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