Linus Torvalds 7f3fdd40a7 Power management updates for v4.16-rc1
- Define a PM driver flag allowing drivers to request that their
    devices be left in suspend after system-wide transitions to the
    working state if possible and add support for it to the PCI bus
    type and the ACPI PM domain (Rafael Wysocki).
 
  - Make the PM core carry out optimizations for devices with driver
    PM flags set in some cases and make a few drivers set those flags
    (Rafael Wysocki).
 
  - Fix and clean up wrapper routines allowing runtime PM device
    callbacks to be re-used for system-wide PM, change the generic
    power domains (genpd) framework to stop using those routines
    incorrectly and fix up a driver depending on that behavior of
    genpd (Rafael Wysocki, Ulf Hansson, Geert Uytterhoeven).
 
  - Fix and clean up the PM core's device wakeup framework and
    re-factor system-wide PM core code related to device wakeup
    (Rafael Wysocki, Ulf Hansson, Brian Norris).
 
  - Make more x86-based systems use the Low Power Sleep S0 _DSM
    interface by default (to fix power button wakeup from
    suspend-to-idle on Surface Pro3) and add a kernel command line
    switch to tell it to ignore the system sleep blacklist in the
    ACPI core (Rafael Wysocki).
 
  - Fix a race condition related to cpufreq governor module removal
    and clean up the governor management code in the cpufreq core
    (Rafael Wysocki).
 
  - Drop the unused generic code related to the handling of the static
    power energy usage model in the CPU cooling thermal driver along
    with the corresponding documentation (Viresh Kumar).
 
  - Add mt2712 support to the Mediatek cpufreq driver (Andrew-sh Cheng).
 
  - Add a new operating point to the imx6ul and imx6q cpufreq drivers
    and switch the latter to using clk_bulk_get() (Anson Huang, Dong
    Aisheng).
 
  - Add support for multiple regulators to the TI cpufreq driver along
    with a new DT binding related to that and clean up that driver
    somewhat (Dave Gerlach).
 
  - Fix a powernv cpufreq driver regression leading to incorrect CPU
    frequency reporting, fix that driver to deal with non-continguous
    P-states correctly and clean it up (Gautham Shenoy, Shilpasri Bhat).
 
  - Add support for frequency scaling on Armada 37xx SoCs through the
    generic DT cpufreq driver (Gregory CLEMENT).
 
  - Fix error code paths in the mvebu cpufreq driver (Gregory CLEMENT).
 
  - Fix a transition delay setting regression in the longhaul cpufreq
    driver (Viresh Kumar).
 
  - Add Skylake X (server) support to the intel_pstate cpufreq driver
    and clean up that driver somewhat (Srinivas Pandruvada).
 
  - Clean up the cpufreq statistics collection code (Viresh Kumar).
 
  - Drop cluster terminology and dependency on physical_package_id
    from the PSCI driver and drop dependency on arm_big_little from
    the SCPI cpufreq driver (Sudeep Holla).
 
  - Add support for system-wide suspend and resume to the RAPL power
    capping driver and drop a redundant semicolon from it (Zhen Han,
    Luis de Bethencourt).
 
  - Make SPI domain validation (in the SCSI SPI transport driver) and
    system-wide suspend mutually exclusive as they rely on the same
    underlying mechanism and cannot be carried out at the same time
    (Bart Van Assche).
 
  - Fix the computation of the amount of memory to preallocate in the
    hibernation core and clean up one function in there (Rainer Fiebig,
    Kyungsik Lee).
 
  - Prepare the Operating Performance Points (OPP) framework for being
    used with power domains and clean up one function in it (Viresh
    Kumar, Wei Yongjun).
 
  - Clean up the generic sysfs interface for device PM (Andy Shevchenko).
 
  - Fix several minor issues in power management frameworks and clean
    them up a bit (Arvind Yadav, Bjorn Andersson, Geert Uytterhoeven,
    Gustavo Silva, Julia Lawall, Luis de Bethencourt, Paul Gortmaker,
    Sergey Senozhatsky, gaurav jindal).
 
  - Make it easier to disable PM via Kconfig (Mark Brown).
 
  - Clean up the cpupower and intel_pstate_tracer utilities (Doug
    Smythies, Laura Abbott).

Merge tag 'pm-4.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull power management updates from Rafael Wysocki:
 "This includes some infrastructure changes in the PM core, mostly
  related to integration between runtime PM and system-wide suspend and
  hibernation, plus some driver changes depending on them and fixes for
  issues in that area which have become quite apparent recently.

  Also included are changes making more x86-based systems use the Low
  Power Sleep S0 _DSM interface by default, which turned out to be
  necessary to handle power button wakeups from suspend-to-idle on
  Surface Pro3.

  On the cpufreq front we have fixes and cleanups in the core, some new
  hardware support, driver updates and the removal of some unused code
  from the CPU cooling thermal driver.

  Apart from this, the Operating Performance Points (OPP) framework is
  prepared to be used with power domains in the future and there is a
  usual bunch of assorted fixes and cleanups.

  Specifics:

   - Define a PM driver flag allowing drivers to request that their
     devices be left in suspend after system-wide transitions to the
     working state if possible and add support for it to the PCI bus
     type and the ACPI PM domain (Rafael Wysocki).

   - Make the PM core carry out optimizations for devices with driver PM
     flags set in some cases and make a few drivers set those flags
     (Rafael Wysocki).

     power domains (genpd) framework to stop using those routines
     incorrectly and fix up a driver depending on that behavior of genpd
     (Rafael Wysocki, Ulf Hansson, Geert Uytterhoeven).

   - Fix and clean up the PM core's device wakeup framework and
     re-factor system-wide PM core code related to device wakeup
     (Rafael Wysocki, Ulf Hansson, Brian Norris).

     suspend-to-idle on Surface Pro3) and add a kernel command line
     switch to tell it to ignore the system sleep blacklist in the ACPI
     core (Rafael Wysocki).

   - Fix a race condition related to cpufreq governor module removal and
     clean up the governor management code in the cpufreq core (Rafael
     Wysocki).

   - Drop the unused generic code related to the handling of the static
     power energy usage model in the CPU cooling thermal driver along

   - Drop cluster terminology and dependency on physical_package_id from
     the PSCI driver and drop dependency on arm_big_little from the SCPI
     cpufreq driver (Sudeep Holla).

   - Add support for system-wide suspend and resume to the RAPL power
     capping driver and drop a redundant semicolon from it (Zhen Han,
     Luis de Bethencourt).

   - Make SPI domain validation (in the SCSI SPI transport driver) and
     system-wide suspend mutually exclusive as they rely on the same
     underlying mechanism and cannot be carried out at the same time
     (Bart Van Assche).

   - Fix the computation of the amount of memory to preallocate in the
     hibernation core and clean up one function in there (Rainer Fiebig,
     Kyungsik Lee).

   - Prepare the Operating Performance Points (OPP) framework for being
