-Device Tree Bindings for the Xilinx Zynq MPSoC Power Management
---------------------------------------------------------------------
-The zynqmp-power node describes the power management configurations.
-It will control remote suspend/shutdown interfaces.
-
-Required properties:
- - compatible:		Must contain:	"xlnx,zynqmp-power"
- - interrupts:		Interrupt specifier
-
-Optional properties:
- - mbox-names	: Name given to channels seen in the 'mboxes' property.
-		  "tx" - Mailbox corresponding to transmit path
-		  "rx" - Mailbox corresponding to receive path
- - mboxes	: 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.
