Changes for v4:
		-Modified binding description as suggested by Moritz Fischer.
Changes for v3:
                -Removed PCAP as a child node to the FW and Created
		 an independent node since PCAP driver is a consumer
		 not a provider.

+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:
+	zynqmp_pcap: pcap {
+		compatible = "xlnx,zynqmp-pcap-fpga";
+	};
