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
