[PATCH] dt-bindings: power: Add missing (unevaluated|additional)Properties on child nodes

Rob Herring robh at kernel.org
Tue Aug 23 07:56:46 PDT 2022


In order to ensure only documented properties are present, node schemas
must have unevaluatedProperties or additionalProperties set to false
(typically).
