This RFC is the companion of the other RFC 'soundwire: intel: simplify DAI/PDI handling'. Our purpose at this point is to gather feedback on the interfaces between the Intel SOF parts and the SoundWire code. The suggested solution is a simple init/release inserted at probe/remove and resume/suspend, as well as two callbacks for the SOF driver to generate IPC configurations with the firmware. That level of separation completely hides the details of the SoundWire DAIs and will allow for 'transparent' multi-cpu DAI support, which will be handled in the machine driver and the soundwire DAIs. This solution was tested on IceLake and CometLake, and captures the feedback from SOF contributors on an initial integration that was deemed too complicated (and rightly so).
