Merge tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC platform updates from Arnd Bergmann: "Most of the commits are for defconfig changes, to enable newly added drivers or features that people have started using. For the changed lines lines, we have mostly cleanups, the affected platforms are OMAP, Versatile, EP93xx, Samsung, Broadcom, i.MX, and Actions. The largest single change is the introduction of the TI "sysc" bus driver, with the intention of cleaning up more legacy code. Two new SoC platforms get added this time: - Allwinner R40 is a modernized version of the A20 chip, now with a Quad-Core ARM Cortex-A7. According to the manufacturer, it is intended for "Smart Hardware" - Broadcom Hurricane 2 (Aka Strataconnect BCM5334X) is a family of chips meant for managed gigabit ethernet switches, based around a Cortex-A9 CPU. Finally, we gain SMP support for two platforms: Renesas R-Car E2 and Amlogic Meson8/8b, which were previously added but only supported uniprocessor operation" * tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (118 commits) ARM: multi_v7_defconfig: Select RPMSG_VIRTIO as module ARM: multi_v7_defconfig: enable CONFIG_GPIO_UNIPHIER arm64: defconfig: enable CONFIG_GPIO_UNIPHIER ARM: meson: enable MESON_IRQ_GPIO in Kconfig for meson8b ARM: meson: Add SMP bringup code for Meson8 and Meson8b ARM: smp_scu: allow the platform code to read the SCU CPU status ARM: smp_scu: add a helper for powering on a specific CPU dt-bindings: Amlogic: Add Meson8 and Meson8b SMP related documentation ARM: OMAP3: Delete an unnecessary variable initialisation in omap3xxx_hwmod_init() ARM: OMAP3: Use common error handling code in omap3xxx_hwmod_init() ARM: defconfig: select the right SX150X driver arm64: defconfig: Enable QCOM_IOMMU arm64: Add ThunderX drivers to defconfig arm64: defconfig: Enable Tegra PCI controller cpufreq: imx6q: Move speed grading check to cpufreq driver arm64: defconfig: re-enable Qualcomm DB410c USB ARM: configs: stm32: Add MDMA support in STM32 defconfig ARM: imx: Enable cpuidle for i.MX6DL starting at 1.1 bus: ti-sysc: Fix unbalanced pm_runtime_enable by adding remove bus: ti-sysc: mark PM functions as __maybe_unused ...
