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"

+What: /sys/bus/scsi/drivers/st/debug_flag
+Date: October 2015
+Kernel Version: ?.?
+Contact: shane.seymour@hpe.com
+Description:
+ This file allows you to turn debug output from the st driver
+ off if you write a '0' to the file or on if you write a '1'.
+ Note that debug output requires that the module be compiled
+ with the #define DEBUG set to a non-zero value (this is the
+ default). If DEBUG is set to 0 then this file will not
+ appear in sysfs as its presence is conditional upon debug
+ output support being compiled into the module.

+* 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
+
+Example:
+
+ ufsphy1: ufsphy@0xfc597000 {
+ compatible = "qcom,ufs-phy-qmp-20nm";
+ reg = <0xfc597000 0x800>;

- This option allows you to specify the maximum number of scatter-

- SAFE_PHYS_SEGMENTS. However, it may decreased down to 16.
- Decreasing this parameter will reduce memory requirements

- * Version History
- * ---------------
- *
- * Date Version Description
- * -------- -------- ------------------------------------------------------
- * 04-30-07 02.00.00 Corresponds to Fusion-MPT MPI Specification Rev A.
- * 10-31-07 02.00.01 Fixed name for pMpi2SCSITaskManagementRequest_t.
- * 12-18-07 02.00.02 Modified Task Management Target Reset Method defines.
- * 02-29-08 02.00.03 Added Query Task Set and Query Unit Attention.
- * 03-03-08 02.00.04 Fixed name of struct _MPI2_SCSI_TASK_MANAGE_REPLY.
- * 05-21-08 02.00.05 Fixed typo in name of Mpi2SepRequest_t.
- * 10-02-08 02.00.06 Removed Untagged and No Disconnect values from SCSI IO
- * Control field Task Attribute flags.
- * Moved LUN field defines to mpi2.h because they are
- * common to many structures.
- * 05-06-09 02.00.07 Changed task management type of Query Unit Attention to
- * Query Asynchronous Event.
- * Defined two new bits in the SlotStatus field of the SCSI
- * Enclosure Processor Request and Reply.
- * 10-28-09 02.00.08 Added defines for decoding the ResponseInfo bytes for
- * both SCSI IO Error Reply and SCSI Task Management Reply.
- * Added ResponseInfo field to MPI2_SCSI_TASK_MANAGE_REPLY.
- * Added MPI2_SCSITASKMGMT_RSP_TM_OVERLAPPED_TAG define.
- * 02-10-10 02.00.09 Removed unused structure that had "#if 0" around it.
- * 05-12-10 02.00.10 Added optional vendor-unique region to SCSI IO Request.
- * 11-10-10 02.00.11 Added MPI2_SCSIIO_NUM_SGLOFFSETS define.
- * 02-06-12 02.00.13 Added alternate defines for Task Priority / Command
