Hi Krzysztof,

Thanks for the comment.

But I have several items for this vendor property in the binding
example.
Can I remove maxItems? Change the mediatek,gce-client-reg as [1].

[1]
  mediatek,gce-client-reg:
    $ref: /schemas/types.yaml#/definitions/phandle-array
    description: The register of display function block to be set by
gce.
      There are 4 arguments in this property, gce node, subsys id,
offset and
      register size. The subsys id is defined in the gce header of each
chips
      include/dt-bindings/gce/<chip>-gce.h, mapping to the register of
display
      function block.

Regards,
Nancy
