Since we're talking slots / cards on a bus, I think the addressing
model would be useful here. So in the main controller node:
? ?#address-cells = <1>;
? ?#size-cells = <0>;

And then each slot would need a reg property and possibly unit address:

? slot {
? ? ? ?reg = <0>;
? ? ? ?...
? };

(unit addresses on the slots are only needed if they can't be
disambiguated by name, so not needed if you only have one slot).

Is the addressing model as described above needed in this case? The
address for a slot is not used by the controller driver code and is
just a virtual number. It would be sufficient to represent the nodes
representing the slots with a unique name.

Thanks,
Thomas.
