Merge tag 'pm+acpi-3.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull ACPI and power management updates from Rafael Wysocki: "Again, ACPICA leads the pack (47 commits), followed by cpufreq (18 commits) and system suspend/hibernation (9 commits). From the new code perspective, the ACPICA update brings ACPI 5.1 to the table, including a new device configuration object called _DSD (Device Specific Data) that will hopefully help us to operate device properties like Device Trees do (at least to some extent) and changes related to supporting ACPI on ARM. Apart from that we have hibernation changes making it use radix trees to store memory bitmaps which should speed up some operations carried out by it quite significantly. We also have some power management changes related to suspend-to-idle (the "freeze" sleep state) support and more preliminary changes needed to support ACPI on ARM (outside of ACPICA). The rest is fixes and cleanups pretty much everywhere. Specifics: - ACPICA update to upstream version 20140724. That includes ACPI 5.1 material (support for the _CCA and _DSD predefined names, changes related to the DMAR and PCCT tables and ARM support among other things) and cleanups related to using ACPICA's header files. A major part of it is related to acpidump and the core code used by that utility. Changes from Bob Moore, David E Box, Lv Zheng, Sascha Wildner, Tomasz Nowicki, Hanjun Guo. - Radix trees for memory bitmaps used by the hibernation core from Joerg Roedel. - Support for waking up the system from suspend-to-idle (also known as the "freeze" sleep state) using ACPI-based PCI wakeup signaling (Rafael J Wysocki). - Fixes for issues related to ACPI button events (Rafael J Wysocki). - New device ID for an ACPI-enumerated device included into the Wildcat Point PCH from Jie Yang. - ACPI video updates related to backlight handling from Hans de Goede and Linus Torvalds. - Preliminary changes needed to support ACPI on ARM from Hanjun Guo and Graeme Gregory. - ACPI PNP core cleanups from Arjun Sreedharan and Zhang Rui. - Cleanups related to ACPI_COMPANION() and ACPI_HANDLE() macros (Rafael J Wysocki). - ACPI-based device hotplug cleanups from Wei Yongjun and Rafael J Wysocki. - Cleanups and improvements related to system suspend from Lan Tianyu, Randy Dunlap and Rafael J Wysocki. - ACPI battery cleanup from Wei Yongjun. - cpufreq core fixes from Viresh Kumar. - Elimination of a deadband effect from the cpufreq ondemand governor and intel_pstate driver cleanups from Stratos Karafotis. - 350MHz CPU support for the powernow-k6 cpufreq driver from Mikulas Patocka. - Fix for the imx6 cpufreq driver from Anson Huang. - cpuidle core and governor cleanups from Daniel Lezcano, Sandeep Tripathy and Mohammad Merajul Islam Molla. - Build fix for the big_little cpuidle driver from Sachin Kamat. - Configuration fix for the Operation Performance Points (OPP) framework from Mark Brown. - APM cleanup from Jean Delvare. - cpupower utility fixes and cleanups from Peter Senna Tschudin, Andrey Utkin, Himangi Saraogi, Rickard Strandqvist, Thomas Renninger" * tag 'pm+acpi-3.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (118 commits) ACPI / LPSS: add LPSS device for Wildcat Point PCH ACPI / PNP: Replace faulty is_hex_digit() by isxdigit() ACPICA: Update version to 20140724.
