Pull devicetree updates from Rob Herring:

 - Unit test for overlays with GPIO hogs

 - Improve dma-ranges parsing to handle dma-ranges with multiple entries

 - Update dtc to upstream version v1.6.0-2-g87a656ae5ff9

 - Improve overlay error reporting

 - Device link support for power-domains and hwlocks bindings

 - Add vendor prefixes for Beacon, Topwise, ENE, Dell, SG Micro, Elida,
   PocketBook, Xiaomi, Linutronix, OzzMaker, Waveshare Electronics, and
   ITE Tech

 - Add deprecated Marvell vendor prefix 'mrvl'

 - A bunch of binding conversions to DT schema continues. Of note, the
   common serial and USB connector bindings are converted.

 - Add more Arm CPU compatibles

 - Drop Mark Rutland as DT maintainer :(
