    +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>;
    + };
    + };
