I fully agree and I actually made that change at some point before
sending v1. Unfortunately, it doesn't work: The node name "glink-edge"
is already reserved by qcom,glink-edge.yaml. While it's very similar it
has some subtle differences to glink-rpm-edge.yaml. For example, there
is no qcom,remote-pid in the RPM variant which is required by the normal
glink-edge.

Would "glink-rpm-edge" sound better?

Thanks,
