Secondary CPU enable-method "marvell,berlin-smp" binding
|
|
========================================================
|
|
|
|
This document describes the "marvell,berlin-smp" method for enabling secondary
|
|
CPUs. To apply to all CPUs, a single "marvell,berlin-smp" enable method should
|
|
be defined in the "cpus" node.
|
|
|
|
Enable method name: "marvell,berlin-smp"
|
|
Compatible machines: "marvell,berlin2" and "marvell,berlin2q"
|
|
Compatible CPUs: "marvell,pj4b" and "arm,cortex-a9"
|
|
Related properties: (none)
|
|
|
|
Note:
|
|
This enable method needs valid nodes compatible with "arm,cortex-a9-scu" and
|
|
"marvell,berlin-cpu-ctrl"[1].
|
|
|
|
Example:
|
|
|
|
cpus {
|
|
#address-cells = <1>;
|
|
#size-cells = <0>;
|
|
enable-method = "marvell,berlin-smp";
|
|
|
|
cpu@0 {
|
|
compatible = "marvell,pj4b";
|
|
device_type = "cpu";
|
|
next-level-cache = <&l2>;
|
|
reg = <0>;
|
|
};
|
|
|
|
cpu@1 {
|
|
compatible = "marvell,pj4b";
|
|
device_type = "cpu";
|
|
next-level-cache = <&l2>;
|
|
reg = <1>;
|
|
};
|
|
};
