* 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>
|
|
};
|
|
};
|
