It must be pasted from somewhere accidentally, sorry.

Sorry for misunderstanding from original example. I rechecked the example and made a modification as below, before sending out new patch, would you mind help me review it and let me know if anything improper? Thank you.


dependencies:
  adi,enable-power-sample-average: [ 'adi,power-sample-average' ]
  adi,power-sample-average: [ 'adi,enable-power-sample-average' ]

allOf:
  - if:
      properties:
        compatible:
          contains:
            enum:
              - adi,adm1272
              - adi,adm1278
              - adi,adm1293
              - adi,adm1294
    then:
      required:
        - adi,enable-power-sample-average
    else:
      properties:
        adi,enable-power-sample-average: false
