No one discusses here whether you need separate compatible string.
writing bindings and all my talks are (e.g. DTS 101) are clearly
expecting you.

We discuss only the lack of compatibility in terms of DT, how DT sees
compatible devices.

And lack of driver code is clear indication that devices are compatible
in terms how DT understands it. Feel encouraged to bring actual
arguments in commit msgs in the future.
