This is part of patchset series described in [T]. This is the first take of implement-ata_link patchset. This patchset contains 14 patches which can be categorized as follows. #01 : prep #02-03: implement ata_link #04-06: make parts of libata deal with link instead of port #07-09: misc link stuff (link init, reset_tries, ata_link_abort()) #10-14: add ap->pm_link[] and update parts of libata to deal with multiple links ata_link abstracts PHY and sits between ata_port and ata_device. The following attributes are moved to ata_link from ata_port. - active command state (active_tag, sactive) - [hw_]sata_spd_limit - eh_info and eh_context - device array With above and a few extra fields, a link can fully host attached devices including qc management and EH/hotplug. This patchset makes libata ready to handle PM links.
