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.
We use it register the driver for probe()ing. In the same way we do for the PMU and Regulators. All three of which actually belong to a different hardware block. Do you know of a better way to register those devices?
You've not identified which of the two cases above we're in... assuming it's a virtal device look at how the DT bindings for the other platforms are doing things.
