It's in staging, nobody has registered any interest, the company behind
the hardware as publicly said they won't continue development, and
there's no documentation. I think that meets the bar for dropping the
driver. In the very unlikely case someone would want to revive it, the
source code will live in git history.

We can easily do that when applying.
