Merge tag 'devicetree-for-4.17' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux

Pull DeviceTree updates from Rob Herring:

 - Sync dtc to upstream version v1.4.6-9-gaadd0b65c987. This adds a
   bunch more warnings (hidden behind W=1).

 - Build dtc lexer and parser files instead of using shipped versions.

 - Rework overlay apply API to take an FDT as input and apply overlays
   in a single step.

 - Add a phandle lookup cache. This improves boot time by hundreds of
   msec on systems with large DT.

 - Add trivial mcp4017/18/19 potentiometers bindings.

 - Remove VLA stack usage in DT code.
