     1 * Andestech Processor Binding
    2 
    3 This binding specifies what properties must be available in the device tree
    4 representation of a Andestech Processor Core, which is the root node in the
    5 tree.
    6 
    7 Required 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.
