I presume this will result in a strcmp in some client driver?

When we're registering the rpmsg device, as part of handling of an
arriving "open request", we do look for an of_node with matching
qcom,glink-channels and if one is found we point the dev->of_node of the
new device to this node.

So I would suggest that you, in your client driver, use this to decide
which instance you're on; regardless if you're using compatible based
driver matching.

Does this work for you?
