"For this release we have an extension of the pwrseq-pcie-m2 driver
with support for PCIe M.2 Key E connectors.

The rest of the commits fulfill a supporting role: document the
hardware in DT bindings, provide required serdev helpers (this has
been provided in an immutable branch to Rob Herring so you may see it
in his PR as well) and is followed up by some Kconfig fixes from Arnd.

Summary:

- add support for the PCIe M.2 Key E connectors in pwrseq-pcie-m2

- describe PCIe M.2 Mechanical Key E connectors in DT bindings

- add serdev helpers for looking up devices by OF nodes

- minor serdev core rework to enable support for PCIe M.2 Key E
connectors"

Merge tag 'gpio-updates-for-v7.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux

Pull gpio updates from Bartosz Golaszewski:
"For this merge window we have two new drivers: support for
GPIO-signalled ACPI events on Intel platforms and a generic
GPIO-over-pinctrl driver using the ARM SCMI protocol for
controlling pins.

Several things have been reworked in GPIO core: we unduplicated GPIO
hog handling, reduced the number of SRCU locks and dereferences,
improved support for software-node-based lookup and removed more
legacy code after converting remaining users to modern alternatives.

There's also a number of driver reworks and refactoring, documentation
updates, some bug-fixes and new tests.

GPIO core:
- defer probe on software node lookups when the remote software node
exists but has not been registered as a firmware node yet
- unify GPIO hog handling by moving code duplicated in OF and ACPI
modules into GPIO core and allow setting up hogs with software
nodes
- allow matching GPIO controllers by secondary firmware node if
matching by primary does not succeed
- demote deferral warnings to debug level as they are quite normal
when using software nodes which don't support fw_devlink yet
- disable the legacy GPIO character device uAPI v1 supprt in Kconfig
by default
- rework several core functions in preparation for the upcoming
Revocable helper library for protecting resources against sudden
removal, this reduces the number of SRCU dereferences in GPIO core
- simplify file descriptor logic in GPIO character device code by
using FD_PREPARE()
- introduce a header defining symbols used by both GPIO consumers and
providers to avoid having to include provider-specific headers from
drivers which only consume GPIOs
- replace snprintf() with strscpy() where formatting is not required

New drivers:
- add the gpio-by-pinctrl generic driver using the ARM SCMI protocol
to control GPIOs (along with SCMI changes pulled from the pinctrl
tree)
- add a driver providing support for handling of platform events via
GPIO-signalled ACPI events (used on Intel Nova Lake and later
platforms)

Driver changes:
- extend the gpio-kempld driver with support for more recent models,
interrupts and setting/getting multiple values at once
- improve interrupt handling in gpio-brcmstb
- add support for multi-SoC systems in gpio-tegra186
- make sure we return correct values from the .get() callbacks in
several GPIO drivers by normalizing any values other than 0, 1 or
negative error numbers
- use flexible arrays in several drivers to reduce the number of
required memory allocations
- simplify synchronous waiting for virtual drivers to probe and
remove the dedicated, a bit overengineered helper library
dev-sync-probe
- remove unneeded Kconfig dependencies on OF_GPIO in several drivers
and subsystems
- convert the two remaining users of of_get_named_gpio() to using
GPIO descriptors and remove the (no longer used) function along
with the header that declares it
- add missing includes in gpio-mmio
- shrink and simplify code in gpio-max732x by using guard(mutex)
- remove duplicated code handling the 'ngpios' property from
gpio-ts4800, it's already handled in GPIO core
- use correct variable type in gpio-aspeed
- add support for a new model in gpio-realtek-otto
- allow to specify the active-low setting of simulated hogs over the
configfs interface (in addition to existing devicetree support) in
gpio-sim

Bug fixes:
- clear the OF_POPULATED flag on hog nodes in GPIO chip remove path
on OF systems
- fix resource leaks in error path in gpiochip_add_data_with_key()
- drop redundant device reference in gpio-mpsse

Tests:
- add selftests for use-after-free cases in GPIO character device
code

DT bindings:
- add a DT binding document for SCMI based, gpio-over-pinctrl devices
- fix interrupt description in microchip,mpfs-gpio
- add new compatible for gpio-realtek-otto
- describe the resets of the mpfs-gpio controller
- fix maintainer's email in gpio-delay bindings
- remove the binding document for cavium,thunder-8890 as the
corresponding device is bound over PCI and not firmware nodes

Documentation:
- update the recommended way of converting legacy boards to using
software nodes for GPIO description
- describe GPIO line value semantics
- misc updates to kerneldocs

Misc:
- convert OMAP1 ams-delta board to using GPIO hogs described with
software nodes"

Merge tag 'pm-7.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull power management updates from Rafael Wysocki:
"Once again, cpufreq is the most active development area, mostly
because of the new feature additions and documentation updates in the
amd-pstate driver, but there are also changes in the cpufreq core
related to boost support and other assorted updates elsewhere.

Next up are power capping changes due to the major cleanup of the
Intel RAPL driver.

On the cpuidle front, a new C-states table for Intel Panther Lake is
added to the intel_idle driver, the stopped tick handling in the menu
and teo governors is updated, and there are a couple of cleanups.

Apart from the above, support for Tegra114 is added to devfreq and
there are assorted cleanups of that code, there are also two updates
of the operating performance points (OPP) library, two minor updates
related to hibernation, and cpupower utility man pages updates and
cleanups.

Specifics:

- Update qcom-hw DT bindings to include Eliza hardware (Abel Vesa)

Shenoy, Mario Limonciello)

- Fix sysfs files being present when HW missing and broken/outdated
documentation in the amd-pstate driver (Ninad Naik, Gautham Shenoy)

- Pass the policy to cpufreq_driver->adjust_perf() to avoid using
cpufreq_cpu_get() in the .adjust_perf() callback in amd-pstate
which leads to a scheduling-while-atomic bug (K Prateek Nayak)

- Clean up dead code in Kconfig for cpufreq (Julian Braha)

- Remove max_freq_req update for pre-existing cpufreq policy and add
a boost_freq_req QoS request to save the boost constraint instead
of overwriting the last scaling_max_freq constraint (Pierre
Gondois)

- Embed cpufreq QoS freq_req objects in cpufreq policy so they all
are allocated in one go along with the policy to simplify lifetime
rules and avoid error handling issues (Viresh Kumar)

- Use DMI max speed when CPPC is unavailable in the acpi-cpufreq
scaling driver (Henry Tseng)

- Switch policy_is_shared() in cpufreq to using cpumask_nth() instead
of cpumask_weight() because the former is more efficient (Yury
Norov)

- Use sysfs_emit() in sysfs show functions for cpufreq governor
attributes (Thorsten Blum)

- Update intel_pstate to stop returning an error when "off" is
written to its status sysfs attribute while the driver is already
off (Fabio De Francesco)

- Include current frequency in the debug message printed by
__cpufreq_driver_target() (Pengjie Zhang)

OPP debugfs (Manivannan Sadhasivam)

- Fix scoped_guard in dev_pm_opp_xlate_required_opp() (Viresh Kumar)

- Return -ENODATA if the snapshot image is not loaded (Alberto
Garcia)

- Remove inclusion of crypto/hash.h from hibernate_64.c on x86 (Eric
Biggers)

- Clean up and rearrange the intel_rapl power capping driver to make
the respective interface drivers (TPMI, MSR, and MMOI) hold their
own settings and primitives and consolidate PL4 and PMU support
flags into rapl_defaults (Kuppuswamy Sathyanarayanan)

- Correct kernel-doc function parameter names in the power capping
core code (Randy Dunlap)

- Remove unneeded casting for HZ_PER_KHZ in devfreq (Andy Shevchenko)

- Use _visible attribute to replace create/remove_sysfs_files() in
devfreq (Pengjie Zhang)

- Add Tegra114 support to activity monitor device in tegra30-devfreq
as a preparation to upcoming EMC controller support (Svyatoslav
Ryhel)

- Fix mistakes in cpupower man pages, add the boost and epp options
to the cpupower-frequency-info man page, and add the perf-bias
option to the cpupower-info man page (Roberto Ricci)

- Remove unnecessary extern declarations from getopt.h in arguments
parsing functions in cpufreq-set, cpuidle-info, cpuidle-set,
cpupower-info, and cpupower-set utilities (Kaushlendra Kumar)"

Merge tag 'acpi-7.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull ACPI support updates from Rafael Wysocki:
"These include an update of the CMOS RTC driver and the related ACPI
and x86 code that, among other things, switches it over to using the
platform device interface for device binding on x86 instead of the PNP
device driver interface (which allows the code in question to be
simplified quite a bit), a major update of the ACPI Time and Alarm
Device (TAD) driver adding an RTC class device interface to it, and
updates of core ACPI drivers that remove some unnecessary and not
really useful code from them.

Apart from that, two drivers are converted to using the platform
driver interface for device binding instead of the ACPI driver one,
which is slated for removal, support for the Performance Limited
register is added to the ACPI CPPC library and there are some
janitorial updates of it and the related cpufreq CPPC driver, the ACPI
processor driver is fixed and cleaned up, and NVIDIA vendor CPER
record handler is added to the APEI GHES code.

Also, the interface for obtaining a CPU UID from ACPI is consolidated
across architectures and used for fixing a problem with the PCI TPH
Steering Tag on ARM64, there are two updates related to ACPICA, a
minor ACPI OS Services Layer (OSL) update, and a few assorted updates
related to ACPI tables parsing.

Specifics:

- Update maintainers information regarding ACPICA (Rafael Wysocki)

- Replace strncpy() with strscpy_pad() in acpi_ut_safe_strncpy()
(Kees Cook)

- Trigger an ordered system power off after encountering a fatal
error operator in AML (Armin Wolf)

- Enable ACPI FPDT parsing on LoongArch (Xi Ruoyao)

- Remove the temporary stop-gap acpi_pptt_cache_v1_full structure
from the ACPI PPTT parser (Ben Horgan)

- Add support for exposing ACPI FPDT subtables FBPT and S3PT (Nate
DeSimone)

- Address multiple assorted issues and clean up the code in the ACPI
processor idle driver (Huisong Li)

- Replace strlcat() in the ACPI processor idle drive with a better
alternative (Andy Shevchenko)

- Rearrange and clean up acpi_processor_errata_piix4() (Rafael
Wysocki)

- Move reference performance to capabilities and fix an uninitialized
variable in the ACPI CPPC library (Pengjie Zhang)

- Add support for the Performance Limited Register to the ACPI CPPC
library (Sumit Gupta)

- Add cppc_get_perf() API to read performance controls, extend
cppc_set_epp_perf() for FFH/SystemMemory, and make the ACPI CPPC
library warn on missing mandatory DESIRED_PERF register (Sumit
Gupta)

- Modify the cpufreq CPPC driver to update MIN_PERF/MAX_PERF in
target callbacks to allow it to control performance bounds via
standard scaling_min_freq and scaling_max_freq sysfs attributes and
add sysfs documentation for the Performance Limited Register to it
(Sumit Gupta)

- Add ACPI support to the platform device interface in the CMOS RTC
driver, make the ACPI core device enumeration code create a
platform device for the CMOS RTC, and drop CMOS RTC PNP device
support (Rafael Wysocki)

- Consolidate the x86-specific CMOS RTC handling with the ACPI TAD
driver and clean up the CMOS RTC ACPI address space handler (Rafael
Wysocki)

- Enable ACPI alarm in the CMOS RTC driver if advertised in ACPI FADT
and allow that driver to work without a dedicated IRQ if the ACPI
alarm is used (Rafael Wysocki)

- Clean up the ACPI TAD driver in various ways and add an RTC class
device interface, including both the RTC setting/reading and alarm
timer support, to it (Rafael Wysocki)

- Clean up the ACPI AC and ACPI PAD (processor aggregator device)
drivers (Rafael Wysocki)

- Rework checking for duplicate video bus devices and consolidate
pnp.bus_id workarounds handling in the ACPI video bus driver
(Rafael Wysocki)

- Update the ACPI core device drivers to stop setting
acpi_device_name() unnecessarily (Rafael Wysocki)

- Rearrange code using acpi_device_class() in the ACPI core device
drivers and update them to stop setting acpi_device_class()
unnecessarily (Rafael Wysocki)

- Define ACPI_AC_CLASS in one place (Rafael Wysocki)

- Convert the ni903x_wdt watchdog driver and the xen ACPI PAD driver
to bind to platform devices instead of ACPI devices (Rafael
Wysocki)

- Add devm_ghes_register_vendor_record_notifier(), use it in the PCI
hisi driver, and Add NVIDIA vendor CPER record handler (Kai-Heng
Feng)

- Consolidate the interface for obtaining a CPU UID from ACPI across
architectures and use it to address incorrect PCI TPH Steering Tag
on ARM64 resulting from the invalid assumption that the ACPI
Processor UID would always be the same as the corresponding logical
CPU ID in Linux (Chengwen Feng)"

Merge tag 'driver-core-7.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/driver-core/driver-core

Pull driver core updates from Danilo Krummrich:
"debugfs:
- Fix NULL pointer dereference in debugfs_create_str()
- Fix misplaced EXPORT_SYMBOL_GPL for debugfs_create_str()
- Fix soundwire debugfs NULL pointer dereference from uninitialized
firmware_file

device property:
- Make fwnode flags modifications thread safe; widen the field to
unsigned long and use set_bit() / clear_bit() based accessors
- Document how to check for the property presence

devres:
- Separate struct devres_node from its "subclasses" (struct devres,
struct devres_group); give struct devres_node its own release and
free callbacks for per-type dispatch
- Introduce struct devres_action for devres actions, avoiding the
ARCH_DMA_MINALIGN alignment overhead of struct devres
- Export struct devres_node and its init/add/remove/dbginfo
primitives for use by Rust Devres<T>
- Fix missing node debug info in devm_krealloc()
- Use guard(spinlock_irqsave) where applicable; consolidate unlock
paths in devres_release_group()

driver_override:
- Convert PCI, WMI, vdpa, s390/cio, s390/ap, and fsl-mc to the
generic driver_override infrastructure, replacing per-bus
driver_override strings, sysfs attributes, and match logic; fixes a
potential UAF from unsynchronized access to driver_override in bus
match() callbacks
- Simplify __device_set_driver_override() logic

kernfs:
- Send IN_DELETE_SELF and IN_IGNORED inotify events on kernfs file
and directory removal
- Add corresponding selftests for memcg

platform:
- Allow attaching software nodes when creating platform devices via a
new 'swnode' field in struct platform_device_info
- Add kerneldoc for struct platform_device_info

software node:
- Move software node initialization from postcore_initcall() to
driver_init(), making it available early in the boot process
- Move kernel_kobj initialization (ksysfs_init) earlier to support
the above
- Remove software_node_exit(); dead code in a built-in unit

SoC:
- Introduce of_machine_read_compatible() and of_machine_read_model()
OF helpers and export soc_attr_read_machine() to replace direct
accesses to of_root from SoC drivers; also enables
CONFIG_COMPILE_TEST coverage for these drivers

sysfs:
- Constify attribute group array pointers to
'const struct attribute_group *const *' in sysfs functions,
device_add_groups() / device_remove_groups(), and struct class

Rust:
- Devres:
- Embed struct devres_node directly in Devres<T> instead of going
through devm_add_action(), avoiding the extra allocation and the
unnecessary ARCH_DMA_MINALIGN alignment

- I/O:
- Turn IoCapable from a marker trait into a functional trait
carrying the raw I/O accessor implementation (io_read /
io_write), providing working defaults for the per-type Io
methods
- Add RelaxedMmio wrapper type, making relaxed accessors usable in
code generic over the Io trait
- Remove overloaded per-type Io methods and per-backend macros
from Mmio and PCI ConfigSpace

- I/O (Register):
- Add IoLoc trait and generic read/write/update methods to the Io
trait, making I/O operations parameterizable by typed locations
- Add register! macro for defining hardware register types with
typed bitfield accessors backed by Bounded values; supports
direct, relative, and array register addressing
- Add write_reg() / try_write_reg() and LocatedRegister trait
- Update PCI sample driver to demonstrate the register! macro

Example:

```
register! {
/// UART control register.
CTRL(u32) @ 0x18 {
/// Receiver enable.
19:19 rx_enable => bool;
/// Parity configuration.
14:13 parity ?=> Parity;
}

/// FIFO watermark and counter register.
WATER(u32) @ 0x2c {
/// Number of datawords in the receive FIFO.
26:24 rx_count;
/// RX interrupt threshold.
17:16 rx_water;
}
}

impl WATER {
fn rx_above_watermark(&self) -> bool {
self.rx_count() > self.rx_water()
}
}

fn init(bar: &pci::Bar<BAR0_SIZE>) {
let water = WATER::zeroed()
.with_const_rx_water::<1>(); // > 3 would not compile
bar.write_reg(water);

let ctrl = CTRL::zeroed()
.with_parity(Parity::Even)
.with_rx_enable(true);
bar.write_reg(ctrl);
}

fn handle_rx(bar: &pci::Bar<BAR0_SIZE>) {
if bar.read(WATER).rx_above_watermark() {
// drain the FIFO
}
}

fn set_parity(bar: &pci::Bar<BAR0_SIZE>, parity: Parity) {
bar.update(CTRL, |r| r.with_parity(parity));
}
```

- IRQ:
- Move 'static bounds from where clauses to trait declarations for
IRQ handler traits

- Misc:
- Enable the generic_arg_infer Rust feature
- Extend Bounded with shift operations, single-bit bool
conversion, and const get()

Misc:
- Make deferred_probe_timeout default a Kconfig option
- Drop auxiliary_dev_pm_ops; the PM core falls back to driver PM
callbacks when no bus type PM ops are set
- Add conditional guard support for device_lock()
- Add ksysfs.c to the DRIVER CORE MAINTAINERS entry

Merge tag 'libcrypto-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/linux

Pull crypto library updates from Eric Biggers:

- Migrate more hash algorithms from the traditional crypto subsystem to
lib/crypto/

Like the algorithms migrated earlier (e.g. SHA-*), this simplifies
the implementations, improves performance, enables further
simplifications in calling code, and solves various other issues:

- AES CBC-based MACs (AES-CMAC, AES-XCBC-MAC, and AES-CBC-MAC)

- Support these algorithms in lib/crypto/ using the AES library
and the existing arm64 assembly code

- Reimplement the traditional crypto API's "cmac(aes)",
"xcbc(aes)", and "cbcmac(aes)" on top of the library

- Convert mac80211 to use the AES-CMAC library. Note: several
other subsystems can use it too and will be converted later

- Drop the broken, nonstandard, and likely unused support for
"xcbc(aes)" with key lengths other than 128 bits

- Enable optimizations by default

- GHASH

- Migrate the standalone GHASH code into lib/crypto/

- Integrate the GHASH code more closely with the very similar
POLYVAL code, and improve the generic GHASH implementation to
resist cache-timing attacks and use much less memory

- Reimplement the AES-GCM library and the "gcm" crypto_aead
template on top of the GHASH library. Remove "ghash" from the
crypto_shash API, as it's no longer needed

- Enable optimizations by default

- SM3

- Migrate the kernel's existing SM3 code into lib/crypto/, and
reimplement the traditional crypto API's "sm3" on top of it

- I don't recommend using SM3, but this cleanup is worthwhile
to organize the code the same way as other algorithms

- Testing improvements:

- Add a KUnit test suite for each of the new library APIs

- Migrate the existing ChaCha20Poly1305 test to KUnit

- Make the KUnit all_tests.config enable all crypto library tests

- Move the test kconfig options to the Runtime Testing menu

- Other updates to arch-optimized crypto code:

- Optimize SHA-256 for Zhaoxin CPUs using the Padlock Hash Engine

- Remove some MD5 implementations that are no longer worth keeping

- Drop big endian and voluntary preemption support from the arm64
code, as those configurations are no longer supported on arm64

- Make jitterentropy and samples/tsm-mr use the crypto library APIs

Merge tag 'rust-7.1' of git://git.kernel.org/pub/scm/linux/kernel/git/ojeda/linux

Pull Rust updates from Miguel Ojeda:
"Toolchain and infrastructure:

- Bump the minimum Rust version to 1.85.0 (and 'bindgen' to 0.71.1).

As proposed in LPC 2025 and the Maintainers Summit [1], we are
going to follow Debian Stable's Rust versions as our minimum
versions.

Debian Trixie was released on 2025-08-09 with a Rust 1.85.0 and
'bindgen' 0.71.1 toolchain, which is a fair amount of time for e.g.
kernel developers to upgrade.

Other major distributions support a Rust version that is high
enough as well, including:

+ Arch Linux.
+ Fedora Linux.
+ Gentoo Linux.
+ Nix.
+ openSUSE Slowroll and openSUSE Tumbleweed.
+ Ubuntu 25.10 and 26.04 LTS. In addition, 24.04 LTS using
their versioned packages.

The merged patch series comes with the associated cleanups and
simplifications treewide that can be performed thanks to both
bumps, as well as documentation updates.

In addition, start using 'bindgen''s '--with-attribute-custom-enum'
feature to set the 'cfi_encoding' attribute for the 'lru_status'
enum used in Binder.

Link: https://lwn.net/Articles/1050174/ [1]

- Add experimental Kconfig option ('CONFIG_RUST_INLINE_HELPERS') that
inlines C helpers into Rust.

Essentially, it performs a step similar to LTO, but just for the
helpers, i.e. very local and fast.

It relies on 'llvm-link' and its '--internalize' flag, and requires
a compatible LLVM between Clang and 'rustc' (i.e. same major
version, 'CONFIG_RUSTC_CLANG_LLVM_COMPATIBLE'). It is only enabled
for two architectures for now.

The result is a measurable speedup in different workloads that
different users have tested. For instance, for the null block
driver, it amounts to a 2%.

- Support global per-version flags.

While we already have per-version flags in many places, we didn't
have a place to set global ones that depend on the compiler
version, i.e. in 'rust_common_flags', which sometimes is needed to
e.g. tweak the lints set per version.

Use that to allow the 'clippy::precedence' lint for Rust < 1.86.0,
since it had a change in behavior.

- Support overriding the crate name and apply it to Rust Binder,
which wanted the module to be called 'rust_binder'.

- Add the remaining '__rust_helper' annotations (started in the
previous cycle).

'kernel' crate:

- Introduce the 'const_assert!' macro: a more powerful version of
'static_assert!' that can refer to generics inside functions or
implementation bodies, e.g.:

fn f<const N: usize>() {
const_assert!(N > 1);
}

fn g<T>() {
const_assert!(size_of::<T>() > 0, "T cannot be ZST");
}

In addition, reorganize our set of build-time assertion macros
('{build,const,static_assert}!') to live in the 'build_assert'
module.

Finally, improve the docs as well to clarify how these are
different from one another and how to pick the right one to use,
and their equivalence (if any) to the existing C ones for extra
clarity.

- 'sizes' module: add 'SizeConstants' trait.

This gives us typed 'SZ_*' constants (avoiding casts) for use in
device address spaces where the address width depends on the
hardware (e.g. 32-bit MMIO windows, 64-bit GPU framebuffers, etc.),
e.g.:

let gpu_heap = 14 * u64::SZ_1M;
let mmio_window = u32::SZ_16M;

- 'clk' module: implement 'Send' and 'Sync' for 'Clk' and thus
simplify the users in Tyr and PWM.

- 'ptr' module: add 'const_align_up'.

- 'str' module: improve the documentation of the 'c_str!' macro to
explain that one should only use it for non-literal cases (for the
other case we instead use C string literals, e.g. 'c"abc"').

- Disallow the use of 'CStr::{as_ptr,from_ptr}' and clean one such
use in the 'task' module.

- 'sync' module: finish the move of 'ARef' and 'AlwaysRefCounted'
outside of the 'types' module, i.e. update the last remaining
instances and finally remove the re-exports.

- 'error' module: clarify that 'from_err_ptr' can return 'Ok(NULL)',
including runtime-tested examples.

The intention is to hopefully prevent UB that assumes the result of
the function is not 'NULL' if successful. This originated from a
case of UB I noticed in 'regulator' that created a 'NonNull' on it.

Timekeeping:

- Expand the example section in the 'HrTimer' documentation.

- Mark the 'ClockSource' trait as unsafe to ensure valid values for
'ktime_get()'.

- Add 'Delta::from_nanos()'.

'pin-init' crate:

- Replace the 'Zeroable' impls for 'Option<NonZero*>' with impls of
'ZeroableOption' for 'NonZero*'.

- Improve feature gate handling for unstable features.

- Declutter the documentation of implementations of 'Zeroable' for
tuples.

- Replace uses of 'addr_of[_mut]!' with '&raw [mut]'.

rust-analyzer:

- Add type annotations to 'generate_rust_analyzer.py'.

- Add support for scripts written in Rust ('generate_rust_target.rs',
'rustdoc_test_builder.rs', 'rustdoc_test_gen.rs').

- Refactor 'generate_rust_analyzer.py' to explicitly identify host
and target crates, improve readability, and reduce duplication.

And some other fixes, cleanups and improvements"

power: reset: Add QEMU virt-ctrl driver

Add a new driver for the 'virt-ctrl' device found on QEMU virt machines
(e.g. m68k). This device provides a simple interface for system reset
and power off [1].

This driver utilizes the modern system-off API to register callbacks
for both system restart and power off. It also registers a reboot
notifier to catch SYS_HALT events, ensuring that LINUX_REBOOT_CMD_HALT
is properly handled. It is designed to be generic and can be reused by
other architectures utilizing this QEMU device.

====================
Add support for PIC64-HPSC/HX MDIO controller

This series adds a driver for the two MDIO controllers of PIC64-HPSC/HX.
The hardware supports C22 and C45 but only C22 is implemented for now.

This MDIO hardware is based on a Microsemi design supported in Linux by
mdio-mscc-miim.c. However, The register interface is completely different
with pic64hpsc, hence the need for a separate driver.

The documentation recommends an input clock of 156.25MHz and a prescaler of
39, which yields an MDIO clock of 1.95MHz.

This was tested on Microchip HB1301 evalkit which has a VSC8574 and a
VSC8541. I've tested with bus frequencies of 0.6, 1.95 and 2.5 MHz.

This series also adds a PHY write barrier when disabling PHY interrupts as
discussed in: https://lore.kernel.org/acvUqDgepCIScs8M@shell.armlinux.org.uk
