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

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.

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 GPIO changes for the v3.16 series:

- We are finalizing and fixing up the gpiochip irqchip helpers
  bringing a helpful irqchip implementation into the gpiolib
  core and avoiding duplicate code and, more importantly,
  duplicate bug fixes:

  - Support for using the helpers with threaded interrupt
    handlers as used on sleeping GPIO-irqchips

  - Do not set up hardware triggers for edges or levels if
    the default IRQ type is IRQ_TYPE_NONE - some drivers
    would exploit the fact that you could get default
    initialization of the IRQ type from the core at probe()
    but if no default type is set up from the helper, we
    should not call the driver to configure anything. Wait
    until a consumer requests the interrupt instead.

  - Make the irqchip helpers put the GPIO irqs into their
    own lock class. The GPIO irqchips can often emit
    (harmless, but annoying) lockdep warnings about recursions
    when they are in fact just cascaded IRQs. By putting
    them into their own lock class we help the lockdep core
    to keep track of things.

  - Switch the tc3589x GPIO expanders to use the irqchip
    helpers

  - Switch the OMAP GPIO driver to use the irqchip helpers

  - Add some documentation for the irqchip helpers

  - select IRQ_DOMAIN when using the helpers since some
    platforms may not be using this by default and it's a
    strict dependency.

- Continued GPIO descriptor refactoring:

  - Remove the one instance of gpio_to_desc() from the
    device tree code, making the OF GPIO code use GPIO
    descriptors only.

  - Introduce gpiod_get_optional() and
    gpiod_get_optional_index() akin to the similar
    regulator functions for cases where the use of GPIO
    is optional and not strictly required.

  - Make of_get_named_gpiod_flags() private - we do not
    want to unnecessarily expose APIs to drivers that
    make the gpiolib harder than necessary to maintain
    and refactor. Privatize this function.

- Support "-gpio" suffix for the OF GPIO retrieveal path.
  We used to look for "foo-gpios" or just "gpios" in device
  tree nodes, but it turns out that some drivers with a
  single GPIO line will just state "foo-gpio" (singularis).
  Sigh. Support this with a fallback looking for it, as
  this simplifies driver code and handles it in core code.

- Switch the ACPI GPIO core to fetch GPIOs with the
  *_cansleep function variants as the GPIO operation
  region handler can sleep, and shall be able to handle
  gpiochips that sleep.

- Tons of cleanups and janitorial work from Jingoo Han,
  Axel Lin, Javier Martinez Canillas and Abdoulaye Berthe.
  Notably Jingoo cut off a ton of pointless OOM messages.

- Incremental development and fixes for various drivers,
  nothing really special here.

This is the 3.12.21 stable release
