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. Changes since RFC v2: - Re-based on the latest devfreq/samsung clock tree. - Fixed comment from Sergei Shtylyov. The patches have been tested on Exynos5250 based Snow board and Exynos5420 based Peach-Pit boards. They have been prepared on linux-next(20140714) with the samsung clk-next branch merged[1].
