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.
