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.
