I mean do you see any problem with giving Linux knowledge of
the -slave name?

p.s.

Actually, we can stay with status = ".." property, and if
things ever change, it's always driver's duty to check for
of_device_is_available(), and so the driver can simply check
for
if (!strcmp(status, "disabled on core"))
	probe_children_only().
