SCSI misc on 20160727

Browse source 
This update includes the usual round of driver updates (fcoe, lpfc,
 ufs, qla2xxx, hisi_sas).  The most important other change is removing
 the flag to allow non-blk_mq on a per host basis (it's unused); there
 is still a global module parameter for all of SCSI just in case.  The
 rest are an assortment of minor fixes and typo updates.

* Universal Flash Storage (UFS) DesignWare Host Controller
DWC_UFS nodes are defined to describe on-chip UFS host controllers and MPHY.
Each UFS controller instance should have its own node.
Required properties:
- compatible : compatible list must contain the PHY type & version:
"snps,g210-tc-6.00-20bit"
"snps,g210-tc-6.00-40bit"
complemented with the Controller IP version:
"snps,dwc-ufshcd-1.40a"
complemented with the JEDEC version:
"jedec,ufs-1.1"
"jedec,ufs-2.0"
- reg : <registers mapping>
- interrupts : <interrupt mapping for UFS host controller IRQ>
Example for a setup using a 1.40a DWC Controller with a 6.00 G210 40-bit TC:
dwc-ufs@d0000000 {
compatible = "snps,g210-tc-6.00-40bit",
"snps,dwc-ufshcd-1.40a",
"jedec,ufs-2.0";
reg = < 0xd0000000 0x10000 >;
interrupts = < 24 >;
};
