Ah, I see.

I think I suggested it before, but anyway:

how about you write

	aliases {
		foo = "/the/path/to/foo";
	};

and then you can use  &foo  in the rest of the DTS to refer to the
phandle (or path string, as it turns out :-) ) of the node?  I.e.,
use the aliases node to _generate_ aliases.

Seems simpler than the current thing to me.
