  The zynqmp-power node describes the power management configurations.
  It will control remote suspend/shutdown interfaces.

  mboxes:
    description: |
      Standard property to specify a Mailbox. Each value of
      the mboxes property should contain a phandle to the
      mailbox controller device node and an args specifier
      that will be the phandle to the intended sub-mailbox
      child node to be used for communication. See
      Documentation/devicetree/bindings/mailbox/mailbox.txt
      for more details about the generic mailbox controller
      and client driver bindings. Also see
      Documentation/devicetree/bindings/mailbox/ \
      xlnx,zynqmp-ipi-mailbox.txt for typical controller that
      is used to communicate with this System controllers.
