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>;
	};
