config SCSI_UFS_BSG
bool "Universal Flash Storage BSG device node"
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.
config SCSI_UFS_CRYPTO
bool "UFS Crypto Engine Support"
depends on BLK_INLINE_ENCRYPTION
help
Enable Crypto Engine Support in UFS.
Enabling this makes it possible for the kernel to use the crypto
capabilities of the UFS device (if present) to perform crypto
operations on data being transferred to/from the device.
config SCSI_UFS_FAULT_INJECTION
bool "UFS Fault Injection Support"
depends on FAULT_INJECTION
help
Enable fault injection support in the UFS driver. This makes it easier
to test the UFS error handler and abort handler.
config SCSI_UFS_HWMON
bool "UFS Temperature Notification"
depends on SCSI_UFSHCD=HWMON || HWMON=y
help
This provides support for UFS hardware monitoring. If enabled,
a hardware monitoring device will be created for the UFS device.
If unsure, say N.
