From Kukjin Kim <kgene.kim@samsung.com>:

including various development for samsung for v3.10

* tag 'devel-samsung-for-v3.10' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung:
  ARM: EXYNOS: replace cpumask by the corresponding macro
  ARM: EXYNOS: handle properly the return values
  ARM: EXYNOS: factor out the idle states
  ARM: SAMSUNG: check processor type before cache restoration in resume
  ARM: S3C64XX: Slow down mic detection rate for wm5102
  ARM: S3C64XX: Clear DMA flags on channel request
  ARM: EXYNOS: Clear ENABLE_WAKEUP_SW bit when entering suspend
  ARM: EXYNOS: Remove hardcode wakeup unmask for EINT_0
  ARM: EXYNOS: Add support for rtc wakeup
  ARM: SAMSUNG: Export MIPI CSIS/DSIM PHY control functions
