[PATCH 00/14] ASoC: Intel/SOF: extend run-time driver selection to ACPI devices

[Pierre-Louis Bossart]

The module snd-intel-dspcfg, suggested by Jaroslav last year,
currently provide the means to select a PCI driver at run-time, based
on quirks, recommendations or user selection via a kernel
parameter. This capability removed a lot of confusions in
distributions and removed the need for recompilations to select legacy
HDaudio, SST or SOF drivers.

This patchset extends the concept to ACPI devices. This was driven by
the desire to at some point deprecate the Atom/SST driver for Baytrail
and Cherrytrail, which is no longer maintained by Intel. By having the
SOF driver enabled by distributions for Baytrail/Cherrytrail, we can
enable more end-user tests and make the transition easier for
distributions (likely in 2021 at this point).

This patchset provides the same solution for Broadwell, mainly to have
a single build for all Intel platforms. SOF on Broadwell remains an
option not recommended for distributions, as long as the 'catpt'
driver is maintained there is no burning desire to make SOF the
default on the three Broadwell-based platforms with the DSP
enabled.
