libata drivers can define a function (enable_pm) that will
perform hardware specific actions to enable whatever power
management policy the user set up from the scsi sysfs
interface if the driver supports it. This power management
policy will be activated after all disks have been
enumerated
This patch will set the correct bits to turn on Aggressive
Link Power Management (ALPM) for the ahci driver. This
will cause the controller and disk to negotiate a lower
power state for the link when there is no activity (see
the AHCI 1.x spec for details). This feature is mutually
