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.
