+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:
+
+ firmware {
+ zynqmp-firmware {
+ compatible = "xlnx,zynqmp-pm";
+ method = "smc";
+ interrupt-parent = <&gic>;
+ interrupts = <0 35 4>;
+ };
+ };
