Last time I heard from Jagan he reported that the LP11 timeout issue
was caused by:

    media: ov5640: Add horizontal and vertical totals

    All the initialization arrays are changing the horizontal and vertical
    totals for some value.

    In order to clean up the driver, and since we're going to need that value
    later on, let's introduce in the ov5640_mode_info structure the horizontal
    and vertical total sizes, and move these out of the bytes array.
