Hi,
Changes since v1:
- Rename hda_bus_ml_get_capabilities() to hda_bus_ml_init() - patch 06/18
- Rename check_power_active() to check_sublink_power() and the parameter from
enable to enabled - patch 08/18
Not changed: the poll timeout implementation for now, as Pierre mentioned it can
be done at a later time.
Cover letter:
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
