The inspur_platform_profile driver and the xiaomi-wmi driver both
meet the requirements for modern WMI drivers, as they both do not
use the legacy GUID-based interface and can be safely instantiated
multiple times.
Mark them both as legacy-free using the no_singleton flag.
Compile-tested only.

ACER Vivobook Flip (TP401NAS) virtual intel switch is implemented as
follow:
Device (VGBI)
{
Name (_HID, EisaId ("INT33D6") ...
Name (VBDS, Zero)
Method (_STA, 0, Serialized) // _STA: Status ...
Method (VBDL, 0, Serialized)
{
PB1E |= 0x20
VBDS |= 0x40
}
Method (VGBS, 0, Serialized)
{
Return (VBDS) /* \_SB_.PCI0.SBRG.EC0_.VGBI.VBDS */
}
...
}
By default VBDS is set to 0. At boot it is set to clamshell (bit 6 set)
only after method VBDL is executed.
Since VBDL is now evaluated in the probe routine later, after the device
is registered, the retrieved value of VBDS was still 0 ("tablet mode")
when setting up the virtual switch.
Make sure to evaluate VGBS after VBDL, to ensure the
convertible boots in clamshell mode, the expected default.

devm_device_add_groups() is being removed from the kernel, so move the

when the device is removed the driver core will properly clean up and
remove the groups, and the memory used by the attribute groups will be
freed because it was created with dev_* calls, so this is functionally
identical overall.

Acer Aspire 1 is a Snapdragon 7c based laptop. It uses an embedded
controller to perform a set of various functions, such as:
- Battery and charger monitoring;
- Keyboard layout control (i.e. fn_lock settings);
- USB Type-C DP alt mode HPD notifications;
- Laptop lid status.
Unfortunately, while all this functionality is implemented in ACPI, it's
currently not possible to use ACPI to boot Linux on such Qualcomm
devices. To allow Linux to still support the features provided by EC,
this driver reimplments the relevant ACPI parts. This allows us to boot
the laptop with Device Tree and retain all the features.

Some ARM64 based laptops and computers require vendor/board specific
drivers for their embedded controllers. Even though usually the most
important functionality of those devices is implemented inside ACPI,
unfortunately Linux doesn't currently have great support for ACPI on
platforms like Qualcomm Snapdragon that are used in most ARM64 laptops
today. Instead Linux relies on Device Tree for Qualcomm based devices
and it's significantly easier to reimplement the EC functionality in
a dedicated driver than to make use of ACPI code.
This commit introduces a new platform/arm64 subdirectory to give a
place to such drivers for EC-like devices.
A new MAINTAINERS entry is added for this directory. Patches to files in
this directory will be taken up by the platform-drivers-x86 team (i.e.
Hans de Goede and Ilpo Järvinen) with additional review from Bryan
O'Donoghue to represent ARM64 maintainers.

Pull thermal control updates from Rafael Wysocki:
"These mostly change the thermal core in a few ways allowing thermal
drivers to be simplified, in particular in their removal and failing
probe handling parts that are notoriously prone to errors, and
propagate the changes to several drivers.
Apart from that, support for a new platform is added (Intel Lunar
Lake-M), some bugs are fixed and some code is cleaned up, as usual.
Specifics:
- Store zone trips table and zone operations directly in struct
thermal_zone_device (Rafael Wysocki)
- Fix up flex array initialization during thermal zone device
registration (Nathan Chancellor)
- Rework writable trip points handling in the thermal core and
several drivers (Rafael Wysocki)
- Thermal core code cleanups (Dan Carpenter, Flavio Suligoi)
- Use thermal zone accessor functions in the int340x Intel thermal
driver (Rafael Wysocki)
- Add Lunar Lake-M PCI ID to the int340x Intel thermal driver

- Minor fixes for thermal governors (Rafael Wysocki, Di Shen)
- Trip point handling fixes for the iwlwifi wireless driver (Rafael

This release sees some exciting changes from David Lechner which
implements some optimisations that have been talked about for a long
time which allows client drivers to pre-prepare SPI messages for
repeated or low latency use. This lets us move work out of latency
sensitive paths and avoid repeating work for frequently performed
operations. As well as being useful in itself this will also be used in
future to allow controllers to directly trigger SPI operations (eg, from
interrupts).
Otherwise this release has mostly been focused on cleanups, plus a
couple of new devices:
- Support for pre-optimising messages.
- A big set of updates from Uwe Kleine-König moving drivers to use APIs
with more modern terminology for controllers.
- Major overhaul of the s3c64xx driver.
- Support for Google GS101 and Samsung Exynos850.

The current code only prints PKGC-10 residency when the PKGC-10
is not reached in previous 'freeze' attempt. To debug PKGC-10 issues, we
also need to know other PKGC residency counters to better triage issues.
Ex:
1. When system is stuck in PC2, it can be caused short LTR from device.
2. When system is stuck in PC8, it can be caused by display engine.
To better triage issues, all PKGC residency are needed when issues happen.
Example log:
CPU did not enter Package C10!!! (Package C10 cnt=0x0)
Prev Package C2 cnt = 0x2191a325de, Current Package C2 cnt = 0x21aba30724
Prev Package C3 cnt = 0x0, Current Package C3 cnt = 0x0
Prev Package C6 cnt = 0x0, Current Package C6 cnt = 0x0
Prev Package C7 cnt = 0x0, Current Package C7 cnt = 0x0
Prev Package C8 cnt = 0x0, Current Package C8 cnt = 0x0
Prev Package C9 cnt = 0x0, Current Package C9 cnt = 0x0
Prev Package C10 cnt = 0x0, Current Package C10 cnt = 0x0
With this log, we can know whether it's a stuck PC2 issue, and we can
check whether the short LTR from device causes the issue.

AAEON PICO-TGU4 board doesn't have any LED but there are bogus LED

The reason is that the ~0 read from asus_wmi_get_devstate() is treated

So filter out ~0 read to prevent bogus LED controls being created.

For family 1AH, certain PMF features have been enhanced - leading to a
newer APMF (AMD PMF) spec (BIOS and PMF driver interface) called v2.
This information would be fed into the if_version field of the
verify_interface method of the APMF call from the BIOS.
Use this information to store the version number to differentiate
between v1 or v2 and also store the information into the PMF private
data structure, as this information would be required for further code
branching to support the latest silicon.

For the Bay Trail or Cherry Trail SoC to enter the S0i3 power-level
at s2idle suspend requires most of the hw-blocks / devices in the SoC
to be in D3 when entering s2idle suspend.
If some devices are not in D3 then the SoC will stay in a higher
power state, consuming much more power from the battery then in S0i3.
Use the new acpi_s2idle_dev_ops and acpi_register_lps0_dev()
functionality to register a new s2idle check function which checks that
all hardware blocks in the South complex (controlled by the PMC)
are in a state that allows the SoC to enter S0i3 and prints an error
message for any device in D0.
Some blocks are not used on lower-featured versions of the SoC and
these blocks will always report being in D0 on SoCs were they are
not used. A false-positive mask is used to identify these blocks
and for blocks in this mask the error is turned into a debug message
to avoid false-positive error messages.
Note the pmc_atom code is enabled by CONFIG_X86_INTEL_LPSS which
already depends on ACPI.

When HWP (Hardware P-states) is disabled, dynamic SST features are
disabled. But user should still be able to read the current core-power

To address this, do not call disable_dynamic_sst_features() when the

The whitelist-based approach for preventing older WMI drivers from
being instantiated multiple times has many drawbacks:
- uses cannot see all available WMI devices (if not whitelisted)
- whitelisting a WMI driver requires changes in the WMI driver core
- maintenance burden for driver and subsystem developers
Since the WMI driver core already takes care that older WMI drivers

Many older WMI drivers cannot be instantiated multiple times for
two reasons:
- they are using the legacy GUID-based WMI API
- they are singletons (with global state)
Prevent such WMI drivers from binding to WMI devices with a duplicated
GUID, as this would mean that the WMI driver will be instantiated at
least two times (one for the original GUID and one for the duplicated

WMI drivers which can be instantiated multiple times can signal this

The current implementation has a couple of shortcomings:
- It fails to handle hybrid systems correctly.
- The APIC registration code which handles CPU number assignents is in
the middle of the APIC code and detached from the topology evaluation.
- The various mechanisms which enumerate APICs, ACPI, MPPARSE and guest
specific ones, tweak global variables as they see fit or in case of
XENPV just hack around the generic mechanisms completely.
- The CPUID topology evaluation code is sprinkled all over the vendor
code and reevaluates global variables on every hotplug operation.
- There is no way to analyze topology on the boot CPU before bringing up
the APs. This causes problems for infrastructure like PERF which needs
to size certain aspects upfront or could be simplified if that would be
possible.
- The APIC admission and CPU number association logic is incomprehensible
and overly complex and needs to be kept around after boot instead of
completing this right after the APIC enumeration.
This update addresses these shortcomings with the following changes:
- Rework the CPUID evaluation code so it is common for all vendors and
provides information about the APIC ID segments in a uniform way
independent of the number of segments (Thread, Core, Module, ..., Die,
Package) so that this information can be computed instead of rewriting
global variables of dubious value over and over.
- A few cleanups and simplifcations of the APIC, IO/APIC and related
interfaces to prepare for the topology evaluation changes.
- Seperation of the parser stages so the early evaluation which tries to
find the APIC address can be seperately overridden from the late
evaluation which enumerates and registers the local APIC as further
preparation for sanitizing the topology evaluation.
- A new registration and admission logic which
- encapsulates the inner workings so that parsers and guest logic
cannot longer fiddle in it
- uses the APIC ID segments to build topology bitmaps at registration
time
- provides a sane admission logic
- allows to detect the crash kernel case, where CPU0 does not run on
the real BSP, automatically. This is required to prevent sending
INIT/SIPI sequences to the real BSP which would reset the whole
machine. This was so far handled by a tedious command line
parameter, which does not even work in nested crash scenarios.
- Associates CPU number after the enumeration completed and prevents
the late registration of APICs, which was somehow tolerated before.
- Converting all parsers and guest enumeration mechanisms over to the
new interfaces.
This allows to get rid of all global variable tweaking from the parsers
and enumeration mechanisms and sanitizes the XEN[PV] handling so it can
use CPUID evaluation for the first time.
- Mopping up existing sins by taking the information from the APIC ID
segment bitmaps.
This evaluates hybrid systems correctly on the boot CPU and allows for
cleanups and fixes in the related drivers, e.g. PERF.
The series has been extensively tested and the minimal late fallout due to
a broken ACPI/MADT table has been addressed by tightening the admission
logic further.

In drivers/platform/goldfish/Kconfig:
menuconfig GOLDFISH
bool "Platform support for Goldfish virtual devices"
depends on HAS_IOMEM && HAS_DMA
While Kconfig allows multiple entries, it generally leads to tricky

Prior to commit bd2f348db5 ("goldfish: refactor goldfish platform

After the mentioned commit added the second entry with a user prompt,

On Goldmont p2sb_bar() only ever gets called for 2 devices, the actual P2SB
devfn 13,0 and the SPI controller which is part of the P2SB, devfn 13,2.
But the current p2sb code tries to cache BAR0 info for all of
devfn 13,0 to 13,7 . This involves calling pci_scan_single_device()
for device 13 functions 0-7 and the hw does not seem to like
pci_scan_single_device() getting called for some of the other hidden
devices. E.g. on an ASUS VivoBook D540NV-GQ065T this leads to continuous
ACPI errors leading to high CPU usage.
Fix this by only caching BAR0 info and thus only calling
pci_scan_single_device() for the P2SB and the SPI controller.

Currently, the driver has two behaviors to deal with new & unsupported

1. For register and unknown block types, the driver will fail to load
with the following error message:
[ 4510.956369] mlxbf-pmc: probe of MLNXBFD2:00 failed with error -22
2. For counter and crspace blocks, the driver will load and sysfs files
will be created but getting the contents of event_list or trying to
setup the counter will fail
Instead, let's ignore and log unsupported blocks. This means the driver
will always load and unsupported blocks will never show up in sysfs.

The ACPI WMI specification states:
"The _WED control method is evaluated by the mapper in
response to receiving a notification from a control
method."
This means that _WED should be evaluated unconditionally even
if no WMI event consumers are present.
Some firmware implementations actually depend on this behavior
by storing the event data inside a queue which will fill up if
the WMI core stops retrieving event data items due to no
consumers being present
Fix this by always evaluating _WED even if no WMI event consumers
are present.

WMI event drivers which do not have no_notify_data set expect
that each WMI event contains valid data. Evaluating _WED however
might return no data, which can cause issues with such drivers.
Fix this by validating that evaluating _WED did return data.

If a WMI event driver has no_notify_data set, then it indicates
support for WMI events which provide no notify data, otherwise
the notify() callback expects a valid ACPI object as notify data.
However if a WMI event driver which requires notify data is bound
to a WMI event device which cannot retrieve such data due to the
_WED ACPI method being absent, then the driver will be dysfunctional
since all WMI events will be dropped due to the missing notify data.
Fix this by not allowing such WMI event drivers to bind to WMI event
devices which do not support retrieving of notify data. Also reword
the description of no_notify_data a bit.

Randomly a Lenovo Z13 will trigger a kernel warning traceback from this
condition:
```
if (WARN_ON((profile < 0) || (profile >= ARRAY_SIZE(profile_names))))
```
This happens because thinkpad-acpi always assumes that
convert_dytc_to_profile() successfully updated the profile. On the
contrary a condition can occur that when dytc_profile_refresh() is called
the profile doesn't get updated as there is a -EOPNOTSUPP branch.
Catch this situation and avoid updating the profile. Also log this into
dynamic debugging in case any other modes should be added in the future.

In some cases UART attached devices which require an in kernel driver,
e.g. UART attached Bluetooth HCIs are described in the ACPI tables
by an ACPI device with a broken or missing UartSerialBusV2() resource.
This causes the kernel to create a /dev/ttyS# char-device for the UART
instead of creating an in kernel serdev-controller + serdev-device pair
for the in kernel driver.
The quirk handling in acpi_quirk_skip_serdev_enumeration() makes the kernel
create a serdev-controller device for these UARTs instead of a /dev/ttyS#.
Instantiating the actual serdev-device to bind to is up to pdx86 code,
so far this was handled by the x86-android-tablets code. But since
commit b286f4e87e ("serial: core: Move tty and serdev to be children of
serial core port device") the serdev-controller device has moved in the
device hierarchy from (e.g.) /sys/devices/pci0000:00/8086228A:00/serial0 to
/sys/devices/pci0000:00/8086228A:00/8086228A:00:0/8086228A:00:0.0/serial0 .
This makes this a bit trickier to do and another driver is in the works
which will also need this functionality.
Add a new helper to get the serdev-controller device, so that the new
code for this can be shared.

After commit 4014ae236b ("platform/x86: x86-android-tablets: Stop using
gpiolib private APIs") the touchscreen in the keyboard half of
the Lenovo Yogabook1 X90 stopped working with the following error:
Goodix-TS i2c-goodix_ts: error -EBUSY: Failed to get irq GPIO
The problem is that when getting the IRQ for instantiated i2c_client-s
from a GPIO (rather then using an IRQ directly from the IOAPIC),
x86_acpi_irq_helper_get() now properly requests the GPIO, which disallows
other drivers from requesting it. Normally this is a good thing, but
the goodix touchscreen also uses the IRQ as an output during reset
to select which of its 2 possible I2C addresses should be used.
Add a new free_gpio flag to struct x86_acpi_irq_data to deal with this
and release the GPIO after getting the IRQ in this special case.

On some devices the ACPI name of the touchscreen is e.g. either
MSSL1680:00 or MSSL1680:01 depending on the BIOS version.
This happens for example on the "Chuwi Hi8 Air" tablet where the initial
commit's ts_data uses "MSSL1680:00" but the tablets from the github issue
and linux-hardware.org probe linked below both use "MSSL1680:01".
Replace the strcmp() match on ts_data->acpi_name with a strstarts()
check to allow using a partial match on just the ACPI HID of "MSSL1680"
and change the ts_data->acpi_name for the "Chuwi Hi8 Air" accordingly
to fix the touchscreen not working on models where it is "MSSL1680:01".
Note this drops the length check for I2C_NAME_SIZE. This never was
necessary since the ACPI names used are never more then 11 chars and
I2C_NAME_SIZE is 20 so the replaced strncmp() would always stop long
before reaching I2C_NAME_SIZE.

The ACPI-WMI specification declares in the section "ACPI Control Method
Naming Conventions and Functionality for Windows 2000 Instrumentation"
that a WMxx control method takes 3 arguments: instance, method id and
argument buffer. This is also the case even when the underlying WMI
method does not have any input arguments.
So if a WMI driver evaluates a WMI method without passing an input
buffer, ACPICA will log a warning complaining that the third argument
is missing.
Prevent this by checking that a input buffer was passed, and return
an error if this was not the case.

Add 8BAD to the list of boards which have thermal profile selection
available. This allows the CPU to draw more power than the default TDP
barrier defined by the 'balanced' thermal profile (around 50W), hence
allowing it to perform better without being throttled by the embedded
controller (around 130W).
We first need to set the HP_OMEN_EC_THERMAL_PROFILE_TIMER_OFFSET to zero.
This prevents the timer countdown from reaching zero, making the embedded
controller "force-switch" the system's thermal profile back to 'balanced'
automatically.
We also need to put a number of specific flags in
HP_OMEN_EC_THERMAL_PROFILE_FLAGS_OFFSET when we're switching to another
thermal profile:
- for 'performance', we need to set both HP_OMEN_EC_FLAGS_TURBO and
HP_OMEN_EC_FLAGS_NOTIMER;
- for 'balanced' and 'powersave', we clear out the register to notify
the system that we want to lower the TDP barrier as soon as possible.
The third flag defined in the hp_thermal_profile_omen_flags enum,
HP_OMEN_EC_FLAGS_JUSTSET, is present for completeness.
To prevent potential behaviour breakage with other Omen models, a
separate omen_timed_thermal_profile_boards array has been added to list
which boards expose this behaviour.
Performance benchmarking was done with the help of silver.urih.com and
Google Chrome 120.0.6099.129, on Gnome 45.2, with the 'performance'
thermal profile set:
| | Performance | Stress | TDP |
|------------------|-------------|------------|-------|
| with my patch | P84549 | S0.1891 | 131W |
| without my patch | P44084 | S0.1359 | 47W |
The TDP measurements were done with the help of the s-tui utility,
during the load.
There is still work to be done:
- tune the CPU and GPU fans to better cool down and enhance
performance at the right time; right now, it seems that the fans are
not properly reacting to thermal/performance events, which in turn
either causes thermal throttling OR makes the fans spin way too long,
even though the temperatures have lowered down
- expose the CPU and GPU fan curves to user-land so that they can be
controlled just like what the Omen Gaming Hub utility proposes to
its users;

This commit performs four things:
- fix up the GUID string inconsistency (lower case 'e') from the

- separate GUID macros from the embedded controller offset macros
- rename the description of the module to better represent what it
actually achieves as a whole
- add a space right before the '*' pointer qualifier to match the
other array declarations

The activation for Scan at Field (SAF) includes a parameter to make
microcode wait for both threads to join. It's preferable to perform an
entry rendezvous before the activation to ensure that they start the
`wrmsr` close enough to each other. In some cases it has been observed
that one of the threads might be just a bit late to arrive. An entry
rendezvous reduces the likelihood of these cases occurring.
Add an entry rendezvous to ensure the activation on both threads happen
close enough to each other.

ARRAY_BIST requires the test to be invoked only from one of the HT
siblings of a core. If the other sibling was in mwait(), that didn't
permit the test to complete and resulted in several retries before the
test could finish.
The exit rendezvous was introduced to keep the HT sibling busy until
the primary CPU completed the test to avoid those retries. What is
actually needed is to ensure that both the threads rendezvous *before*
the wrmsr to trigger the test to give good chance to complete the test.
The `stop_machine()` function returns only after all the CPUs complete
running the function, and provides an exit rendezvous implicitly.
In kernel/stop_machine.c::multi_cpu_stop(), every CPU in the mask
needs to complete reaching MULTI_STOP_RUN. When all CPUs complete, the
state machine moves to next state, i.e MULTI_STOP_EXIT. Thus the
underlying API stop_core_cpuslocked() already provides an exit
rendezvous.
Add the rendezvous earlier in order to ensure the wrmsr is triggered
after all CPUs reach the do_array_test(). Remove the exit rendezvous
since stop_core_cpuslocked() already guarantees that.

directly the return value of gnss_insert_raw(). gnss_insert_raw()

The initialization of variable n can also be deferred after the
sanity check on pointer n and the declaration of all the int variables
can be combined as a final code clear-up.

Starting from Linux 5.16 kernel, Tx timeout mechanism was added
in the virtio_net driver which prints the "Tx timeout" warning
message when a packet stays in Tx queue for too long. Below is an
example of the reported message:
"[494105.316739] virtio_net virtio1 tmfifo_net0: TX timeout on
queue: 0, sq: output.0, vq: 0×1, name: output.0, usecs since
last trans: 3079892256".
This issue could happen when external host driver which drains the
FIFO is restared, stopped or upgraded. To avoid such confusing
"Tx timeout" messages, this commit adds logic to drop the outstanding
Tx packet if it's not able to transmit in two seconds due to Tx FIFO
full, which can be considered as congestion or out-of-resource drop.
This commit also handles the special case that the packet is half-
transmitted into the Tx FIFO. In such case, the packet is discarded
with remaining length stored in vring->rem_padding. So paddings with
zeros can be sent out when Tx space is available to maintain the
integrity of the packet format. The padded packet will be dropped on
the receiving side.

p2sb_bar() unhides P2SB device to get resources from the device. It
guards the operation by locking pci_rescan_remove_lock so that parallel
rescans do not find the P2SB device. However, this lock causes deadlock
when PCI bus rescan is triggered by /sys/bus/pci/rescan. The rescan
locks pci_rescan_remove_lock and probes PCI devices. When PCI devices
call p2sb_bar() during probe, it locks pci_rescan_remove_lock again.
Hence the deadlock.
To avoid the deadlock, do not lock pci_rescan_remove_lock in p2sb_bar().
Instead, do the lock at fs_initcall. Introduce p2sb_cache_resources()
for fs_initcall which gets and caches the P2SB resources. At p2sb_bar(),
refer the cache and return to the caller.
Before operating the device at P2SB DEVFN for resource cache, check
that its device class is PCI_CLASS_MEMORY_OTHER 0x0580 that PCH
specifications define. This avoids unexpected operation to other devices
at the same DEVFN.

When booting a kernel with CONFIG_CFI_CLANG, there is a CFI failure when
accessing any of the values under
/sys/devices/system/cpu/intel_uncore_frequency/package_00_die_00:
$ cat /sys/devices/system/cpu/intel_uncore_frequency/package_00_die_00/max_freq_khz
fish: Job 1, 'cat /sys/devices/system/cpu/int…' terminated by signal SIGSEGV (Address boundary error)
$ sudo dmesg &| grep 'CFI failure'
[ 170.953925] CFI failure at kobj_attr_show+0x19/0x30 (target: show_max_freq_khz+0x0/0xc0 [intel_uncore_frequency_common]; expected type: 0xd34078c5
The sysfs callback functions such as show_domain_id() are written as if
they are going to be called by dev_attr_show() but as the above message
shows, they are instead called by kobj_attr_show(). kCFI checks that the
destination of an indirect jump has the exact same type as the prototype
of the function pointer it is called through and fails when they do not.
These callbacks are called through kobj_attr_show() because
uncore_root_kobj was initialized with kobject_create_and_add(), which
means uncore_root_kobj has a ->sysfs_ops of kobj_sysfs_ops from
kobject_create(), which uses kobj_attr_show() as its ->show() value.
The only reason there has not been a more noticeable problem until this
point is that 'struct kobj_attribute' and 'struct device_attribute' have
the same layout, so getting the callback from container_of() works the
same with either value.
Change all the callbacks and their uses to be compatible with
kobj_attr_show() and kobj_attr_store(), which resolves the kCFI failure
and allows the sysfs files to work properly.

When an legacy WMI event handler is removed, an WMI event could
have called the handler just before it was removed, meaning the
handler could still be running after wmi_remove_notify_handler()
returns.
Something similar could also happens when using the WMI bus, as
the WMI core might still call the notify() callback from an WMI
driver even if its remove() callback was just called.
Fix this by introducing a rw semaphore which ensures that the
event state of a WMI device does not change while the WMI core
is handling an event for it.

When wmi_install_notify_handler()/wmi_remove_notify_handler() are
unable to enable/disable the WMI device, they unconditionally return
an error to the caller.
When registering legacy WMI notify handlers, this means that the
callback remains registered despite wmi_install_notify_handler()
having returned an error.
When removing legacy WMI notify handlers, this means that the
callback is removed despite wmi_remove_notify_handler() having
returned an error.
Fix this by only warning when the WMI device could not be enabled.

Pull ACPI updates from Rafael Wysocki:
"From the new features standpoint, the most significant change here is
the addition of CSI-2 and MIPI DisCo for Imaging support to the ACPI
device enumeration code that will allow MIPI cameras to be enumerated
through the platform firmware on systems using ACPI.
Also significant is the switch-over to threaded interrupt handlers for
the ACPI SCI and the dedicated EC interrupt (on systems where the
former is not used) which essentially allows all ACPI code to run with
local interrupts enabled. That should improve responsiveness
significantly on systems where multiple GPEs are enabled and the
handling of one SCI involves many I/O address space accesses which
previously had to be carried out in one go with disabled interrupts on
the local CPU.
Apart from the above, the ACPI thermal zone driver will use the
Thermal fast Sampling Period (_TFP) object if available, which should
allow temperature changes to be followed more accurately on some
systems, the ACPI Notify () handlers can run on all CPUs (not just on
CPU0), which should generally speed up the processing of events
signaled through the ACPI SCI, and the ACPI power button driver will
trigger wakeup key events via the input subsystem (on systems where it
is a system wakeup device)
In addition to that, there are the usual bunch of fixes and cleanups.
Specifics:
- Add CSI-2 and DisCo for Imaging support to the ACPI device
enumeration code (Sakari Ailus, Rafael J. Wysocki)
- Adjust the cpufreq thermal reduction algorithm in the ACPI
processor driver for Tegra241 (Srikar Srimath Tirumala, Arnd
Bergmann)
- Make acpi_proc_quirk_mwait_check() x86-specific (Rafael J. Wysocki)
- Switch over ACPI to using a threaded interrupt handler for the SCI
(Rafael J. Wysocki)
- Allow ACPI Notify () handlers to run on all CPUs and clean up the
ACPI interface for deferred events processing (Rafael J. Wysocki)
- Switch over the ACPI EC driver to using a threaded handler for the
dedicated IRQ on systems without the EC GPE (Rafael J. Wysocki)
- Adjust code using ACPICA spinlocks and the ACPI EC driver spinlock
to keep local interrupts on (Rafael J. Wysocki)
- Adjust the USB4 _OSC handshake to correctly handle cases in which
certain types of OS control are denied by the platform (Mika
Westerberg)
- Correct and clean up the generic function for parsing ACPI
data-only tables with array structure (Yuntao Wang)
- Modify acpi_dev_uid_match() to support different types of its
second argument and adjust its users accordingly (Raag Jadav)

Now that the driver core can properly handle constant struct bus_type,
move the ssam_bus_type variable to be a constant structure as well,
placing it into read-only memory which can not be modified at runtime.
It's also never used outside of
drivers/platform/surface/aggregator/bus.c so make it static and don't
export it as no one is using it.
