	  The module will be called ufshcd.

	  To compile this driver as a module, choose M here and read
	  <file:Documentation/scsi/ufs.txt>.
	  However, do not compile this as a module if your root file system

	select BLK_DEV_BSGLIB
	help
	  Universal Flash Storage (UFS) is SCSI transport specification for
	  accessing flash storage on digital cameras, mobile phones and
	  consumer electronic devices.
	  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
	  that supports UFS devices.

	  Select this if you need a bsg device node for your UFS controller.
	  If unsure, say N.
