Pull ACPI updates from Rafael Wysocki:
 "These add support for generic initiator-only proximity domains to the
  ACPI NUMA code and the architectures using it, clean up some
  non-ACPICA code referring to debug facilities from ACPICA, reduce the
  overhead related to accessing GPE registers, add a new DPTF (Dynamic
  Power and Thermal Framework) participant driver, update the ACPICA
  code in the kernel to upstream revision 20200925, add a new ACPI
  backlight whitelist entry, fix a few assorted issues and clean up some
  code.

  Specifics:

   - Add support for generic initiator-only proximity domains to the
     ACPI NUMA code and the architectures using it (Jonathan Cameron)

   - Clean up some non-ACPICA code referring to debug facilities from
     ACPICA that are not actually used in there (Hanjun Guo)

   - Add new DPTF driver for the PCH FIVR participant (Srinivas
     Pandruvada)

   - Reduce overhead related to accessing GPE registers in ACPICA and
     the OS interface layer and make it possible to access GPE registers
     using logical addresses if they are memory-mapped (Rafael Wysocki)

   - Update the ACPICA code in the kernel to upstream revision 20200925
     including changes as follows:
      + Add predefined names from the SMBus sepcification (Bob Moore)
      + Update acpi_help UUID list (Bob Moore)
      + Return exceptions for string-to-integer conversions in iASL (Bob
        Moore)
      + Add a new "ALL <NameSeg>" debugger command (Bob Moore)
      + Add support for 64 bit risc-v compilation (Colin Ian King)
      + Do assorted cleanups (Bob Moore, Colin Ian King, Randy Dunlap)

   - Add new ACPI backlight whitelist entry for HP 635 Notebook (Alex
     Hung)

   - Move TPS68470 OpRegion driver to drivers/acpi/pmic/ and split out
     Kconfig and Makefile specific for ACPI PMIC (Andy Shevchenko)

   - Clean up the ACPI SoC driver for AMD SoCs (Hanjun Guo)

   - Add missing config_item_put() to fix refcount leak (Hanjun Guo)

   - Drop lefrover field from struct acpi_memory_device (Hanjun Guo)

   - Make the ACPI extlog driver check for RDMSR failures (Ben
     Hutchings)

   - Fix handling of lid state changes in the ACPI button driver when
     input device is closed (Dmitry Torokhov)

   - Fix several assorted build issues (Barnabás Pőcze, John Garry,
     Nathan Chancellor, Tian Tao)

   - Drop unused inline functions and reduce code duplication by using
     kobj_to_dev() in the NFIT parsing code (YueHaibing, Wang Qing)

   - Serialize tools/power/acpi Makefile (Thomas Renninger)"
