| title: StarFive JH7110 PLL Clock Generator |
| |
| description: |
| These PLLs are high speed, low jitter frequency synthesizers in the JH7110. |
| Each PLL works in integer mode or fraction mode, with configuration |
| registers in the sys syscon. So the PLLs node should be a child of |
| SYS-SYSCON node. |
| The formula for calculating frequency is |
| Fvco = Fref * (NI + NF) / M / Q1 |
