One of two things is wrong here.  Either you've not provided any
information about the hardware so the driver won't be able to work out
what to talk to or you've not provided any data so you're registering a
purely virtual Linux-internal device via the device tree.

Once more, the idea here is to describe the hardware not to dump Linux's
internal data structures into the device tree.
