Merge tag 'armsoc-late' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC late updates from Olof Johansson:
"A couple of late-merged changes that would be useful to get in this
merge window:
- Driver support for reset of audio complex on Meson platforms. The
audio driver went in this merge window, and these changes have been
in -next for a while (just not in our tree).
- Power management fixes for IOMMU on Rockchip platforms, getting
closer to kexec working on them, including Chromebooks.
- Another pass updating "arm,psci" -> "psci" for some properties that
have snuck in since last time it was done"
