drivers: Add hardware timestamp engine (HTE) subsystem Some devices can timestamp system lines/signals/Buses in real-time using the hardware counter or other hardware means which can give finer granularity and help avoid jitter introduced by software timestamping. To utilize such functionality, this patchset creates HTE subsystem where devices can register themselves as providers so that the consumers devices can request specific line from the providers. The patch also adds compilation support in Makefile and menu options in Kconfig. The provider does following: - Registers chip with the framework. - Provides translation hook to convert logical line id. - Provides enable/disable, request/release callbacks. - Pushes timestamp data to HTE subsystem. The consumer does following: - Initializes line attribute. - Gets HTE timestamp descriptor. - Requests timestamp functionality. - Puts HTE timestamp descriptor.

hte: Add Tegra194 HTE kernel provider Tegra194 device has multiple HTE instances also known as GTE (Generic Hardware Timestamping Engine) which can timestamp subset of SoC lines and signals. This provider driver focuses on IRQ and GPIO lines and exposes timestamping ability on those lines to the consumers through HTE subsystem. Also, with this patch, added: - documentation about this provider and its capabilities at Documentation/hte. - Compilation support in Makefile and Kconfig Signed-off-by: Dipen Patel <dipenp@nvidia.com> Reported-by: kernel test robot <lkp@intel.com> Signed-off-by: Thierry Reding <treding@nvidia.com> 2022-04-22 23:52:14 +03:00			`obj-$(CONFIG_HTE_TEGRA194) += hte-tegra194.o`
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.
