389 * Sub carrier DDA

391 * I think this works as follows:
392 *
393 * subcarrier freq = pixel_clock * (dda1_inc + dda2_inc / dda2_size) / 4096
394 *
395 * Presumably, when dda3 is added in, it gets to adjust the dda2_inc value
396 *
397 * So,
398 * dda1_ideal = subcarrier/pixel * 4096
399 * dda1_inc = floor (dda1_ideal)
400 * dda2 = dda1_ideal - dda1_inc
401 *
402 * then pick a ratio for dda2 that gives the closest approximation. If
403 * you can't get close enough, you can play with dda3 as well. This
404 * seems likely to happen when dda2 is small as the jumps would be larger
405 *
406 * To invert this,
407 *
408 * pixel_clock = subcarrier * 4096 / (dda1_inc + dda2_inc / dda2_size)
409 *
410 * The constants below were all computed using a 107.520MHz clock
