This patchset is a proposition to improve a bit the code. The changes are code cleanup and does not change the behavior of the driver itself.

Thanks. Will have a look at your series.

Cool, thanks.

A couple a things call my intention. Why the cpuidle device is set for cpu0 only

Because the mainline code CPUIDLE is supported along with CPUhotplug. This is going to change though with Couple CPUIDLE and corresponding OMAP updates.

Ok, thanks for the information. I will look deeper. What happens to cpu1 when it is online and has nothing to do ?

and why the WFI is not used ?

I didn't get this question. Do you mean the generic WFI?

yes.

Quoted 2 lines

If yes, then, it's mainly because OMAP need additional custom barriers.

Ah, ok. I am not sure if it is possible but that may be cool if we can call cpu_do_idle instead with additional barrier.
