Why is this RFC? Do you expect DT maintainers review or not? Maybe there
is no point for us to review something which is not going to be applied?

You should include ethernet controller schema.

4-space indentation for DTS, please.

Are these based on IP version or configuration of IP?

I intentionally made it RFC so that all aspects are reviewed as this driver didn't
had an existing binding. I will send out next version with below comment
addressed. Thanks!

RFC means you develop something which is not ready, not sure how to do
it, you send an initial idea. Sending a regular bindings as RFC, without
explaining what you expect, is a bit confusing.
