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

HP Spectre x360 convertible devices rely on a mixed SoundWire+DMIC
configuration which wasn't well supported. This lead to the discovery
that we missed the TGL_HDMI quirk on a number of Dell devices, the
addition of DMIC autodetection (based on NHLT tables), the addition of
new component strings needed by UCM, and work-arounds due to
problematic DSDT tables.

Changes since v1:
Rebase to remove first three patches already merged.
Fix allmodconfig issues (undeclared kernel parameter)

Bard Liao (1):
  ASoC: intel: sof_sdw: add trace for dai links

Guennadi Liakhovetski (1):
  ASoC: SOF: Intel: HDA: don't keep a temporary variable

Pierre-Louis Bossart (8):
  ASoC: Intel: sof_sdw: reorganize quirks by generation
  ASoC: Intel: sof-sdw: indent and add quirks consistently
  ASoC: Intel: sof_sdw: add quirk for HP Spectre x360 convertible
  ASoC: Intel: sof_sdw: add mic:dmic and cfg-mics component strings
  ASoC: Intel: soc-acpi: add ACPI matching table for HP Spectre x360
  ASoC: SOF: Intel: SoundWire: refine ACPI match
  ASoC: SOF: Intel: detect DMIC number in SoundWire mixed config
  ASoC: SOF: Intel: hda: add dev_dbg() when DMIC number is overridden

Rander Wang (1):
  ASoC: Intel: sof_sdw: detect DMIC number based on mach params
