      This node contains a hierarchy of PM domain nodes, which should match the
      Power Area Hierarchy in the Power Domain Specifications section of the
      device's datasheet.

  pd-node:
    type: object
    description:
      PM domain node representing a PM domain.  This node should be named by
      the real power area name, and thus its name should be unique.

    properties:
      reg:
        maxItems: 1
        description:
          If the PM domain is not always-on, this property must contain the
          bit index number for the corresponding power area in the various
          Power Control and Status Registers.
