Merge tag 'devicetree-for-5.7' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux
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 :(
