      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

         - 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)

      Pull power management updates from Rafael Wysocki:
       "The majority of changes go into the cpufreq subsystem this time.
      
        To me, quite obviously, the biggest ticket item is the new "schedutil"
        governor.  Interestingly enough, it's the first new cpufreq governor
        since the beginning of the git era (except for some out-of-the-tree
        ones).
      
        There are two main differences between it and the existing governors.
        First, it uses the information provided by the scheduler directly for
        making its decisions, so it doesn't have to track anything by itself.
        Second, it can invoke drivers (supporting that feature) to adjust CPU
        performance right away without having to spawn work items to be
        executed in process context or similar.  Currently, the acpi-cpufreq
        driver is the only one supporting that mode of operation, but then it
        is used on a large number of systems.
      
        The "schedutil" governor as included here is very simple and mostly
        regarded as a foundation for future work on the integration of the
        scheduler with CPU power management (in fact, there is work in
        progress on top of it already).  Nevertheless it works and the
        preliminary results obtained with it are encouraging.
      
        There also is some consolidation of CPU frequency management for ARM
        platforms that can add their machine IDs the the new stub dt-platdev
        driver now and that will take care of creating the requisite platform
        device for cpufreq-dt, so it is not necessary to do that in platform
        code any more.  Several ARM platforms are switched over to using this
        generic mechanism.
      
        In addition to that, the intel_pstate driver is now going to respect
        CPU frequency limits set by the platform firmware (or a BMC) and
        provided via the ACPI _PPC object.
      
        The devfreq subsystem is getting a new "passive" governor for SoCs
        subsystems that will depend on somebody else to manage their voltage
        rails and its support for Samsung Exynos SoCs is consolidated.
      
        The rest is support for new hardware (Intel Broxton support in
        intel_idle for one example), bug fixes, optimizations and cleanups in
        a number of places.
      
        Specifics:
      
         - New cpufreq "schedutil" governor (making decisions based on CPU
           utilization information provided by the scheduler and capable of
           switching CPU frequencies right away if the underlying driver
           supports that) and support for fast frequency switching in the
           acpi-cpufreq driver (Rafael Wysocki)
      
         - Consolidation of CPU frequency management on ARM platforms allowing
           them to get rid of some platform-specific boilerplate code if they
           are going to use the cpufreq-dt driver (Viresh Kumar, Finley Xiao,
           Marc Gonzalez)
      
         - Support for ACPI _PPC and CPU frequency limits in the intel_pstate
           driver (Srinivas Pandruvada)
      
         - Fixes and cleanups in the cpufreq core and generic governor code
           (Rafael Wysocki, Sai Gurrappadi)
      
         - intel_pstate driver optimizations and cleanups (Rafael Wysocki,
           Philippe Longepe, Chen Yu, Joe Perches)
      
         - cpufreq powernv driver fixes and cleanups (Akshay Adiga, Shilpasri
           Bhat)

         - Assorted cpufreq fixes and cleanups (Joe Perches, Arnd Bergmann)
      
         - Fixes and cleanups in the OPP (Operating Performance Points)
           framework, mostly related to OPP sharing, and reorganization of
           OF-dependent code in it (Viresh Kumar, Arnd Bergmann, Sudeep Holla)
      
         - New "passive" governor for devfreq (for SoC subsystems that will
           rely on someone else for the management of their power resources)
           and consolidation of devfreq support for Exynos platforms, coding
           style and typo fixes for devfreq (Chanwoo Choi, MyungJoo Ham)
      
         - PM core fixes and cleanups, mostly to make it work better with the
           generic power domains (genpd) framework, and updates for that
           framework (Ulf Hansson, Thierry Reding, Colin Ian King)
      
         - Intel Broxton support for the intel_idle driver (Len Brown)
      
         - cpuidle core optimization and fix (Daniel Lezcano, Dave Gerlach)
      
         - ARM cpuidle cleanups (Jisheng Zhang)

         - When applying constraints at system image if we have a voltage
           range specified and the regulator is currently configured outside

           the range.

           we always use the voltage from the parent regulator.

       "In this merge cycle we had an interaction with MTD subsystem, that
        included converting drivers/mtd/nand/nand_base.c to use newly
        introduced MTD (NAND/NOR) LED trigger instead of implementing it on
        its own.
      
        Related MTD patches are intended to be merged through the LED tree,
        before MTD tree is merged, since further MTD development is based on
        those modifications.

      ipmi: Fix the I2C address extraction from SPMI tables · 70f95b76
      Corey Minyard authored
      Unlike everywhere else in the IPMI specification, the I2C address
      specified in the SPMI table is not shifted to the left one bit with
      the LSB zero.  Instead it is not shifted with the MSB zero.

      IPMI: reserve memio regions separately · 57a38f13
      Corey Minyard authored
      Commit d61a3ead ("[PATCH] IPMI: reserve I/O ports separately")
      changed the way I/O ports were reserved and includes this comment in
      log:
      
       Some BIOSes reserve disjoint I/O regions in their ACPI tables for the IPMI
       controller.  This causes problems when trying to register the entire I/O
       region.  Therefore we must register each I/O port separately.
      
      There is a similar problem with memio regions on an arm64 platform
      (AMD Seattle). Where I see:
      
       ipmi message handler version 39.2
       ipmi_si AMDI0300:00: probing via device tree
       ipmi_si AMDI0300:00: ipmi_si: probing via ACPI
       ipmi_si AMDI0300:00: [mem 0xe0010000] regsize 1 spacing 4 irq 23
       ipmi_si: Adding ACPI-specified kcs state machine
       IPMI System Interface driver.
       ipmi_si: Trying ACPI-specified kcs state machine at mem \
                address 0xe0010000, slave address 0x0, irq 23
       ipmi_si: Could not set up I/O space
      
      The problem is that the ACPI core registers disjoint regions for the
      platform device:
      
      e0010000-e0010000 : AMDI0300:00
      e0010004-e0010004 : AMDI0300:00
      
      and the ipmi_si driver tries to register one region e0010000-e0010004.
      
      Based on a patch from Mark Salter <msalter@redhat.com>, who also wrote
      all the above text.
