 * Notation clarification: in h/w documentation PLL base outputs (except PLLA
 * output) are denoted as PllX_OUT0, and the seconadry PLL outputs (if any)
 * after fractional dividers are denoted as PllX_OUT1, PllX_OUT2, .... However,
 * no h/w name is defined for the base PLLA output, and the output of the PLLA
 * secondary divider is marked as PllA_OUT0 (not PllA_OUT1). Threfore, we use
 * PllA1 (not PllA0) to denote base PLLA clock.
