BTW this depends on the series "[PATCH v2 00/18] ASoC: SOF: Intel: hda-mlink: HDaudio multi-link extension update" applied yesterday by Mark. It'd be really nice if we can have this in 6.4-rc1 to continue adding the rest of the Lunar Lake patches. We tried to limit the number of changes impacting both ASoC and SoundWire subsystems but there's mechanically 2 merges needed (ASoC -> SoundWire for the hda-mlink dependency and SoundWire->ASoC for the interface changes below). > >> registers are now split in 3 (SHIM, IP, SHIM vendor-specific), with some >> parts also moved to the HDaudio Extended Multi link structures.
