Takashi,
I just realized I did something silly and didn't send you all the changes in this patch. I'm adding some more useful stuff to the proc output and I'll send another patch shortly which contains all the changes. This one can be disregarded for now.
Thanks, -Andrew

This adds additional pincaps which were not previously output. Also, Vref capabilities are output per-pin along with the current Vref pinctl setting if the NID supports Vref. Also added: processing widgets and proccaps, as well as processing coefficient and coefficient index from the Realtek Define Registers per the ALC883 datasheet.

Did you check whether this doesn't break Claudio's codecgraph parser? If it's OK, I'd like to apply it, of course...
