Oh, I don't think we're claiming anything is impossible here :) It's more
that we will probably want to make some changes to the device model to allow,
for example, a device to be associated with multiple buses of potentially
different types.

Step one is to get the DT binding sorted, then we can try and get Linux to
make use of it. This goes hand-in-hand with the IOMMU discussion going on
here:

which is one of the issues that is hitting us right now.

Cheers,
