| 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. |
