Merge tag 'soc-3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC specific changes from Arnd Bergmann: "Lots of changes specific to one of the SoC families. Some that stick out are: - mach-qcom gains new features, most importantly SMP support for the newer chips (Stephen Boyd, Rohit Vaswani) - mvebu gains support for three new SoCs: Armada 375, 380 and 385 (Thomas Petazzoni and Free-electrons team) - SMP support for Rockchips (Heiko Stübner) - Lots of i.MX changes (Shawn Guo) - Added support for BCM5301x SoC (Hauke Mehrtens) - Multiplatform support for Marvell Kirkwood and Dove (Andrew Lunn and Sebastian Hesselbarth doing the final part of a long journey) - Unify davinci platforms and remove obsolete ones (Sekhar Nori, Arnd Bergmann)" * tag 'soc-3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (126 commits) ARM: sunxi: Select HAVE_ARM_ARCH_TIMER ARM: cache-tauros2: remove ARMv6 code ARM: mvebu: don't select CONFIG_NEON ARM: davinci: fix DT booting with default defconfig ARM: configs: bcm_defconfig: enable bcm590xx regulator support ARM: davinci: remove tnetv107x support MAINTAINERS: Update ARM STi maintainers ARM: restrict BCM_KONA_UART to ARCH_BCM_MOBILE ARM: bcm21664: Add board support. ARM: sunxi: Add the new watchog compatibles to the reboot code ARM: enable ARM_HAS_SG_CHAIN for multiplatform ARM: davinci: remove da8xx_omapl_defconfig ARM: davinci: da8xx: fix multiple watchdog device registration ARM: davinci: add da8xx specific configs to davinci_all_defconfig ARM: davinci: enable da8xx build concurrently with older devices ARM: BCM5301X: workaround suppress fault ARM: BCM5301X: add early debugging support ARM: BCM5301X: initial support for the BCM5301X/BCM470X SoCs with ARM CPU ARM: mach-bcm: Remove GENERIC_TIME ARM: shmobile: APMU: Fix warnings due to improper printk formats ...
