Merge tag 'sound-4.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound updates from Takashi Iwai:
 "It's been busy summer weeks and hence lots of changes, partly for a
  few new drivers and partly for a wide range of fixes.

  Here are highlights:

  ALSA Core:
   - Fix rawmidi buffer management, code cleanup / refactoring
   - Fix the SG-buffer page handling with incorrect fallback size
   - Fix the stall at virmidi trigger callback with a large buffer; also
     offloading and code-refactoring along with it
   - Various ALSA sequencer code cleanups

  ASoC:
   - Deploy the standard snd_pcm_stop_xrun() helper in several drivers
   - Support for providing name prefixes to generic component nodes
   - Quite a few fixes for DPCM as it gains a bit wider use and more
     robust testing
   - Generalization of the DIO2125 support to a simple amplifier driver
   - Accessory detection support for the audio graph card
   - DT support for PXA AC'97 devices
   - Quirks for a number of new x86 systems
   - Support for AM Logic Meson, Everest ES7154, Intel systems with
     RT5682, Qualcomm QDSP6 and WCD9335, Realtek RT5682 and TI TAS5707

  HD-audio:
   - Code refactoring in HD-audio ext codec codes to drop own classes;
     preliminary works for the upcoming legacy codec support
   - Generalized DRM audio component for the upcoming radeon / amdgpu
     support
   - Unification of mic mute-LED and GPIO support for various codecs
   - Further improvement of CA0132 codec support including Recon3D
   - Proper vga_switcheroo handling for AMD i-GPU
   - Update of model list in documentation
   - Fixups for another HP Spectre x360, Conexant codecs, power-save
     blacklist update

  USB-audio:
   - Fix the invalid sample rate setup with external clock
   - Support of UAC3 selector units and processing units
   - Basic UAC3 power-domain support
   - Support for Encore mDSD and Thesycon-based DSD devices
   - Preparation for future complete callback changes

  Firewire:
   - Add support for MOTU Traveler

  Misc:
   - The endianess notation fixes in various drivers
   - Add fall-through comment in lots of drivers
   - Various sparse warning fixes, e.g. about PCM format types"
