Devicetree updates for v5.13:
- Refactoring 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 -----BEGIN PGP SIGNATURE----- iQJEBAABCgAuFiEEktVUI4SxYhzZyEuo+vtdtY28YcMFAmCIYdgQHHJvYmhAa2Vy bmVsLm9yZwAKCRD6+121jbxhw/PKEACkOCWDnLSY9U7w1uGDHr6UgXIWOY9j8bYy 2pTvDrVa6KZphT6yGU/hxrOk8Mqh5AMd2vUhO2OCoyyl/priTv+Ktqo+bikvJZLa MQm3JnrLpPy/GetdmVD8wq1l+FoeOSTnRIJqRxInsd8UFVpZImtP22ELox6KgGiv keVHIrjsHU/HpafK3w8wHCLikCZk+1Gl6pL/QgFDv2FaaCTKW16Dt64dPqYm49Xk j7YMMQWl+3NJ9ywZV0+PMbl9udi3EjGm5Ap5VfKzpj53Nh07QObg/QtH/1sj0HPo apyW7jAyQFyLytbjxzFL/tljtOeW/5rZos1GWThZ326e+Y0mTKUTDZShvNplfjIf e26FvVi7gndWlRSr30Ia5gdNFAx72IkpJUAuypBXgb+qNPchBJjAXLn9tcIcg/k+ 2R6BIB7SkVLpgTnJ1Bq1+PRqkKM+ggACdJNJIUApj44xoiG01vtGDGRaFuIio+Ch HT4aBbic4kLvagm8VzuiIF/sL7af5pntzArcyOfQTaZ92DyGI2C0j90rK3yPRIYM u9qX/24t1SXiUji74QpoQFzt/+Egy5hYXMJOJJSywUjKf7DBhehqklTjiJRQHKm6 0DJ/n8q4lNru8F0Y4keKSuYTfHBstF7fS3UTH/rUmBAbfEwkvZe6B29KQbs+7aph GTw+jeoR5Q== =rF27 -----END PGP SIGNATURE----- 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.
