This is part of patchset series described in [T]. This is the second take of implement-ata_link patchset. This patchset contains 17 patches which can be categorized as follows. #01-02: prep #03-04: implement ata_link #05-08: make libata deal with link instead of port #09-11: misc link stuff (link init, reset_tries, ata_link_abort()) #12-17: add ap->pmp_link[] and update 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. Changes from the last take[L] are. * updated to fit new #upstream * ata_eh_handle_dev_fail() is separated out from ata_eh_recover() to ease making EH batch later. * Link resume handling udpated. * Power Management is linkified. This patchset is against upstream (309bade002e9226781c2d7a015340d0089e399b5) + [1] hp-poll patchset, take #2 Thanks. -- tejun [T] http://article.gmane.org/gmane.linux.ide/11927 [L] http://article.gmane.org/gmane.linux.ide/10106 [1] http://article.gmane.org/gmane.linux.ide/11862
