Why? What is it for? You have entire commit msg for this, instead of
repeating subject.
A nit, subject: drop second/last, redundant "devicetree binding". The
"dt-bindings" prefix is already stating that these are bindings.
See also:
https://elixir.bootlin.com/linux/v6.7-rc8/source/Documentation/devicetree/bindings/submitting-patches.rst#L18
Also drop driver, bindings are not for drivers.

No, first it is not correct (see coding style), second is not even
needed. Drop.

One, same interface for all devices? Nothing SoC specific? You are
making now a contract, so please carefully analyze it internally what it
means.

See DTS coding style.
Node names should be generic. See also an explanation and list of
examples (not exhaustive) in DT specification:

No resources? Nothing here? What is the point except of instantiating
your driver?
