Merge tag 'boards' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull "ARM: board specific updates" from Arnd Bergmann/Olof Johansson: "These changes are all specific to one board only. We're trying to keep the number of board files low, but generally board level updates are ok on platforms that are working on moving towards DT based probing, which will eventually lead to removing them. The board-ams-delta.c board file gets a conflict between the removal of ams_delta_config and the addition of a lot of other data. The Kconfig file has two changes in the same line, and in exynos, the power domain cleanup conflicts with the addition of the image sensor device. Signed-off-by: Arnd Bergmann <arnd@arndb.de> [olof: Amended a fix for a mismerge to board-omap4panda.c] Signed-off-by: Olof Johansson <olof@lixom.net>" Fixed up some fairly trivial conflicts manually. * tag 'boards' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (82 commits) i.MX35-PDK: Add Camera support ARM : mx35: 3ds-board: add framebuffer device pxa/hx4700: Remove pcmcia platform_device structure ARM: pxa/hx4700: Reduce sleep mode battery discharge by 35% ARM: pxa/hx4700: Remove unwanted request for GPIO105 ARM: EXYNOS: support Exynos4210-bus Devfreq driver on Nuri board ARM: EXYNOS: Register JPEG on nuri ARM: EXYNOS: Register JPEG on universal_c210 ARM: S5PV210: Enable JPEG on SMDKV210 ARM: S5PV210: Add JPEG board definition ARM: EXYNOS: Enable JPEG on Origen ARM: EXYNOS: Enable JPEG on SMDKV310 ARM: EXYNOS: Add __init attribute to universal_camera_init() ARM: EXYNOS: Add __init attribute to nuri_camera_init() ARM: S5PV210: Enable FIMC on SMDKC110 ARM: S5PV210: Enable FIMC on SMDKV210 ARM: S5PV210: Enable MFC on SMDKC110 ARM: S5PV210: Enable MFC on SMDKV210 ARM: EXYNOS: Enable G2D on SMDKV310 ARM: tegra: update defconfig ...
