It implements a series of improvements for: a) interrupt handling on Intel platforms in MSI mode b) race conditions on codec probe and enumeration c) suspend-resume issues (clock-stop mode not supported for now) d) underflow handling e) updates to the stream state machine which did not support valid ALSA transitions. These patches were tested extensively on 4 different platforms and are viewed as required for any sort of SoundWire-based product.
