Subject: [PATCH v5 6/6] dt-bindings: fpga: Add bindings for ZynqMP fpga driver

Add documentation to describe Xilinx ZynqMP fpga driver
bindings.

Changes for v5:
		-Moved pcap node as a child to firwmare
		 node as suggested by Rob.
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 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";
+			};
+		};
+	};
