This patchset adds the generic cpu power control functions for
exynos based SoCs to power up/down and to know the status of the cpu.
Note: This series has been rebased on 3.15-rc1 and tested on
Exynos based Origen(Cortex-A9) and Arndale-octa(Cortex A7,A15) boards.

ARM: EXYNOS: Add generic cpu power control functions for all exynos
based SoCs

Hi Abhilash,
If you are okay with this patchset you can rebase/merge it with your
mcpm patches.
