Merge tag 'devicetree-for-5.8' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux
Pull devicetree updates from Rob Herring:
- Convert various DT (non-binding) doc files to ReST
- Various improvements to device link code
- Fix __of_attach_node_sysfs refcounting bug
- Add support for 'memory-region-names' with reserved-memory binding
- Vendor prefixes for Protonic Holland, BeagleBoard.org, Alps, Check
Point, Würth Elektronik, U-Boot, Vaisala, Baikal Electronics,
Shanghai Awinic Technology Co., MikroTik, Silex Insight
- A bunch more binding conversions to DT schema. Only 3K to go.
- Add a minimum version check for schema tools
- Treewide dropping of 'allOf' usage with schema references. Not needed
in new json-schema spec.
- Some formatting clean-ups of schemas
