386 * Sub carrier DDA

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
