* Raw NAND changes:
i.MX8 and i.MX31 now have their own compatible, the Qcom driver got
cleaned, the Broadcom driver got fixed.
* SPI NAND changes:
Two main features have been added:
- OTP support has been brought, and ESMT and Micron manufacturer drivers
implement it.
- Read retry, and Macronix manufacturer driver implement it.
There is as well a bunch of minor improvements and fixes in drivers and
bindings.

SPI_QPIC_SNAND is the only driver that selects MTD instead of depending
on it, which could lead to circular dependencies. Moreover, as
SPI_QPIC_SNAND is bool, this forces MTD (and various related symbols) to
be built-in, as can be seen in an allmodconfig kernel.
Except for a missing semicolon, there is no reason why SPI_QPIC_SNAND
cannot be tristate; all MODULE_*() boilerplate is already present.
Hence make SPI_QPIC_SNAND tristate, let it depend on MTD, and add the
missing semicolon.

The conversion of the XEN specific global variable pci_msi_ignore_mask to a
MSI domain flag, missed the facts that:
1) Legacy architectures do not provide a interrupt domain
2) Parent MSI domains do not necessarily have a domain info attached
Both cases result in an unconditional NULL pointer dereference. This was
unfortunatly missed in review and testing revealed it late.
Cure this by using the existing pci_msi_domain_supports() helper, which
handles all possible cases correctly.

Previously, the condition for invalidating the tx flow in
mctp_i2c_invalidate_tx_flow() checked if `rc` was nonzero.
However, this could incorrectly trigger the invalidation
even when `rc > 0` was returned as a success status.
This patch updates the condition to explicitly check for `rc < 0`,
ensuring that only error cases trigger the invalidation.

From: Tomasz Pakuła <tomasz.pakula.oficjalny@gmail.com>
This patch series is focused on improving the compatibility and usability of the
hid-pidff force feedback driver. Last patch introduces a new, universal driver
for PID devices that need some special handling like report fixups, remapping the
button range, managing new pidff quirks and setting desirable fuzz/flat values.
This work has been done in the span of the past months with the help of the great
Linux simracing community, with a little input from sim flight fans from FFBeast.
No changes interfere with compliant and currently working PID devices.
"Generic" codepath was tested as well with Moza and Simxperience AccuForce v2.
I'm not married to the name. It's what we used previously, but if "universal" is
confusing (pidff is already the generic driver), we can come up with something
better like "hid-quirky-pidff" :)
With v8 and tiny finx in v9, all the outstanding issues were resolved,
additional pidff issues were fixed and hid-pidff defines moved to a dedicated
header file. This patch series could be considered done bar any comments and
requests from input maintainers.
I could save more then a dozen lines of code by changing simple if statements
to only occupy on line instead of two in there's a need for that.

From: Mario Limonciello <mario.limonciello@amd.com>
Some platforms include a human presence detection (HPD) sensor. When
enabled and a user is detected a wake event will be emitted from the
sensor fusion hub that software can react to.
Example use cases are "wake from suspend on approach" or to "lock
when leaving".
This is currently enabled by default on supported systems, but users
can't control it. This essentially means that wake on approach is
enabled which is a really surprising behavior to users that don't
expect it.
Instead of defaulting to enabled add a sysfs knob that users can
use to enable the feature if desirable and set it to disabled by
default.

Commit e49ad667815d ("PCI: j721e: Add TI J784S4 PCIe configuration")
assigned the value of .linkdown_irq_regfield for the J784S4 SoC as the
"LINK_DOWN" macro corresponding to BIT(1), and as a result, the Link
Down interrupts on J784S4 SoC are missed.
According to the Technical Reference Manual and Register Documentation
for the J784S4 SoC[1], BIT(1) corresponds to "ENABLE_SYS_EN_PCIE_DPA_1",
which is not the correct field for the link-state interrupt. Instead, it
is BIT(10) of the "PCIE_INTD_ENABLE_REG_SYS_2" register that corresponds
to the link-state field named as "ENABLE_SYS_EN_PCIE_LINK_STATE".
Thus, set .linkdown_irq_regfield to the macro "J7200_LINK_DOWN", which
expands to BIT(10) and was first defined for the J7200 SoC. Other SoCs
already reuse this macro since it accurately represents the "link-state"
field in their respective "PCIE_INTD_ENABLE_REG_SYS_2" register.

For PCITEST_MSI we really want to set PCITEST_SET_IRQTYPE explicitly
to PCITEST_IRQ_TYPE_MSI, since we want to test if MSI works.
For PCITEST_MSIX we really want to set PCITEST_SET_IRQTYPE explicitly
to PCITEST_IRQ_TYPE_MSIX, since we want to test if MSI works.
For PCITEST_LEGACY_IRQ we really want to set PCITEST_SET_IRQTYPE
explicitly to PCITEST_IRQ_TYPE_INTX, since we want to test if INTx
works.
However, for PCITEST_WRITE, PCITEST_READ, PCITEST_COPY, we really don't
care which IRQ type that is used, we just want to use a IRQ type that is
supported by the EPC.
The old behavior was to always use MSI for PCITEST_WRITE, PCITEST_READ,
PCITEST_COPY, was to always set IRQ type to MSI before doing the actual
test, however, there are EPC drivers that do not support MSI.
Add a new PCITEST_IRQ_TYPE_AUTO, that will use the CAPS register to see
which IRQ types the endpoint supports, and use one of the supported IRQ
types.
For backwards compatibility, if the endpoint does not expose any supported
IRQ type in the CAPS register, simply fallback to using MSI, as it was
unconditionally done before.

Neither RK3568 or RK3588 supports INTx interrupts.
Since epc_features is zero initialized, this is strictly not needed.
However, setting intx_capable explicitly to false makes it more clear
that neither RK3568 or RK3588 supports INTx interrupts.
No functional change.

Commit d40f275d96e8 ("drm/xe: Move survivability entirely to xe_pci")
tried to follow the logic: initialize everything needed and if
everything succeeds, set the flag that it's enabled. While it fixed some
corner cases of those calls failing, it was wrong for setting the flag
after the call to xe_heci_gsc_init(): that function does a different
initialization for survivability mode.
Fix that and add comments about this being done on purpose.

Commit d40f275d96e8 ("drm/xe: Move survivability entirely to xe_pci")
moved the survivability handling to be done entirely in the xe_pci
layer. However there are some issues with that approach:
1) Survivability mode needs at least the mmio initialized, otherwise it
can't really read a register to decide if it should enter that state
2) SR-IOV mode should be initialized, otherwise it's not possible to
check if it's VF
Besides, as pointed by Riana the check for
xe_survivability_mode_enable() was wrong in xe_pci_probe() since it's
not a bool return.
Fix that by moving the initialization to be entirely in the xe_device
layer, with the correct dependencies handled: only after mmio and sriov
initialization, and not triggering it on error from
wait_for_lmem_ready(). This restores the trigger behavior before that
commit. The xe_pci layer now only checks for "is it enabled?",
like it's doing in xe_pci_suspend()/xe_pci_remove(), etc.

Starting from commit 18778b5fdd01 ("drm/xe: Eliminate usage of
TIMESTAMP_OVERRIDE") we access the CTC_MODE register only to warn
if it has undocumented value. There is no point in doing that on
the VF driver. While here, move this check to a helper function.

Pull gpio updates from Bartosz Golaszewski:
"There are no new drivers this time but several changes to the core
GPIO framework and various driver updates.
This release cycle, we're starting a relatively straightforward but
tedious rework of the GPIO consumer API: for historical reasons, the
gpiod_set_value() variants would return void. Not only that but the
GPIO provider interface does not even allow drivers to return a value
to GPIO core. This is because initial GPIO controllers would be MMIO
based and could not fail. We've had I2C, SPI and USB controllers for
years too but no way of indicating failures to callers.
This changes the consumer interface, adds new provider callbacks and
starts converting the drivers under drivers/gpio/ to using them. Once
this gets upstream, we'll keep on converting GPIO drivers that live
elsewhere and once there are no more users of the old callbacks, we'll
remove them and rename the new ones to the previous name. I imagine
the last step would happen in one sweeping change like what you did
for the remove_new() -> remove() renaming.
We've also addressed an issue where invalid return values from GPIO
drivers would get propagated to user-space by adding some
GPIO-core-level sanitization. Again: not a complex change but way
overdue.
Other than that: lots of driver and core refactoring, DT-bindings
changes and some other minor changes like coding style fixes or header
reordering.
GPIO core:
- add sanitization of return values of GPIO provider callbacks so
that invalid ones don't get propagated to user-space
- add new variants of the line setter callbacks for GPIO providers
that return an integer and allow to indicate driver errors to the
GPIO core
- change the interface of all gpiod_set_value() variants to return an
integer thus becoming able to indicate failures in the underlying
layer to callers
- drop unneeded ERR_CAST in gpiolib-acpi
- use for_each_if() where applicable
- provide gpiod_multi_set_value_cansleep() as a new, simpler
interface to gpiod_set_array_value_cansleep() and use it across
several drivers treewide
- reduce the number of atomic reads of the descriptor flags in
gpiolib debugfs code
- simplify for_each_hwgpio_in_range() and
for_each_requested_gpio_in_range()
- add support for three-cell GPIO specifiers in GPIO OF code
- don't build HTE (hardware timestamp engine) GPIO code with the HTE
subsystem disabled in Kconfig
- unduplicate calls to gpiod_direction_input_nonotify()
- rework the handling of the valid_mask property of GPIO chips: don't
allow drivers to set it as it should only be handled by GPIO core
and start actually enforcing it in GPIO core for *all* drivers, not
only the ones implementing a custom request() callback
- get the `ngpios` property from the fwnode of the GPIO chip, not its
device in order to handle multi-bank GPIO chips
Driver improvements:
- convert a part of the GPIO drivers under drivers/gpio/ to using the
new value setter callbacks
- convert several drivers to using automatic lock guards from
cleanup.h
- allow building gpio-bt8xx with COMPILE_TEST=y
- refactor gpio-74x164 (use devres, cleanup helpers, __counted_by()
and bits.h macros)
- refactor gpio-latch (use generic device properties, lock guards and
some local variables for better readability)
- refactor gpio-xilinx (improve the usage of the bitmap API)
- support multiple virtual GPIO controller instances in gpio-virtio
- allow gpio-regmap to use the standard `ngpios` property from
GPIOLIB
- factor out the common code for synchronous probing of virtual GPIO
devices into its own library
- use str_enable_disable(), str_high_low() and other string helpers
where applicable
- extend the gpio-mmio abstraction layer to allow calling into the
pinctrl back-end when setting direction
- convert gpio-vf610 to using the gpio-mmio library
- use more devres in gpio-adnp
- add support for reset-gpios in gpio-pcf857x
- add support for more models to gpio-loongson-64bit
DT bindings:
- add new compatibles to gpio-vf610 and gpio-loongson
- add missing gpio-ranges property to gpio-mvebu
- add reset-gpios to nxp,pcf8575
- enable gpio-hog parsing in ast2400-gpio

- coding style improvements
- kerneldoc fixes

Changes include marking trivial Rust bindings as inlines and comment
tweaks to better reflect the LSM hooks.
- Add LSM/SELinux access controls to io_uring_allowed()
Similar to the io_uring_disabled sysctl, add a LSM hook to
io_uring_allowed() to enable LSMs a simple way to enforce security
policy on the use of io_uring. This pull request includes SELinux
support for this new control using the io_uring/allowed permission.

We've seen problems in the past where patches to the credentials code
sent by non-maintainers would often languish on the lists for
multiple months as there was no one explicitly tasked with the
responsibility of reviewing and/or merging credentials related code.
Considering that most of the code under security/ has a vested
interest in ensuring that the credentials code is well maintained,
I'm volunteering to look after the credentials code and Serge Hallyn
has also volunteered to step up as an official reviewer. I posted the
MAINTAINERS update as a RFC to LKML in hopes that someone else would
jump up with an "I'll do it!", but beyond Serge it was all crickets.

rk806_set_mode_dcdc()
If 'ctr_bit' is negative, the shift counts become negative, causing a
shift of bounds and undefined behavior.
Presumably that's not possible in normal operation, but the code
generation isn't optimal. And undefined behavior should be avoided
regardless.
Improve code generation and remove the undefined behavior by converting
the signed variables to unsigned.
Fixes the following warning with an UBSAN kernel:
vmlinux.o: warning: objtool: rk806_set_mode_dcdc() falls through to next function rk806_get_mode_dcdc()

menu governor that leads to significant improvements in some
performance benchmarks, as the governor is now more likely to predict
a shorter idle duration in some cases, and there are updates of the
core device power management code, mostly related to system suspend
and resume, that should help to avoid potential issues arising when
the drivers of devices depending on one another want to use different
optimizations.
There is also a usual collection of assorted fixes and cleanups,
including removal of some unused code.
Specifics:
- Manage sysfs attributes and boost frequencies efficiently from
cpufreq core to reduce boilerplate code in drivers (Viresh Kumar)
- Minor cleanups to cpufreq drivers (Aaron Kling, Benjamin Schneider,
Dhananjay Ugwekar, Imran Shaik, zuoqian)
- Migrate some cpufreq drivers to using for_each_present_cpu() (Jacky
Bai)
- cpufreq-qcom-hw DT binding fixes (Krzysztof Kozlowski)
- Use str_enable_disable() helper in cpufreq_online() (Lifeng Zheng)
- Optimize the amd-pstate driver to avoid cases where call paths end
up calling the same writes multiple times and needlessly caching
variables through code reorganization, locking overhaul and tracing
adjustments (Mario Limonciello, Dhananjay Ugwekar)
- Make it possible to avoid enabling capacity-aware scheduling (CAS)
in the intel_pstate driver and relocate a check for out-of-band
(OOB) platform handling in it to make it detect OOB before checking
HWP availability (Rafael Wysocki)
- Fix dbs_update() to avoid inadvertent conversions of negative
integer values to unsigned int which causes CPU frequency selection
to be inaccurate in some cases when the "conservative" cpufreq
governor is in use (Jie Zhan)
- Update the handling of the most recent idle intervals in the menu
cpuidle governor to prevent useful information from being discarded
by it in some cases and improve the prediction accuracy (Rafael
Wysocki)
- Make it possible to tell the intel_idle driver to ignore its
built-in table of idle states for the given processor, clean up the
handling of auto-demotion disabling on Baytrail and Cherrytrail
chips in it, and update its MAINTAINERS entry (David Arcari, Artem
Bityutskiy, Rafael Wysocki)
- Make some cpuidle drivers use for_each_present_cpu() instead of
for_each_possible_cpu() during initialization to avoid issues
occurring when nosmp or maxcpus=0 are used (Jacky Bai)
- Clean up the Energy Model handling code somewhat (Rafael Wysocki)
- Use kfree_rcu() to simplify the handling of runtime Energy Model
updates (Li RongQing)
- Add an entry for the Energy Model framework to MAINTAINERS as
properly maintained (Lukasz Luba)
- Address RCU-related sparse warnings in the Energy Model code
(Rafael Wysocki)
- Remove ENERGY_MODEL dependency on SMP and allow it to be selected
when DEVFREQ is set without CPUFREQ so it can be used on a wider
range of systems (Jeson Gao)
- Unify error handling during runtime suspend and runtime resume in
the core to help drivers to implement more consistent runtime PM
error handling (Rafael Wysocki)
- Drop a redundant check from pm_runtime_force_resume() and rearrange
documentation related to __pm_runtime_disable() (Rafael Wysocki)
- Rework the handling of the "smart suspend" driver flag in the PM
core to avoid issues hat may occur when drivers using it depend on
some other drivers and clean up the related PM core code (Rafael
Wysocki, Colin Ian King)
- Fix the handling of devices with the power.direct_complete flag set
if device_suspend() returns an error for at least one device to
avoid situations in which some of them may not be resumed (Rafael
Wysocki)
- Use mutex_trylock() in hibernate_compressor_param_set() to avoid a
possible deadlock that may occur if the "compressor" hibernation
module parameter is accessed during the registration of a new
ieee80211 device (Lizhi Xu)
- Suppress sleeping parent warning in device_pm_add() in the case
when new children are added under a device with the
power.direct_complete set after it has been processed by
device_resume() (Xu Yang)
- Remove needless return in three void functions related to system
wakeup (Zijun Hu)
- Replace deprecated kmap_atomic() with kmap_local_page() in the
hibernation core code (David Reaver)
- Remove unused helper functions related to system sleep (David Alan
Gilbert)
- Clean up s2idle_enter() so it does not lock and unlock CPU offline
in vain and update comments in it (Ulf Hansson)
- Clean up broken white space in dpm_wait_for_children() (Geert
Uytterhoeven)
- Update the cpupower utility to fix lib version-ing in it and memory
leaks in error legs, remove hard-coded values, and implement CPU
physical core querying (Thomas Renninger, John B. Wyatt IV, Shuah
Khan, Yiwei Lin, Zhongqiu Han)"

In cyapa_update_fw_store(), if 'count' is zero, the write to
fw_name[count-1] underflows the array.
Presumably that's not possible in normal operation, as its caller
sysfs_kf_write() already checks for zero. Regardless it's a good idea
to check for the error explicitly and avoid undefined behavior.
Fixes the following warning with an UBSAN kernel:
vmlinux.o: warning: objtool: .text.cyapa_update_fw_store: unexpected end of section
