That wasn't what I was implying ... all the devices hooked
up to a given chipselect should be viewed as a single (albeit
composite) child node.

Now, the driver for that child node may want to expose lots
of substructure. But that's no different from any other
complex device, whose protocol happens to embed some notion
of component addressing.

It's just that in the case I mentioned, that addressing is
a bit more externally visible than it is in some other cases.
