+ 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
