Since commit 46bcfad7a819bd17ac4e831b04405152d59784ab, cpuidle: Single/Global registration of idle states
we have a single registration for the cpuidle states which makes sense. But now two new architectures are coming: tegra3 and big.LITTLE.
These architectures have different cpus with different caracteristics for power saving. High load => powerfull processors, idle => small processors.
That implies different cpu latencies.
This patchset present a simple way to keep the current behavior as introduced by Deepthi without breaking the drivers and add the possibility to specify a per cpu states.
Daniel Lezcano (5): acpi : move the acpi_idle_driver variable declaration acpi : move cpuidle_device field out of the acpi_processor_power structure cpuidle : add a pointer for cpuidle_state in the cpuidle_device cpuidle : use per cpuidle device cpu states cpuidle : add cpuidle_register_states function
