Hi Krzysztof,

Sorry to bug you again about this property, could it be changed to
following form.

    mediatek,gce-client-reg:
      $ref: /schemas/types.yaml#/definitions/phandle-array
      items:
        items:
          - description: phandle of GCE
          - description: GCE subsys id
          - description: register offset
          - description: register size
      description:
        ... defined in <include/dt-bindings/gce/mt8195-gce.h>.
     maxItems: 1 
  
Also, is the include header path still necessary in this form?

Sincerely,
Moudy
