A blank line after each property schema is preferred.

Did you run 'make dt_binding_check' and is dt-schema up to date? This 
isn't valid json-schema which is case sensitive.

Also not valid as allOf is a list.

As is 'enum'...

While you should have this reference, it is at the wrong level. The node 
needs to reference this schema, not the properties.
