ACPI material for v4.9-rc1

 - Update of the ACPICA code in the kernel to upstream revision 20160831 with
   the following major changes:
   * New mechanism for GPE masking.
   * Fixes for issues related to the LoadTable operator and table loading.
   * Fixes for issues related to so-called module-level code (MLC), that is
     AML that doesn't belong to any methods.
   * Change of the return value of the _OSI method to reflect the Windows
     behavior.
   * GAS (Generic Address Structure) support fix related to 32-bit FADT
     addresses.
   * Elimination of unnecessary FADT version 2 support.
   * ACPI tools fixes and cleanups.
   From Bob Moore, Lv Zheng, and Jung-uk Kim.

 - ACPI sysfs interface updates to fix GPE handling (on top of the new GPE
   masking mechanism in ACPICA) and issues related to table loading (Lv Zheng).

 - New watchdog driver based on the ACPI WDAT (ACPI Watchdog Action Table),
   needed on some platforms to replace the iTCO watchdog that doesn't work there
   and related updates of the intel_pmc_ipc, i2c/i801 and MFD/lcp_ich drivers
   (Mika Westerberg).

 - Driver core fix to prevent it from leaking secondary fwnode objects during
   device removal (Lukas Wunner).

 - New definitions of built-in properties for UART in ACPI-based x86 SoC drivers
   and a 8250_dw driver quirk for the APM X-Gene SoC (Heikki Krogerus).

 - New device ID for the Vulcan SPI controller and constification of local
   strucures in the AMD SoC (APD) ACPI driver (Kamlakant Patel, Julia Lawall).

 - Fix for a bug causing the allocation of PCI resorces to fail if
   ACPI-enumerated child platform devices are registered below the PCI
   devices in question (Mika Westerberg).

 - Change of the default polarity for PCI legacy IRQs to high on systems
   booting wth ACPI on platforms with a GIC interrupt controller model
   fixing the discrepancy between the specification and HW behavior (Lorenzo
   Pieralisi).

 - Fixes for the handling of system suspend/resume in the ACPI EC driver and
   update of that driver to make it cope with the cases when the EC device
   defined in the ECDT has to be used throughout the entire system life cycle
   (Lv Zheng).

 - Update of the ACPI CPPC library to allow it to batch requests sent over the
   PCC channel (to reduce overhead), to support the fixed functional hardware
   (FFH) CPPC registers access type, to notify the mailbox framework about TX
   completions when the interrupt flag is set for the PCC mailbox, and to
   support HW-Reduced Communication Subspace type 2 (Ashwin Chaugule, Prashanth
   Prakash, Srinivas Pandruvada, Hoan Tran).

 - ACPI button driver fix and documentation update related to the handling of
   laptop lids (Lv Zheng).

 - ACPI battery driver initialization fix (Carlos Garnacho).

 - ACPI GPIO enumeration documentation update (Mika Westerberg).

 - Assorted updates of the core ACPI bus type code (Lukas Wunner, Lv Zheng).

 - Assorted cleanups of the ACPI table parsing code and the x86-specific ACPI
   code (Al Stone).

 - Fixes for assorted ACPI-related issues found in linux-next (Wei Yongjun).

Power management material for v4.9-rc1

 - Add a mechanism for passing hints from the scheduler to cpufreq governors
   via their utilization update callbacks and use it to introduce "IOwait
   boosting" into the schedutil governor and intel_pstate that will make them
   boost performance if the enqueued task was previously waiting on I/O
   (Rafael Wysocki).

 - Fix a schedutil governor problem that causes it to overestimate utilization
   if SMT is in use (Steve Muckle).

 - Update defconfigs trying to use the schedutil governor as a module which is
   not possible any more (Javier Martinez Canillas).

 - Update the intel_pstate's pstate_sample tracepoint to take "IOwait boosting"
   into account (Srinivas Pandruvada).

 - Fix a problem in the cpufreq core causing it to mishandle the initialization
   of CPUs registered after the cpufreq driver (Viresh Kumar, Rafael Wysocki).

 - Make the cpufreq-dt driver support per-policy governor tunables, clean it
   up and update its Kconfig description (Viresh Kumar).

 - Add support for more ARM platforms to the cpufreq-dt driver (Chanwoo Choi,
   Dave Gerlach, Geert Uytterhoeven).

 - Make the cpufreq CPPC driver report frequencies in KHz to avoid user space
   compatiblility issues (Al Stone, Hoan Tran).

 - Clean up a few cpufreq drivers (st, kirkwood, SCPI) a bit (Colin Ian King,
   Markus Elfring).

 - Constify some local structures in the intel_pstate driver (Julia Lawall).

 - Add a Documentation/cpu-freq/ entry to MAINTAINERS (Jean Delvare).

 - Add support for PM domain removal to the generic power domains (genpd)
   framework, add new DT helper functions to it and make it always enable
   debugfs support if available (Jon Hunter, Tomeu Vizoso).

 - Clean up the generic power domains (genpd) framework and make it avoid
   measuring power-on and power-off latencies during system-wide PM transitions
   (Ulf Hansson).

 - Add support for the RockChip DFI controller and the rk3399 DMC to the
   devfreq framework (Lin Huang, Axel Lin, Arnd Bergmann).

 - Add COMPILE_TEST to the devfreq framework (Krzysztof Kozlowski, Stephen
   Rothwell).

 - Fix a minor issue in the exynos-ppmu devfreq driver and fix up devfreq
   Kconfig indentation style (Wei Yongjun, Jisheng Zhang).

 - Fix the system suspend interface to make suspend-to-idle work if platform
   suspend operations have not been registered (Sudeep Holla).

 - Make it possible to use hibernation with PAGE_POISONING_ZERO enabled
   (Anisse Astier).

 - Increas the default timeout of the system suspend/resume watchdog and make it
   depend on EXPERT (Chen Yu).

 - Make the operating performance points (OPP) framework avoid using OPPs that
   aren't supported by the platform and fix a build warning in it (Dave Gerlach,
   Arnd Bergmann).

 - Fix the ARM cpuidle driver's return value (Christophe Jaillet).

 - Make the SmartReflex AVS (Adaptive Voltage Scaling) driver use more common
   logging style (Joe Perches).

ASoC: Updates for v4.9

Apart from the cleanups done by Morimoto-san this has very much been a
driver focused release with very little generic change:

 - A big factoring out of the simple-card code to allow it to be shared
   more with the rcar generic card from Kuninori Morimoto.
 - Removal of some operations duplicated on the CODEC level, again by
   Kuninori Morimoto.
 - Lots more machine support for x86 systems.
 - New drivers for Nuvoton NAU88C10, Realtek RT5660 and RT5663.

 * Neighbor Awareness Networking (NAN) APIs

Third set of new device support, functionality and cleanups for IIO in the 4.9 cycle.

Given Linus is hinting (strongly!) at an rc8 this last set is hopefully in
time for the 4.9 merge window.  The zpa2326 and si1145 drivers provide
fine illustrations that devices aren't getting any simpler!

I'm also particularly pleased Linus Walliej did such a thorough job of cleaning
up one of my old drivers.

New device support
* mCube MC3230 accelerometer
  - new fairly minimal driver.
* Murata zpa2326
  - extensive new driver supporting the rather 'novel' buffering of data this
    device provides and handling both it's own data ready trigger and other
    triggers rather elegantly.
* si1141, si1142, si1143, si1145, si1146 and si1147 proximity, UV, visible and
  IR sensors.
  - another extensive new driver supporting all the key bits of what this
    set of devices supplies including dataready triggers, buffers and all the
    various data channels.

Functionality
* kxsd9 - Linus brought this scratch driver I wrote in one afternoon years ago
  up to date adding lots of good stuff along the way.
  - SPI support after extensive rework of the driver.
  - Triggered buffer capture support.
  - Runtime PM.
  - Regulator handling.
  - Mounting matrix support.
* mma7660
  - Add MODULE_DEVICE_TABLE to support autoprobing.

Cleanups
* ad5933
  - Align some function arguements nicely.
* med_z188
  - Constify iio_info structure.
* sca3000
  - Implement IIO_CHAN_INFO_SAMP_FREQ rather than a hand rolled attr.
    There are still quite a few drivers that would benefit from similar updates.
* ssp_sensors
  - Constify iio_info structures in accel and gyro drivers.
