Merge branch 'samsung/devel-2' into late/soc
Browse files Browse the repository at this point in the history 
From Kukjin Kim <kgene.kim@samsung.com>:

The updating cpufreq for 1.7GHz of exynos5250 has been included in samsung
tree because Rafael thought it was more related in samsung platform and
I agreed.  And others are adding G2D clock for exynos4x12 Socs.

* samsung/devel-2:
  ARM: S3C64XX: Add header file protection macros in pm-core.h
  [CPUFREQ] EXYNOS5250: Add support max 1.7GHz for EXYNOS5250
  ARM: EXYNOS: Add G2D related clock entries for SMDK4X12
  ARM: EXYNOS: Move G2D clock entries to clock-exynos4210.c file

Originally from
git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung.git next/devel-samsung-2
but rebased to split out the defconfig changes.
