    Subject[PATCH v2 0/3] ahci: fix boot/resume COMRESET failures
    Date
    This series addresses regression problems with

    commit 7faa33da9b7add01db9f1ad92c6a5d9145e940a7
    ahci: start engine only during soft/hard resets

    Because the fix provided by the above commit caused COMRESET failures and
    10 second boot-time/resume-time hangs for certain DVD drives, we need to
    make the fix conditional to certain devices/platforms. Add a flag for this.

    Brian

    v2: change flag name to AHCI_HFLAG_DELAY_ENGINE, write more detailed
    comments

    v1: flag named AHCI_HFLAG_STRICT_SPEC

    Brian Norris (3):
    ahci: add AHCI_HFLAG_DELAY_ENGINE host flag
    ahci: move AHCI_HFLAGS() macro to ahci.h
    ahci_platform: add STRICT_AHCI platform type
