ACE2..?
Not sure I get the comment, this refers to the IP version.
ACE 2.0 IP used in LunarLake, x refers to future TDB versions.
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. Nothing fundamentally different except for the register map.
This series only provides the basic mechanisms to expose SoundWire-based DAIs. The PCI parts and DSP management will be contributed later, and the DAI ops are now empty as well.
The change is mainly on SoundWire. It would be better to go through SoundWire tree.
