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@ff706000 { compatible = "altr,socfpga-fpga-mgr"; reg = <0xFF706000 0x1000 0xFFB90000 0x1000>; interrupts = <0 175 4>; };
