How to differentiate between selective suspend and global suspend

Hi,
    I have implemented bus_suspend entry point of hc_driver of my OHCI
complaint host controller. This entry point is called when i do
selective roothub interface suspend as well as when i do global suspend
( suspend to disk ). So is there any way to differentiate between
selective suspend of roothub interface and global suspend ( suspend to
disk ) for both of which my bus_suspend entry point is getting called ?
Please suggest.
 
Thanks and regards,
Rasmit.

Suspend-to-Disk is a system state, not a driver state;
you seem confused about things.

There is no distinction between suspending the root hub and
suspending all its downstream ports; how could you do one
without the other???

Someone wants to rewrite/redesign selective suspend, I'm afraid.
