- ========================================================
- 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>;
- };
- };
