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>;
|
|
};
