Secondary CPU enable-method "al,alpine-smp" binding
|
||
|
|
========================================================
|
||
|
|
|
||
|
|
This document describes the "al,alpine-smp" method for
|
||
|
|
enabling secondary CPUs. To apply to all CPUs, a single
|
||
|
|
"al,alpine-smp" enable method should be defined in the
|
||
|
|
"cpus" node.
|
||
|
|
|
||
|
|
Enable method name: "al,alpine-smp"
|
||
|
|
Compatible machines: "al,alpine"
|
||
|
|
Compatible CPUs: "arm,cortex-a15"
|
||
|
|
Related properties: (none)
|
||
|
|
|
||
|
|
Note:
|
||
|
|
This enable method requires valid nodes compatible with
|
||
|
|
"al,alpine-cpu-resume" and "al,alpine-nb-service"[1].
|
||
|
|
|
||
|
|
Example:
|
||
|
|
|
||
|
|
cpus {
|
||
|
|
#address-cells = <1>;
|
||
|
|
#size-cells = <0>;
|
||
|
|
enable-method = "al,alpine-smp";
|
||
|
|
|
||
|
|
cpu@0 {
|
||
|
|
compatible = "arm,cortex-a15";
|
||
|
|
device_type = "cpu";
|
||
|
|
reg = <0>;
|
||
|
|
};
|
||
|
|
|
||
|
|
cpu@1 {
|
||
|
|
compatible = "arm,cortex-a15";
|
||
|
|
device_type = "cpu";
|
||
|
|
reg = <1>;
|
||
|
|
};
|
||
|
|
|
||
|
|
cpu@2 {
|
||
|
|
compatible = "arm,cortex-a15";
|
||
|
|
device_type = "cpu";
|
||
|
|
reg = <2>;
|
||
|
|
};
|
||
|
|
|
||
|
|
cpu@3 {
|
||
|
|
compatible = "arm,cortex-a15";
|
||
|
|
device_type = "cpu";
|
||
|
|
reg = <3>;
|
||
|
|
};
|
||
|
|
};
