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'"
