12  * The EP93xx has two external crystal oscillators.  To generate the
13  * required high-frequency clocks, the processor uses two phase-locked-
14  * loops (PLLs) to multiply the incoming external clock signal to much
15  * higher frequencies that are then divided down by programmable dividers
16  * to produce the needed clocks.  The PLLs operate independently of one
17  * another.
