[alsa-devel] [PATCH 00/15] ASoC: SOF: Intel: HDaudio fixes and improvements

[Pierre-Louis Bossart]

This is unfortunately a rather large patchset tied to hardware
enablement. While productizing HDAudio+DMIC-based platforms, which is
a common design starting with CoffeLake platforms, the SOF team
encountered a combination of issues with host/link DMA coupling,
interrupt handling and other bits not getting properly cleared. The
patches in this series provide significant reliability and usage
improvements. They are viewed as mandatory for any product based on
HDaudio.

There will be a smaller series to fix HDaudio wake. It's almost ready
but didn't make the cut for this week and there's no reason to delay
reviews on the main changes further.

The remaining topics to complete are autodetection of the number of
microphones, for which an ACPI-based solution exists, and
autodetection of which platforms need to rely on a signed firmware,
for which DMI quirks will be required. This will be provided later in
July (after travel+vacation break for a number of contributors).
