The SATA controller core supports both PARTIAL and SLUMBER low-power states, as described in the SATA standard specification (revision 2.6). These modes allow power savings by powering down part of SATA_PHY and gating off the clocks to the link layer. The port power control module is used to enter and exit these modes, which can have the normal functional clocks gated off.
