Merge tag 'sound-5.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound updates from Takashi Iwai:
 "It was another busy development cycle, and the majority of changes are
  found in ASoC side. Below are Some highlights.

  ASoC core:
   - Lots of core cleanups and refactorings, still on-going work by
     Morimoto-san

  ASoC drivers:
   - Continued work on cleaning up and improving the Intel SOF stuff,
     along with new platform support including SoundWire

   - Fixes to make the Marvell SSPA driver work upstream

   - Support for AMD Renoir ACP, Dialog DA7212, Freescale EASRC and
     i.MX8M, Intel Elkhard Lake, Maxim MAX98390, Nuvoton NAU8812 and
     NAU8814 and Realtek RT1016.

  USB-audio:
   - Improvement for sync and implicit feedback streams with the more
     accurate frame size calculation and full-duplex support

   - Support for RME Babyface Pro and Prioneer DJ DJM

  HD-audio:
   - Fixes for Mic mute LED on HP machines

   - Re-enable support of Intel SST driver for SKL/KBL platforms

  FireWire:
   - Lots of refactoring, add support for RME FireFace and MOTU
     UltraLite-mk3"

-Dai-link subnode properties and subnodes:
-
-If dai-link subnode is omitted and the subnode properties are directly
-under "sound"-node the subnode property and subnode names have to be
-prefixed with "simple-audio-card,"-prefix.
-
-Required dai-link subnodes:
-
-- cpu					: CPU   sub-node
-- codec					: CODEC sub-node
-
-Optional dai-link subnode properties:
-
-- format				: CPU/CODEC common audio format.
-					  "i2s", "right_j", "left_j" , "dsp_a"
-					  "dsp_b", "ac97", "pdm", "msb", "lsb"
-- frame-master				: Indicates dai-link frame master.
-					  phandle to a cpu or codec subnode.
-- bitclock-master			: Indicates dai-link bit clock master.
-					  phandle to a cpu or codec subnode.
-- bitclock-inversion			: bool property. Add this if the
-					  dai-link uses bit clock inversion.
-- frame-inversion			: bool property. Add this if the
-					  dai-link uses frame clock inversion.
-- mclk-fs             			: Multiplication factor between stream
-					  rate and codec mclk, applied only for
-					  the dai-link.
-
-For backward compatibility the frame-master and bitclock-master
-properties can be used as booleans in codec subnode to indicate if the
-codec is the dai-link frame or bit clock master. In this case there
-should be no dai-link node, the same properties should not be present
-at sound-node level, and the bitclock-inversion and frame-inversion
-properties should also be placed in the codec node if needed.
-
-Required CPU/CODEC subnodes properties:
-
-- sound-dai				: phandle and port of CPU/CODEC
-
-Optional CPU/CODEC subnodes properties:
-
-- dai-tdm-slot-num			: Please refer to tdm-slot.txt.
-- dai-tdm-slot-width			: Please refer to tdm-slot.txt.
-- clocks / system-clock-frequency	: specify subnode's clock if needed.
-					  it can be specified via "clocks" if system has
-					  clock node (= common clock), or "system-clock-frequency"
-					  (if system doens't support common clock)
-					  If a clock is specified, it is
-					  enabled with clk_prepare_enable()
-					  in dai startup() and disabled with
-					  clk_disable_unprepare() in dai
-					  shutdown().
-					  If a clock is specified and a
-					  multiplication factor is given with
-					  mclk-fs, the clock will be set to the
-					  calculated mclk frequency when the
-					  stream starts.
-- system-clock-direction-out		: specifies clock direction as 'out' on
-					  initialization. It is useful for some aCPUs with
-					  fixed clocks.
