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.
