Skylake onwards we support GTS capability and thus can report audio link time. This series adds support for parsing the capability and then reports link time.
The parsing of caps is made common and moved up from extended hda to hdac. The SKL driver and hdac extended core has been updated for this.
Mark, The update of the driver needs to update Skl driver, so if you can ACK the 2nd patch, it can go along with extended audio change thru ALSA tree.
Changes in v3: moved extended hda to hdac update SKL drv to use new hdac caps update patchset for HDA drv to use new caps parsing
Guneshwor Singh (2): ALSA - hda: Add support for parsing new HDA capabilities ALSA - hda: Add support for link audio time reporting
Vinod Koul (3): ALSA: hda - move bus_parse_capabilities to core ALSA: convert users to core bus_parse_capabilities ALSA - Ext hda: remove bus_parse_capabilities
