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

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