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 and updated SoC support. Among the things new for this release are: - More support for the AM33xx platforms from TI - Tegra 124 support, and some updates to older tegra families as well - imx cleanups and updates across the board - A rename of Broadcom's Mobile platforms which were introduced as ARCH_BCM, and turned out to be too broad a name. New name is ARCH_BCM_MOBILE. - A whole bunch of updates and fixes for integrator, making the platform code more modern and switches over to DT-only booting. - Support for two new Renesas shmobile chipsets. Next up for them is more work on consolidation instead of introduction of new non-multiplatform SoCs, we're all looking forward to that! - Misc cleanups for older Samsung platforms, some Allwinner updates, etc" * tag 'soc-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (159 commits) ARM: bcm281xx: Add ARCH_BCM_MOBILE to bcm config ARM: bcm_defconfig: Run "make savedefconfig" ARM: bcm281xx: Add ARCH Timers to config rename ARCH_BCM to ARCH_BCM_MOBILE (mach-bcm) ARM: vexpress: Enable platform-specific options in defconfig ARM: vexpress: Make defconfig work again ARM: sunxi: remove .init_time hooks ARM: imx: enable suspend for imx6sl ARM: imx: ensure dsm_request signal is not asserted when setting LPM ARM: imx6q: call WB and RBC configuration from imx6q_pm_enter() ARM: imx6q: move low-power code out of clock driver ARM: imx: drop extern with function prototypes in common.h ARM: imx: reset core along with enable/disable operation ARM: imx: do not return from imx_cpu_die() call ARM: imx_v6_v7_defconfig: Select CONFIG_PROVE_LOCKING ARM: imx_v6_v7_defconfig: Enable LEDS_GPIO related options ARM: mxs_defconfig: Turn off CONFIG_DEBUG_GPIO ARM: imx: replace imx6q_restart() with mxc_restart() ARM: mach-imx: mm-imx5: Retrieve iomuxc base address from dt ARM: mach-imx: mm-imx5: Retrieve tzic base address from dt ...
