Merge tag 'devicetree-for-4.7' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux
Pull devicetree updates from Rob Herring:
- Rewrite of the unflattening code to avoid recursion and lessen the
stack usage.
- Rewrite of the phandle args parsing code to get rid of the fixed args
size. This is needed for IOMMU code.
- Sync to latest dtc which adds more dts style checking. These
warnings are enabled with "W=1" compiles.
- Tegra documentation updates related to the above warnings.
- A bunch of spelling and other doc fixes.
- Various vendor prefix additions.
