Merge tag 'devicetree-for-4.12' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux

Pull DeviceTree updates from Rob Herring:

 - fix sparse warnings in drivers/of/

 - add more overlay unittests

 - update dtc to v1.4.4-8-g756ffc4f52f6. This adds more checks on dts
   files such as unit-address formatting and stricter character sets for
   node and property names

 - add a common DT modalias function

 - move trivial-devices.txt up and out of i2c dir

 - ARM NVIC interrupt controller binding

 - vendor prefixes for Sensirion, Dioo, Nordic, ROHM

 - correct some binding file locations
