I guess this patchset should go better through sound git tree, so I'd
need ACKs for i915 changes in anyway.

Can i951 guys review these please?

Setting up the platform device and irqchip looks simple enough, so I'm
OK if i915 people think it being acceptable -- although it's a bit
unfortunate that we would have two distinct interfaces between video
and audio.

There are a few minor issues in some codes, and I'll comment in each
patch.


thanks,

Takashi
