I think some consensus has been achieved for describing i2c busses and
their attached devices, but I don't think booting-without-of.txt has
been updated with the details yet.  I need to look into that more.

I don't think anyone has tackled CAN.  Best bet is to draft a tree in
the way you think it should be described and post it to the list.
That will give a starting point for us to discuss it and come to
consensus.

Cheers,
