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

 * the base (2x, 4x and 8x), and one variable divider (the one true

 * pll audio).

 *

 * With sigma-delta modulation for fractional-N on the audio PLL,

 * we have to use specific dividers. This means the variable divider

 * can no longer be used, as the audio codec requests the exact clock

 * rates we support through this mechanism. So we now hard code the

 * variable divider to 1. This means the clock rates will no longer

 * match the clock names.
