13description: |
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.
