config SCSI_UFSHCD
tristate "Universal Flash Storage Controller Driver Core"
depends on SCSI && SCSI_DMA
select PM_DEVFREQ
select DEVFREQ_GOV_SIMPLE_ONDEMAND
select NLS
help
This selects the support for UFS devices in Linux, say Y and make
sure that you know the name of your UFS host adapter (the card
inside your computer that "speaks" the UFS protocol, also
called UFS Host Controller), because you will be asked for it.
The module will be called ufshcd.
To compile this driver as a module, choose M here and read
<file:Documentation/scsi/ufs.rst>.
However, do not compile this as a module if your root file system
(the one containing the directory /) is located on a UFS device.

help
This selects the PCI UFS Host Controller Interface. Select this if
you have UFS Host Controller with PCI Interface.
If you have a controller with this interface, say Y or M here.
If unsure, say N.

tristate "Platform bus based UFS Controller support"
depends on HAS_IOMEM
help
This selects the UFS host controller support. Select this if
you have an UFS controller on Platform bus.
If you have a controller with this interface, say Y or M here.
If unsure, say N.
config SCSI_UFS_CDNS_PLATFORM
tristate "Cadence UFS Controller platform driver"
depends on SCSI_UFSHCD_PLATFORM
help
This selects the Cadence-specific additions to UFSHCD platform driver.
If unsure, say N.
config SCSI_UFS_DWC_TC_PLATFORM
tristate "DesignWare platform support using a G210 Test Chip"
depends on SCSI_UFSHCD_PLATFORM
help
Synopsys Test Chip is a PHY for prototyping purposes.
If unsure, say N.

help
This selects the QCOM specific additions to UFSHCD platform driver.
UFS host on QCOM needs some vendor specific configuration before
accessing the hardware which includes PHY configuration and vendor
specific registers.
Select this if you have UFS controller on QCOM chipset.
If unsure, say N.
config SCSI_UFS_MEDIATEK
tristate "Mediatek specific hooks to UFS controller platform driver"
depends on SCSI_UFSHCD_PLATFORM && ARCH_MEDIATEK

help
This selects the Mediatek specific additions to UFSHCD platform driver.
UFS host on Mediatek needs some vendor specific configuration before
accessing the hardware which includes PHY configuration and vendor
specific registers.
Select this if you have UFS controller on Mediatek chipset.
If unsure, say N.

This selects driver for TI glue layer for Cadence UFS Host
Controller IP.
Selects this if you have TI platform with UFS controller.
If unsure, say N.
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_EXYNOS
tristate "Exynos specific hooks to UFS controller platform driver"
depends on SCSI_UFSHCD_PLATFORM && (ARCH_EXYNOS || COMPILE_TEST)
help
This selects the Samsung Exynos SoC specific additions to UFSHCD
platform driver. UFS host on Samsung Exynos SoC includes HCI and
UNIPRO layer, and associates with UFS-PHY driver.
Select this if you have UFS host controller on Samsung Exynos SoC.
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_HPB
bool "Support UFS Host Performance Booster"
help
The UFS HPB feature improves random read performance. It caches
L2P (logical to physical) map of UFS to host DRAM. The driver uses HPB
read command by piggybacking physical page number for bypassing FTL (flash
translation layer)'s L2P address translation.
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.
