Merge tag 'armsoc-late' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC late DT updates from Arnd Bergmann:
"These updates have been kept in a separate branch mostly because they
rely on updates to the respective clk drivers to keep the shared
header files in sync.
This includes two branches for arm64 dt updates, both following up on
earlier changes for the same platforms that are already merged:
Samsung:
- add USB3 support in Exynos7
- minor PM related updates
Amlogic:
- new machines: WeTek Set-top-boxes
- various devices added to DT
There are also a couple of bugfixes that trickled in since the start
of the merge window:
- The moxart_defconfig was not building the intended platform
- CPU-hotplug was broken on ux500
- Coresight was broken on Juno (never worked)"
