Just to clarify, what I meant is that, using the DT as the authoritative
source of HW description is a way to "add value" to everybody, because both,
3rd-parties and the open-source community get the same information.
This creates the conditions for drivers to exist, with the expectation that
eventually said drivers would be upstreamed.
