sound updates for 3.16-rc1

At this time, majority of changes come from ASoC world while we got a
few new drivers in other places for FireWire and USB.  There have been
lots of ASoC core cleanups / refactoring, but very little visible to
external users.

ASoC
- Support for specifying aux CODECs in DT
- Removal of the deprecated mux and enum macros
- More moves towards full componentisation
- Removal of some unused I/O code
- Lots of cleanups, fixes and enhancements to the davinci, Freescale,
  Haswell and Realtek drivers
- Several drivers exposed directly in Kconfig for use with simple-card
- GPIO descriptor support for jacks
- More updates and fixes to the Freescale SSI, Intel and rsnd drivers
- New drivers for Cirrus CS42L56, Realtek RT5639, RT5642 and RT5651 and
  ST STA350, Analog Devices ADAU1361, ADAU1381, ADAU1761 and ADAU1781,
  and Realtek RT5677

HD-audio:
- Clean up Dell headset quirks
- Noise fixes for Dell and Sony laptops
- Thinkpad T440 dock fix
- Realtek codec updates (ALC293,ALC233,ALC3235)
- Tegra HD-audio HDMI support

FireWire-audio:
- FireWire audio stack enhancement (AMDTP, MIDI), support for incoming
  isochronous stream and duplex streams with timestamp synchronization
- BeBoB-based devices support
- Fireworks-based device support

USB-audio:
- Behringer BCD2000 USB device support

Misc:
- Clean up of a few old drivers, atmel, fm801, etc

DeviceTree for 3.16:
- Another round of clean-up of FDT related code in architecture code.
  This removes knowledge of internal FDT details from most architectures
  except powerpc.
- Conversion of kernel's custom FDT parsing code to use libfdt.
- DT based initialization for generic serial earlycon. The introduction
  of generic serial earlycon support went in thru tty tree.
- Improve the platform device naming for DT probed devices to ensure
  unique naming and use parent names instead of a global index.
- Fix a race condition in of_update_property.
- Unify the various linker section OF match tables and fix several
  function prototype errors.
- Update platform_get_irq_byname to work in deferred probe cases.
- 2 binding doc updates

At over 200 commits, covering almost all supported architectures, this
was a pretty active cycle for KVM.  Changes include:

- a lot of s390 changes: optimizations, support for migration,
  GDB support and more

- ARM changes are pretty small: support for the PSCI 0.2 hypercall
  interface on both the guest and the host (the latter acked by Catalin)

- initial POWER8 and little-endian host support

- support for running u-boot on embedded POWER targets

- pretty large changes to MIPS too, completing the userspace interface
  and improving the handling of virtualized timer hardware

- for x86, a larger set of changes is scheduled for 3.17.  Still,
  we have a few emulator bugfixes and support for running nested
  fully-virtualized Xen guests (para-virtualized Xen guests have
  always worked).  And some optimizations too.

The only missing architecture here is ia64.  It's not a coincidence
that support for KVM on ia64 is scheduled for removal in 3.17.

ACPI and power management updates for 3.16-rc1

 - ACPICA update to upstream version 20140424.  That includes a
   number of fixes and improvements related to things like GPE
   handling, table loading, headers, memory mapping and unmapping,
   DSDT/SSDT overriding, and the Unload() operator.  The acpidump
   utility from upstream ACPICA is included too.  From Bob Moore,
   Lv Zheng, David Box, David Binderman, and Colin Ian King.

 - Fixes and cleanups related to ACPI video and backlight interfaces
   from Hans de Goede.  That includes blacklist entries for some new
   machines and using native backlight by default.

 - ACPI device enumeration changes to create platform devices
   rather than PNP devices for ACPI device objects with _HID by
   default.  PNP devices will still be created for the ACPI device
   object with device IDs corresponding to real PNP devices, so
   that change should not break things left and right, and we're
   expecting to see more and more ACPI-enumerated platform devices
   in the future.  From Zhang Rui and Rafael J Wysocki.

 - Updates for the ACPI LPSS (Low-Power Subsystem) driver allowing
   it to handle system suspend/resume on Asus T100 correctly.
   From Heikki Krogerus and Rafael J Wysocki.

 - PM core update introducing a mechanism to allow runtime-suspended
   devices to stay suspended over system suspend/resume transitions
   if certain additional conditions related to coordination within
   device hierarchy are met.  Related PM documentation update and
   ACPI PM domain support for the new feature.  From Rafael J Wysocki.

 - Fixes and improvements related to the "freeze" sleep state. They
   affect several places including cpuidle, PM core, ACPI core, and
   the ACPI battery driver.  From Rafael J Wysocki and Zhang Rui.

 - Miscellaneous fixes and updates of the ACPI core from Aaron Lu,
   Bjørn Mork, Hanjun Guo, Lan Tianyu, and Rafael J Wysocki.

 - Fixes and cleanups for the ACPI processor and ACPI PAD (Processor
   Aggregator Device) drivers from Baoquan He, Manuel Schölling,
   Tony Camuso, and Toshi Kani.

 - System suspend/resume optimization in the ACPI battery driver from
   Lan Tianyu.

 - OPP (Operating Performance Points) subsystem updates from
   Chander Kashyap, Mark Brown, and Nishanth Menon.

 - cpufreq core fixes, updates and cleanups from Srivatsa S Bhat,
   Stratos Karafotis, and Viresh Kumar.

 - Updates, fixes and cleanups for the Tegra, powernow-k8, imx6q,
   s5pv210, nforce2, and powernv cpufreq drivers from Brian Norris,
   Jingoo Han, Paul Bolle, Philipp Zabel, Stratos Karafotis, and
   Viresh Kumar.

 - intel_pstate driver fixes and cleanups from Dirk Brandewie,
   Doug Smythies, and Stratos Karafotis.

 - Enabling the big.LITTLE cpufreq driver on arm64 from Mark Brown.

 - Fix for the cpuidle menu governor from Chander Kashyap.

 - New ARM clps711x cpuidle driver from Alexander Shiyan.

 - Hibernate core fixes and cleanups from Chen Gang, Dan Carpenter,
   Fabian Frederick, Pali Rohár, and Sebastian Capella.

 - Intel RAPL (Running Average Power Limit) driver updates from
   Jacob Pan.

 - PNP subsystem updates from Bjorn Helgaas and Fabian Frederick.

 - devfreq core updates from Chanwoo Choi and Paul Bolle.

 - devfreq updates for exynos4 and exynos5 from Chanwoo Choi and
   Bartlomiej Zolnierkiewicz.

 - turbostat tool fix from Jean Delvare.

 - cpupower tool updates from Prarit Bhargava, Ramkumar Ramachandra
   and Thomas Renninger.

 - New ACPI ec_access.c tool for poking at the EC in a safe way
   from Thomas Renninger.

Final power management fixes for 3.15

 - Taking non-idle time into account when calculating core busy
   time was a mistake and led to a performance regression.  Since
   the problem it was supposed to address is now taken care of in
   a different way, we don't need to do it any more, so drop the
   non-idle time tracking from intel_pstate.  Dirk Brandewie.

 - Changing to fixed point math throughout the busy calculation
   introduced rounding errors that adversely affect the accuracy
   of intel_pstate's computations.  Fix from Dirk Brandewie.

 - The PID controller algorithm used by intel_pstate assumes that
   the time interval between two adjacent samples will always be the
   same which is not the case for deferable timers (used by
   intel_pstate) when the system is idle. This leads to inaccurate
   predictions and artificially increases convergence times for
   the minimum P-state.  Fix from Dirk Brandewie.

 - intel_pstate carries out computations using 32-bit variables
   that may overflow for large enough values of APERF/MPERF.  Switch
   to using 64-bit variables for computations, from Doug Smythies.

regulator: Updates for v3.16

The bulk of the changes for this release are a few new drivers however
there are a couple of noticable core changes and the usual stream of
cleanups and fixes:

 - Move disable of unused regulators later in init so it comes after
   deferred probe has iterated making startup smoother.
 - Fixes reference counting of the DT nodes for constraints from Charles
   Keepax.  This has little practical impact since all real users of
   the regulator bindings use FDT which doesn't need the reference
   counting.
 - Lots of cleanups, especially to the Samsung drivers.
 - Support for Linear Technologies LTC3589, Texas Instruments TPS658640
   and X-Powers AXP20x.

ASoC: Final updates for v3.16

A few more updates from the last week of development, nothing too
exciting.  Highlights include:

- GPIO descriptor support for jacks
- More updates and fixes to the Freescale SSI, Intel and rsnd drivers.
- New drivers for Analog Devices ADAU1361, ADAU1381, ADAU1761 and
  ADAU1781, and Realtek RT5677.

sound fixes for 3.15-final

A few addition of HD-audio fixups for ALC260 and AD1986A codecs.
All marked as stable fixes.

The fixes are pretty local and they are old machines, so quite safe
to apply.

This is the bulk of pin control changes for the v3.16
development cycle:

- Antoine Tenart made the get_group_pins() vtable entry
  optional.

- Antoine also provides an entirely new driver for the
  Marvell Berlin SoC. This is unrelated to the existing
  MVEBU hardware driver and warrants its own separate
  driver.

- Reflected from the GPIO subsystem there is a number of
  refactorings to make pin control drivers with gpiochips
  use the new gpiolib irqchip helpers. The following
  drivers were converted to use the new infrastructure:

  - ST Microelectronics STiH416 and friends

  - The Atmel AT91

  - The CSR SiRF (Prima2)

  - The Qualcomm MSM series

- Massive improvements in the Qualcomm MSM driver from
  Bjorn Andersson, Andy Gross and Kumar Gala. Among those
  new support for the IPQ8064 and MSM8x74 SoC variants.

- Support for the Freescale i.MX6 SoloX SoC variant.

- Massive improvements in the Allwinner sunxi driver from
  Boris Brezillon, Maxime Ripard and Chen-Yu Tsai.

- Renesas PFC updates from Laurent Pinchart, Kuninori
  Morimoto, Wolfram Sang and Magnus Damm.

- Cleanups and refactorings of the nVidia Tegra driver from
  Stepgen Warren.

- The Exynos driver now supports the Exynos3250 SoC.

- Intel BayTrail updates from Jin Yao, Mika Westerberg.

- The MVEBU driver now supports the Orion5x SoC
  variants, which is part of the effort of getting rid of
  the old Marvell kludges in arch/arm/mach-orion5x

- Rockchip driver updates from Heiko Stuebner.

- A ton of cleanups and janitorial patches from Axel Lin.

- Some minor fixes and improvements here and there.

Staging driver patches for 3.16-rc1

Here is the big staging driver pull request for 3.16-rc1.

Lots of stuff here, tons of cleanup patches, a few new drivers, and some
removed as well, but I think we are still adding a few thousand more
lines than we remove, due to the new drivers being bigger than the ones
deleted.

One notible bit of work did stand out, Jes Sorensen has gone on a tear,
fixing up a wireless driver to be "more sane" than it originally was
from the vendor, with over 500 patches merged here.  Good stuff, and a
number of users laptops are better off for it.

All of this has been in linux-next for a while.
