Merge tag 'devicetree-for-5.13' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux

Pull devicetree updates from Rob Herring:

 - Refactor powerpc and arm64 kexec DT handling to common code. This
   enables IMA on arm64.

 - Add kbuild support for applying DT overlays at build time. The first
   user are the DT unittests.

 - Fix kerneldoc formatting and W=1 warnings in drivers/of/

 - Fix handling 64-bit flag on PCI resources

 - Bump dtschema version required to v2021.2.1

 - Enable undocumented compatible checks for dtbs_check. This allows
   tracking of missing binding schemas.

 - DT docs improvements. Regroup the DT docs and add the example schema
   and DT kernel ABI docs to the doc build.

 - Convert Broadcom Bluetooth and video-mux bindings to schema

 - Add QCom sm8250 Venus video codec binding schema

 - Add vendor prefixes for AESOP, YIC System Co., Ltd, and Siliconfile
   Technologies Inc.

 - Cleanup of DT schema type references on common properties and
   standard unit properties
