Hi Matthias,
just to let you know that Hans has already picked up patches 1-5, and they're on
their way to the media tree:
https://lore.kernel.org/all/af0772c6-7052-ce13-dbf3-d403b06aad02@xs4all.nl
So feel free to pick patches 6 and 7. Though note that these DT changes depend
on those driver patches (commits 1-5) to work.
Thanks,
Nícolas
