The CS42L42 has a Soundwire interface for control and audio. This chain of patches adds support for this.
Patches #1 .. #10 split out various changes to the existing code that are needed for adding Soundwire. These are mostly around clocking and supporting the separate probe and enumeration stages in Soundwire.
Patches #11 and #12 actually add the Soundwire handling.
