Sure, sorry. At times I forget that Android isn't sane in that respect
and can't be used to send mailing list compliant emails.

To be honest I have not really tried it resp. I did actually notice it
bailing out but haven't had time to look closer into it yet. We are
using it with NVIDIA's still platform data based downstream L4T R16.5
and I do know that it works there so I just kind of assumed there will
be a way to make it work in mainline as well. However rather than
adding such platform data I guess migrating it to DT would make more
sense. But until such a migration has been completed I guess we rather
just drop enabling it for now and I will send out a v2 in that respect.
