Merge tag 'devicetree-for-5.4' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux
Pull Devicetree updates from Rob Herring:
- a bunch of DT binding conversions to DT schema format
- clean-ups of the Arm idle-states binding
- support a default number of cells in of_for_each_phandle() when the
cells name is missing
- expose dtbs_check and dt_binding_check in the make help
- convert writting-schema.md to ReST
- HiSilicon reset controller binding updates
- add documentation for MT8516 RNG
