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