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:
 "These are updates for platform specific code on 32-bit ARM machines,
  essentially anything that can not (yet) be expressed using DT files.

  Noteworthy changes include:

   - Added support for the TI DRA71x family of SoCs in mach-omap2, this
     is an new variant of the the DRA72x/DRA74x automotive infotainment
     chips we already supported for a while.

   - Added support for the ST STM32F746 SoC, the first Cortex-M7 based
     microcontroller we support, related to the smaller STM32F4 family.

   - Renesas adds support for r8a7743 and r8a7745 in mach-shmobile, see
     http://elinux.org/RZ-G

   - SMP is now supported on the OX820 platform

   - A lot of code in mach-omap2 gets removed as a follow-up to removing
     support for board files in the previous release

   - Davinci has some new work to improve USB support

   - For i.MX, the performance monitor now supports profiling the memory
     controller using 'perf'"
