I have doubts you actually tested it - there is no type/ref. Also,
your description is a bit different than existing from dtschema. Why?
Aren't these the same things?

Ah, I'll add 
$ref: /schemas/types.yaml#/definitions/flag

I ran dt_binding_check andmake dt_binding_check \    
  DT_SCHEMA_FILES=Documentation/devicetree/bindings/i3c/i3c.yaml

?
