Dipen Patel 9a75a7cd03 hte: Add Tegra HTE test driver 
The test driver uses IRQ and GPIO lines to timestamp using HTE
subsystem. The patch also adds compilation support in Kconfig and
Makefile.

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 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.
