+ Hardware Timestamping Engine (HTE) Support.
+
+ Some devices provide a hardware timestamping engine which can
+ timestamp certain device lines/signals in realtime. It comes with a
+ benefit for the applications needing accurate timestamping event with
+ less jitter. This framework provides a generic interface to such HTE
+ providers and consumer devices.
+
+ If unsure, say no.

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