2 Secondary CPU enable-method "marvell,berlin-smp" binding

5 This document describes the "marvell,berlin-smp" method for enabling secondary
6 CPUs. To apply to all CPUs, a single "marvell,berlin-smp" enable method should
7 be defined in the "cpus" node.
8
9 Enable method name: "marvell,berlin-smp"
10 Compatible machines: "marvell,berlin2" and "marvell,berlin2q"
11 Compatible CPUs: "marvell,pj4b" and "arm,cortex-a9"
12 Related properties: (none)
13
14 Note:
15 This enable method needs valid nodes compatible with "arm,cortex-a9-scu" and
16 "marvell,berlin-cpu-ctrl"[1].
17
18 Example:
19
20 cpus {
21 #address-cells = <1>;
22 #size-cells = <0>;
23 enable-method = "marvell,berlin-smp";
24
25 cpu@0 {
26 compatible = "marvell,pj4b";
27 device_type = "cpu";
28 next-level-cache = <&l2>;
29 reg = <0>;
30 };
31
32 cpu@1 {
33 compatible = "marvell,pj4b";
34 device_type = "cpu";
35 next-level-cache = <&l2>;
36 reg = <1>;
37 };
38 };
