Merge tag 'devicetree-for-4.8' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux
Pull DeviceTree updates from Rob Herring:
- remove most of_platform_populate() calls in arch code. Now the DT
core code calls it in the default case and platforms only need to
call it if they have special needs
- use pr_fmt on all the DT core print statements
- CoreSight binding doc improvements to block name descriptions
- add dt_to_config script which can parse dts files and list
corresponding kernel config options
- fix memory leak hit with a PowerMac DT
- correct a bunch of STMicro compatible strings to use the correct
vendor prefix
- fix DA9052 PMIC binding doc to match what is actually used in dts
files
