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
