Merge branch 'next/dt-samsung-2' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung into next/dt
From Kukjin Kim: Here is second Samsung DT stuff for v3.8. This is including power domain DT support for exynos and Google ARM Chromebook, Snow board and exynos4210-origen updates. * 'next/dt-samsung-2' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung: ARM: dts: Use drive strength 3 for SD pins for exynos4 ARM: dts: Set up power domains for exynos4 ARM: EXYNOS: Bind devices to power domains using DT ARM: EXYNOS: Fix power domain name initialization ARM: EXYNOS: Detect power domain state on registration from DT ARM: dts: Add vmmc fixed voltage regulator for exynos4210-origen ARM: dts: Update sdhci nodes for current bindings for exynos4210-origen ARM: dts: Update for pinctrl-samsung driver for exynos4210-origen ARM: dts: Split memory sections for exynos4210-origen ARM: EXYNOS: add all i2c busses to auxdata for DT ARM: dts: Add aliases for i2c controller for exynos4 ARM: dts: Add board dts file for Snow board (ARM Chromebook) ARM: dts: Move the dwmmc aliases from smdk5250 dts to exynos Add/add conflicts resolved in arch/arm/boot/dts/exynos5250-smdk5250.dts and arch/arm/mach-exynos/mach-exynos5-dt.c.
