Merge tag 'acpi-6.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull ACPI updates from Rafael Wysocki:
 "ACPI and PNP updates for 6.1-rc1.

  These rearrange the ACPI device object initialization code (to get rid
  of a redundant parent pointer from struct acpi_device among other
  things), unify the _UID handling, drop support for some _OSI strings
  that should not be necessary any more, add new IDs to support more
  hardware and some more quirks, fix a few issues and clean up code all
  over.

  Specifics:

   - Reimplement acpi_get_pci_dev() using the list of physical devices
     associated with the given ACPI device object (Rafael Wysocki)

   - Rename ACPI device object reference counting functions (Rafael
     Wysocki)

   - Rearrange ACPI device object initialization code (Rafael Wysocki)

   - Drop parent field from struct acpi_device (Rafael Wysocki)

   - Extend the the int3472-tps68470 driver to support multiple
     consumers of a single TPS68470 along with the requisite
     framework-level support (Daniel Scally)

   - Filter out non-memory resources in is_memory(), add a helper
     function to find all memory type resources of an ACPI device object
     and use that function in 3 places (Heikki Krogerus)

   - Add IRQ override quirks for Asus Vivobook K3402ZA/K3502ZA and ASUS
     model S5402ZA (Tamim Khan, Kellen Renshaw)

   - Fix acpi_dev_state_d0() kerneldoc (Sakari Ailus)

   - Fix up suspend-to-idle support on ASUS Rembrandt laptops (Mario
     Limonciello)

   - Clean up ACPI platform devices support code (Andy Shevchenko, John
     Garry)

   - Clean up ACPI bus management code (Andy Shevchenko, ye xingchen)

   - Add support for multiple DMA windows with different offsets to the
     ACPI device enumeration code and use it on LoongArch (Jianmin Lv)

   - Clean up the ACPI LPSS (Intel SoC) driver (Andy Shevchenko)

   - Add a quirk for Dell Inspiron 14 2-in-1 for StorageD3Enable (Mario
     Limonciello)

   - Drop unused dev_fmt() and redundant 'HMAT' prefix from the HMAT
     parsing code (Liu Shixin)

   - Make ACPI FPDT parsing code avoid calling acpi_os_map_memory() on
     invalid physical addresses (Hans de Goede)

   - Silence missing-declarations warning related to Apple device
     properties management (Lukas Wunner)

   - Disable frequency invariance in the CPPC library if registers used
     by cppc_get_perf_ctrs() are accessed via PCC (Jeremy Linton)

   - Add ACPI disabled check to acpi_cpc_valid() (Perry Yuan)

   - Fix Tx acknowledge in the PCC address space handler (Huisong Li)

   - Use wait_for_completion_timeout() for PCC mailbox operations
     (Huisong Li)

   - Release resources on PCC address space setup failure path (Rafael
     Mendonca)

   - Remove unneeded result variables from APEI code (ye xingchen)

   - Print total number of records found during BERT log parsing (Dmitry
     Monakhov)

   - Drop support for 3 _OSI strings that should not be necessary any
     more and update documentation on custom _OSI strings so that adding
     new ones is not encouraged any more (Mario Limonciello)

   - Drop unneeded result variable from ec_write() (ye xingchen)

   - Remove the leftover struct acpi_ac_bl from the ACPI AC driver
     (Hanjun Guo)

   - Reorder symbols to get rid of a few forward declarations in the
     ACPI fan driver (Uwe Kleine-König)

   - Add Toshiba Satellite/Portege Z830 ACPI backlight quirk (Arvid
     Norlander)

   - Add ARM DMA-330 controller to the supported list in the ACPI AMBA
     driver (Vijayenthiran Subramaniam)

   - Drop references to non-functional 01.org/linux-acpi web site from
     MAINTAINERS and Kconfig help texts (Rafael Wysocki)

   - Replace strlcpy() with unused retval with strscpy() in the ACPI
     support code (Wolfram Sang)

   - Do not initialize ret in main() in the pfrut utility (Shi junming)

   - Drop useless ACPI DSDT override documentation (Rafael Wysocki)

   - Fix a few typos and wording mistakes in the ACPI device enumeration
     documentation (Jean Delvare)

   - Introduce acpi_dev_uid_to_integer() to convert a _UID string into
     an integer value (Andy Shevchenko)

   - Use acpi_dev_uid_to_integer() in several places to unify _UID
     handling (Andy Shevchenko)

   - Drop unused pnpid32_to_pnpid() declaration from PNP code (Gaosheng
     Cui)"
