    The v4l2_dv_timings_cap struct is used to do sanity checks when setting and
    enumerating DV timings, ensuring that only valid timings as per the HW
    capabilities are allowed.
    
    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).
