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"
