42 * The Audio PLL is supposed to have 4 outputs: 3 fixed factors from
43 * the base (2x, 4x and 8x), and one variable divider (the one true
44 * pll audio).
45 *
46 * With sigma-delta modulation for fractional-N on the audio PLL,
47 * we have to use specific dividers. This means the variable divider
48 * can no longer be used, as the audio codec requests the exact clock
49 * rates we support through this mechanism. So we now hard code the
50 * variable divider to 1. This means the clock rates will no longer
51 * match the clock names.
