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 * tag 'devicetree-for-5.13' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux: (64 commits) powerpc: If kexec_build_elf_info() fails return immediately from elf64_load() powerpc: Free fdt on error in elf64_load() of: overlay: Fix kerneldoc warning in of_overlay_remove() of: linux/of.h: fix kernel-doc warnings of/pci: Add IORESOURCE_MEM_64 to resource flags for 64-bit memory addresses dt-bindings: bcm4329-fmac: add optional brcm,ccode-map docs: dt: update writing-schema.rst references dt-bindings: media: venus: Add sm8250 dt schema of: base: Fix spelling issue with function param 'prop' docs: dt: Add DT API documentation of: Add missing 'Return' section in kerneldoc comments of: Fix kerneldoc output formatting docs: dt: Group DT docs into relevant sub-sections docs: dt: Make 'Devicetree' wording more consistent docs: dt: writing-schema: Include the example schema in the doc build docs: dt: writing-schema: Remove spurious indentation dt-bindings: Fix reference in submitting-patches.rst to the DT ABI doc dt-bindings: ddr: Add optional manufacturer and revision ID to LPDDR3 dt-bindings: media: video-interfaces: Drop the example devicetree: bindings: clock: Minor typo fix in the file armada3700-tbg-clock.txt ...
