Every time I change I definitely do dtbs_check test.
But There is no error reported by dtbs_check.

But finally I understand that
anyOf:
  - required:
      - spdif-in
  - required:
      - spdif-out
  - required:
      - spdif-out
      - spdif-in

is equal to:
anyOf:
  - required:
      - spdif-in
  - required:
      - spdif-out
