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.
