However, many drivers just filled in 0 for the minimum width, height or pixelclock frequency. This can cause timings with e.g. 0 as width and height to be accepted, which will in turn lead to a potential division by zero. Fill in proper values are minimum boundaries. 640x350 was chosen since it is the smallest resolution in v4l2-dv-timings.h. Same for 13 MHz as the lowest pixelclock frequency (it's slightly below the minimum of 13.5 MHz in the v4l2-dv-timings.h header).
