49 * The Audio PLL is supposed to have 4 outputs: 3 fixed factors from

51 * pll audio).
52 *
53 * With sigma-delta modulation for fractional-N on the audio PLL,
54 * we have to use specific dividers. This means the variable divider
55 * can no longer be used, as the audio codec requests the exact clock
56 * rates we support through this mechanism. So we now hard code the
57 * variable divider to 1. This means the clock rates will no longer
