Merge tag 'acpi-4.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull ACPI updates from Rafael Wysocki:
 "These update ACPICA to upstream revision 20170831, fix APEI to use the
  fixmap instead of ioremap_page_range(), add an operation region driver
  for TI PMIC TPS68470, add support for PCC subspace IDs to the ACPI
  CPPC driver, fix a few assorted issues and clean up some code.

  Specifics:

   - Update the ACPICA code to upstream revision 20170831 including
      * PDTT table header support (Bob Moore).
      * Cleanup and extension of internal string-to-integer conversion
        functions (Bob Moore).
      * Support for 64-bit hardware accesses (Lv Zheng).
      * ACPI PM Timer code adjustment to deal with 64-bit return values
        of acpi_hw_read() (Bob Moore).
      * Support for deferred table verification in acpiexec (Lv Zheng).

   - Fix APEI to use the fixmap instead of ioremap_page_range() which
     cannot work correctly the way the code in there attempted to use it
     and drop some code that's not necessary any more after that change
     (James Morse).

   - Clean up the APEI support code and make it use 64-bit timestamps
     (Arnd Bergmann, Dongjiu Geng, Jan Beulich).

   - Add operation region driver for TI PMIC TPS68470 (Rajmohan Mani).

   - Add support for PCC subspace IDs to the ACPI CPPC driver (George
     Cherian).

   - Fix an ACPI EC driver regression related to the handling of EC
     events during the "noirq" phases of system suspend/resume (Lv
     Zheng).

   - Delay the initialization of the lid state in the ACPI button driver
     to fix issues appearing on some systems (Hans de Goede).

   - Extend the KIOX000A "device always present" quirk to cover all
     affected BIOS versions (Hans de Goede).

   - Clean up some code in the ACPI core and drivers (Colin Ian King,
     Gustavo Silva)"

config TPS68470_PMIC_OPREGION
bool "ACPI operation region support for TPS68470 PMIC"
depends on MFD_TPS68470
help
This config adds ACPI operation region support for TI TPS68470 PMIC.
TPS68470 device is an advanced power management unit that powers
a Compact Camera Module (CCM), generates clocks for image sensors,
drives a dual LED for flash and incorporates two LED drivers for
general purpose indicators.
This driver enables ACPI operation region support control voltage
regulators and clocks.
This option is a bool as it provides an ACPI operation
region, which must be available before any of the devices
using this, are probed.
