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"
