All the SKUs of Kodama share much of their .dts, as evident of the
inclusion of a common .dtsi file. However this scheme builds each
dtb file as a complete device tree.
To deduplicate this, make the common .dtsi file a .dts file, and the
SKU specific .dts files into .dtso overlay source files. Have the build
system assemble the SKU specific .dtb files from these components.
The final composite .dtb files increase in size by around 54 kB, or 22.5%,
due to the inclusion of symbols and fixup tables, and extra phandle
properties. This could be slightly reduced by dropping the symbol and
fixup tables after the overlays are fully applied if desired.
However if the bootloader can assemble the end .dtb using the base .dtb
and overlays, and only those are counted, then the combined size
decreases by around 165 kB, or 68.7%.

Hi,
This is part of the work I'm looking into and will present at EOSS 2024
in Seattle [1].
The idea is to reorganize device trees so that devices within a common
family, instead of having a common .dtsi file, will share a base DTB
and apply one or more overlays on top. This allows an upstream [2] or
downstream [3] bundling script to be able to deduplicate the base DTB
and get some space savings, however minor they are compared to the
kernel binary executable.
This patch gives a simple conversion, but we could even look into
converting the entire MT8183 Kukui family, which are all based on the
"Kukui" hardware reference design.
There are some issues, hence the RFC:
1. The base .dtb doesn't have a valid board compatible string sequence
yet. Suppose we used the sequence
"google,kodama", "mediatek,mt8183"
for the base .dtb in this conversion, would that be acceptable? The
base .dtb would act like a fallback.
2. The composite .dtb files grow in size substantially, due to the base
.dtb file being built with overlay support. The symbols and fixup
tables could be trimmed out with `fdtput`, but there will still be
extra phandles, and also nodes with /omit-if-no-ref/ that would
have been removed.
For this I could maybe come up with a program to minify the DTB. That
would also work for existing composite .dtb files in-tree.
3. Such a scheme would require more awareness on the maintainer's part,
and of the .dtbo authors. The maintainer needs to be aware of how
the composite .dtb files are assembled. The authors need to know that
certain constructs, such as /delete-property/ or /delete-node/, won't
work.

My bot found new DTB warnings on the .dts files added or changed in this
series.
Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.
If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:
pip3 install dtschema --upgrade
