Merge tag 'devicetree-for-4.18' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux

Pull DeviceTree updates from Rob Herring:

 - Sync dtc with upstream version v1.4.6-21-g84e414b0b5bc. This adds new
   warnings which are either fixed or disabled by default (enabled with
   W=1).

 - Validate an untrusted offset in DT overlay function
   update_usages_of_a_phandle_reference

 - Fix a use after free error of_platform_device_destroy

 - Fix an off by 1 string errors in unittest

 - Avoid creating a struct device for OPP nodes

 - Update DT specific submitting-patches.txt with patch content and
   subject requirements.

 - Move some bindings to their proper subsystem locations

 - Add vendor prefixes for Kaohsiung, SiFive, Avnet, Wi2Wi, Logic PD,
   and ArcherMind

 - Add documentation for "no-gpio-delays" property in FSI bus GPIO
   master

 - Add compatible for r8a77990 SoC ravb ethernet block

 - More wack-a-mole removal of 'status' property in examples
