Merge tag 'devicetree-for-4.7' of git://git.kernel.org/pub/scm/linux/kernel/git/robh...

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.
