+Binding for Synopsys IntelliDDR Multi Protocol Memory Controller
+
+This controller has an optional ECC support in half-bus width (16-bit)
+configuration. The ECC controller corrects one bit error and detects
+two bit errors.
+
+Required properties:
+ - compatible: Should be 'xlnx,zynq-ddrc-a05'
+ - reg: Base address and size of the controllers memory area
+
+Example:
+	memory-controller@f8006000 {
+		compatible = "xlnx,zynq-ddrc-a05";
+		reg = <0xf8006000 0x1000>;
+	};
