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
