Why is this all being open coded in an individual driver (we already
know about and manage all these dependencies in the core...)?  If we're
going to do this I'd expect the interface for specifying DT nodes to the
core to be changed to support this.

Are you thinking of changing drivers to acquire their resources
through Arnd's devm_probe (only that the resource table would have to
be in struct device_driver)?

Sounds like lots of fun, but that means that any given machine will
get ordered probe only after all the drivers it uses have been moved
to the new declarative API.

TBH, that seems really far away.
