Merge tag 'acpi-7.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull ACPI support updates from Rafael Wysocki:
 "The most significant change here is the elimination of struct
  acpi_driver that has no more users in the tree now along with some
  documentation related to it, and a follow-up update to set the "no PM"
  flag for all ACPI devices that are now only going to play the role of
  other devices' "companions" (in analogy with DT nodes).

  There is also a significant update of irqchip code related to ACPI
  done in order to enable GICv5 IWB ACPI probe ordering detection on
  ARM, which involves RISC-V interrupt controller management code
  refactoring to extract generic code from it into the common ACPI IRQ
  code.

  The rest is mostly fixes, including some fallout of the _OSC handling
  rework in 7.0, ACPI CPPC library fixes, a workaround for registering
  ACPI platform devices with overlapping I/O or memory resources, an
  ACPI EC driver fix related to probe deferral on platforms using
  HW-reduced ACPI, two ACPI battery driver fixes and a workaround for
  handling model numbers with unprintable characters in it, probe error
  cleanup and driver unload code path fixes, hardware error reporting
  fixes, documentation fixes, and assorted code cleanups all over.

  Specifics:

   - Eliminate struct acpi_driver whose users have all been converted to
     bind to platform devices or auxiliary devices and set the "no power
     management" flag for all struct acpi_device objects (Rafael
     Wysocki)

   - Avoid complaints regarding missing _OSC features on platforms where
     OSC_CAPABILITIES_MASK_ERROR is set in _OSC error bits even though
     all of the requested features are actually acknowledged (Rafael
     Wysocki)

   - Avoid printing confusing _OSC messages for non-PCIe host bridges
     without _OSC which is a valid configuration (Kazuma Kondo)

   - Use correct region struct for BERT region size check and properly
     map BERT and CCEL data to their ACPI tables (Thomas Renninger)

   - Add acpi_device_clear_deps(), refactor RISC-V interrupt controller
     management code to extract generic code from it into the common
     ACPI IRQ code, and enable GICv5 IWB ACPI probe ordering detection
     on ARM on top of that (Lorenzo Pieralisi)

   - Stop using acpi_device_name() in the PNP core, stop setting
     acpi_device_name/class() in the Xen variant of the ACPI PAD
     (Processor Aggregator Device) driver, and make the Loongarch laptop
     driver stop setting acpi_device_class() (Rafael Wysocki)

   - Fix issues related to the desired_perf register access in the ACPI
     CPPC library and update it to avoid unnecessary overhead (Christian
     Loehle)

   - Simplify acpi_get_pci_dev() with the help of a mutex guard,
     introduce acpi_dev_get_pci_dev() for code that has a struct ACPI
     device for which it wants to get the struct pci_dev pointer of the
     associated PCI device, and use it in the ACPI video bus driver
     (Rafael Wysocki)

   - Avoid registering platform devices with resource overlaps in the
     ACPI core device enumeration code (Rafael Wysocki)

   - Clean up the list of included header files in the NHLT table parser
     and validate the table and record lengths in the FPDT parser (Andy
     Shevchenko and Pengpeng Hou)

   - Unregister the cpufreq notifier on init failure in the ACPI
     processor driver (Can Peng)

   - Validate MADT IOAPIC entry bounds during IOAPIC hotplug lookup in
     the ACPI processor driver (Pengpeng Hou)

   - Avoid _REG disconnect on probe deferrals related to GPIO IRQ in the
     ACPI EC driver (Zhu Ling)

   - Update kerneldoc comments of two structures in the ACPI bus type
     code to use correct struct member names to avoid warnings (Randy
     Dunlap)

   - Use a correct function parameter name in kernel-doc in the ACPI fan
     driver (Randy Dunlap)

   - Update ACPI fan IDs to follow modern style and clean up header file
     inclusions in the ACPI fan driver (Andy Shevchenko)

   - Use devm_acpi_install_notify_handler() to replace a custom
     open-coded devres-based management of an ACPI notify handler in the
     ACPI fan driver (Rafael Wysocki)

   - Adjust charging status validation check in the ACPI battery driver
     to avoid incorrect status reporting (Rafael Wysocki)

   - Merge consecutive battery notifications in the ACPI battery driver
     to reduce the pressure on STA, _BST and _BIX/_BIF ACPI control
     methods and make that driver use kstrtoul() instead of
     sscanf("%lu\n") (Rong Zhang)

   - Sanitise model_number in the ACPI battery driver by dropping
     unprintable characters (Kate Hsuan)

   - Remove a node_set() call that is redundant from
     acpi_parse_memory_affinity() (Sang-Heon Jeon)

   - Prevent kernel-doc warnings by converting 2 function description
     comments to kernel-doc format (Randy Dunlap)

   - Fix docs build error in the ACPI admin-guide documentation (Randy
     Dunlap)

   - Replace __get_free_page() with kmalloc() in the code handling ACPI
     NVS memory during system suspend/resume (Mike Rapoport)

   - Fix card device cleanup on registration failure in the core PNP
     code (Yuho Choi)

   - Drop an unused assignment of pnp_device_id driver data (Uwe
     Kleine-König)

   - Clear driver_data on all paths that free acpi_pci_root in
     acpi_pci_root_add() (Chen Pei)

   - Add locking around evaluation of ACPI control methods in the ACPI
     TAD driver to avoid race conditions (Rafael Wysocki)

   - Handle repeated SEA error storms in APEI (Junhao He)

   - Fix ERST timeout unit conversion in APEI (Nirmoy Das)

   - Fix ARM section length accounting after header in the ACPI APEI
     GHES driver (TanZheng)

   - Mark ghes_in_nmi_spool_from_list() as maybe unused (Rui Qi)

   - Introduce helper function acpi_dev_is_video_device() and use it in
     the core ACPI device enumeration code, in the ACPI video bus
     driver, in the ACPI support code for I2C, in the PCI VGA driver,
     and in the x86 platform thinkpad_acpi driver (Andy Shevchenko)

   - Add a quirk to use the native backlight on Acer Nitro AN515-46 to
     the ACPI video bus driver (Marcos Paulo Medeiros)

   - Release PCI device reference after lookup in
     video_detect_portege_r100() in the ACPI video bus driver (Yuho
     Choi)"
