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.
