[PATCH V4 0/5] ARM: exynos: Add l2 retention mode cpuidle state

[amit kachhap]

Hi Mr kim,

All the comments have been addressed for the Exynos cpu idle patchset.
The updated patchset was posted about one month back and there have
been no further comments on the patchset since then.

As this patchset seems to be stable now, do you think these these
patches can merged in this 3.3 merge window? Kindly let me know your
opinion.

Thanks,
Amit Daniel
