+Xilinx Zynq MPSoC Power Management Device Tree Bindings
+
+The zynqmp-power node describes the power management configurations.
+
+Required properties:
+ - compatible : Must contain: "xlnx,zynqmp-power"
+ - mbox-names : Name given to channels seen in the 'mboxes' property.
+ "rx" - Mailbox corresponding to receive path
+ "tx" - Mailbox corresponding to transmit 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.
+
+Examples:
+ zynqmp_power: zynqmp-power {
+ compatible = "xlnx,zynqmp-power";
+ mboxes = <&ipi_mailbox_pmu0 0>,
+ <&ipi_mailbox_pmu0 1>;
+ mbox-names = "tx", "rx";
+ };
