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