This is not a driver.

oneOf is not necessary as there is only one of.

Please run 'make dt_binding_check'. You'll find this is not valid json-schema.

Examples are built now and this will have an error. The default
address and size cells are 1 for examples, so you either have to
override them or adjust this.

Don't show status in examples.
