2 Secondary CPU enable-method "al,alpine-smp" binding
3 ========================================================
5 This document describes the "al,alpine-smp" method for
6 enabling secondary CPUs. To apply to all CPUs, a single
7 "al,alpine-smp" enable method should be defined in the
10 Enable method name: "al,alpine-smp"
11 Compatible machines: "al,alpine"
12 Compatible CPUs: "arm,cortex-a15"
13 Related properties: (none)
16 This enable method requires valid nodes compatible with
17 "al,alpine-cpu-resume" and "al,alpine-nb-service".
20 * Alpine CPU resume registers
22 The CPU resume register are used to define required resume address after
26 - compatible : Should contain "al,alpine-cpu-resume".
27 - reg : Offset and length of the register set for the device
30 * Alpine System-Fabric Service Registers
32 The System-Fabric Service Registers allow various operation on CPU and
33 system fabric, like powering CPUs off.
36 - compatible : Should contain "al,alpine-sysfabric-service" and "syscon".
37 - reg : Offset and length of the register set for the device
