Bindings are before users.

Please use subject prefixes matching the subsystem. You can get them for
example with `git log --oneline -- DIRECTORY_OR_FILE` on the directory
your patch is touching.
There is no file extension in prefixes.

No, use existing, generic properties. Open other bindings for this.

Also, none of these were tested. I am not going to review such untested
code.

It does not look like you tested the bindings, at least after quick
look. Please run `make dt_binding_check` (see
Documentation/devicetree/bindings/writing-schema.rst for instructions).
Maybe you need to update your dtschema and yamllint.

Best regards,
Krzysztof
