+title: Ingenic SoCs CGU devicetree bindings
+
+description: |
+  The CGU in an Ingenic SoC provides all the clocks generated on-chip. It
+  typically includes a variety of PLLs, multiplexers, dividers & gates in order
+  to provide many different clock signals derived from only 2 external source
+  clocks.
