+Altera SOCFPGA FPGA Manager
+
+Required properties:
+- compatible : should contain "altr,socfpga-fpga-mgr"
+- reg : base address and size for memory mapped io.
+ - The first index is for FPGA manager register access.
+ - The second index is for writing FPGA configuration data.
+- interrupts : interrupt for the FPGA Manager device.
+
+Example:
+
+ hps_0_fpgamgr: fpgamgr@0xff706000 {
+ compatible = "altr,socfpga-fpga-mgr";
+ reg = <0xFF706000 0x1000
+ 0xFFB90000 0x1000>;
+ interrupts = <0 175 4>;
+ };
