If there is a 'reg' property in the child, I guess we should also
document a #address-cells/#size-cells value for the parent.

Can you give an example of a multi-port serial device we support?

A 16550 DUART chip. Not sure if we have any bindings for one though.
Maybe the chip would be the parent node containing 2 child ns16550
nodes.

I was expecting that we already need a device node per port anyway,
to make the console work.

Yes, good point. I think I'll just drop it for now.
