Pull more power management and ACPI updates from Rafael Wysocki: "The only new feature in this batch is support for the ACPI _CCA device configuration object, which it a pre-requisite for future ACPI PCI support on ARM64, but should not affect the other architectures. The rest is fixes and cleanups, mostly in cpufreq (including intel_pstate), the Operating Performace Points (OPP) framework and tools (cpupower and turbostat). Specifics: - Support for the ACPI _CCA configuration object intended to tell the OS whether or not a bus master device supports hardware managed cache coherency and a new set of functions to allow drivers to check the cache coherency support for devices in a platform firmware interface agnostic way (Suravee Suthikulpanit, Jeremy Linton). - ACPI backlight quirks for ESPRIMO Mobile M9410 and Dell XPS L421X (Aaron Lu, Hans de Goede). - Fixes for the arm_big_little and s5pv210-cpufreq cpufreq drivers (Jon Medhurst, Nicolas Pitre). - kfree()-related fixup for the recently introduced CPPC cpufreq frontend (Markus Elfring). - intel_pstate fix reducing kernel log noise on systems where P-states are managed by hardware (Prarit Bhargava). - intel_pstate maintainers information update (Srinivas Pandruvada). - cpufreq core optimization related to the handling of delayed work items used by governors (Viresh Kumar). - Locking fixes and cleanups of the Operating Performance Points (OPP) framework (Viresh Kumar). - Generic power domains framework cleanups (Lina Iyer). - cpupower tool updates (Jacob Tanenbaum, Sriram Raghunathan, Thomas Renninger). - turbostat tool updates (Len Brown)" * tag 'pm+acpi-4.4-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (32 commits) PCI: ACPI: Add support for PCI device DMA coherency PCI: OF: Move of_pci_dma_configure() to pci_dma_configure() of/pci: Fix pci_get_host_bridge_device leak device property: ACPI: Remove unused DMA APIs device property: ACPI: Make use of the new DMA Attribute APIs device property: Adding DMA Attribute APIs for Generic Devices ACPI: Adding DMA Attribute APIs for ACPI Device device property: Introducing enum dev_dma_attr ACPI: Honor ACPI _CCA attribute setting cpufreq: CPPC: Delete an unnecessary check before the function call kfree() PM / OPP: Add opp_rcu_lockdep_assert() to _find_device_opp() PM / OPP: Hold dev_opp_list_lock for writers PM / OPP: Protect updates to list_dev with mutex PM / OPP: Propagate error properly from dev_pm_opp_set_sharing_cpus() cpufreq: s5pv210-cpufreq: fix wrong do_div() usage MAINTAINERS: update for intel P-state driver Creating a common structure initialization pattern for struct option cpupower: Enable disabled Cstates if they are below max latency cpupower: Remove debug message when using cpupower idle-set -D switch cpupower: cpupower monitor reports uninitialized values for offline cpus ...
