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
Pulled, thanks!
I'd appreciate earlier pull requests in the future, though.
Rafael
