This driver is used to stub PHY operations in a driver (USB, SATA). This is useful when the 'client' driver (USB, SATA, ...) uses the PHY framework and there is no actual PHY harwdare to drive. Signed-off-by: Jean-Jacques Hiblot <jjhiblot@ti.com>

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