Merge tag 'sound-5.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound updates from Takashi Iwai:
 "As the diffstat shows we've had again a lot of works done for this
  cycle: the majority of changes are the continued componentization and
  code refactoring in ASoC, the tree-wide PCM API updates and cleanups
  and SOF updates while a few ASoC driver updates are seen, too.

  Here we go, some highlights:

  Core:
   - Finally y2038 support landed to ALSA ABI; some ioctls have been
     extended and lots of tricks were applied
   - Applying the new managed PCM buffer API to all drivers; the API
     itself was already merged in 5.5
   - The already deprecated dimension support in ALSA control API is
     dropped completely now
   - Verification of ALSA control elements to catch API misuses

  ASoC:
   - Further code refactorings and moving things to the component level
   - Lots of updates and improvements on SOF / Intel drivers; now
     including common HDMI driver and SoundWire support
   - New driver support for Ingenic JZ4770, Mediatek MT6660, Qualcomm
     WCD934x and WSA881x, and Realtek RT700, RT711, RT715, RT1011,
     RT1015 and RT1308

  HD-audio:
   - Improved ring-buffer communications using waitqueue
   - Drop the superfluous buffer preallocation on x86

  Others:
   - Many code cleanups, mostly constifications over the whole tree
   - USB-audio: quirks for MOTU, Corsair Virtuoso, Line6 Helix
   - FireWire: code refactoring for oxfw and dice drivers"
