This document really needs quite a bit of fleshing out but I'm not sure
that should be a blocker for the series as a whole especially given that
English is not your native language - we can build out later.  I think
based on what I'm understanding here I like what I'm seeing.  It'd be
good to get some confirmation from the people with more of_graph
knowledge that this is a good usage.

One thing I'm not 100% clear on here is why it has to be a CPU DAI (I'm
guessing just one of them though the above says ports as an option?)
that creates the card?  Is there a concrete reason for that or is it
just being defined as good pracctice?
