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)"
