    Linus Torvalds authored
    Pull hardware timestamping subsystem from Thierry Reding:
     "This contains the new HTE (hardware timestamping engine) subsystem
      that has been in the works for a couple of months now.
    
      The infrastructure provided allows for drivers to register as hardware
      timestamp providers, while consumers will be able to request events
      that they are interested in (such as GPIOs and IRQs) to be timestamped
      by the hardware providers.
    
      Note that this currently supports only one provider, but there seems
      to be enough interest in this functionality and we expect to see more
      drivers added once this is merged"
    
    [ Linus Walleij mentions the Intel PMC in the Elkhart and Tiger Lake
      platforms as another future timestamp provider ]
