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

Adding checks for undocumented compatible strings reveals a bunch of
warnings in the DT binding examples. Fix the cases which are typos, just
a mismatch between the schema and the example, or aren't documented at all.
In a couple of cases, fixing the compatible revealed some schema errors
which are fixed.
There's a bunch of others remaining after this which have bindings, but
those aren't converted to schema yet.

The example for the Silvaco I3C master doesn't match the schema's

Silvaco provide a dual-role I3C master.
Description is rather simple: it needs a register mapping, three
clocks and an interrupt.

Update a little bit the content to match the bus binding, including:
- the node title should have been named after the description done
in the historical i3c.txt file, ie: i3c-master@<address>
- child nodes should be accepted even though the drivers do not currently
support it
- #address-cells and #size-cells are also mandatory and have specific
values

The MIPI I3C HCI (Host Controller Interface) specification defines
a common software driver interface to support compliant MIPI I3C
host controller hardware implementations from multiple vendors.
All that is needed is an I/O area and an interrupt signal;. The hardware
is self-advertising wrt its implementor and implemented capabilities so
there is currently no details that the driver can't figure out on its own.
