1011 * A note regarding vertical interlaced timings: height refers to the total
1012 * height of the active video frame (= two fields). The blanking timings refer
1013 * to the blanking of each field. So the height of the total frame is
1014 * calculated as follows:
1015 *
1016 * tot_height = height + vfrontporch + vsync + vbackporch +
1017 * il_vfrontporch + il_vsync + il_vbackporch
1018 *
1019 * The active height of each field is height / 2.
