+Required properties:
+- compatible : "altr,sdr-ctl", "syscon";
+ Note that syscon is invoked for this device to support the FPGA
+ bridge driver, EDAC driver and other devices that share the
+ registers.
+- reg : Should contain 1 register ranges(address and length)

+Example:
+ sdrctl@ffc25000 {
+ compatible = "altr,sdr-ctl", "syscon";
+ reg = <0xffc25000 0x1000>;
