Pull ACPI updates from Rafael Wysocki:
"These update the ACPICA code in the kernel to upstream version
20240827, add support for ACPI-based enumeration of interrupt
controllers on RISC-V along with some related irqchip updates, clean
up the ACPI device object sysfs interface, add some quirks for
backlight handling and IRQ overrides, fix assorted issues and clean up
code.
Specifics:
- Check return value in acpi_db_convert_to_package() (Pei Xiao)
- Detect FACS and allow setting the waking vector on reduced-hardware
ACPI platforms (Jiaqing Zhao)
- Allow ACPICA to represent semaphores as integers (Adrien Destugues)
- Complete CXL 3.0 CXIMS structures support in ACPICA (Zhang Rui)
- Make ACPICA support SPCR version 4 and add RISC-V SBI Subtype to
DBG2 (Sia Jee Heng)
- Implement the Dword_PCC Resource Descriptor Macro in ACPICA (Jose
Marinho)
- Correct the typo in struct acpi_mpam_msc_node member (Punit
Agrawal)
- Implement ACPI_WARNING_ONCE() and ACPI_ERROR_ONCE() and use them to
prevent a Stall() violation warning from being printed every time
this takes place (Vasily Khoruzhick)
- Allow PCC Data Type in MCTP resource (Adam Young)
- Fix memory leaks on acpi_ps_get_next_namepath() and
acpi_ps_get_next_field() failures (Armin Wolf)
- Add support for supressing leading zeros in hex strings when
converting them to integers and update integer-to-hex-string
conversions in ACPICA (Armin Wolf)
- Add support for Windows 11 22H2 _OSI string (Armin Wolf)
- Avoid warning for Dump Functions in ACPICA (Adam Lackorzynski)
- Add extended linear address mode to HMAT MSCIS in ACPICA (Dave
Jiang)
- Handle empty connection_node in iasl (Aleksandrs Vinarskis)
- Allow for more flexibility in _DSM args (Saket Dumbre)
- Setup for ACPICA release 20240827 (Saket Dumbre)
- Add ACPI device enumeration support for interrupt controller
probing including taking dependencies into account (Sunil V L)
- Implement ACPI-based interrupt controller probing on RISC-V
(Sunil V L)
- Add ACPI support for AIA in riscv-intc and add ACPI support to
riscv-imsic, riscv-aplic, and sifive-plic (Sunil V L)
- Do not release locks during operation region accesses in the ACPI
EC driver (Rafael Wysocki)
- Fix up the _STR handling in the ACPI device object sysfs interface,
make it represent the device object attributes as an attribute
group and make it rely on driver core functionality for sysfs
attrubute management (Thomas Weißschuh)
- Extend error messages printed to the kernel log when
acpi_evaluate_dsm() fails to include revision and function number
(David Wang)
- Add a new AMDI0015 platform device ID to the ACPi APD driver for
AMD SoCs (Shyam Sundar S K)
- Use the driver core for the async probing management in the ACPI
battery driver (Thomas Weißschuh)
- Remove redundant initalizations of a local variable to NULL from
the ACPI battery driver (Ilpo Järvinen)
- Remove unneeded check in tps68470_pmic_opregion_probe() (Aleksandr
Mishin)
- Add support for setting the EPP register through the ACPI CPPC
sysfs interface if it is in FFH (Mario Limonciello)
- Fix MASK_VAL() usage in the ACPI CPPC library (Clément Léger)
- Reduce the log level of a per-CPU message about idle states in the
ACPI processor driver (Li RongQing)

device (PAD) driver (Seiji Nishikawa)
- Add force_vendor quirk for Panasonic Toughbook CF-18 in the ACPI
backlight driver (Hans de Goede)
- Make the DMI checks related to backlight handling on Lenovo Yoga
Tab 3 X90F less strict (Hans de Goede)
- Enforce native backlight handling on Apple MacbookPro9,2 (Esther
Shimanovich)
- Add IRQ override quirks for Asus Vivobook Go E1404GAB and MECHREV
GM7XG0M, and refine the TongFang GMxXGxx quirk (Li Chen, Tamim
Khan, Werner Sembach)
- Quirk ASUS ROG M16 to default to S3 sleep (Luke D. Jones)
- Define and use symbols for device and class name lengths in the
ACPI bus type code and make the code use strscpy() instead of
strcpy() in several places (Muhammad Qasim Abdul Majeed)"
