Merge tag 'devicetree-for-5.12' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux

Pull devicetree updates from Rob Herring:

 - Sync dtc to upstream version v1.6.0-51-g183df9e9c2b9 and build host
   fdtoverlay

 - Add kbuild support to build DT overlays (%.dtbo)

 - Drop NULLifying match table in of_match_device().

   In preparation for this, there are several driver cleanups to use
   (of_)?device_get_match_data().

 - Drop pointless wrappers from DT struct device API

 - Convert USB binding schemas to use graph schema and remove old plain
   text graph binding doc

 - Convert spi-nor and v3d GPU bindings to DT schema

 - Tree wide schema fixes for if/then schemas, array size constraints,
   and undocumented compatible strings in examples

 - Handle 'no-map' correctly for already reserved memblock regions
