scsi: use host wide tags by default

2015-11-10T01:11:57Z

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

2015-11-09T23:00:02Z

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.
