SCSI for-linus on 20161222

Browse Source 
This is mostly stuff which missed the initial pull.  There's a new
 driver: qedi, 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.
@ -47,22 +45,24 @@ These old-style parameters can support only one card:
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

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

NEW: modprobe g_NCR5380 irq=255 base=0xc8000 card=1
for a memory mapped NCR53C400 board with interrupts disabled or

modprobe g_NCR5380 base=0x350 card=0

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
(255 should be specified for no or DMA interrupt, 254 to autoprobe for an
IRQ line if overridden on the command line.)

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