get_random_u8() in cases where the
     return value is intended to indeed be a u16 or a u8, we waste fewer
     batched random bytes, and hence have higher throughput.

  This series was originally done by hand while I was on an airplane
  without Internet. Later, Kees and I worked on retroactively figuring
  out what could be done with Coccinelle and what had to be done
  manually, and then we split things up based on that.

  So while this touches a lot of files, the actual amount of code that's
  hand fiddled is comfortably small"

6e141772e6 mmc: sdhci-sprd: Fix minimum clock limit
The Spreadtrum controller supports 100KHz minimal clock rate, which means
that the current value 400KHz is wrong.

Unfortunately this has also lead to fail to initialize some cards, which
are allowed to require 100KHz to work. So, let's fix the problem by
changing the minimal supported clock rate to 100KHz.

b78870e7f4 mmc: sdhci-tegra: Use actual clock rate for SW tuning correction
Ensure tegra_host member "curr_clk_rate" holds the actual clock rate
instead of requested clock rate for proper use during tuning correction
algorithm. Actual clk rate may not be the same as the requested clk
frequency depending on the parent clock source set. Tuning correction
algorithm depends on certain parameters which are sensitive to current
clk rate. If the host clk is selected instead of the actual clock rate,
tuning correction algorithm may end up applying invalid correction,
which could result in errors

f0c00454bf mmc: renesas_sdhi: Fix rounding errors
Due to clk rounding errors on RZ/G2L platforms, it selects a clock source
with a lower clock rate compared to a higher one.
For eg: The rounding error (533333333 Hz / 4 * 4 = 533333332 Hz < 5333333
33 Hz) selects a clk source of 400 MHz instead of 533.333333 MHz.

This patch fixes this issue by adding a margin of (1/1024) higher to
the clock rate.

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.

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:

a0753ef66c mmc: sdhci-of-dwcmshc: Re-enable support for the BlueField-3 SoC
The commit 08f3dff799 (mmc: sdhci-of-dwcmshc: add rockchip platform
support") introduces the use of_device_get_match_data() to check for some
chips. Unfortunately, it also breaks the BlueField-3 FW, which uses ACPI.

To fix the problem, let's add the ACPI match data and the corresponding
quirks to re-enable the support for the BlueField-3 SoC.

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.

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;
		keep-power-in-suspend;
		wakeup-source;
                ...
        };

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
state. The I/O performance will suffer severe impact if it often enter and
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.

b5899a3e2f mmc: sdhci-of-esdhc: Fix refcount leak in esdhc_signal_voltage_switch
of_find_matching_node() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
Add missing of_node_put() to avoid refcount leak.
of_node_put() checks null pointer.

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.

291cd54e5b mmc: sdhci-of-aspeed: test: Use kunit_test_suite() macro
The kunit_test_suite() macro is no-longer incompatible with module_add,
so its use can be reinstated.

Since this fixes parsing with builtins and kunit_tool, also enable the
test by default when KUNIT_ALL_TESTS is enabled.

The test can now be run via kunit_tool with:
	./tools/testing/kunit/kunit.py run --arch=x86_64 \
	--kconfig_add CONFIG_OF=y --kconfig_add CONFIG_OF_ADDRESS=y \
	--kconfig_add CONFIG_MMC=y --kconfig_add CONFIG_MMC_SDHCI=y \
	--kconfig_add CONFIG_MMC_SDHCI_PLTFM=y \
	--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.)

a22f18bddd ACPI / MMC: PM: Unify fixing up device power
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).

MediaTek IP requires that after dma stop, it need to wait this dma stop
bit auto-reset to 0. When bus is in high loading state, it will take a
while for the dma stop complete. If there is no waiting operation here,
when program runs to clear fifo and reset, bus will hang.

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.

The second part of the multiplatform changes now converts the

 several rebases before the merge window as bugs were found, so they
 remained separate.
 
 This has to touch a lot of drivers, in particular the touchscreen,
 pcmcia, sound and clk bits, to detach the driver files from the
 platform and board specific header files.

0163717ed5 ASoC: Updates for v5.19
This is quite a big update, partly due to the addition of some larger
 drivers (more of which is to follow since at least the AVS driver is
 still a work in progress) and partly due to Charles' work sorting out
 our handling of endianness.  As has been the case recently it's much
 more about drivers than the core.
 
  - 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

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.

clock when the bus is idle. The feature is not part of the standard

non-removable devices because they don't switch the voltage and
clock gating breaks SD Card volatge switching.

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.

32f18e5961 mmc: improve API to make clear hw_reset callback is for cards
To make it unambiguous that the hw_reset callback is for cards and not
for controllers, we add 'card' to the callback name and convert all
users in one go. We keep the argument as mmc_host, though, because the
callback is used very early when mmc_card is not yet populated.

970dc9c11a mmc: mmci: stm32: use a buffer for unaligned DMA requests
In SDIO mode, the sg list for requests can be unaligned with what the
STM32 SDMMC internal DMA can support. In that case, instead of failing,
use a temporary bounce buffer to copy from/to the sg list.
This buffer is limited to 1MB. But for that we need to also limit
max_req_size to 1MB. It has not shown any throughput penalties for
SD-cards or eMMC.

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.

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.

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.

7570fb41e4 mmc: rtsx: Let MMC core handle runtime PM
Since MMC core handles runtime PM reference counting, we can avoid doing
redundant runtime PM work in the driver. That means the only thing
commit 5b4258f672 ("misc: rtsx: rts5249 support runtime PM") misses is
to always enable runtime PM, to let its parent driver enable ASPM in the
runtime idle routine.

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.

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

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.

3ceff4ea07 sound updates for 5.17-rc1
It's a relatively calm development cycle, but still lots of updates in
 the driver side like Intel SOF.  Below are some highlights:
 
 * ALSA / ASoC core:
 - A new kselftest for ALSA control API
 - PCM NO_REWINDS support
 - Potential race fixes around control removals
 - Unify x86 SG-buffer memory allocation code
 - Cleanups and race fixes for ASoC DPCM locking
 
 * ASoC:
 - Refinements and cleanups around the delay() APIs
 - Wider use of dev_err_probe().
 - Continuing cleanups and improvements to the SOF code
 - Support for pin switches in simple-card derived cards
 - Support for AMD Renoir ACP, Asahi Kasei Microdevices AKM4375, Intel
   systems using NAU8825 and MAX98390, Mediatek MT8915, nVidia Tegra20
   S/PDIF, Qualcomm systems using ALC5682I-VS and Texas Instruments
   TLV320ADC3xxx
 
 * HD-audio / USB-audio:
 - Fix deadlock at HD-audio codec unbinding
 - Fixes for Tegra194 HD-audio, new HDA support for CS35L41 codec
 - Quirks for Lenovo and HP machines, Gigabyte mobo, Bose device
 
 * Misc:
 - Fix virmidi drain behavior
 
 Note that the merge of CS35L41 codec support is still half-baked, and
 at least one ACPI change is missing.  Although this won't hinder the
 kernel build itself, we're going to catch up before RC1.

455e73a07f We have a couple patches in the framework core this time around but
they're mostly minor cleanups and some debugfs stuff. The real work
 that's in here is the typical pile of clk driver updates and new SoC
 support. Per usual (or maybe just recent trends), Qualcomm gains a
 handful of SoC drivers additions and has the largest diffstat. After
 that there are quite a few updates to the Allwinner (sunxi) drivers to
 support modular drivers and Renesas is heavily updated to add more
 support for various clks. Overall it looks pretty normal.
 
 New Drivers:
  - Add MDMA and BDMA clks to Ingenic JZ4760 and JZ4770
  - MediaTek mt7986 SoC basic support
  - Clock and reset driver for Toshiba Visconti SoCs
  - Initial clock driver for the Exynos7885 SoC (Samsung Galaxy A8)
  - Allwinner D1 clks
  - Lan966x Generic Clock Controller driver and associated DT bindings
  - Qualcomm SDX65, SM8450, and MSM8976 GCC clks
  - Qualcomm SDX65 and SM8450 RPMh clks
 
 Updates:
  - Set suppress_bind_attrs to true for i.MX8ULP driver
  - Switch from do_div to div64_ul for throughout all i.MX drivers
  - Fix imx8mn_clko1_sels for i.MX8MN
  - Remove unused IPG_AUDIO_ROOT from i.MX8MP
  - Switch parent for audio_root_clk to audio ahb in i.MX8MP driver
  - Removal of all remaining uses of __clk_lookup() in drivers/clk/samsung
  - Refactoring of the CPU clocks registration to use common interface
  - An update of the Exynos850 driver (support for more clock domains)
    required by the E850-96 development board
  - Prep for runtime PM and generic power domains on Tegra
  - Support modular Allwinner clk drivers via platform bus
  - Lan966x clock driver extended to support clock gating
  - Add serial (SCI1), watchdog (WDT), timer (OSTM), SPI (RSPI), and
    thermal (TSU) clocks and resets on Renesas RZ/G2L
  - Rework SDHI clock handling in the Renesas R-Car Gen3 and RZ/G2 clock
    drivers, and in the Renesas SDHI driver
  - Make the Cortex-A55 (I) clock on Renesas RZ/G2L programmable
  - Document support for the new Renesas R-Car S4-8 (R8A779F0) SoC
  - Add support for the new Renesas R-Car S4-8 (R8A779F0) SoC
  - Add GPU clock and resets on Renesas RZ/G2L
  - Add clk-provider.h to various Qualcomm clk drivers
  - devm version of clk_hw_register_gate()
  - kerneldoc fixes in a couple drivers

52cc1d7f97 PM: core: Remove static qualifier in DEFINE_SIMPLE_DEV_PM_OPS macro
Keep this macro in line with the other ones. This makes it possible to
use them in the cases where the underlying dev_pm_ops structure is
exported.

Restore the "static" qualifier in the two drivers where the
DEFINE_SIMPLE_DEV_PM_OPS macro was used.

Pull power management updates from Rafael Wysocki:
 "The most signigicant change here is the addition of a new cpufreq
  'P-state' driver for AMD processors as a better replacement for the
  venerable acpi-cpufreq driver.

  There are also other cpufreq updates (in the core, intel_pstate, ARM
  drivers), PM core updates (mostly related to adding new macros for
  declaring PM operations which should make the lives of driver
  developers somewhat easier), and a bunch of assorted fixes and
  cleanups.

Pull ACPI updates from Rafael Wysocki:
 "These are usual ACPICA code updates (although there are more of them
  than in the last few releases), a noticeable EC driver update (which
  mostly consists of cleanups, though), the device enumeration quirks
  handling rework from Hans, some updates eliminating unnecessary CPU
  cache flushing in some places (processor idle and system-wide PM code)
  and a bunch of assorted cleanups and fixes.

  Specifics:

   - Update ACPICA code in the kernel to the 20211217 upstream release
     including the following changes:

e5e8b2246f mmc: mtk-sd: Assign src_clk parent to src_clk_cg for legacy DTs
In commit 3c1a884436 ("mmc: mediatek: add support of source_cg clock")
an independent cg was introduced to avoid a hardware hang issue during
clock mode switches (subsequent commits will set that clock as optional).

When this clock is not present in device-tree, any operation is being
done on src_clk's parent (calling clk_get_parent()): to simplify this
and avoid checking for src_clk_cg presence everytime, just assign the
parent clock to src_clk_cg and remove the now useless checks.

Since the MMC/SD controller in Ingenic SoCs work in half-duplex, it is
possible to use one single DMA channel for both TX and RX operations,
instead of using separate channels.

supporting bi-directional channels allow more hardware to use the
channels that would otherwise be used for the MMC/SD operation.

1a6fe7bbc7 mmc: dw_mmc: Do not wait for DTO in case of error
When running the ARTPEC-8 DWMMC IP version, and a data error interrupt
comes during a data read transfer, there is no guarantee for the data
transfer over interrupt (DTO) to come within the specified data timeout.
This case is handled by the dto_timer handler which will complete the
request with the comment:

 /*
  * If DTO interrupt does NOT come in sending data state,
  * we should notify the driver to terminate current transfer
  * and report a data timeout to the core.
  */

But since the ARTPEC-8 DWMMC IP version, supports an extended TMOUT
register which allows longer timeouts than the non ARTPEC-8 version
does, waiting for the dto_timer to complete the request in error cases
may cause the request to take significantly longer time than necessary.
This is specifically true for the failing steps during tuning of a
device.

Fix this by completing the request when the error interrupt comes. Since
this fix is specific for the ARTPEC-8, a quirk is added.

25d5417a90 mmc: dw_mmc: Add driver callbacks for data read timeout
Current dw_mci driver supports a TMOUT register which consists of a 24
bit field (TMOUT[31:8]) for the DATA_TIMEOUT. The maximum value of this
field is 0xFFFFFF, which with a 200MHz clock will give a full DRTO of:

0xFFFFFF / 200000000 => ~84 ms

However, the ARTPEC-8 SoC DWMMC IP version has a TMOUT register with an
extended DATA_TIMEOUT field, which supports longer timers for the DRTO.
In this version the DATA_TIMEOUT field is split into two, which with the
same 200MHz clock as above will allow a maximum timeout of:

((TMOUT[10:8] -1) * 0xFFFFFF + TMOUT[31:11] * 8) / 200000000 => ~587 ms

Add driver callbacks for implementation specific data timeout, and
implement callback functions for the ARTPEC-8 SoC.

During test campaign, and especially after several unbind/bind sequences,
it has been seen that the SD-card on SDMMC1 thread could freeze.
The freeze always appear on a CMD23 following a CMD19.
Checking SDMMC internal registers shows that the tuning command (CMD19)
has failed.
The freeze is then due to the delay block involved in the tuning sequence.
To correct this, clear the delay block register DLYB_CR register after
the tuning commands.

5f719948b5 mmc: spi: Add device-tree SPI IDs
Commit 5fa6863ba6 ("spi: Check we have a spi_device_id for each DT
compatible") added a test to check that every SPI driver has a
spi_device_id for each DT compatiable string defined by the driver
and warns if the spi_device_id is missing. The spi_device_id is
missing for the MMC SPI driver and the following warning is now seen.

 WARNING KERN SPI driver mmc_spi has no spi_device_id for mmc-spi-slot

Fix this by adding the necessary spi_device_id.

clk: sunxi-ng: Allow the CCU core to be built as a module
Like the individual CCU drivers, it can be beneficial for memory
consumption of cross-platform configurations to only load the CCU core
on the relevant platform. For example, a generic arm64 kernel sees the
following improvement when building the CCU core and drivers as modules:

  before:
    text      data     bss     dec       hex      filename
    13882360  5251670  360800  19494830  12977ae  vmlinux

  after:
    text      data     bss     dec       hex      filename
    13734787  5086442  360800  19182029  124b1cd  vmlinux

So the result is a 390KB total reduction in kernel image size.

The one early clock provider (sun5i) requires the core to be built in.

Now that loading the MMC driver will trigger loading the CCU core, the
MMC timing mode functions do not need a compile-time fallback.

bb6d3fa98a clk: renesas: rcar-gen3: Switch to new SD clock handling
The old SD handling code was huge and could not handle all the details
which showed up on R-Car Gen3 SoCs meanwhile. It is time to switch to
another design. Have SDnH a separate clock, use the existing divider
clocks and move the errata handling from the clock driver to the SDHI
driver where it belongs.

This patch removes the old SD handling code and switch to the new one.
This updates the SDHI driver at the same time. Because the SDHI driver
can only communicate with the clock driver via clk_set_rate(), I don't
see an alternative to this flag-day-approach, so we cross subsystems
here.

The patch sadly looks messy for the CPG lib, but it is basically a huge
chunk of code removed and smaller chunks added. It looks much better
when you just view the resulting source file.

multiple descriptors, noting that the ADMA table is sized for 4KiB chunks
anyway, so it will be big enough.

61840edc88 mmc: dw_mmc: Drop use of ->init_card() callback
For dw_mmc, the ->init_card() callback is being used to turn on/off
automatic internal clock gating for powersave, which is needed to properly
support SDIO irqs on DAT1.

However, using the ->init_card() comes with a drawback in this case, as it
means that the powersave feature becomes disabled, no matter whether the
SDIO irqs becomes turned on or not. To improve the behaviour, let's change
into using the ->enable_sdio_irq() callback instead. This works fine,
because dw_mmc uses sdio_signal_irq() to signal the irqs, thus the
->enable_sdio_irq() is never executed from within atomic context.

f85a15c5ef mmc: sdhci-omap: Fix build if CONFIG_PM_SLEEP is not set
Commit f433e8aac6 ("mmc: sdhci-omap: Implement PM runtime functions")
combined the use of runtime PM and system suspend functions but left the
ifdef CONFIG_PM_SLEEP in place causing undeclared identifier error for
sdhci_omap_runtime_suspend if CONFIG_PM_SLEEP is not enabled.

Let's fix the error by removing ifdef CONFIG_PM_SLEEP and tagging the
reset of the PM related functions with __maybe_unused.

Let's also remove the forward declaration for sdhci_omap_context_save(),
that was accidentally left from an earlier version and is no longer used.

cb77cb5abe blk-crypto: rename blk_keyslot_manager to blk_crypto_profile
blk_keyslot_manager is misnamed because it doesn't necessarily manage
keyslots.  It actually does several different things:

  - Contains the crypto capabilities of the device.

  - Provides functions to control the inline encryption hardware.
    Originally these were just for programming/evicting keyslots;
    however, new functionality (hardware-wrapped keys) will require new
    functions here which are unrelated to keyslots.  Moreover,
    device-mapper devices already (ab)use "keyslot_evict" to pass key
    eviction requests to their underlying devices even though
    device-mapper devices don't have any keyslots themselves (so it
    really should be "evict_key", not "keyslot_evict").

  - Sometimes (but not always!) it manages keyslots.  Originally it
    always did, but device-mapper devices don't have keyslots
    themselves, so they use a "passthrough keyslot manager" which
    doesn't actually manage keyslots.  This hack works, but the
    terminology is unnatural.  Also, some hardware doesn't have keyslots
    and thus also uses a "passthrough keyslot manager" (support for such
    hardware is yet to be upstreamed, but it will happen eventually).

Let's stop having keyslot managers which don't actually manage keyslots.
Instead, rename blk_keyslot_manager to blk_crypto_profile.

This is a fairly big change, since for consistency it also has to update
keyslot manager-related function names, variable names, and comments --
not just the actual struct name.  However it's still a fairly
straightforward change, as it doesn't change any actual functionality.

internal flag execute_tuning_with_clr_buf. Next time when insert SD card, all
data related commands can't get any data related interrupts, include data transfer
complete interrupt, data timeout interrupt, data CRC interrupt, data end bit interrupt.
Always trigger software timeout issue. Even reset the USDHC through bits in register
SYS_CTRL (0x2C, bit28 reset tuning, bit26 reset data, bit 25 reset command, bit 24
reset all) can't recover this. From the user's point of view, USDHC stuck, SD can't

6ab4e2eb5e mmc: sdhci-pci: Read card detect from ACPI for Intel Merrifield
Intel Merrifield platform had been converted to use ACPI enumeration.
However, the driver missed an update to retrieve card detect GPIO.
Fix it here.

Unfortunately we can't rely on CD GPIO state because there are two
different PCB designs in the wild that are using the opposite card
detection sense and there is no way to distinguish those platforms,
that's why ignore CD GPIO completely and use it only as an event.

8105c2abbf mmc: moxart: Fix reference count leaks in moxart_probe
The issue happens in several error handling paths on two refcounted
object related to the object "host" (dma_chan_rx, dma_chan_tx). In
these paths, the function forgets to decrement one or both objects'
reference count increased earlier by dma_request_chan(), causing
reference count leaks.

Fix it by balancing the refcounts of both objects in some error
handling paths. In correspondence with the changes in moxart_probe(),
IS_ERR() is replaced with IS_ERR_OR_NULL() in moxart_remove() as well.

c66e21fdc4 mmc: sdhci-omap: Check MMCHS_HL_HWINFO register for ADMA
ADMA is only available on controller instances that are connected to the
L3 interconnect and are bus mastering capable.

As the MMCHS_HL_HWINFO is in the module registers before omap registers
and sdhci registers, and the omap registers and sdhci registers can be
at different offsets depending on the SoC, let's read MMCHS_HL_HWINFO
directly.

Let's also switch to using device_property_present() while at it.

Naturally all the mainline kernel devicetree files will get updated to use

also have folks updating their kernels with custom devicetree files that
we need to consider.

53f9460e08 mmc: sdhci-omap: Restore sysconfig after reset
The sysconfig register is managed in a generic way by PM runtime for us by
the interconnect target module layer code. SDHCI_RESET_ALL also resets the
target module configuration, so we need to restore sysconfig after reset.

Note that there is no need to save and restore sysconfig during PM runtime,
the PM runtime layer will do that for us.

Not sure if this issue is a problem with the current configurations, I
noticed the issue while adding support for older TI SoCs and testing with
wlcore SDIO wlan device.

d806e334d0 mmc: sdhci-omap: Fix context restore
We need to restore context in a specified order with HCTL set in two
phases. This is similar to what omap_hsmmc_context_restore() is doing.
Otherwise SDIO can stop working on resume.

And for PM runtime and SDIO cards, we need to also save SYSCTL, IE and
ISE.

This should not be a problem currently, and these patches can be applied
whenever suitable.

c4ac38c653 mmc: mtk-sd: Add HS400 online tuning support
According to JEDEC Spec, there is no need to do tuning under HS400 mode
since the Rx signal is aligned with the DS signal. However, MediaTek's IC
need set its "DS delay" internally to ensure it can latch Rx signal
correctly.

In previous version, We provide an "hs400-ds-delay" in device tree to cover
different chipset/PCB design, and it works fine in most cases.  But, with
the development of process technology and the big VCore voltage scale
range(may have 0.7V/0.6V/0.55V), it is difficult to find a suitable
"hs400-ds-delay" to cover all of IC corner cases(SSSS/TTTT/FFFF). So that
We must have the ability to do hs400 online tuning.
