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)"
