Merge tag 'soc-for-3.16' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc into next
Pull part one of ARM SoC updates from Olof Johansson: "A quite large set of SoC updates this cycle. In no particular order: - Multi-cluster power management for Samsung Exynos, adding support for big.LITTLE CPU switching on EXYNOS5 - SMP support for Marvell Armada 375 and 38x - SMP rework on Allwinner A31 - Xilinx Zynq support for SOC_BUS, big endian - Marvell orion5x platform cleanup, modernizing the implementation and moving to DT. - _Finally_ moving Samsung Exynos over to support MULTIPLATFORM, so that their platform can be enabled in the same kernel binary as most of the other v7 platforms in the tree. \o/ The work isn't quite complete, there's some driver fixes still needed, but the basics now work. New SoC support added: - Freescale i.MX6SX - LSI Axxia AXM55xx SoCs - Samsung EXYNOS 3250, 5260, 5410, 5420 and 5800 - STi STIH407 plus a large set of various smaller updates for different platforms. I'm probably missing some important one here" * tag 'soc-for-3.16' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (281 commits) ARM: exynos: don't run exynos4 l2x0 setup on other platforms ARM: exynos: Fix "allmodconfig" build errors in mcpm and hotplug ARM: EXYNOS: mcpm rename the power_down_finish ARM: EXYNOS: Enable mcpm for dual-cluster exynos5800 SoC ARM: EXYNOS: Enable multi-platform build support ARM: EXYNOS: Consolidate Kconfig entries ARM: EXYNOS: Add support for EXYNOS5410 SoC ARM: EXYNOS: Support secondary CPU boot of Exynos3250 ARM: EXYNOS: Add Exynos3250 SoC ID ARM: EXYNOS: Add 5800 SoC support ARM: EXYNOS: initial board support for exynos5260 SoC clk: exynos5410: register clocks using common clock framework ARM: debug: qcom: add UART addresses to Kconfig help for APQ8084 ARM: sunxi: allow building without reset controller Documentation: devicetree: arm: sort enable-method entries ARM: rockchip: convert smp bringup to CPU_METHOD_OF_DECLARE clk: exynos5250: Add missing sysmmu clocks for DISP and ISP blocks ARM: dts: axxia: Add reset controller power: reset: Add Axxia system reset driver ARM: axxia: Adding defconfig for AXM55xx ...
