Only SMP system need to care about the cpus node and single processor needn't define cpus node at all. ===================================== cpus and cpu node bindings definition ===================================== - cpus node Description: Container of cpu nodes The node name must be "cpus". A cpus node must define the following properties: - #address-cells Usage: required Value type: <u32> Definition: must be set to 1 - #size-cells Usage: required Value type: <u32> Definition: must be set to 0 - cpu node Description: Describes one of SMP cores PROPERTIES - device_type Usage: required Value type: <string> Definition: must be "cpu" - reg Usage: required Value type: <u32> Definition: CPU index - compatible: Usage: required Value type: <string> Definition: must contain "csky", eg: "csky,610" "csky,807" "csky,810" "csky,860" Example: -------- cpus { #address-cells = <1>; #size-cells = <0>; cpu@0 { device_type = "cpu"; reg = <0>; status = "ok"; }; cpu@1 { device_type = "cpu"; reg = <1>; status = "ok"; }; }; |
