Merge tag 'devicetree-for-5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux
Pull Devicetree updates from Rob Herring:
- Improve device links cycle detection and breaking. Add more bindings
for device link dependencies.
- Refactor parsing 'no-map' in __reserved_mem_alloc_size()
- Improve DT unittest 'ranges' and 'dma-ranges' test case to check
differing cell sizes
- Various http to https link conversions
- Add a schema check to prevent 'syscon' from being used by itself
without a more specific compatible
- A bunch more DT binding conversions to schema
