PHY devices are dedicated hardware that handle the physical 1272e5016fSJean-Jacques Hiblot layer of the protocols in the OSI model. 1372e5016fSJean-Jacques Hiblot PHYs are commonly used for high speed interfaces such as Serial-ATA 1472e5016fSJean-Jacques Hiblot or PCI express. 1572e5016fSJean-Jacques Hiblot The API provides functions to initialize/deinitialize the 1672e5016fSJean-Jacques Hiblot PHY, power on/off the PHY, and reset the PHY.
