There is an ongoing proposal to rework wcn3990 (bt and wifi) bindings, so we might
want to delay this a bit. Not a strict requirement, since the changes would be
backwards-compatible.
Delaying this patch is not a problem on my side - but if the changes are backwards
compatible, do we really have reasons to delay it?
In any case, I trust your judgement on this: if you want to delay it, I will send
the wcn3990 support after the rework.
Cheers,
