Merge tag 'acpi-5.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull ACPI updates from Rafael Wysocki:
 "These update the ACPICA code in the kernel to upstream revision
  20210105, fix and clean up the handling of device properties, add
  support for setting global profile of the platform, clean up device
  enumeration, the CPPC library, the APEI support and more, update the
  documentation, consolidate the printing of messages in several places
  and make assorted janitorial changes.

  Specifics:

   - Update ACPICA code in the kernel to upstream revision 20201113 with
     changes as follows:

      * Remove the MTMR (Mid-Timer) table (Al Stone).
      * Remove the VRTC table (Al Stone).
      * Add type casts for string functions (Bob Moore).
      * Update all copyrights to 2021 (Bob Moore).
      * Fix exception code class checks (Maximilian Luz).
      * Clean up exception code class checks (Maximilian Luz).
      * Fix -Wfallthrough (Nick Desaulniers).

   - Add support for setting and reading global profile of the platform
     along with documentation (Mark Pearson, Hans de Goede, Jiaxun
     Yang).

   - Fix fwnode properties matching and clean up the code handling
     device properties and its documentation (Rafael Wysocki, Andy
     Shevchenko).

   - Clean up ACPI-based device enumeration code (Rafael Wysocki).

   - Clean up the CPPC support library code (Ionela Voinescu).

   - Clean up the APEI support code (Yang Li, Yazen Ghannam).

   - Update GPIO-related properties documentation (Flavio Suligoi).

   - Consolidate and clean up the printing of messages in several places
     (Rafael Wysocki).

   - Fix error code path in configfs handling code (Qinglang Miao).

   - Use DEVICE_ATTR_<RW|RO|WO> macros where applicable (Dwaipayan Ray).

   - Replace tests for !ACPI_FAILURE with tests for ACPI_SUCCESS in
     multiple places (Bjorn Helgaas)"
