The property is an enum Why this maxItems value ?
Hm, it's an array, but you are right that enum forces dtschema to interpret it as scalar value, so your code is correct.
If I add the maxItems value, I've got some dt_binding_check errors: /xxxx/bindings/soc/fsl/cpm_qe/fsl,cpm1-tsa.yaml: patternProperties:^tdm@[0-1]$:properties:fsl,rx-frame-sync-delay-bits: 'enum' should not be valid under {'enum': ['const', 'enum', 'exclusiveMaximum', 'exclusiveMinimum', 'minimum', 'maximum', 'multipleOf', 'pattern']} hint: Scalar and array keywords cannot be mixed from schema $id: http://devicetree.org/meta-schemas/keywords.yaml#
