Linux/AM5728: VIP input data

Hello,
the problem with colors is fixed. Cr/Cb data was swapped and also pins for Y and CR/Cb were swapped. But there is a black area to the left and above the image. We just connected the data enable signal, but this didn't change anything. Do we have to enable the data enable signal in linux?? Or is there another way to get rid of the black areas?

Dummy subdevice driver just reports a fixed format. Device starts streaming immediately after startup.
