| 2 | Secondary CPU enable-method "al,alpine-smp" binding |
| 3 | ======================================================== |
| 4 | |
| 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 |
| 8 | "cpus" node. |
| 9 | |
| 10 | Enable method name: "al,alpine-smp" |
| 11 | Compatible machines: "al,alpine" |
| 12 | Compatible CPUs: "arm,cortex-a15" |
| 13 | Related properties: (none) |
| 14 | |
| 15 | Note: |
| 16 | This enable method requires valid nodes compatible with |
| 17 | "al,alpine-cpu-resume" and "al,alpine-nb-service"[1]. |
| 18 | |
| 19 | Example: |
| 20 | |
| 21 | cpus { |
| 22 | #address-cells = <1>; |
| 23 | #size-cells = <0>; |
| 24 | enable-method = "al,alpine-smp"; |
| 25 | |
| 26 | cpu@0 { |
| 27 | compatible = "arm,cortex-a15"; |
| 28 | device_type = "cpu"; |
| 29 | reg = <0>; |
| 30 | }; |
| 31 | |
| 32 | cpu@1 { |
| 33 | compatible = "arm,cortex-a15"; |
| 34 | device_type = "cpu"; |
| 35 | reg = <1>; |
| 36 | }; |
| 37 | |
| 38 | cpu@2 { |
| 39 | compatible = "arm,cortex-a15"; |
| 40 | device_type = "cpu"; |
| 41 | reg = <2>; |
| 42 | }; |
| 43 | |
| 44 | cpu@3 { |
| 45 | compatible = "arm,cortex-a15"; |
| 46 | device_type = "cpu"; |
| 47 | reg = <3>; |
| 48 | }; |
| 49 | }; |
