* phy: add a NO-OP phy driverJean-Jacques Hiblot2017-07-281-0/+16
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>
