Merge branch 'next/soc-exynos5250-gpio' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung into next/drivers

* 'next/soc-exynos5250-gpio' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung: (201 commits)
  gpio/samsung: use ioremap() for EXYNOS4 GPIOlib
  gpio/samsung: add support GPIOlib for EXYNOS5250
  ARM: EXYNOS: add support GPIO for EXYNOS5250
(update to v3.3-rc7)

Conflicts:
	arch/arm/mach-pxa/pxa25x.c
	arch/arm/mach-pxa/pxa27x.c

The dummy clock for the pxa rtc in those files keeps getting added and
removed in various trees. Apparently removing is the correct solution.
