Merge tag 'acpi-5.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull ACPI updates from Rafael Wysocki:
 "These update the ACPICA kernel code to upstream revision 20210730,
  clean up the ACPI companion binding code, optimize the I2C handling in
  the XPower PMIC driver, add 16550-compatible Serial Port Subtype
  support to the SPCR parsing code, add a few LoongArch support bits,
  add a ne quirk to the button driver, add new PCH FIVR methods to the
  DPTF code, replace deprecated CPU-hotplug functions in the processor
  driver, improve the acpi_os_map_memory() handling on non-x86 and do
  some assorted cleanups.

  Specifics:

   - Update ACPICA code in the kernel to upstream revision 20210730
     including the following changes:
       - Add support for the AEST table (data compiler) to iASL (Bob
         Moore)
       - Fix an if statement (add parens) (Bob Moore)
       - Drop trailing semicolon from some macros (Bob Moore)
       - Fix compilation of WPBT table with no command-line arguments in
         iASL (Bob Moore)
       - Add method name "_DIS" for use with aslmethod.c (Bob Moore)
       - Add new DBG2 Serial Port Subtypes (Marcin Wojtas)

   - Add new PCH FIVR methods to the DPTF code (Srinivas Pandruvada)

   - Add support for the new 16550-compatible Serial Port Subtype to the
     SPCR table parsing code (Marcin Wojtas)

   - Add DMI quirk for Lenovo Yoga 9 (14INTL5) to the ACPI button driver
     (Ulrich Huber)

   - Add LoongArch support for ACPI_PROCESSOR/ACPI_NUMA (Huacai Chen)

   - Add memory semantics to acpi_os_map_memory() (Lorenzo Pieralisi)

   - Replace deprecated CPU-hotplug functions in the ACPI processor
     driver (Sebastian Andrzej Siewior)

   - Optimize I2C-bus handling in the XPower PMIC driver (Hans de Goede)

   - Make platform-profile catch profile changes initiated by user space
     and notify user processes of them (Hans de Goede)

   - Clean up the ACPI companion binding and unbinding code and update
     debug messaging in the ACPI power resources code (Rafael Wysocki)

   - Clean up a couple of code pieces related to configfs (Andy
     Shevchenko)

   - Rearrange the FPDT table parsing code to avoid printing warning
     messages for reserved record types (Adrian Huang)"
