Drop. Don't need generic descriptions of common properties.

This needs to define exact sizes.

items:
  - items:
      - description: phandle to GCE
      - description: subsy id
      - description: register offset
      - description: register size

  Each mmsys belongs to a power-domains, so we can add the power-
  domains property to make it clearer, and also bind to the power
  controller.

  If using mailbox to communicate with GCE, it should have this
  property. GCE will help configure the hardware settings for the

OK, I'll fix it like this:

mediatek,gce-client-reg:
  minItems: 1
  items:
    - items:
        - description: phandle to GCE
        - description: subsys id
