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

Pull final round of SCSI updates from James Bottomley:
 "Sorry for the delay in this patch which was mostly caused by getting
  the merger of the mpt2/mpt3sas driver, which was seen as an essential
  item of maintenance work to do before the drivers diverge too much.
  Unfortunately, this caused a compile failure (detected by linux-next),
  which then had to be fixed up and incubated.

  In addition to the mpt2/3sas rework, there are updates from pm80xx,
  lpfc, bnx2fc, hpsa, ipr, aacraid, megaraid_sas, storvsc and ufs plus
  an assortment of changes including some year 2038 issues, a fix for a
  remove before detach issue in some drivers and a couple of other minor
  issues"

+* Qualcomm Technologies Inc Universal Flash Storage (UFS) PHY
+
+UFSPHY nodes are defined to describe on-chip UFS PHY hardware macro.
+Each UFS PHY node should have its own node.
+
+To bind UFS PHY with UFS host controller, the controller node should
+contain a phandle reference to UFS PHY node.
+
+Required properties:
+- compatible        : compatible list, contains "qcom,ufs-phy-qmp-20nm"
+		      or "qcom,ufs-phy-qmp-14nm" according to the relevant phy in use.
+- reg               : should contain PHY register address space (mandatory),
+- reg-names         : indicates various resources passed to driver (via reg proptery) by name.
+                      Required "reg-names" is "phy_mem".
+- #phy-cells        : This property shall be set to 0
+- vdda-phy-supply   : phandle to main PHY supply for analog domain
+- vdda-pll-supply   : phandle to PHY PLL and Power-Gen block power supply
+- 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. "ref_clk_src", "ref_clk",
+		      "tx_iface_clk" & "rx_iface_clk" are mandatory but
+		      "ref_clk_parent" is optional
+
+Optional properties:
+- vdda-phy-max-microamp : specifies max. load that can be drawn from phy supply
+- vdda-pll-max-microamp : specifies max. load that can be drawn from pll supply
+- vddp-ref-clk-supply   : phandle to UFS device ref_clk pad power supply
+- vddp-ref-clk-max-microamp : specifies max. load that can be drawn from this supply
+- vddp-ref-clk-always-on : specifies if this supply needs to be kept always on
