13 *PHY* is the abbreviation for physical layer. It is used to connect a device
14 to the physical medium e.g., the USB controller has a PHY to provide functions
17 controllers have PHY functionality embedded into it and others use an external
18 PHY. Other peripherals that use PHY include Wireless LAN, Ethernet,
21 The intention of creating this framework is to bring the PHY drivers spread
22 all over the Linux kernel to drivers/phy to increase code re-use and for
