Merge tag 'cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM soc general cleanups from Olof Johansson:
"This is a large branch that contains a handful of different cleanups:
- Fixing up the I/O space remapping on PCI on ARM. This is a series
from Rob Herring that restructures how all pci devices allocate I/O
space, and it's part of the work to allow multiplatform kernels.
- A number of cleanup series for OMAP, moving and removing some
headers, sparse irq rework and in general preparation for
multiplatform.
- Final removal of all non-DT boards for Tegra, it is now
device-tree-only!
- Removal of a stale platform, nxp4008. It's an old mobile chipset
that is no longer in use, and was very likely never really used
with a mainline kernel. We have not been able to find anyone
interested in keeping it around in the kernel.
- Removal of the legacy dmaengine driver on tegra
+ A handful of other things that I haven't described above."
Fix up some conflicts with the staging tree (and because nxp4008 was
removed)
