Merge tag 'acpi-4.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull ACPI updates from Rafael Wysocki:
"The new features here are ACPI 6.1 support (and some previously
missing bits of ACPI 6.0 support) in ACPICA and two new drivers, a
driver for the ACPI Generic Event Device (GED) feature introduced by
ACPI 6.1 and the INT3406 thermal driver for display thermal
management. Also the value returned by the _HRV (hardware revision)
ACPI object will be exported to user space via sysfs now.
In addition to that, ACPI on ARM64 will not depend on EXPERT any more.
The rest is mostly fixes and cleanups and some code reorganization.
Specifics:
- In-kernel ACPICA code update to the upstream release 20160422
adding support for ACPI 6.1 along with some previously missing bits
of ACPI 6.0 support, making a fair amount of fixes and cleanups and
reducing divergences between the upstream ACPICA and the in-kernel
code (Bob Moore, Lv Zheng, Al Stone, Aleksey Makarov, Will Miles)
- ACPI Generic Event Device (GED) support and a fix for it (Sinan
Kaya, Paul Gortmaker)
- INT3406 thermal driver for display thermal management and ACPI
backlight support code reorganization related to it (Aaron Lu, Arnd
Bergmann)
- Support for exporting the value returned by the _HRV (hardware
revision) ACPI object via sysfs (Betty Dall)
- Removal of the EXPERT dependency for ACPI on ARM64 (Mark Brown)
- Rework of the handling of ACPI _OSI mechanism allowing the
_OSI("Darwin") support to be overridden from the kernel command
line among other things (Lv Zheng, Chen Yu)
- Rework of the ACPI tables override mechanism to prepare it for the
introduction of overlays support going forward (Lv Zheng, Rafael
Wysocki)
- Fixes related to the ECDT support and module-level execution of AML
(Lv Zheng)
- ACPI PCI interrupts management update to make it work better on
ARM64 mostly (Sinan Kaya)
- ACPI SRAT handling update to make the code process all entires in
the table order regardless of the entry type (Lukasz Anaczkowski)
- EFI power off support for full-hardware ACPI platforms that don't
support ACPI S5 (Chen Yu)
- Fixes and cleanups related to the ACPI core's sysfs interface (Dan
Carpenter, Betty Dall)
- acpi_dev_present() API rework to reduce possible confusion related
to it (Lukas Wunner)
- Removal of CLK_IS_ROOT from two ACPI drivers (Stephen Boyd)"
