This driver runs also on other Tegra SoCs (e.g. Tegra234).
Replace Kconfig dependency on Tegra194 with more generic dependency on
Tegra, and amend the Kconfig help text to reflect the fact that this
driver works on SoCs other than Tegra194.
Fixes: b003fb5c9d ("hte: Add Tegra234 provider")

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

and later systems-on-chip. The driver supports 352 LIC IRQs and 39
|
|
AON GPIOs lines for timestamping in realtime.

The NVIDIA Tegra194 GTE test driver demonstrates how to use HTE
|
|
framework to timestamp GPIO and LIC IRQ lines.
