[SCSI] aic94xx: new driver
This is the end point of the separate aic94xx driver based on the original driver and transport class from Luben Tuikov <ltuikov@yahoo.com> The log of the separate development is: Alexis Bruemmer: o aic94xx: fix hotplug/unplug for expanderless systems o aic94xx: disable split completion timer/setting by default o aic94xx: wide port off expander support o aic94xx: remove various inline functions o aic94xx: use bitops o aic94xx: remove queue comment o aic94xx: remove sas_common.c o aic94xx: sas remove depot's o aic94xx: use available list_for_each_entry_safe_reverse() o aic94xx: sas header file merge James Bottomley: o aic94xx: fix TF_TMF_NO_CTX processing o aic94xx: convert to request_firmware interface o aic94xx: fix hotplug/unplug o aic94xx: add link error counts to the expander phys o aic94xx: add transport class phy reset capability o aic94xx: remove local_attached flag o Remove README o Fixup Makefile variable for libsas rename o Rename sas->libsas o aic94xx: correct return code for sas_discover_event o aic94xx: use parent backlink port o aic94xx: remove channel abstraction o aic94xx: fix routing algorithms o aic94xx: add backlink port o aic94xx: fix cascaded expander properties o aic94xx: fix sleep under lock o aic94xx: fix panic on module removal in complex topology o aic94xx: make use of the new sas_port o rename sas_port to asd_sas_port o Fix for eh_strategy_handler move o aic94xx: move entirely over to correct transport class formulation o remove last vestages of sas_rphy_alloc() o update for eh_timed_out move o Preliminary expander support for aic94xx o sas: remove event thread o minor warning cleanups o remove last vestiges of id mapping arrays o Further updates o Convert aic94xx over entirely to the transport class end device and o update aic94xx/sas to use the new sas transport class end device o [PATCH] aic94xx: attaching to the sas transport class o Add missing completion removal from prior patch o [PATCH] aic94xx: attaching to the sas transport class o Build fixes from akpm Jeff Garzik: o [scsi aic94xx] Remove ->owner from PCI info table Luben Tuikov: o initial aic94xx driver Mike Anderson: o aic94xx: fix panic on module insertion o aic94xx: stub out SATA_DEV case o aic94xx: compile warning cleanups o aic94xx: sas_alloc_task o aic94xx: ref count update o aic94xx nexus loss time value o [PATCH] aic94xx: driver assertion in non-x86 BIOS env Randy Dunlap: o libsas: externs not needed Robert Tarte: o aic94xx: sequence patch - fixes SATA support Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
