Merge tag 'soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC-specific updates from Arnd Bergmann: "This is a larger set of new functionality for the existing SoC families, including: - vt8500 gains support for new CPU cores, notably the Cortex-A9 based wm8850 - prima2 gains support for the "marco" SoC family, its SMP based cousin - tegra gains support for the new Tegra4 (Tegra114) family - socfpga now supports a newer version of the hardware including SMP - i.mx31 and bcm2835 are now using DT probing for their clocks - lots of updates for sh-mobile - OMAP updates for clocks, power management and USB - i.mx6q and tegra now support cpuidle - kirkwood now supports PCIe hot plugging - tegra clock support is updated - tegra USB PHY probing gets implemented diffently" * tag 'soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (148 commits) ARM: prima2: remove duplicate v7_invalidate_l1 ARM: shmobile: r8a7779: Correct TMU clock support again ARM: prima2: fix __init section for cpu hotplug ARM: OMAP: Consolidate OMAP USB-HS platform data (part 3/3) ARM: OMAP: Consolidate OMAP USB-HS platform data (part 1/3) arm: socfpga: Add SMP support for actual socfpga harware arm: Add v7_invalidate_l1 to cache-v7.S arm: socfpga: Add entries to enable make dtbs socfpga arm: socfpga: Add new device tree source for actual socfpga HW ARM: tegra: sort Kconfig selects for Tegra114 ARM: tegra: enable ARCH_REQUIRE_GPIOLIB for Tegra114 ARM: tegra: Fix build error w/ ARCH_TEGRA_114_SOC w/o ARCH_TEGRA_3x_SOC ARM: tegra: Fix build error for gic update ARM: tegra: remove empty tegra_smp_init_cpus() ARM: shmobile: Register ARM architected timer ARM: MARCO: fix the build issue due to gic-vic-to-irqchip move ARM: shmobile: r8a7779: Correct TMU clock support ARM: mxs_defconfig: Select CONFIG_DEVTMPFS_MOUNT ARM: mxs: decrease mxs_clockevent_device.min_delta_ns to 2 clock cycles ARM: mxs: use apbx bus clock to drive the timers on timrotv2 ...
