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.
