Merge tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM 32-bit SoC platform updates from Olof Johansson: "Most of the SoC updates in this cycle are cleanups and moves to more modern infrastructure: - Davinci was moved to common clock framework - OMAP1-based Amstrad E3 "Superphone" saw a bunch of cleanups to the keyboard interface (bitbanged AT keyboard via GPIO). - Removal of some stale code for Renesas platforms - Power management improvements for i.MX6LL" * tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (112 commits) ARM: uniphier: select RESET_CONTROLLER arm64: uniphier: select RESET_CONTROLLER ARM: uniphier: remove empty Makefile ARM: exynos: Clear global variable on init error path ARM: exynos: Remove outdated maintainer information ARM: shmobile: Always enable ARCH_TIMER on SoCs with A7 and/or A15 ARM: shmobile: r8a7779: hide unused r8a7779_platform_cpu_kill soc: r9a06g032: don't build SMP files for non-SMP config ARM: shmobile: Add the R9A06G032 SMP enabler driver ARM: at91: pm: configure wakeup sources for ULP1 mode ARM: at91: pm: add PMC fast startup registers defines ARM: at91: pm: Add ULP1 mode support ARM: at91: pm: Use ULP0 naming instead of slow clock ARM: hisi: handle of_iomap and fix missing of_node_put ARM: hisi: check of_iomap and fix missing of_node_put ARM: hisi: fix error handling and missing of_node_put ARM: mx5: Set the DBGEN bit in ARM_GPC register ARM: imx51: Configure M4IF to avoid visual artifacts ARM: imx: call imx6sx_cpuidle_init() conditionally for 6sll ARM: imx: fix i.MX6SLL build ...
