scsi: use host wide tags by default

2015-11-10T01:11:57+00:00

This patch changes the !blk-mq path to the same defaults as the blk-mq
I/O path by always enabling block tagging, and always using host wide
tags.  We've had blk-mq available for a few releases so bugs with
this mode should have been ironed out, and this ensures we get better
coverage of over tagging setup over different configs.

scsi: ufs: make the UFS variant a platform device

2015-11-09T23:00:02+00:00

This change turns the UFS variant (SCSI_UFS_QCOM) into a UFS
a platform device.
In order to do so a few additional changes are required:
1. The ufshcd-pltfrm is no longer serves as a platform device.
   Now it only serves as a group of platform APIs such as PM APIs
   (runtime suspend/resume, system suspend/resume etc), parsers of
   clocks, regulators and pm_levels from DT.
2. What used to be the old platform "probe" is now "only"
   a pltfrm_init() routine, that does exactly the same, but only
   being called by the new probe function of the UFS variant.

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

2015-06-23T22:55:44+00:00

Pull SCSI updates from James Bottomley:
"This is the usual grab bag of driver updates (lpfc, hpsa,
megaraid_sas, cxgbi, be2iscsi) plus an assortment of minor updates.

There is also one new driver: the Cisco snic. The advansys driver has
been rewritten to get rid of the warning about converting it to the
DMA API, the tape statistics patch got in and finally, there's a
resuffle of SCSI header files to separate more cleanly initiator from
target mode (and better share the common definitions)"
