Merge tag 'devicetree-for-5.1' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux
Pull Devicetree updates from Rob Herring:
- Fix a unittest failure on UML. Preparation for converting to kunit
test framework.
- Add annotations to dtx_diff output
- Fix unittest reporting of expected error
- Move DMA configuration for virtual devices into the driver that needs
it (s5p-mfc)
- Vendor prefixes for feiyang and techstar
- Convert ARM GIC, GICv3, and L2x0 to DT schema
- Add r8a7778/9 HSCIF serial bindings
