 	  chipsets are typically found on most laptops but desktops and
 	  servers now also widely use chipsets supporting low power modes.
 
-	  The value set has the following meanings:
-		0 => Keep firmware settings
-		1 => Maximum performance
-		2 => Medium power
-		3 => Medium power with Device Initiated PM enabled
-		4 => Minimum power
+	  Each policy combines power saving states and features:
+	   - Partial: The Phy logic is powered but is in a reduced power
+                      state. The exit latency from this state is no longer than
+                      10us).
+	   - Slumber: The Phy logic is powered but is in an even lower power
+                      state. The exit latency from this state is potentially
+		      longer, but no longer than 10ms.
+	   - DevSleep: The Phy logic may be powered down. The exit latency from
+	               this state is no longer than 20 ms, unless otherwise
+		       specified by DETO in the device Identify Device Data log.
+	   - HIPM: Host Initiated Power Management (host automatically
+		   transitions to partial and slumber).
+	   - DIPM: Device Initiated Power Management (device automatically
+		   transitions to partial and slumber).
 
-	  Note "Minimum power" is known to cause issues, including disk
-	  corruption, with some disks and should not be used.
+	  The possible values for the default SATA link power management
+	  policies are:
+		0 => Keep firmware settings
+		1 => No power savings (maximum performance)
+		2 => HIPM (Partial)
+		3 => HIPM (Partial) and DIPM (Partial and Slumber)
+		4 => HIPM (Partial and DevSleep) and DIPM (Partial and Slumber)
+		5 => HIPM (Slumber and DevSleep) and DIPM (Partial and Slumber)
+
+	  Excluding the value 0, higher values represent policies with higher
+	  power savings.
