Merge tag 'devicetree-for-4.15' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux

Pull DeviceTree updates from Rob Herring:
 "A bigger diffstat than usual with the kbuild changes and a tree wide
  fix in the binding documentation.

  Summary:

   - kbuild cleanups and improvements for dtbs

   - Code clean-up of overlay code and fixing for some long standing
     memory leak and race condition in applying overlays

   - Improvements to DT memory usage making sysfs/kobjects optional and
     skipping unflattening of disabled nodes. This is part of kernel
     tinification efforts.

   - Final piece of removing storing the full path for every DT node.
     The prerequisite conversion of printk's to use device_node format
     specifier happened in 4.14.

   - Sync with current upstream dtc. This brings additional checks to
     dtb compiling.

   - Binding doc tree wide removal of leading 0s from examples

   - RTC binding documentation adding missing devices and some
     consolidation of duplicated bindings

   - Vendor prefix documentation for nutsboard, Silicon Storage
     Technology, shimafuji, Tecon Microprocessor Technologies, DH
     electronics GmbH, Opal Kelly, and Next Thing"
