Merge tag 'soc-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC platform changes from Olof Johansson: "New core SoC-specific changes. New platforms: * Introduction of a vendor, Hisilicon, and one of their SoCs with some random numerical product name. * Introduction of EFM32, embedded platform from Silicon Labs (ARMv7m, i.e. !MMU). * Marvell Berlin series of SoCs, which include the one in Chromecast. * MOXA platform support, ARM9-based platform used mostly in industrial products * Support for Freescale's i.MX50 SoC. Other work: * Renesas work for new platforms and drivers, and conversion over to more multiplatform-friendly device registration schemes. * SMP support for Allwinner sunxi platforms. * ... plus a bunch of other stuff across various platforms" * tag 'soc-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (201 commits) ARM: tegra: fix tegra_powergate_sequence_power_up() inline ARM: msm_defconfig: Update for multi-platform ARM: msm: Move MSM's DT based hardware to multi-platform support ARM: msm: Only build timer.c if required ARM: msm: Only build clock.c on proc_comm based platforms ARM: ux500: Enable system suspend with WFI support ARM: ux500: turn on PRINTK_TIME in u8500_defconfig ARM: shmobile: r8a7790: Fix I2C controller names ARM: msm: Simplify ARCH_MSM_DT config ARM: msm: Add support for MSM8974 SoC ARM: sunxi: select ARM_PSCI MAINTAINERS: Update Allwinner sunXi maintainer files ARM: sunxi: Select RESET_CONTROLLER ARM: imx: improve the comment of CCM lpm SW workaround ARM: imx: improve status check of clock gate ARM: imx: add necessary interface for pfd ARM: imx_v6_v7_defconfig: Select CONFIG_REGULATOR_PFUZE100 ARM: imx_v6_v7_defconfig: Select MX35 and MX50 device tree support ARM: imx: Add cpu frequency scaling support ARM i.MX35: Add devicetree support. ...
