Subject: [PATCH v2 00/26] ASoC/soundwire: add support for ACE2.x

This series uses the abstraction added in past kernel cycles to provide
support for the ACE2.x integration. The existing SHIM and Cadence
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.

v2:
 - Some cleanup for free, trigger, hw_params callbacks before introducing
   ACE2.x callbacks.

Pierre-Louis Bossart (26):
  ASoC: SOF: Intel: shim: add enum for ACE 2.0 IP used in LunarLake
