[PATCH v2 0/3] ALSA: hda: add link_power op to hdac_bus_ops

[Kai Vehmanen]

Here's the 2nd iteration of the patch to improve link management
granularity between controllers using HDA extended bus and HDA
codec drivers.

Based on feedback to V1, this now adds a new link_power op.
This allows to decouple HDA codec drivers from the hdac_ext core.

I also included two patches to SOF to show how this interface is
used in SOF.

  ASoC: SOF: Intel: hda: use hdac_ext fine-grained link management
