Linaro 16.09

sound updates for 4.9-rc1

Again the diffstat shows a widely distributed pattern at this cycle,
as there've been many code cleanups and refactoring allover the places.
Other than that, the development was relatively calm, and no big
surprise shouldn't be expected.  Here are some highlights:

Core:
- Sequencer code refactoring / documentation updates
- TLV code moved to uapi, following some relevant cleanups

USB-Audio:
- Lots of LINE6 driver fixes / updates
- DragonFly and TEAC device quirk updates

HD-audio:
- Usual fixupes for Dell, Lenovo and HP machines
- Link-audio time reporting capability

ASoC:
- Large refactoring of simple-card code to be shared with rcar
  driver
- Removal of some duplicated ops over lots of CODEC drivers
- Again quite a few Intel SKL driver updates
- New drivers for Nuvoton NAU88C10, Realtek RT5660 and RT5663

DeviceTree updates for 4.9:

- Update changeset documentation on locking to reflect current code

- Fix alphabetizing of vendor-prefixes.txt

- Add various vendor prefixes

- Add ESP8089 WiFi binding

- Add new variable sized array parsing functions

This is the bulk of GPIO changes for the v4.9 series:

Subsystem improvements:

- Do away with the last users of the obsolete Kconfig options
  ARCH_REQUIRE_GPIOLIB and ARCH_WANT_OPTIONAL_GPIOLIB (the latter
  always sounded like an item on a wishlist to Santa Claus to
  me). We can now select GPIOLIB and be done with it, for all
  archs. After some struggle it even work on UM. Not that it has
  GPIO, but if it wants to, it can select the library.

- Continued efforts to make drivers properly either tristate or
  bool.

- Introduce a warning for drivers assigning default triggers to
  their irqchip lines when probed from device tree, so we find and
  fix these ambigous drivers. It is agreed that in the OF config
  path, the device tree defines trigger characteristics.

- The same warning, mutatis mutandis, for ACPI-probed GPIO
  irqchips.

- We introduce the ability to mark certain IRQ lines as "unusable"
  as they can be taken by BIOS/firmware, unrouted in silicon and
  generally nasty if you use them, and such things. This is
  put to good use in the STMPE driver and also in the Cherryview
  pin control driver.

- A new "mockup" virtual GPIO device that can be used for testing.
  The plan is to add unit tests under tools/* for exercising this
  device and verify that the kernel code paths are working as they
  should.

- Make memory-mapped I/O-drivers depend on HAS_IOMEM. This was
  implicit all the time, but when people started building UM
  with allyesconfig or allmodconfig it exploded in their face.

- Move some stray bits of device tree and ACPI HW description
  callbacks down into their respective implementation silo. These
  were causing issues when compiling on !HAS_IOMEM as well, so
  now eventually UM compiles the GPIOLIB library if it wants to.

New drivers:

- New driver for the Aspeed GPIO front-end companion to the
  pin controller merged through the pin control tree.

- New driver for the LP873x PMIC GPIO portions.

- New driver for Technologic Systems' I2C FPGA GPIO such as
  TS4900, TS-7970, TS-7990 and TS-4100.

- New driver for the Broadcom BCM63xx series including BCM6338
  and BCM6345.

- New driver for the Intel WhiskeyCove PMIC GPIO.

- New driver for the Allwinner AXP209 PMIC GPIO portions.

- New driver for Diamond Systems 48 line GPIO-MM, another of
  these port-mapped I/O expansion cards.

- Support the STMicroelectronics STMPE1600 variant in the STMPE
  driver.

Driver improvements:

- The STMPE driver now supports rising/falling edge detection
  properly for IRQs.

- The PCA954x will now fetch and enable its VCC regulator properly.

- Major rework of the PCA953x driver with the goal of eventually
  switching it over to use regmap and thus modernize it even more.

- Switch the IOP driver to use the generic MMIO GPIO library.

- Move the ages old HTC EGPIO (extended GPIO) GPIO expander driver
  over to this subsystem from MFD, achieveing some separation of
  concerns.

regulator: Changes for v4.9

This is an extremely quiet release for the regulator API, we've got a
small set of bug fixes and minor feature enhancements for drivers plus a
couple of more visible changes:

 - Add support for ramp times in regulators that don't use selectors.
 - New driver for LTC3676.

This time around, we have
 * Neighbor Awareness Networking (NAN) APIs
 * a fix for a previous patch that caused memory corruption
   in wireless extensions key settings
 * beacon rate configuration for AP and mesh
 * memory limits for mac80211's internal TXQs
 * a (fairly involved) fix for the TXQ vs. crypto problems
 * direct cfg80211 driver API for WEP keys

This also pulls in net-next to fix the merge conflicts, see
the merge commit for more details.

This is the 3.12.64 stable release

Linux 4.8

PNP update for v4.9-rc1

This makes more PNP core code explicitly non-modular (Paul Gortmaker).

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.

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).

   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 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:
