1020  * to the blanking of each field. So the height of the total frame is
1021  * calculated as follows:

1023  * tot_height = height + vfrontporch + vsync + vbackporch +
1024  *                       il_vfrontporch + il_vsync + il_vbackporch
1025  *
1026  * The active height of each field is height / 2.
