[alsa-devel] [PATCH 0/2] ALSA: HDAudio: enable dynamic selection between legacy and Skylake drivers

[Pierre-Louis Bossart]

This patchset depends on the "ASoC: Intel: Skylake: probe and Kconfig
simplifications" series.

Add the same logic based on PCI class/subclass/prog-if in the HDaudio
legacy probe, and add a module parameter to bypass or force the
automatic detection should it ever fail.

This patchset was tested on a SKL device with the DSP disabled and a
WHL device with the DSP enabled. All 6 combinations of
module parameters provided the expected behavior.

The SOF driver will use exactly the same mechanism, and add a mutual
exclusion with the Skylake/SST driver to avoid having 3 drivers for
the same PCI ID. Two is complicated enough.

Pierre-Louis Bossart (2):
  ALSA: HD-Audio: SKL+: abort probe if DSP is present and Skylake driver
    selected
  ALSA: HD-Audio: SKL+: force HDaudio legacy or SKL+ driver selection
