The clkoutN names of clocks must be unique because they represent
unique inputs of clock multiplexer.

You shouldn't need the 'allOf', just add uniqueItems at the same level as items.

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
