+ *  I think this works as follows:
+ *
+ *  subcarrier freq = pixel_clock * (dda1_inc + dda2_inc / dda2_size) / 4096
+ *
+ * Presumably, when dda3 is added in, it gets to adjust the dda2_inc value
+ *
+ * So,
+ *  dda1_ideal = subcarrier/pixel * 4096
+ *  dda1_inc = floor (dda1_ideal)
+ *  dda2 = dda1_ideal - dda1_inc
+ *
+ *  then pick a ratio for dda2 that gives the closest approximation. If
+ *  you can't get close enough, you can play with dda3 as well. This
+ *  seems likely to happen when dda2 is small as the jumps would be larger
+ *
+ * To invert this,
+ *
+ *  pixel_clock = subcarrier * 4096 / (dda1_inc + dda2_inc / dda2_size)
