Merge tag 'devicetree-for-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux
Pull devicetree updates from Rob Herring:
"DT core:
- Add node lifecycle unit tests
- Add of_property_present() helper aligned with fwnode API
- Print more information on reserved regions on boot
- Update dtc to upstream v1.6.1-66-gabbd523bae6e
- Use strscpy() to instead of strncpy() in DT core
- Add option for schema validation on %.dtb targets
Bindings:
- Add/fix support for listing multiple patterns in DT_SCHEMA_FILES
- Rework external memory controller/bus bindings to properly support
controller specific child node properties
- Convert loongson,ls1x-intc, fcs,fusb302, sil,sii8620, Rockchip
RK3399 PCIe, Synquacer I2C, and Synquacer EXIU bindings to DT
schema format
- Add RiscV SBI PMU event mapping binding
- Add missing contraints on Arm SCMI child node allowed properties
- Add a bunch of missing Socionext UniPhier glue block bindings and
example fixes
- Various fixes for duplicate or conflicting type definitions on DT
properties"
