10 This framework is designed to provide a generic interface for PHY
11 devices. PHY devices are dedicated hardware that handle the physical
12 layer of the protocols in the OSI model.
13 PHYs are commonly used for high speed interfaces such as Serial-ATA
14 or PCI express.
15 The API provides functions to initialize/deinitialize the
16 PHY, power on/off the PHY, and reset the PHY. It's meant to be as
17 compatible as possible with the equivalent framework found in the
18 linux kernel.

48 Support for a no-op PHY driver (stubbed PHY driver).

50 This is useful when a driver uses the PHY framework but no real PHY
51 hardware exists.
