Perhaps you wanted to append the referred v4l2-compliance output (fixed) ?

As we started doing with other codec driver submission (just did last month for
NXP), can you state which software this driver was tested with ? I have started
receiving feedback from third party that MTK driver support is not reproducible,
I would like to work with you to fix the situation.

regards,
Nicolas
