I'm not an expert in this DT scripts and why it complains. Maybe it
complains because the "samsung,exynos-ppmu" is defined in the .txt
file... (?)
Although, in general looks OK.

I think the warning (triggered by DT_CHECKER_FLAGS=-m) can be ignored
because it complains about compatible in example which is not present in
the bindings. Usually it means someone wrote example not matching the
bindings (e.g. a typo in compatible) but here it is on purpose.

Ultimately, it will mean the binding is undocumented (or a typo). But
right now, it means the binding is undocumented with a schema. It's
off by default because there's still about 80 warnings. It's turned on
for the bot so we don't add more. So please don't ignore it.

By "Ignore" I meant here that it is a false positive, so it can be
ignored. The warning is about compatible "samsung,exynos-ppmu" used in
the example. However this exynos-ppmu is not part of this bindings and
is documented elsewhere:
Documentation/devicetree/bindings/devfreq/event/exynos-ppmu.txt


Best regards,
Krzysztof
