Hi Ludo,
sorry for the long delay!

For now I guess it would be the best to not package the actual driver
and rely on the one that is merged into linux-libre.  I reduced the
patches to only add inputattach and the service type for it.

Tim.

Sounds good!

I applied both patches and expounded a bit the documentation in a
followup commit.

Thank you!
