Merge series "ASoC: SOF: Intel: add SoundWire support" from Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>:

This patchset provides the support for SoundWire support on Intel
CometLake, IcelLake and TigerLake RVP platforms and form-factor
devices to be released 'soon'.

The bulk of the code is about detecting a valid SoundWire
configuration from ACPI, and implementing the interfaces suggested in
'[PATCH 0/8] soundwire: remove platform devices, add SOF interfaces'
for interrupts, PCI wakes and clock-stop configurations.

Since that SoundWire series will not be in 5.7, the build support for
SOF w/ SoundWire is not provided for now, and fall-back functions will
be used. This code is tested on a daily basis in the SOF tree and is
not expected to change in significant ways.

Changes since v2:
Corrected error in ACPI table (thanks Amadeusz)
Added patch 11 to add reset cycle required on some SoundWire platforms

Bard Liao (1):
  ASoC: SOF: Intel: hda: merge IPC, stream and SoundWire interrupt
    handlers

Pierre-Louis Bossart (8):
  ASoC: soc-acpi: expand description of _ADR-based devices
  ASoC: SOF: Intel: add SoundWire configuration interface
  ASoC: SOF: IPC: dai-intel: move ALH declarations in header file
  ASoC: SOF: Intel: hda: add SoundWire stream config/free callbacks
  ASoC: SOF: Intel: hda: initial SoundWire machine driver autodetect
  ASoC: SOF: Intel: hda: disable SoundWire interrupts on suspend
  ASoC: SOF: Intel: hda: add parameter to control SoundWire clock stop
    quirks
  ASoC: SOF: Intel: hda-ctrl: add reset cycle before parsing
    capabilities

Rander Wang (2):
  ASoC: SOF: Intel: hda: add WAKEEN interrupt support for SoundWire
  Asoc: SOF: Intel: hda: check SoundWire wakeen interrupt in irq thread
