Binding for Synopsys IntelliDDR Multi Protocol Memory Controller

+Synopsys EDAC driver, it does reports the DDR ECC single bit errors
+that are corrected and double bit ecc errors that are detected by the DDR
+ECC controller.
+
+The Zynq DDR ECC 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
+ - 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":
+ - interrupt-parent: Should be core interrupt controller.
+ - 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>;
+ };
