If you mean something like: 56 uniqueItems: true 57 items: 58 pattern: '^clkout([0-9]|[12][0-9]|3[0-1])$' Then the dt_binding_check fails: dev/linux/Documentation/devicetree/bindings/arm/samsung/pmu.yaml: properties:clock-names: 'uniqueItems' is not one of ['$ref', 'additionalItems', 'additionalProperties', 'allOf', 'anyOf', 'const', 'contains', 'default', 'dependencies', 'deprecated', 'description', 'else', 'enum', 'items', 'if', 'minItems', 'minimum', 'maxItems', 'maximum', 'not', 'oneOf', 'pattern', 'patternProperties', 'properties', 'required', 'then', 'type', 'typeSize', 'unevaluatedProperties'] Best regards, Krzysztof
