+* 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

- *
- *  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
- *                      Priority to match SAM-4.
- *  07-10-12  02.00.14  Added MPI2_SCSIIO_CONTROL_SHIFT_DATADIRECTION.
- *  04-09-13  02.00.15  Added SCSIStatusQualifier field to MPI2_SCSI_IO_REPLY,
- *                      replacing the Reserved4 field.

- *  04-30-07  02.00.00  Corresponds to Fusion-MPT MPI Specification Rev A.
- *  06-26-07  02.00.01  Added Clear All Persistent Operation to SAS IO Unit
- *                      Control Request.
- *  10-02-08  02.00.02  Added Set IOC Parameter Operation to SAS IO Unit Control
- *                      Request.
- *  10-28-09  02.00.03  Changed the type of SGL in MPI2_SATA_PASSTHROUGH_REQUEST
- *                      to MPI2_SGE_IO_UNION since it supports chained SGLs.
- *  05-12-10  02.00.04  Modified some comments.
- *  08-11-10  02.00.05  Added NCQ operations to SAS IO Unit Control.

- *  Version History
- *  ---------------
- *
- *  Date      Version   Description
- *  --------  --------  ------------------------------------------------------
- *  04-30-07  02.00.00  Corresponds to Fusion-MPT MPI Specification Rev A.
- *  12-18-07  02.00.01  Added Diagnostic Buffer Post and Diagnostic Release
- *                      structures and defines.
- *  02-29-08  02.00.02  Modified various names to make them 32-character unique.
- *  05-06-09  02.00.03  Added ISTWI Read Write Tool and Diagnostic CLI Tool.
- *  07-30-09  02.00.04  Added ExtendedType field to DiagnosticBufferPost request
- *                      and reply messages.
- *                      Added MPI2_DIAG_BUF_TYPE_EXTENDED.
- *                      Incremented MPI2_DIAG_BUF_TYPE_COUNT.
- *  05-12-10  02.00.05  Added Diagnostic Data Upload tool.
- *  08-11-10  02.00.06  Added defines that were missing for Diagnostic Buffer
- *                      Post Request.
- *  05-25-11  02.00.07  Added Flags field and related defines to
