Apparently this is a device driver that uses both V4L2_IN_CAP_DV_TIMINGS
and has discrete frame sizes. That makes no sense. Which device driver is that?

Same question: which device driver uses discrete frame sizes for output?
I am not aware of any, which is the reason this is not implemented in qv4l2.

Please post this as a separate patch.
