349 | * Sub carrier DDA | |
350 | * | |
351 | * I think this works as follows: | |
352 | * | |
353 | * subcarrier freq = pixel_clock * (dda1_inc + dda2_inc / dda2_size) / 4096 | |
354 | * | |
355 | * Presumably, when dda3 is added in, it gets to adjust the dda2_inc value | |
356 | * | |
357 | * So, | |
358 | * dda1_ideal = subcarrier/pixel * 4096 | |
359 | * dda1_inc = floor (dda1_ideal) | |
360 | * dda2 = dda1_ideal - dda1_inc | |
361 | * | |
362 | * then pick a ratio for dda2 that gives the closest approximation. If | |
363 | * you can't get close enough, you can play with dda3 as well. This | |
364 | * seems likely to happen when dda2 is small as the jumps would be larger | |
365 | * | |
366 | * To invert this, | |
367 | * | |
368 | * pixel_clock = subcarrier * 4096 / (dda1_inc + dda2_inc / dda2_size) | |
