Merge series from 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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
