7 title: Tegra on chip generic hardware timestamping engine (HTE) provider
10 - Dipen Patel <dipenp@nvidia.com>
13 Tegra SoC has two instances of generic hardware timestamping engines (GTE)
16 timestamp (taken from system counter) in its internal hardware FIFO. It has
18 to enable or disable for the hardware timestamping. The GTE GPIO monitors
