Merge tag 'sound-3.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound updates from Takashi Iwai:
 "In this batch, you can find lots of cleanups through the whole
  subsystem, as our good New Year's resolution.  Lots of LOCs and
  commits are about LINE6 driver that was promoted finally from staging
  tree, and as usual, there've been widely spread ASoC changes.

  Here some highlights:

  ALSA core changes
   - Embedding struct device into ALSA core structures
   - sequencer core cleanups / fixes
   - PCM msbits constraints cleanups / fixes
   - New SNDRV_PCM_TRIGGER_DRAIN command
   - PCM kerneldoc fixes, header cleanups
   - PCM code cleanups using more standard codes
   - Control notification ID fixes

  Driver cleanups
   - Cleanups of PCI PM callbacks
   - Timer helper usages cleanups
   - Simplification (e.g. argument reduction) of many driver codes

  HD-audio
   - Hotkey and LED support on HP laptops with Realtek codecs
   - Dock station support on HP laptops
   - Toshiba Satellite S50D fixup
   - Enhanced wallclock timestamp handling for HD-audio
   - Componentization to simplify the linkage between i915 and hd-audio
     drivers for Intel HDMI/DP

  USB-audio
   - Akai MPC Element support
   - Enhanced timestamp handling

  ASoC
   - Lots of refactoringin ASoC core, moving drivers to more data driven
     initialization and rationalizing a lot of DAPM usage
   - Much improved handling of CDCLK clocks on Samsung I2S controllers
   - Lots of driver specific cleanups and feature improvements
   - CODEC support for TI PCM514x and TLV320AIC3104 devices
   - Board support for Tegra systems with Realtek RT5677
   - New driver for Maxim max98357a
   - More enhancements / fixes for Intel SST driver

  Others
   - Promotion of LINE6 driver from staging along with lots of rewrites
     and cleanups
   - DT support for old non-ASoC atmel driver
   - oxygen cleanups, XIO2001 init, Studio Evolution SE6x support
   - Emu8000 DRAM size detection fix on ISA(!!) AWE64 boards
   - A few more ak411x fixes for ice1724 boards"

-menuconfig LINE6_USB
-	tristate "Line6 USB support"
-	depends on USB && SND
-	select SND_RAWMIDI
-	select SND_PCM
-	help
-	  This is a driver for the guitar amp, cab, and effects modeller
-	  PODxt Pro by Line6 (and similar devices), supporting the
-	  following features:
-	    * Reading/writing individual parameters
-	    * Reading/writing complete channel, effects setup, and amp
-	      setup data
-	    * Channel switching
-	    * Virtual MIDI interface
-	    * Tuner access
-	    * Playback/capture/mixer device for any ALSA-compatible PCM
-	      audio application
-	    * Signal routing (record clean/processed guitar signal,
-	      re-amping)
-
-	  Preliminary support for the Variax Workbench and TonePort
-	  devices is included.

-config LINE6_USB_IMPULSE_RESPONSE
-	bool "measure impulse response"
-	default n
-	help
-	  Say Y here to add code to measure the impulse response of a Line6
-	  device. This is more accurate than user-space methods since it
-	  bypasses any PCM data buffering (e.g., by ALSA or jack). This is
-	  useful for assessing the performance of new devices, but is not
-	  required for normal operation.
-
-	  If unsure, say N.

-	PCM mode bits.
-
-	There are several features of the Line6 USB driver which require PCM
-	data to be exchanged with the device:
-	*) PCM playback and capture via ALSA
-	*) software monitoring (for devices without hardware monitoring)
-	*) optional impulse response measurement
-	However, from the device's point of view, there is just a single
-	capture and playback stream, which must be shared between these
-	subsystems. It is therefore necessary to maintain the state of the
-	subsystems with respect to PCM usage. We define several constants of
-	the form LINE6_BIT_PCM_<subsystem>_<direction>_<resource> with the
-	following meanings:
-	*) <subsystem> is one of
-	-) ALSA: PCM playback and capture via ALSA
-	-) MONITOR: software monitoring
-	-) IMPULSE: optional impulse response measurement
-	*) <direction> is one of
-	-) PLAYBACK: audio output (from host to device)
-	-) CAPTURE: audio input (from device to host)
-	*) <resource> is one of
-	-) BUFFER: buffer required by PCM data stream
-	-) STREAM: actual PCM data stream
-
-	The subsystems call line6_pcm_acquire() to acquire the (shared)
-	resources needed for a particular operation (e.g., allocate the buffer
-	for ALSA playback or start the capture stream for software monitoring).
-	When a resource is no longer needed, it is released by calling
-	line6_pcm_release(). Buffer allocation and stream startup are handled
