      Pull device properties framework updates from Rafael Wysocki:
       "These introduce fwnode operations for all of the separate types of
        'firmware nodes' that can be handled by the device properties
        framework, make the framework use const fwnode arguments all over, add
        a helper for the consolidated handling of node references and switch
        over the framework to the new UUID API.
         - Introduce fwnode operations for all of the separate types of
           'firmware nodes' that can be handled by the device properties
           framework and drop the type field from struct fwnode_handle (Sakari
           Ailus, Arnd Bergmann).
         - Make the device properties framework use const fwnode arguments
           where possible (Sakari Ailus).
         - Add a helper for the consolidated handling of node references to
           the device properties framework (Sakari Ailus).

           due to a delay in GPE enabling (Rafael Wysocki).
         - Rework the handling of PCI bridges when setting up ACPI-based
           device wakeup in order to avoid disabling wakeup for bridges
           prematurely (Rafael Wysocki).
         - Consolidate Apple DMI checks throughout the tree, add support for
           Apple device properties to the device properties framework and use
           these properties for the handling of I2C and SPI devices on Apple
           systems (Lukas Wunner).
         - Add support for _DMA to the ACPI-based device properties lookup

         - Add a new utility function to the ACPI core to support using ACPI
           OEM ID / OEM Table ID / Revision for system identification in
           blacklisting or similar and switch over the existing code already
           using this information to this new interface (Toshi Kani).
         - Fix an xpower PMIC issue related to GPADC reads that always return
           0 without extra pin manipulations (Hans de Goede).

      Pull power management updates from Rafael Wysocki:
       "This time (again) cpufreq gets the majority of changes which mostly
        are driver updates (including a major consolidation of intel_pstate),
        some schedutil governor modifications and core cleanups.
        There also are some changes in the system suspend area, mostly related
        to diagnostics and debug messages plus some renames of things related
        to suspend-to-idle. One major change here is that suspend-to-idle is
        now going to be preferred over S3 on systems where the ACPI tables
        indicate to do so and provide requsite support (the Low Power Idle S0
        _DSM in particular). The system sleep documentation and the tools
        related to it are updated too.
        The rest is a few cpuidle changes (nothing major), devfreq updates,
        generic power domains (genpd) framework updates and a few assorted
        modifications elsewhere.
         - Drop the P-state selection algorithm based on a PID controller from
           intel_pstate and make it use the same P-state selection method
           (based on the CPU load) for all types of systems in the active mode
           (Rafael Wysocki, Srinivas Pandruvada).
         - Rework the cpufreq core and governors to make it possible to take
           cross-CPU utilization updates into account and modify the schedutil
           governor to actually do so (Viresh Kumar).
         - Clean up the handling of transition latency information in the
           cpufreq core and untangle it from the information on which drivers
           cannot do dynamic frequency switching (Viresh Kumar).
         - Add support for new SoCs (MT2701/MT7623 and MT7622) to the mediatek
           cpufreq driver and update its DT bindings (Sean Wang).
         - Modify the cpufreq dt-platdev driver to autimatically create
           cpufreq devices for the new (v2) Operating Performance Points (OPP)
           DT bindings and update its whitelist of supported systems (Viresh
           Kumar, Shubhrajyoti Datta, Marc Gonzalez, Khiem Nguyen, Finley
         - Add support for Ux500 to the cpufreq-dt driver and drop the
           obsolete dbx500 cpufreq driver (Linus Walleij, Arnd Bergmann).
         - Add new SoC (R8A7795) support to the cpufreq rcar driver (Khiem
         - Fix and clean up assorted issues in the cpufreq drivers and core
           (Arvind Yadav, Christophe Jaillet, Colin Ian King, Gustavo Silva,
           Julia Lawall, Leonard Crestez, Rob Herring, Sudeep Holla).
         - Update the IO-wait boost handling in the schedutil governor to make
           it less aggressive (Joel Fernandes).
         - Rework system suspend diagnostics to make it print fewer messages
           to the kernel log by default, add a sysfs knob to allow more
           suspend-related messages to be printed and add Low Power S0 Idle
           constraints checks to the ACPI suspend-to-idle code (Rafael
           Wysocki, Srinivas Pandruvada).
         - Prefer suspend-to-idle over S3 on ACPI-based systems with the
           ACPI_FADT_LOW_POWER_S0 flag set and the Low Power Idle S0 _DSM
           interface present in the ACPI tables (Rafael Wysocki).
         - Update documentation related to system sleep and rename a number of
           items in the code to make it cleare that they are related to
           suspend-to-idle (Rafael Wysocki).
         - Export a variable allowing device drivers to check the target
           system sleep state from the core system suspend code (Florian
         - Clean up the cpuidle subsystem to handle the polling state on x86
           in a more straightforward way and to use %pOF instead of full_name
           (Rafael Wysocki, Rob Herring).
         - Update the devfreq framework to fix and clean up a few minor issues
           (Chanwoo Choi, Rob Herring).
         - Extend diagnostics in the generic power domains (genpd) framework
           and clean it up slightly (Thara Gopinath, Rob Herring).
         - Fix and clean up a couple of issues in the operating performance
           points (OPP) framework (Viresh Kumar, Waldemar Rymarkiewicz).
         - Add support for RV1108 to the rockchip-io Adaptive Voltage Scaling
           (AVS) driver (David Wu).
         - Fix the usage of notifiers in CPU power management on some
           platforms (Alex Shi).
         - Update the pm-graph system suspend/hibernation and boot profiling
           utility (Todd Brandt).

      Pull GPIO updates from Linus Walleij:
       "This is the bulk of the GPIO changes for the v4.14 cycle.
        Not so much changes this time, phew. David Daney and Bartosz
        Golaszewski did all the really interesting work in infrastructure
        improvement across GPIO and IRQ core, hats off for them and to tglx
        and Marc Z for general help with these patch sets.
        Core changes:
         - Allow the GPIO irqchip to allocate IRQs dynamically. This is an
           important change on systems where only a restricted number of IRQs,
           lesser than the number of GPIO lines, can be utilized. Now we can
           allocate these on a first-come-first-served basis instead of
           hogging up valuable IRQ lines.
         - Serious fix-up of the kerneldoc documentation and inclusion into
           the kerneldoc builds.
         - Pulled in the IRQ simulator from the IRQ core tree and use this in
           the GPIO mockup driver for exhaustive testing of interrupt
        New drivers:
         - New driver for ThunderX and OCTEON-TX. This is especially
           interesting as it picks up improvements from the IRQ core that
           allow us to handle fasteoi ACKs upwards in a hierarchy when there
           are IRQ flag latches on several levels in a hierarchy. Very
           interesting work here.
         - New subdriver for Renesas R-Car r8a7745 (RZ/G1E).
         - Several fixes and improvements for Xilinx Zynq GPIO.
         - Support an enablement GPIO for the 74x164 GPIO.
         - Switch a bunch of chips to use devres to allocate irq descriptors.
         - A bunch of constification fixes"
