I don't know how mixed mode works, but according to Allwinner it gives best results, so they use it exclusively. Currently this mode is also hardcoded here. For each interleaved frame queued, this driver produces 2 deinterlaced frames. Deinterlaced frames are based on 2 consequtive output buffers, except for the first 2, where same output buffer is given to peripheral as current and previous. There is no documentation for this core, so register layout and fixed values were taken from BSP driver. I'm not sure if maximum size of the image unit is capable to process is governed by size of "flag" buffers, frequency or it really is some HW limitation. Currently driver can process full HD image in ~15ms (7.5ms for each capture buffer), which allows to process 1920x1080@60i video smoothly in real time.
