+Xilinx Zynq MPSoC Firmware Device Tree Bindings
+
+The zynqmp-pm node describes the interface to platform firmware.
+
+Required properties:
+ - compatible: Must contain:  "xlnx,zynqmp-pm"
+ - method:     The method of calling the PM-API firmware layer.
+               Permitted values are:
+                - "smc" : To be used in configurations without a hypervisor
+                - "hvc" : To be used when hypervisor is present
+ - interrupts: Interrupt specifier
+
+Examples:
+       zynqmp-firmware {
+               compatible = "xlnx,zynqmp-pm";
+               method = "smc";
+               interrupt-parent = <&gic>;
+               interrupts = <0 35 4>;
+       };
