  6. Some devices provide a hardware timestamping engine which can
  7. timestamp certain device lines/signals in realtime. It comes with a
  8. benefit for the applications needing accurate timestamping event with
  9. less jitter. This framework provides a generic interface to such HTE
  10. providers and consumer devices.
