Merge tag 'acpi-4.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull ACPI updates from Rafael Wysocki:
 "These revert two ACPICA commits that are not needed any more, rework
  the property graphs support in ACPI to be more aligned with the
  analogous DT code, add some new quirks and remove one that isn't
  needed any more, add a special platform driver to enumerate multiple
  I2C devices hooked up to the same device object in the ACPI tables and
  update the battery and button drivers.

  Specifics:

   - Revert two ACPICA commits that are not needed any more (Erik
     Schmauss).

   - Rework property graph support in the ACPI device properties
     framework to make it behave more like the analogous DT code and
     update the documentation of it (Sakari Ailus).

   - Change the default ACPI device status after initialization to
     ACPI_STA_DEFAULT instead of 0 (Hans de Goede).

   - Add a special platform driver for enumerating multiple I2C devices
     hooked up to the same object in the ACPI tables (Hans de Goede).

   - Fix the ACPI battery driver to avoid reporting full capacity on
     systems without support for that and clean it up (Hans de Goede,
     Dmitry Rozhkov, Lucas Rangit Magasweran).

   - Add two system wakeup quirks to the ACPI EC driver (Aaron Ma, Mika
     Westerberg).

   - Add the touchscreen on Dell Venue Pro 7139 to the list of "always
     present" devices to make it work (Tristian Celestin).

   - Revert a special tables handling quirk for Dell XPS 9570 and
     Precision M5530 which is not needed any more (Kai Heng Feng).

   - Add support for a new OEM _OSI string to allow system vendors to
     work around issues with NVidia HDMI audio (Alex Hung).

   - Prevent the ACPI button driver from reporting excessive system
     wakeup events and clean it up (Ravi Chandra Sadineni, Randy
     Dunlap).

   - Clean up two minor code style issues in the ACPI core and GHES
     handling on ARM64 (Dongjiu Geng, John Garry, Tom Todd)"
