1026 * A note regarding vertical interlaced timings: height refers to the total
1027 * height of the active video frame (= two fields). The blanking timings refer
1028 * to the blanking of each field. So the height of the total frame is
1029 * calculated as follows:
1030 *
1031 * tot_height = height + vfrontporch + vsync + vbackporch +
1032 *                       il_vfrontporch + il_vsync + il_vbackporch
1033 *
1034 * The active height of each field is height / 2.
