Merge tag 'devicetree-for-4.16' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux
Pull DeviceTree updates from Rob Herring:
- Convert to use memblock_virt_alloc in DT code which supports
bootmem arches. With this we can remove the arch specific
early_init_dt_alloc_memory_arch() functions.
- Enable running the DT unittests on UML
- Use SPDX license tags on DT files
- Fix early FDT kconfig ifdef logic
- Clean-up unittest Makefile
- Fix function comment for of_irq_parse_raw
- Add missing documentation for linux,initrd-{start,end} properties
- Clean-up of binding examples using uppercase hex
- Add trivial devices W83773G and Infineon TLV493D-A1B6
- Add missing STM32 SoC bindings
- Various small binding doc fixes
