Just a quick question as I was trying to understand the code:
aud_sample_rate seems only set and get on the i915 side, never on the hda side.
In short, why is this variable here, and not in e g, as a single integer in the intel_digital_port struct?
That way we also avoid the possibility of MAX_PORTS becoming out of sync with the i915 side.
Put it in struct i915_audio_component just because it is audio related and easy for management.
It seems to put it in intel_digital_port will be easier.
Let's hear the gfx team's comments.
