  43          sure that you know the name of your UFS host adapter (the card
  44          inside your computer that "speaks" the UFS protocol, also
  45          called UFS Host Controller), because you will be asked for it.
  46          The module will be called ufshcd.

  48          To compile this driver as a module, choose M here and read
  49          <file:Documentation/scsi/ufs.txt>.
  50          However, do not compile this as a module if your root file system
  51          (the one containing the directory /) is located on a UFS device.

 150          Universal Flash Storage (UFS) is SCSI transport specification for
 151          accessing flash storage on digital cameras, mobile phones and
 152          consumer electronic devices.
 153          A UFS controller communicates with a UFS device by exchanging
 154          UFS Protocol Information Units (UPIUs).
 155          UPIUs can not only be used as a transport layer for the SCSI protocol
 156          but are also used by the UFS native command set.
 157          This transport driver supports exchanging UFS protocol information units
 158          with a UFS device. See also the ufshcd driver, which is a SCSI driver
 159          that supports UFS devices.

 161          Select this if you need a bsg device node for your UFS controller.
