Bug Description
A new host-controlled SATA interface power state, DevSleep, and a new host-controlled HW signal, DEVSLP, which together enable a SATA host and device to enter an ultra-low interface power state, including the possibility of completely powering down host and device PHYs.
The DevSleep interface power state and DEVSLP signal are enabled/disabled by a new SATA feature, Device Sleep, controlled by the SET FEATURES command.
