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

21	  Enable this option for integrated hardware timestamping engine also
22	  known as generic timestamping engine (GTE) support on NVIDIA Tegra194
23	  systems-on-chip. The driver supports 352 LIC IRQs and 39 AON GPIOs
