No reg or anything else? Is that because it all goes thru the service
layer firmware? Just get the service layer driver to instantiate a
device for this driver or get rid of the 2 layers if that's all the
firmware interface does. DT is not a Linux driver instantiation
mechanism.

And build your dts files with "W=1" because there's an error in this
example.
