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.
