| 5 | The Energy Aware Scheduler (EAS) used to rely on Energy Models |
| 6 | (EMs) statically defined in the Device Tree. More recent |
| 7 | versions of EAS now rely on the EM framework to get the power |
| 8 | costs of CPUs. |
| 9 | |
| 10 | This driver reads old-style static EMs in DT and feeds them in |
| 11 | the EM framework, hence enabling to use EAS on platforms with |
| 12 | old DT files. Since EAS now uses only the active costs of CPUs, |
| 13 | the cluster-related costs and idle-costs of the old EM are |
| 14 | ignored. |

| 16 | If in doubt, say N. |
