Merge tag 'acpi-6.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull ACPI updates from Rafael Wysocki: "These include new ACPICA material, a rework of the ACPI thermal driver, a switch-over of the ACPI processor driver to using _OSC instead of (long deprecated) _PDC for CPU initialization, a rework of firmware notifications handling in several drivers, fixes and cleanups for suspend-to-idle handling on AMD systems, ACPI backlight driver updates and more. Specifics: - Update the ACPICA code in the kernel to upstream revision 20230628 including the following changes: - Suppress a GCC 12 dangling-pointer warning (Philip Prindeville) - Reformat the ACPI_STATE_COMMON macro and its users (George Guo) - Replace the ternary operator with ACPI_MIN() (Jiangshan Yi) - Add support for _DSC as per ACPI 6.5 (Saket Dumbre) - Remove a duplicate macro from zephyr header (Najumon B.A) - Add data structures for GED and _EVT tracking (Jose Marinho) - Fix misspelled CDAT DSMAS define (Dave Jiang) - Simplify an error message in acpi_ds_result_push() (Christophe Jaillet) - Add a struct size macro related to SRAT (Dave Jiang) - Add AML_NO_OPERAND_RESOLVE flag to Timer (Abhishek Mainkar) - Add support for RISC-V external interrupt controllers in MADT (Sunil V L) - Add RHCT flags, CMO and MMU nodes (Sunil V L) - Change ACPICA version to 20230628 (Bob Moore) - Introduce new wrappers for ACPICA notify handler install/remove and convert multiple drivers to using their own Notify() handlers instead of the ACPI bus type .notify() slated for removal (Michal Wilczynski) - Add backlight=native DMI quirk for Apple iMac12,1 and iMac12,2 (Hans de Goede) - Put ACPI video and its child devices explicitly into D0 on boot to avoid platform firmware confusion (Kai-Heng Feng) - Add backlight=native DMI quirk for Lenovo Ideapad Z470 (Jiri Slaby) - Support obtaining physical CPU ID from MADT on LoongArch (Bibo Mao) - Convert ACPI CPU initialization to using _OSC instead of _PDC that has been depreceted since 2018 and dropped from the specification in ACPI 6.5 (Michal Wilczynski, Rafael Wysocki) - Drop non-functional nocrt parameter from ACPI thermal (Mario Limonciello) - Clean up the ACPI thermal driver, rework the handling of firmware notifications in it and make it provide a table of generic trip point structures to the core during initialization (Rafael Wysocki) - Defer enumeration of devices with _DEP pointing to IVSC (Wentong Wu) - Install SystemCMOS address space handler for ACPI000E (TAD) to meet platform firmware expectations on some platforms (Zhang Rui) - Fix finding the generic error data in the ACPi extlog driver for compatibility with old and new firmware interface versions (Xiaochun Lee) - Remove assorted unused declarations of functions (Yue Haibing) - Move AMBA bus scan handling into arm64 specific directory (Sudeep Holla) - Fix and clean up suspend-to-idle interface for AMD systems (Mario Limonciello, Andy Shevchenko) - Fix string truncation warning in pnpacpi_add_device() (Sunil V L)" * tag 'acpi-6.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (66 commits) ACPI: x86: s2idle: Add a function to get LPS0 constraint for a device ACPI: x86: s2idle: Add for_each_lpi_constraint() helper ACPI: x86: s2idle: Add more debugging for AMD constraints parsing ACPI: x86: s2idle: Fix a logic error parsing AMD constraints table ACPI: x86: s2idle: Catch multiple ACPI_TYPE_PACKAGE objects ACPI: x86: s2idle: Post-increment variables when getting constraints ACPI: Adjust #ifdef for *_lps0_dev use ACPI: TAD: Install SystemCMOS address space handler for ACPI000E ACPI: Remove assorted unused declarations of functions ACPI: extlog: Fix finding the generic error data for v3 structure PNP: ACPI: Fix string truncation warning ACPI: Remove unused extern declaration acpi_paddr_to_node() ACPI: video: Add backlight=native DMI quirk for Apple iMac12,1 and iMac12,2 ACPI: video: Put ACPI video and its child devices into D0 on boot ACPI: processor: LoongArch: Get physical ID from MADT ACPI: scan: Defer enumeration of devices with a _DEP pointing to IVSC device ACPI: thermal: Eliminate code duplication from acpi_thermal_notify() ACPI: thermal: Drop unnecessary thermal zone callbacks ACPI: thermal: Rework thermal_get_trend() ACPI: thermal: Use trip point table to register thermal zones ...
