Cover letter [PATCH 0/8] ARM: move cpuidle drivers to drivers/cpuidle/

Hi,
This patchset moves ARM cpuidle drivers to
drivers/cpuidle/to make code match new driver placement rules (per commit a8e39c3 "cpuidle: add maintainer entry").
Quoted 5 lines
I second this initiative but as stated in a previous email, a bit of code cleanup, consolidation and encapsulation should be done before.
Again, from my POV, it is worth to do that but we have to split the pm code from the driver.
OK, I'll look into separating the pm code from the drivers. However it seems that patch #2 (for davinci) can be applied as it is.

Please review some patches I sent recently to split this code and comment them. Otherwise, we will collide on this work.
All the patches sent [1] was to unify the code to make the drivers as unified as possible to converge to the same code pattern and to facilitate the factoring out.
I've looked at the patches ([1] and at91 ones) and they look fine to me.
I don't think that there is currently a risk of colliding on this work (except at91 case) as your patches (except at91 ones) are already merged in upstream or linux-next branch of linux-pm tree (which is included in linux-next tree which I based my patches on). I'm subscribed to linux-pm mailing list now but please cc: me on your future ARM cpuidle changes (thanks!).
Best regards,

[ Please note that movement of Samsung EXYNOS cpuidle driver is handled
in separate patchset since it needs some other changes applied first. ]Patches are based on linux-next (next-20130624) and are compile tested only. If agreed they all should probably go together through one tree (linux-pm or arm-soc) since they all modify
drivers/cpuidle/Makefile.PS It seems that majority of cpuidle drivers is not used by default (
CONFIG_CPU_IDLEis not turned on in corresponding defconfigs). The only exceptions are shmobile (kota2_defconfig) and tegra (tegra_defconfig). This is probably also something that needs updating.Best regards,
