+	  A UFS controller communicates with a UFS device by exchanging
+	  UFS Protocol Information Units (UPIUs).
+	  UPIUs can not only be used as a transport layer for the SCSI protocol
+	  but are also used by the UFS native command set.
+	  This transport driver supports exchanging UFS protocol information units
+	  with a UFS device. See also the ufshcd driver, which is a SCSI driver
