384 * Sub carrier DDA

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)
404 *
405 * The constants below were all computed using a 107.520MHz clock
