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, these contain various things that touch
the drivers/ directory but got merged through arm-soc for practical
reasons.
For the most part, this is now related to power management
controllers, which have not yet been abstracted into a separate
subsystem, and typically require some code in drivers/soc or arch/arm
to control the power domains.
Another large chunk here is a rework of the NVIDIA Tegra USB3.0
support, which was surprisingly tricky and took a long time to get
done.
Finally, reset controller handling as always gets merged through here
as well"
