-Devicetree bindings for Zynq Ultrascale MPSoC FPGA Manager.
-The ZynqMP SoC uses the PCAP (Processor configuration Port) to configure the
-Programmable Logic (PL). The configuration uses  the firmware interface.
-
-Required properties:
-- compatible: should contain "xlnx,zynqmp-pcap-fpga"
-
-Example for full FPGA configuration:
-
-	fpga-region0 {
-		compatible = "fpga-region";
-		fpga-mgr = <&zynqmp_pcap>;
-		#address-cells = <0x1>;
-		#size-cells = <0x1>;
-	};
-
-	firmware {
-		zynqmp_firmware: zynqmp-firmware {
-			compatible = "xlnx,zynqmp-firmware";
-			method = "smc";
-			zynqmp_pcap: pcap {
-				compatible = "xlnx,zynqmp-pcap-fpga";
-			};
-		};
-	};
