Merge tag 'scsi-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull SCSI updates from James Bottomley:
"This patch set consists of the usual driver updates (megaraid_sas,
arcmsr, be2iscsi, lpfc, mpt2sas, mpt3sas, qla2xxx, ufs) plus several
assorted fixes and miscellaneous updates (including the
pci_msix_enable_range() changes that have been pending for a while)"

- interrupts : <interrupt mapping for UFS host controller IRQ>
- reg : <registers mapping>
+Optional properties:
+- vdd-hba-supply : phandle to UFS host controller supply regulator node
+- vcc-supply : phandle to VCC supply regulator node
+- vccq-supply : phandle to VCCQ supply regulator node
+- vccq2-supply : phandle to VCCQ2 supply regulator node
+- vcc-supply-1p8 : For embedded UFS devices, valid VCC range is 1.7-1.95V
+ or 2.7-3.6V. This boolean property when set, specifies
+ to use low voltage range of 1.7-1.95V. Note for external
+ UFS cards this property is invalid and valid VCC range is
+ always 2.7-3.6V.
+- vcc-max-microamp : specifies max. load that can be drawn from vcc supply
+- vccq-max-microamp : specifies max. load that can be drawn from vccq supply
+- vccq2-max-microamp : specifies max. load that can be drawn from vccq2 supply
+- <name>-fixed-regulator : boolean property specifying that <name>-supply is a fixed regulator
+
+- clocks : List of phandle and clock specifier pairs
+- clock-names : List of clock input name strings sorted in the same
+ order as the clocks property.
+- freq-table-hz : Array of <min max> operating frequencies stored in the same
+ order as the clocks property. If this property is not
+ defined or a value in the array is "0" then it is assumed
+ that the frequency is set by the parent clock or a
+ fixed rate clock source.
+
+Note: If above properties are not defined it can be assumed that the supply
+regulators or clocks are always on.
+
Example:
ufshc@0xfc598000 {
compatible = "jedec,ufs-1.1";
reg = <0xfc598000 0x800>;
interrupts = <0 28 0>;

+ * hence we require the scsi_device instance to represent this logical unit in

+
+ * We also require the scsi_device instance for "RPMB" (Replay Protected Memory
+ * Block) LU so user space process can control this LU. User space may also
+ * want to have access to BOOT LU.
+
