This patch series has only been tested on hardware with a single HDMI connector/pipe and additional work may be needed for newer machines with 2 connectors

I can merge the audio part and do cleanups later. This would be better than spinning forever in ML. It's a stand-alone driver, and people can test it out at least more easily. But still I need ACKs for the changes in drm/i915.
Daniel, Jani, could you guys take a look at the first two patches?
I know it's no ideal solution, and I'd love to avoid the double standards for audio-video communication, too. OTOH, it's a small portion and the API usage is pretty limited, hence we may unify / cleanup the interface later, too.
thanks,
Takashi
