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)

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()

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)"

ACPI: driver: Do not set acpi_device_class() unnecessarily

Several core ACPI device drivers set acpi_device_class() for the given
struct acpi_device to whatever they like, but that value is never used
unless the driver itself uses it and, sadly, they neglect to clear it on
remove. Since the only one of them still using acpi_device_class()
after previous changes is the button driver, update the others to stop
setting it in vain. Also drop the related device class sybmols that
become redundant.

Since the ACPI button driver continues to use acpi_device_class(), make
it clear the struct field represented by acpi_device_class() in its
remove callback.

ACPI: driver: Do not set acpi_device_name() unnecessarily

ACPI drivers usually set acpi_device_name() for the given struct
acpi_device to whatever they like, but that value is never used unless
the driver itself uses it and, quite unfortunately, drivers neglect to
clear it on remove. Some drivers use it for printing messages or
initializing the names of subordinate devices, but it is better to use
string literals for that, especially if the given one is used just once.

To eliminate unnecessary overhead related to acpi_device_name()
handling, rework multiple core ACPI device drivers to stop setting
acpi_device_name() for struct acpi_device objects manipulated
by them and use a string literal instead of it where applicable.

No intentional functional impact.

Merge tag 'acpi-6.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull ACPI updates from Rafael Wysocki:
"This one is significantly larger than previous ACPI support pull
requests because several significant updates have coincided in it.

First, there is a routine ACPICA code update, to upstream version
20251212, but this time it covers new ACPI 6.6 material that has not
been covered yet. Among other things, it includes definitions of a few
new ACPI tables and updates of some others, like the GICv5 MADT
structures and ARM IORT IWB node definitions that are used for adding
GICv5 ACPI probing on ARM (that technically is IRQ subsystem material,
but it depends on the ACPICA changes, so it is included here). The
latter alone adds a few hundred lines of new code.

Second, there is an update of ACPI _OSC handling including a fix that
prevents failures from occurring in some corner cases due to careless
handling of _OSC error bits.

On top of that, the "system resource" ACPI device objects with the
PNP0C01 and PNP0C02 are now going to be handled by the ACPI core
device enumeration code instead of handing them over to the legacy PNP
system driver which causes device enumeration issues to occur. Some of
those issues have been worked around in device drivers and elsewhere
and those workarounds should not be necessary any more, so they are
going away.

Moreover, the time has come to convert all "core ACPI" device drivers
that were still using struct acpi_driver objects for device binding
into proper platform drivers that use struct platform_driver for this
purpose. These updates are accompanied by some requisite core ACPI
device enumeration code changes.

Next, there are ACPI APEI updates, including changes to avoid excess
overhead in the NMI handler and in SEA on the ARM side, changes to
unify ACPI-based HW error tracing and logging, and changes to prevent
APEI code from reaching out of its allocated memory.

There are also some ACPI power management updates, mostly related to
the ACPI cpuidle support in the processor driver, suspend-to-idle
handling on systems with ACPI support and to ACPI PM of devices.

In addition to the above, bugs are fixed and the code is cleaned up in
assorted places all over.

Specifics:

- Update the ACPICA code in the kernel to upstream version 20251212
which includes the following changes:
* Add support for new ACPI table DTPR (Michal Camacho Romero)
* Release objects with acpi_ut_delete_object_desc() (Zilin Guan)
* Add UUIDs for Microsoft fan extensions and UUIDs associated with
TPM 2.0 devices (Armin Wolf)
* Fix NULL pointer dereference in acpi_ev_address_space_dispatch()
(Alexey Simakov)
* Add KEYP ACPI table definition (Dave Jiang)
* Add support for the Microsoft display mux _OSI string (Armin
Wolf)
* Add definitions for the IOVT ACPI table (Xianglai Li)
* Abort AML bytecode execution on AML_FATAL_OP (Armin Wolf)
* Include all fields in subtable type1 for PPTT (Ben Horgan)
* Add GICv5 MADT structures and Arm IORT IWB node definitions
(Jose Marinho)
* Update Parameter Block structure for RAS2 and add a new flag in
Memory Affinity Structure for SRAT (Pawel Chmielewski)
* Add _VDM (Voltage Domain) object (Pawel Chmielewski)

- Add support for GICv5 ACPI probing on ARM which is based on the
GICv5 MADT structures and ARM IORT IWB node definitions recently
added to ACPICA (Lorenzo Pieralisi)

- Rework ACPI PM notification setup for PCI root buses and modify the
ACPI PM setup for devices to register wakeup source objects under
physical (that is, PCI, platform, etc.) devices instead of doing
that under their ACPI companions (Rafael Wysocki)

- Adjust debug messages regarding postponed ACPI PM printed during
system resume to be more accurate (Rafael Wysocki)

- Remove dead code from lps0_device_attach() (Gergo Koteles)

- Start to invoke Microsoft Function 9 (Turn On Display) of the Low-
Power S0 Idle (LPS0) _DSM in the suspend-to-idle resume flow on
systems with ACPI LPS0 support to address a functional issue on
Lenovo Yoga Slim 7i Aura (15ILL9), where system fans and keyboard
backlights fail to resume after suspend (Jakob Riemenschneider)

- Add sysfs attribute cid for exposing _CID lists under ACPI device
objects (Rafael Wysocki)

- Replace sprintf() with sysfs_emit() in all of the core ACPI sysfs
interface code (Sumeet Pawnikar)

- Use acpi_get_local_u64_address() in the code implementing ACPI
support for PCI to evaluate _ADR instead of evaluating that object
directly (Andy Shevchenko)

- Add JWIPC JVC9100 to irq1_level_low_skip_override[] to unbreak
serial IRQs on that system (Ai Chao)

- Fix handling of _OSC errors in acpi_run_osc() to avoid failures on
systems where _OSC error bits are set even though the _OSC return
buffer contains acknowledged feature bits (Rafael Wysocki)

- Clean up and rearrange \_SB._OSC handling for general platform
features and USB4 features to avoid code duplication and
unnecessary memory management overhead (Rafael Wysocki)

- Make the ACPI core device enumeration code handle PNP0C01 and
PNP0C02 ("system resource") device objects directly instead of
letting the legacy PNP system driver handle them to avoid device
enumeration issues on systems where PNP0C02 is present in the _CID
list under ACPI device objects with a _HID matching a proper device
driver in Linux (Rafael Wysocki)

- Drop workarounds for the known device enumeration issues related to
_CID lists containing PNP0C02 (Rafael Wysocki)

- Drop outdated comment regarding removed function in the ACPI-based
device enumeration code (Julia Lawall)

- Make PRP0001 device matching work as expected for ACPI device
objects using it as a _HID for board development and similar
purposes (Kartik Rajput)

- Use async schedule function in acpi_scan_clear_dep_fn() to avoid
races with user space initialization on some systems (Yicong Yang)

- Add a piece of documentation explaining why binding drivers
directly to ACPI device objects is not a good idea in general and
why it is desirable to convert drivers doing so into proper
platform drivers that use struct platform_driver for device binding
(Rafael Wysocki)

- Convert multiple "core ACPI" drivers, including the NFIT ACPI
device driver, the generic ACPI button drivers, the generic ACPI
thermal zone driver, the ACPI hardware event device (HED) driver,
the ACPI EC driver, the ACPI SMBUS HC driver, the ACPI Smart
Battery Subsystem (SBS) driver, and the ACPI backlight (video)
driver to proper platform drivers that use struct platform_driver
for device binding (Rafael Wysocki)

- Use acpi_get_local_u64_address() in the ACPI backlight (video)
driver to evaluate _ADR instead of evaluating that object directly
(Andy Shevchenko)

- Convert the generic ACPI battery driver to a proper platform driver
using struct platform_driver for device binding (Rafael Wysocki)

- Fix incorrect charging status when current is zero in the generic
ACPI battery driver (Ata İlhan Köktürk)

- Use LIST_HEAD() for initializing a stack-allocated list in the
generic ACPI watchdog device driver (Can Peng)

- Rework the ACPI idle driver initialization to register it directly
from the common initialization code instead of doing that from a
CPU hotplug "online" callback and clean it up (Huisong Li, Rafael
Wysocki)

- Fix a possible NULL pointer dereference in
acpi_processor_errata_piix4() (Tuo Li)

- Make read-only array non_mmio_desc[] static const (Colin Ian King)

- Prevent the APEI GHES support code on ARM from accessing memory out
of bounds or going past the ARM processor CPER record buffer (Mauro
Carvalho Chehab)

- Prevent cper_print_fw_err() from dumping the entire memory on
systems with defective firmware (Mauro Carvalho Chehab)

- Improve ghes_notify_nmi() status check to avoid unnecessary
overhead in the NMI handler by carrying out all of the requisite
preparations and the NMI registration time (Tony Luck)

- Refactor the GHES driver by extracting common functionality into
reusable helper functions to reduce code duplication and improve
the ghes_notify_sea() status check in analogy with the previous
ghes_notify_nmi() status check improvement (Shuai Xue)

- Make ELOG and GHES log and trace consistently and support the CPER
CXL protocol analogously (Fabio De Francesco)

- Disable KASAN instrumentation in the APEI GHES driver when compile
testing with clang < 18 (Nathan Chancellor)

- Let ghes_edac be the preferred driver to load on __ZX__ and _BYO_
systems by extending the platform detection list in the APEI GHES

ACPI: processor: Remove unused empty stubs of some functions

Empty stubs are defined in processor.h for some functions provided by
the ACPI processor idle driver, but those functions are only used in
the main ACPI processor driver which requires the ACPI processor idle
driver to be present (selecting CONFIG_ACPI_PROCESSOR causes
CONFIG_ACPI_PROCESSOR_IDLE to be selected too automatically).

This means that the empty stubs in question are not really necessary and
if both CONFIG_ACPI_PROCESSOR and CONFIG_ACPI_PROCESSOR_IDLE are unset,
the compiler complains that they are defined, but not used. Drop them
to get rid of the compiler warning.

ACPI: processor: idle: Optimize ACPI idle driver registration

Currently, the ACPI idle driver is registered from within a CPU
hotplug callback. Although this didn't cause any functional issues,
this is questionable and confusing. And it is better to register
the cpuidle driver when all of the CPUs have been brought up.

So add a new function to initialize acpi_idle_driver based on the
power management information of an available CPU and register cpuidle
driver in acpi_processor_driver_init().

This commit has four changes under the commit 7a8c994cbb2d (ACPI:
processor: idle: Optimize ACPI idle driver registration):

1) move acpi_processor_register_idle_driver() ahead of the
driver_register().
2) add acpi_processor_cstate_first_run_checks() before calling
