      When a YUV422 image of size 1920 x 1080 is sent over 4 lanes to the csitx instance 0 with a laneBandSpeed of TIVX_CSITX_LANE_BAND_SPEED_2200_TO_2500_MBPS, the time it takes from queue to dequeue in the driver in 7msec.

      It should take around 3-4 ms as per the below calculation

      Time = (1920 x 1080 x 16 (YUV422 -> 16 bits per pixel)) / (2200 x 10^6 x 4 (no. of data lanes)

      Time = 3. 77 msec

       

      Hence Expected = 3-4 msec

                    Actual = 7 msec
