Merge tag 'dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Device tree conversions for samsung and tegra Both platforms had some initial device tree support, but this adds much more to actually make it usable. * tag 'dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (45 commits) ARM: dts: Add intial dts file for EXYNOS4210 SoC, SMDKV310 and ORIGEN ARM: EXYNOS: Add Exynos4 device tree enabled board file rtc: rtc-s3c: Add device tree support input: samsung-keypad: Add device tree support ARM: S5PV210: Modify platform data for pl330 driver ARM: S5PC100: Modify platform data for pl330 driver ARM: S5P64x0: Modify platform data for pl330 driver ARM: EXYNOS: Add a alias for pdma clocks ARM: EXYNOS: Limit usage of pl330 device instance to non-dt build ARM: SAMSUNG: Add device tree support for pl330 dma engine wrappers DMA: PL330: Add device tree support ARM: EXYNOS: Modify platform data for pl330 driver DMA: PL330: Infer transfer direction from transfer request instead of platform data DMA: PL330: move filter function into driver serial: samsung: Fix build for non-Exynos4210 devices serial: samsung: add device tree support serial: samsung: merge probe() function from all SoC specific extensions serial: samsung: merge all SoC specific port reset functions ARM: SAMSUNG: register uart clocks to clock lookup list serial: samsung: remove all uses of get_clksrc and set_clksrc ... Fix up fairly trivial conflicts in arch/arm/mach-s3c2440/clock.c and drivers/tty/serial/Kconfig both due to just adding code close to changes.
