media updates for v4.15-rc1

DeviceTree for 4.15:

- kbuild cleanups and improvements for dtbs

- Code clean-up of overlay code and fixing for some long standing memory
  leak and race condition in applying overlays

- Improvements to DT memory usage making sysfs/kobjects optional and
  skipping unflattening of disabled nodes. This is part of kernel
  tinification efforts.

- Final piece of removing storing the full path for every DT node. The
  prerequisite conversion of printk's to use device_node format
  specifier happened in 4.14.

- Sync with current upstream dtc. This brings additional checks to dtb
  compiling.

- Binding doc tree wide removal of leading 0s from examples

- RTC binding documentation adding missing devices and some
  consolidation of duplicated bindings

- Vendor prefix documentation for nutsboard, Silicon Storage Technology,
  shimafuji, Tecon Microprocessor Technologies, DH electronics GmbH,
  Opal Kelly, and Next Thing

sound updates for 4.15-rc1

There are no big surprising changes in this cycle, yet not too
boring, either.  The biggest change from diffstat POV is the removal
of the legacy OSS driver codes that have been already disabled for a
long time.  This will bring a few trivial merge conflicts.

As new features in ASoC side, there are two things: a new AC97 bus
implementation and AMD Stony platform support.  Both include the
relevant changes shared with other subsystems, e.g. AC97 MFD changes
and DRM AMD changes.

Some other highlighted topics are:
- A bunch of USB-audio drivers got the hardening against the malicious
  device accesses with a new helper code for endpoint sanity check.
- Lots of cleanups for ASoC Intel platform code, including support for
  their open source audio firmware.
- Continued ASoC core componentization works.
- Support for scaling MCLK with sample rate in ASoC simple-card.
- Stabler PCM hot-unplug capability, especially for ASoC usages.

This is the bulk of GPIO changes for the v4.15 kernel cycle:

CORE:
- Fix the semantics of raw GPIO to actually be raw. No
  inversion semantics as before, but also no open draining,
  and allow the raw operations to affect lines used for
  interrupts as the caller supposedly knows what they are
  doing if they are getting the big hammer.

- Rewrote the __inner_function() notation calls to names that
  make more sense. I just find this kind of code disturbing.

- Drop the .irq_base() field from the gpiochip since now all
  IRQs are mapped dynamically. This is nice.

- Support for .get_multiple() in the core driver API. This
  allows us to read several GPIO lines with a single
  register read. This has high value for some usecases: it
  can be used to create oscilloscopes and signal analyzers
  and other things that rely on reading several lines at
  exactly the same instant. Also a generally nice
  optimization. This uses the new assign_bit() macro from
  the bitops lib that was ACKed by Andrew Morton and
  is implemented for two drivers, one of them being the
  generic MMIO driver so everyone using that will be able
  to benefit from this.

- Do not allow requests of Open Drain and Open Source
  setting of a GPIO line simultaneously. If the hardware
  actually supports enabling both at the same time the
  electrical result would be disastrous.

- A new interrupt chip core helper. This will be helpful
  to deal with "banked" GPIOs, which means GPIO controllers
  with several logical blocks of GPIO inside them. This
  is several gpiochips per device in the device model, in
  contrast to the case when there is a 1-to-1 relationship
  between a device and a gpiochip.

NEW DRIVERS:

- Maxim MAX3191x industrial serializer, a very interesting
  piece of professional I/O hardware.

- Uniphier GPIO driver. This is the GPIO block from the
  recent Socionext (ex Fujitsu and Panasonic) platform.

- Tegra 186 driver. This is based on the new banked GPIO
  infrastructure.

OTHER IMPROVEMENTS:

- Some documentation improvements.

- Wakeup support for the DesignWare DWAPB GPIO controller.

- Reset line support on the DesignWare DWAPB GPIO controller.

- Several non-critical bug fixes and improvements for the
  Broadcom BRCMSTB driver.

- Misc non-critical bug fixes like exotic errorpaths, removal
  of dead code etc.

- Explicit comments on fall-through switch() statements.

Device properties framework updates for v4.15-rc1

These make the fwnode_handle_get() function return a pointer to the
target fwnode object, which reflects the of_node_get() behavior, and
add a macro for iterating over graph endpoints (Sakari Ailus).

   (Arnd Bergmann, Dongjiu Geng, Jan Beulich).

 - Relocate the OPP (Operating Performance Points) framework to its
   own directory under drivers/ and add support for power domain
   performance states to it (Viresh Kumar).

 - Modify the PM core, the PCI bus type and the ACPI PM domain to
   support power management driver flags allowing device drivers to
   specify their capabilities and preferences regarding the handling
   of devices with enabled runtime PM during system suspend/resume
   and clean up that code somewhat (Rafael Wysocki, Ulf Hansson).

 - Add frequency-invariant accounting support to the task scheduler
   on ARM and ARM64 (Dietmar Eggemann).

 - Fix an issue in the system suspend core support code causing
   wakeup events detection to fail in some cases (Rajat Jain).

 - Fix the generic power domains (genpd) framework to prevent
   the PM core from using the direct-complete optimization with
   it as that is guaranteed to fail (Ulf Hansson).

 - Fix a minor issue in the cpuidle core and clean it up a bit
   (Gaurav Jindal, Nicholas Piggin).

 - Fix and clean up the intel_idle and ARM cpuidle drivers (Jason
   Baron, Len Brown, Leo Yan).

 - Fix a couple of minor issues in the OPP framework and clean it
   up (Arvind Yadav, Fabio Estevam, Sudeep Holla, Tobias Jordan).

 - Fix and clean up some cpufreq drivers and fix a minor issue in
   the cpufreq statistics code (Arvind Yadav, Bhumika Goyal, Fabio

regulator: Updates for v4.15

A very quiet release for regulator, there's some new device support in
existing drivers here and a few fixes but nothing in the core.

 - New device support for Allwinner AXP813, Dialog DA223/4/5 and
   Qualcomm PMI8994.

ASoC: Updates for v4.15

The biggest thing this release has been the conversion of the AC98 bus
to the driver model, that's been a long time coming so thanks to Robert
Jarzmik for his dedication there.  Due to there being some AC97 MFD
there's a few fairly large changes in input and the MFD layer, mainly to
the wm97xx driver.

There's also some drivers/drm changes to support the new AMD Stoney
platform, these are shared with the DRM subsystem and should be being
merged via both.

Within the subsystem the overwhelming bulk of the changes is in the
Intel drivers which continue to need lots of cleanups and fixes, this
release they've also gained support for their open source firmware.
There's also some large changs in the core as Morimoto-san continues to
mirror operations into the component level in preparation for conversion
of drivers to that.

 - The AC97 bus has finally caught up with the driver model thanks to
   some dedicated and persistent work from Robert Jarzmik.
 - Continued work from Morimoto-san on moving us towards being able to
   use components for everything.
 - Lots of cleanups for the Intel platform code, including support for
   their open source audio firmware.
 - Support for scaling MCLK with sample rate in simple-card.
 - Support for AMD Stoney platform.
