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"
