Why is this in a reg?
This is to identify which type of dsp(Audio/Modem/Sensor/Compute) it is,
This information is used to create device nodes for user-space access.
But it does not represent FastRPC's address on the rpmsg bus. How about
replacing it with a "label" (or "qcom,domain" perhaps?) of type string?
Yes, we could replace reg with label in this case. I don't have any
particular preference TBH.
I did try to something similar to "qcom,domain" for apr and Rob H
suggested to use reg instead during review!
