Merge tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC driver updates from Arnd Bergmann: "Driver updates for ARM SoCs, including a couple of newly added drivers: - The Qualcomm external bus interface 2 (EBI2), used in some of their mobile phone chips for connecting flash memory, LCD displays or other peripherals - Secure monitor firmware for Amlogic SoCs, and an NVMEM driver for the EFUSE based on that firmware interface. - Perf support for the AppliedMicro X-Gene performance monitor unit - Reset driver for STMicroelectronics STM32 - Reset driver for SocioNext UniPhier SoCs Aside from these, there are minor updates to SoC-specific bus, clocksource, firmware, pinctrl, reset, rtc and pmic drivers" * tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (50 commits) bus: qcom-ebi2: depend on HAS_IOMEM pinctrl: mvebu: orion5x: Generalise mv88f5181l support for 88f5181 clk: mvebu: Add clk support for the orion5x SoC mv88f5181 dt-bindings: EXYNOS: Add Exynos5433 PMU compatible clocksource: exynos_mct: Add the support for ARM64 perf: xgene: Add APM X-Gene SoC Performance Monitoring Unit driver Documentation: Add documentation for APM X-Gene SoC PMU DTS binding MAINTAINERS: Add entry for APM X-Gene SoC PMU driver bus: qcom: add EBI2 driver bus: qcom: add EBI2 device tree bindings rtc: rtc-pm8xxx: Add support for pm8018 rtc nvmem: amlogic: Add Amlogic Meson EFUSE driver firmware: Amlogic: Add secure monitor driver soc: qcom: smd: Reset rx tail rather than tx memory: atmel-sdramc: fix a possible NULL dereference reset: hi6220: allow to compile test driver on other architectures reset: zynq: add driver Kconfig option reset: sunxi: add driver Kconfig option reset: stm32: add driver Kconfig option reset: socfpga: add driver Kconfig option ...
