14 The iProc clock controller manages clocks that are common to the iProc family.
15 An SoC from the iProc family may have several PLLs, e.g., ARMPLL, GENPLL,
16 LCPLL0, MIPIPLL, and etc., all derived from an onboard crystal. Each PLL
17 comprises of several leaf clocks
18
19 ASIU clocks are a special case. These clocks are derived directly from the
20 reference clock of the onboard crystal.
