Hi,
The following series adds the core support to handle the recently updated
HDaudio multi-link support to hanlde non HDA links, like SoundWire/DMIC/SSP on
Intel platform.
For details, please see the first patch which documents the current mlink
support (introduced at Skylake) and the new extensions, arriving with LNL.
There is no change in functionality for existing HDA support, the extension is
backwards compatible with existing implementations.
Regards,
Peter
