Merge tag 'scsi-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi 

Pull late SCSI updates from James Bottomley:
 "This is mostly stuff which missed the initial pull.

  There's a new driver: qedi, and some ufs, ibmvscsis and ncr5380
  updates plus some assorted driver fixes and also a fix for the bug
  where if a device goes into a blocked state between configuration and
  sysfs device add (which can be a long time under async probing) it
  would become permanently blocked"

This file documents the NCR53c400 extensions by Kevin Lentin and some

enhancements to the NCR5380 core.



This driver supports both NCR5380 and NCR53c400 cards in port or memory

mapped modes. Currently this driver can only support one of those mapping

modes at a time but it does support both of these chips at the same time.

The next release of this driver will support port & memory mapped cards at

the same time. It should be able to handle multiple different cards in the

same machine.

This driver supports NCR5380 and NCR53c400 and compatible cards in port or

memory mapped modes.



The drivers/scsi/Makefile has an override in it for the most common

NCR53c400 card, the Trantor T130B in its default configuration:

	Port: 0x350

	IRQ : 5

Use of an interrupt is recommended, if supported by the board, as this will

allow targets to disconnect and thereby improve SCSI bus utilization.



If the irq parameter is 254 or is omitted entirely, the driver will probe

for the correct IRQ line automatically. If the irq parameter is 0 or 255

then no IRQ will be used.



The NCR53c400 does not support DMA but it does have Pseudo-DMA which is

supported by the driver.

  dtc_3181e=1  to set up for a Domex Technology Corp 3181E board

  hp_c2502=1   to set up for a Hewlett Packard C2502 board



e.g.

OLD: modprobe g_NCR5380 ncr_irq=5 ncr_addr=0x350 ncr_5380=1

NEW: modprobe g_NCR5380 irq=5 base=0x350 card=0

OLD: modprobe g_NCR5380 ncr_irq=255 ncr_addr=0xc8000 ncr_53c400=1

NEW: modprobe g_NCR5380 irq=255 base=0xc8000 card=1

  for a memory mapped NCR53C400 board with interrupts disabled or

E.g. Trantor T130B in its default configuration:

modprobe g_NCR5380 irq=5 base=0x350 card=1

or alternatively, using the old syntax,

modprobe g_NCR5380 ncr_irq=5 ncr_addr=0x350 ncr_53c400=1



NEW: modprobe g_NCR5380 irq=0,7 base=0x240,0x300 card=3,4

  for two cards: DTC3181 (in non-PnP mode) at 0x240 with no IRQ

             and HP C2502 at 0x300 with IRQ 7

E.g. a port mapped NCR5380 board, driver to probe for IRQ:

modprobe g_NCR5380 base=0x350 card=0

or alternatively,

modprobe g_NCR5380 ncr_addr=0x350 ncr_5380=1



(255 should be specified for no or DMA interrupt, 254 to autoprobe for an 

     IRQ line if overridden on the command line.)

E.g. a memory mapped NCR53C400 board with no IRQ:

modprobe g_NCR5380 irq=255 base=0xc8000 card=1

or alternatively,

modprobe g_NCR5380 ncr_irq=255 ncr_addr=0xc8000 ncr_53c400=1



E.g. two cards, DTC3181 (in non-PnP mode) at 0x240 with no IRQ

and HP C2502 at 0x300 with IRQ 7:

modprobe g_NCR5380 irq=0,7 base=0x240,0x300 card=3,4
