Pull ACPI updates from Rafael Wysocki:
 "From the new functionality perspective, the most significant items
  here are the new driver for the 'ARM Generic Diagnostic Dump and
  Reset' device, the extension of fine grain fan control in the ACPI fan
  driver, and the change making it possible to use CPPC information to
  obtain CPU capacity.

  There are also a few new quirks, a bunch of fixes, including the
  platform-level _OSC handling change to make it actually take the
  platform firmware response into account, some code and documentation
  cleanups, and a notable update of the ACPI device enumeration
  documentation.

  Specifics:

   - Use uintptr_t and offsetof() in the ACPICA code to avoid compiler
     warnings regarding NULL pointer arithmetic (Rafael Wysocki).

   - Fix possible NULL pointer dereference in acpi_ns_walk_namespace()
     when passed "acpi=off" in the command line (Rafael Wysocki).

   - Fix and clean up acpi_os_read/write_port() (Rafael Wysocki).

   - Introduce acpi_bus_for_each_dev() and use it for walking all ACPI
     device objects in the Type C code (Rafael Wysocki).

   - Fix the _OSC platform capabilities negotioation and prevent CPPC
     from being used if the platform firmware indicates that it not
     supported via _OSC (Rafael Wysocki).

   - Use ida_alloc() instead of ida_simple_get() for ACPI enumeration of
     devices (Rafael Wysocki).

   - Add AGDI and CEDT to the list of known ACPI table signatures (Ilkka
     Koskinen, Robert Kiraly).

   - Add power management debug messages related to suspend-to-idle in
     two places (Rafael Wysocki).

   - Fix __acpi_node_get_property_reference() return value and clean up
     that function (Andy Shevchenko, Sakari Ailus).

   - Fix return value of the __setup handler in the ACPI PM timer clock
     source driver (Randy Dunlap).

   - Clean up double words in two comments (Tom Rix).

   - Add "skip i2c clients" quirks for Lenovo Yoga Tablet 1050F/L and
     Nextbook Ares 8 (Hans de Goede).

   - Clean up frequency invariance handling on x86 in the ACPI CPPC
     library (Huang Rui).

   - Work around broken XSDT on the Advantech DAC-BJ01 board (Mark
     Cilissen).

   - Make wakeup events checks in the ACPI EC driver more
     straightforward and clean up acpi_ec_submit_event() (Rafael
     Wysocki).

   - Make it possible to obtain the CPU capacity with the help of CPPC
     information (Ionela Voinescu).

   - Improve fine grained fan control in the ACPI fan driver and
     document it (Srinivas Pandruvada).

   - Add device HID and quirk for Microsoft Surface Go 3 to the ACPI
     battery driver (Maximilian Luz).

   - Make the ACPI driver for Intel SoCs (LPSS) let the SPI driver know
     the exact type of the controller (Andy Shevchenko).

   - Force native backlight mode on Clevo NL5xRU and NL5xNU (Werner
     Sembach).

   - Fix return value of __setup handlers in the APEI code (Randy
     Dunlap).

   - Add Arm Generic Diagnostic Dump and Reset device driver (Ilkka
     Koskinen).

   - Limit printable size of BERT table data (Darren Hart).

   - Fix up HEST and GHES initialization (Shuai Xue).

   - Update the ACPI device enumeration documentation and unify the ASL
     style in GPIO-related examples (Andy Shevchenko)"
