My bookmark to elixir.bootling does not work, so could not paste
specific line. Now it works, so:

https://elixir.bootlin.com/linux/v6.11-rc3/source/Documentation/devicetree/bindings/submitting-patches.rst#L79

The rule was/is:
1. Binding for typical devices always go via subsystem tree, with the
driver changes.
There can be exceptions from above, e.g. some subsystems do not pick up
bindings, so Rob does. But how patches are organized is not an exception
- it is completely normal workflow.

2. DTS *always* goes via SoC maintainer. DTS cannot go via any other
driver subsystem tree. There is no exception here. There cannot be an
exception, because it would mean the hardware depends on driver, which
is obviously false.

Best regards,
Krzysztof
