Okay. I was under the impression 'clock-frequency' was removed thinking 
it is in the i2c bus schema already. It is, but unfortunately you need 
it here too if used because all properties for a node have to be listed 
in the schema for the node. 'unevaluatedProperties' can't evaluate 
properties in the child nodes of the parent schema with the properties 
of the child schema.
