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. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
