  46 *
  47 * With sigma-delta modulation for fractional-N on the audio PLL,
  48 * we have to use specific dividers. This means the variable divider
  49 * can no longer be used, as the audio codec requests the exact clock
  50 * rates we support through this mechanism. So we now hard code the
  51 * variable divider to 1. This means the clock rates will no longer
