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
