09574cca - hte: Add Tegra194 HTE kernel provider

Fri, 22 Apr 2022 20:52:14 +0000

hte: Add Tegra194 HTE kernel providerTegra194 device has multiple HTE instances also known as GTE (GenericHardware Timestamping Engine) which can timestamp subset of SoC linesand signals. This provider driver focuses on IRQ and GPIO lines andexposes timestamping ability on those lines to the consumers throughHTE subsystem.Also, with this patch, added:- documentation about this provider and its capabilities atDocumentation/hte.- Compilation support in Makefile and KconfigSigned-off-by: Dipen Patel Reported-by: kernel test robot Signed-off-by: Thierry Reding List of files: /linux-6.15/drivers/hte/Makefile

31ab09b4 - drivers: Add hardware timestamp engine (HTE) subsystem

Fri, 22 Apr 2022 20:52:13 +0000

drivers: Add hardware timestamp engine (HTE) subsystemSome devices can timestamp system lines/signals/Buses in real-timeusing the hardware counter or other hardware means which can givefiner granularity and help avoid jitter introduced by softwaretimestamping. To utilize such functionality, this patchset createsHTE subsystem where devices can register themselves as providers sothat the consumers devices can request specific line from theproviders. The patch also adds compilation support in Makefile andmenu 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.Signed-off-by: Dipen Patel Reported-by: kernel test robot Signed-off-by: Thierry Reding List of files: /linux-6.15/drivers/hte/Makefile
