Merge tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC driver updates from Olof Johansson: "Driver updates for v4.1. Some of these are for drivers/soc, where we find more and more SoC-specific drivers these days. Some are for other driver subsystems where we have received acks from the appropriate maintainers. The larger parts of this branch are: - MediaTek support for their PMIC wrapper interface, a high-level interface for talking to the system PMIC over a dedicated I2C interface. - Qualcomm SCM driver has been moved to drivers/firmware. It's used for CPU up/down and needs to be in a shared location for arm/arm64 common code. - cleanup of ARM-CCI PMU code. - another set of cleanusp to the OMAP GPMC code" * tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (43 commits) soc/mediatek: Remove unused variables clocksource: atmel-st: select MFD_SYSCON soc: mediatek: Add PMIC wrapper for MT8135 and MT8173 SoCs arm-cci: Fix CCI PMU event validation arm-cci: Split the code for PMU vs driver support arm-cci: Get rid of secure transactions for PMU driver arm-cci: Abstract the CCI400 PMU specific definitions arm-cci: Rearrange code for splitting PMU vs driver code drivers: cci: reject groups spanning multiple HW PMUs ARM: at91: remove useless include clocksource: atmel-st: remove mach/hardware dependency clocksource: atmel-st: use syscon/regmap ARM: at91: time: move the system timer driver to drivers/clocksource ARM: at91: properly initialize timer ARM: at91: at91rm9200: remove deprecated arm_pm_restart watchdog: at91rm9200: implement restart handler watchdog: at91rm9200: use the system timer syscon mfd: syscon: Add atmel system timer registers definition ARM: at91/dt: declare atmel,at91rm9200-st as a syscon soc: qcom: gsbi: Add support for ADM CRCI muxing ...
