This doesn't work. You just allowed any other property to be allowed for 
all these devices. If you need something shared, you have to create a 
common base schema that's referenced by other schemas. Minimally, those

$ref: /to/base/schema.yaml
unevaluatedProperties: false
properties:
  compatible:
    ...
