 386 * Sub carrier DDA
 387 *
 388 *  I think this works as follows:
 389 *
 390 *  subcarrier freq = pixel_clock * (dda1_inc + dda2_inc / dda2_size) / 4096
 391 *
 392 * Presumably, when dda3 is added in, it gets to adjust the dda2_inc value
 393 *
 394 * So,
 395 *  dda1_ideal = subcarrier/pixel * 4096
 396 *  dda1_inc = floor (dda1_ideal)
 397 *  dda2 = dda1_ideal - dda1_inc
 398 *
 399 *  then pick a ratio for dda2 that gives the closest approximation. If
 400 *  you can't get close enough, you can play with dda3 as well. This
 401 *  seems likely to happen when dda2 is small as the jumps would be larger
 402 *
 403 * To invert this,
 404 *
 405 *  pixel_clock = subcarrier * 4096 / (dda1_inc + dda2_inc / dda2_size)
 406 *
 407 * The constants below were all computed using a 107.520MHz clock

 384 * Sub carrier DDA
 385 *
 386 *  I think this works as follows:
 387 *
 388 *  subcarrier freq = pixel_clock * (dda1_inc + dda2_inc / dda2_size) / 4096
 389 *
 390 * Presumably, when dda3 is added in, it gets to adjust the dda2_inc value
 391 *
 392 * So,
 393 *  dda1_ideal = subcarrier/pixel * 4096
 394 *  dda1_inc = floor (dda1_ideal)
 395 *  dda2 = dda1_ideal - dda1_inc
 396 *
 397 *  then pick a ratio for dda2 that gives the closest approximation. If
 398 *  you can't get close enough, you can play with dda3 as well. This
 399 *  seems likely to happen when dda2 is small as the jumps would be larger
 400 *
 401 * To invert this,
 402 *
 403 *  pixel_clock = subcarrier * 4096 / (dda1_inc + dda2_inc / dda2_size)
