+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";
+ };
+ };
+ };
