+Binding for Synopsys IntelliDDR Multi Protocol Memory Controller
+
+The ZynqMP DDR ECC controller has an optional ECC support in 64-bit and 32-bit
+bus width configurations.
+
+The Zynq DDR ECC controller has an optional ECC support in half-bus width
+(16-bit) configuration.
+
+These both ECC controllers correct single bit ECC errors and detect double bit
+ECC errors.
+
+Required properties:
+ - compatible: One of:
+	- 'xlnx,zynq-ddrc-a05' : Zynq DDR ECC controller
+	- 'xlnx,zynqmp-ddrc-2.40a' : ZynqMP DDR ECC controller
+ - reg: Should contain DDR controller registers location and length.
+
+Required properties for "xlnx,zynqmp-ddrc-2.40a":
+ - interrupts: Property with a value describing the interrupt number.
+
+Example:
+	memory-controller@f8006000 {
+		compatible = "xlnx,zynq-ddrc-a05";
+		reg = <0xf8006000 0x1000>;
+	};
+
+	mc: memory-controller@fd070000 {
+		compatible = "xlnx,zynqmp-ddrc-2.40a";
+		reg = <0x0 0xfd070000 0x0 0x30000>;
+		interrupt-parent = <&gic>;
+		interrupts = <0 112 4>;
+	};
