Subject: [GIT PULL] cpuidle ARM new material for 3.18


[resent because of the missing Cc]

Hi Rafael,

this pull request contains the following changes:

  * Lorenzo Pieralisi implemented a framework to initialize the ARM 
cpuidle drivers with the DT. As an example, it provided a couple of 
drivers using it: arm64 and big little. The former one is a new driver 
while the latter is a change. There was also a patch for Exynos allowing 
to use this framework but as it depends on a change in Samsung's tree, I 
postponed this patch until the change is visible after the merge. The 
set of changes depends on some other changes made in the ARM64 tree, for 
this reason a shared branch is used. This is why there is a merge from 
arm64 in my pull request. I believe we already used this procedure.

  * Kevin Hilman added the compatible string for the exynos 5800 in the DT

Thanks !
