Merge tag 'acpi-5.3-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
  20190703, fix up the handling of GPEs in ACPICA, allow some more ACPI
  code to be built on ARM64 platforms, allow BGRT to be overridden, fix
  minor issues and clean up assorted pieces of ACPI code.

  Specifics:

   - Update the ACPICA code in the kernel to upstream revision 20190703
     including:
       - Initial/default namespace creation simplification (Bob Moore).
       - Object initialization sequence update (Bob Moore).
       - Removal of legacy module-level (dead) code (Erik Schmauss).
       - Table load object initialization update (Erik Schmauss,
         Nikolaus Voss).

   - Fix GPE enabling issue in ACPICA causing premature wakeups from
     suspend-to-idle to occur (Rafael Wysocki).

   - Allow ACPI AC and battery drivers to be built on non-X86 (Ard
     Biesheuvel).

   - Fix address space handler removal in the ACPI PMIC driver for Intel
     platforms (Andy Shevchenko).

   - Allow BGRT to be overridden via initrd or configfs (Andrea
     Oliveri).

   - Fix object resolution on table loads via configfs (Nikolaus Voss).

   - Clean up assorted pieces of ACPI code and tools (Colin Ian King,
     Liguang Zhang, Masahiro Yamada).

   - Fix documentation build warning, convert the extcon document to
     ReST and add it to the ACPI documentation (Mauro Carvalho Chehab,
     Qian Cai)"
