[PATCH RFC v2 0/7] Devfreq support for Exynos5250/5420

This patchset adds devfreq support on Exynos5250 and Exynos5420.
The patches add the missing INT clock support for exynos5250 and
also add a new 5420 driver. We also have patches which add the
PPMU node and fix a typo in the exynos5250 driver.

Changes since RFC v1:
	- Exynos5420 support has been added to the existent Exynos5250
	  driver itself.
	- Rebased on Chanwoo Choi's devfreq consolidation patchset.
	- Removed unused clocks from the clock list
	- Used the PPMU nodes with different compatible strings to
	  differentiate between exynos5250 and exynos5420.

The patches have been tested on Exynos5250 based Snow board and Exynos5420
based Peach-Pit boards. They have been prepared on linux-next(20140521) with
the devfreq for-next branch merged. Also applied is the "devfreq resource
management" series from Chanwoo Choi[1].
