It's somewhat documented with
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/devicetree/bindings/example-schema.yaml#n80
and
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/devicetree/bindings/example-schema.yaml#n102
But I guess it wasn't clear enough? Feel free to update it to
something that would be better
