+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
