Merge tag 'boards' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull arm-soc board specific updates from Arnd Bergmann: "These changes are all for individual board files. In the long run, those files will largely go away, and the amount of changes appears to be continuously decreasing, which is a good sign. This time around, changes are focused on tegra, omap and samsung." Fix conflicts in arch/arm/mach-{omap2/common-board-devices.c,tegra/Makefile.boot} as per the 'for-linus' branch. * tag 'boards' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (39 commits) ARM: EXYNOS: Add leds status1 and status2 on Origen board ARM: S3C64XX: Mark most Cragganmore initdata devinitdata ARM: EXYNOS: Add missing .reserve field to SMDKC210 ARM: EXYNOS: Add DRM device to SMDK4X12 board ARM: S3C64XX: Clean up after SPI driver platform data updates ARM: SAMSUNG: no need to set the value for clk_xusbxti when it is 24Mhz ARM: EXYNOS: Add framebuffer support for SMDK4X12 ARM: EXYNOS: Add HSOTG support to SMDK4X12 ARM: S5PV210: Add audio platform device in Goni board ARM: S5PV210: Add audio platform device in Aquila board ARM: EXYNOS: Add audio platform device in SMDKV310 board ARM: S3C64XX: Don't specify an irq_base for WM1192-EV1 board ARM: OMAP3: Fix omap3evm randconfig error introduced by VBUS support ARM: OMAP: board-omap4panda: MUX configuration for sys_nirq2 ARM: OMAP: board-4430sdp: MUX configuration for sys_nirq2 ARM: OMAP3530evm: set pendown_state and debounce time for ads7846 ARM: omap3evm: enable VBUS switch for EHCI tranceiver ARM: OMAP3EVM: Adding USB internal LDOs board file ARM: OMAP3EVM: Add NAND flash definition ARM: OMAP3: cm-t35: add tvp5150 decoder support ...
