description:

13
  Digital Phase-Locked Loop (DPLL) device is used for precise clock

14
  synchronization in networking and telecom hardware. The device can

15
  have one or more channels (DPLLs) and one or more physical input and

16
  output pins. Each DPLL channel can either produce pulse-per-clock signal

17
  or drive ethernet equipment clock. The type of each channel can be

18
  indicated by dpll-types property.
