dt-bindings: nds32 CPU Bindings

* Andestech Processor Binding

This binding specifies what properties must be available in the device tree

representation of a Andestech Processor Core, which is the root node in the

tree.

Required properties:

	- compatible:

		Usage: required

		Value type: <string>

		Definition: Should be "andestech,<core_name>", "andestech,nds32v3" as fallback.

		Must contain "andestech,nds32v3" as the most generic value, in addition to

		one of the following identifiers for a particular CPU core:

		"andestech,n13"

		"andestech,n15"

		"andestech,d15"

		"andestech,n10"

		"andestech,d10"

	- device_type

		Usage: required

		Value type: <string>

		Definition: must be "cpu"

	- reg: Contains CPU index.

	- clock-frequency: Contains the clock frequency for CPU, in Hz.

* Examples

/ {

	cpus {

		cpu@0 {

			device_type = "cpu";

			compatible = "andestech,n13", "andestech,nds32v3";

			reg = <0x0>;

			clock-frequency = <60000000>

		};

	};
