This "compatible" name is a bit too generic. No, I don't know a
better name :-(

What is a label? It should be described here. Also, its encoding
should be described ("a string" I guess).

You show a unit address but have no "reg" value. This is
incorrect.
What would be the parent node of this, btw?
