| 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. |
