[PATCH 0/4] SATA device runtime power off

Add support for hard disk runtime power off and differentiate
system pm with runtime pm messages.

The patch "libata: pm: differentiate system and runtime pm for ata port"
is the same as the previously seperated sent one:
http://marc.info/?l=linux-ide&m=134614386932721&w=2
I included it into this patch set because patch "libata: acpi: respect
may_power_off flag" is based on top of it.

The patch "scsi: pm: add may_power_off flag" also appears in another
patchset intended for scsi subsystem, they are identical.

Aaron Lu (4):
  libata: pm: differentiate system and runtime pm for ata port
  libata: acpi: set can_power_off for both ODD and HD
  scsi: pm: add may_power_off flag
  libata: acpi: respect may_power_off flag
