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 keeps the current behavior as introduced by Deepthi without
breaking the drivers and add the possibility to specify a per cpu states.
* Tested on intel core 2 duo T9500
* Tested on vexpress by Lorenzo Pieralsi
* Tested on tegra3 by Peter De Schrijver
Daniel Lezcano (6):
acpi : move the acpi_idle_driver variable declaration
acpi : move cpuidle_device field out of the acpi_processor_power
structure
acpi : remove pointless cpuidle device state_count init
cpuidle : add a pointer for cpuidle_state in the cpuidle_device
cpuidle : use per cpuidle device cpu states
cpuidle : add cpuidle_register_states function
