Merge tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull ARM SoC-related driver updates from Olof Johansson:
 "Various driver updates for platforms. A bulk of this is smaller fixes
  or cleanups, but some of the new material this time around is:

   - Support for Nvidia Tegra234 SoC

   - Ring accelerator support for TI AM65x

   - PRUSS driver for TI platforms

   - Renesas support for R-Car V3U SoC

   - Reset support for Cortex-M4 processor on i.MX8MQ

  There are also new socinfo entries for a handful of different SoCs and
  platforms"
