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