It's true that there's something executing elsewhere in the SoC
acting upon the request written to the RPM memory region.

But for me the phrasing "over IPC" applies much more to the SMD/GLINK
variant than to this. So I would prefer to just name this
"qcom,rpm.yaml" and omit the "over IPC" phrasing.


Binding looks good to me.
