[PATCH 00/20] ALSA/ASoC/SOF/Intel: improve support for ES8336-based platforms

[Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>]

This patchset adds a number of improvements for ES8336-based Intel
platforms, which are not well supported at all in Linux. Since
Christmas 2021, we've seen dozens of reports of broken audio [1].

The fundamental problem is that those platforms were built for Windows
but using an I2S codec - instead of the HDaudio traditional
solution. As a result, we are missing all the usual information needed
to configure the audio card (which I2S, what configuration, DMICs or
not, etc). The situation is similar to Baytrail with all possible
permutations enabled.

Some of the information can be discovered by checking the contents of
the 'NHLT' ACPI table. This helps discover at run-time which SSP to
use, and the number of microphones present. This NHLT-based solution
helps remove quirks that were added earlier.

Unfortunately, there are still a number of platform properties that
are not described by ACPI, just as GPIOs used for speakers, jack
detection inversion, etc. For some case, quirks are still provided in
the machine drivers.

Additional work will likely be needed, e.g. to detect which MCLK needs
to be used, refine the UCM settings, add the ES8326 codec driver, but
this is a first-step towards an 'out of the box' experience on Intel
platforms.

This patchset touches the sound/hda/intel-nhlt parts but should IMHO
be merged in the ASoC tree.

I would like to acknowledge the help of Nikolai Kostrigin, Mauro
Carvalho Chehab, Huajun Li, David Yang (@yangxiaohua2009) and other
GitHub testers.
