Merge series from Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>: The SoundWire BPT support will rely on the HDaudio DMA. This exposes a circular dependency module dependency which has to be resolved by splitting common parts used by HDaudio and SoundWire parts, and 'generic' parts used by HDaudio only. This patchset does not change any functionality, it just moves code around, exposes symbols that are used in the new module. The code has been in use for more than one kernel cycle already so it really shouldn't break any existing platforms. The main issue with such code moves is that it makes backports or fixes more complicated. That's the main reason why we held back these patches until we were reasonably confident on the maturity of MTL and LNL drivers.
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 reStructuredText 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.
