No, not needed, just inspired from:
 /bindings/clock/samsung,exynos7-clock.yaml

Specifically, the top constraints:
  clocks:

    minItems: 1

    maxItems: 13

One of the conditional constraints:
  clocks:

    minItems: 13

    maxItems: 13


I would only have two arguments for this staying here:
 - It stays consistent with other cases
 - In the case a new device with more than 6 GPIOs is added, this would
need to be put back in
