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.
