menuconfig HTE bool "Hardware Timestamping Engine (HTE) Support" help 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.

config HTE_TEGRA194 tristate "NVIDIA Tegra194 HTE Support" depends on (ARCH_TEGRA_194_SOC || COMPILE_TEST) depends on GPIOLIB help 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 lines for timestamping in realtime.

config HTE_TEGRA194_TEST tristate "NVIDIA Tegra194 HTE Test" depends on (HTE_TEGRA194 || COMPILE_TEST) help The NVIDIA Tegra194 GTE test driver demonstrates how to use HTE framework to timestamp GPIO and LIC IRQ lines.
