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

STMicroelectronics STM32 Platforms Device Tree Bindings



Each device tree must specify which STM32 SoC it uses,

using one of the following compatible strings:

  st,stm32f469

These properties hold the physical start and end address of an initrd that's

loaded by the bootloader. Note that linux,initrd-start is inclusive, but

linux,initrd-end is exclusive.
