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)"

@@ -8,9 +8,50 @@ Required properties:
- 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.
