3This binding specifies what properties must be available in the device tree
4representation of a Andestech Processor Core, which is the root node in the
5tree.

7Required properties:
8
9 - compatible:
10 Usage: required
11 Value type: <string>
12 Definition: Should be "andestech,<core_name>", "andestech,nds32v3" as fallback.
13 Must contain "andestech,nds32v3" as the most generic value, in addition to
14 one of the following identifiers for a particular CPU core:
15 "andestech,n13"
16 "andestech,n15"
17 "andestech,d15"
18 "andestech,n10"
19 "andestech,d10"
20 - device_type
21 Usage: required
22 Value type: <string>
23 Definition: must be "cpu"
24 - reg: Contains CPU index.
25 - clock-frequency: Contains the clock frequency for CPU, in Hz.
