config SCSI_UFSHCD
tristate "Universal Flash Storage Controller Driver Core"
depends on SCSI && SCSI_DMA
select PM_DEVFREQ
select DEVFREQ_GOV_SIMPLE_ONDEMAND
---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.txt>.
However, do not compile this as a module if your root file system
(the one containing the directory /) is located on a UFS device.
config SCSI_UFSHCD_PCI
tristate "PCI bus based UFS Controller support"
depends on SCSI_UFSHCD && PCI
---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.
config SCSI_UFS_DWC_TC_PCI
tristate "DesignWare pci support using a G210 Test Chip"
depends on SCSI_UFSHCD_PCI
---help---
Synopsys Test Chip is a PHY for prototyping purposes.
If unsure, say N.
config SCSI_UFSHCD_PLATFORM
tristate "Platform bus based UFS Controller support"
depends on SCSI_UFSHCD
---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_QCOM
tristate "QCOM specific hooks to UFS controller platform driver"
depends on SCSI_UFSHCD_PLATFORM && ARCH_QCOM
select PHY_QCOM_UFS
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_QCOM_ICE
bool "QCOM specific hooks to Inline Crypto Engine for UFS driver"
depends on SCSI_UFS_QCOM && CRYPTO_DEV_QCOM_ICE
help
This selects the QCOM specific additions to support Inline Crypto
Engine (ICE).
ICE accelerates the crypto operations and maintains the high UFS
performance.
Select this if you have ICE supported for UFS on QCOM chipset.
If unsure, say N.
config SCSI_UFS_TEST
tristate "Universal Flash Storage host controller driver unit-tests"
depends on SCSI_UFSHCD && IOSCHED_TEST
default m
---help---
This adds UFS Host controller unit-test framework.
The UFS unit-tests register as a block device test utility to
the test-iosched and will be initiated when the test-iosched will
be chosen to be the active I/O scheduler.
config SCSI_UFSHCD_CMD_LOGGING
bool "Universal Flash Storage host controller driver layer command logging support"
depends on SCSI_UFSHCD
help
This selects the UFS host controller driver layer command logging.
UFS host controller driver layer command logging records all the
command information sent from UFS host controller for debugging
purpose.
Select this if you want above mentioned debug information captured.
If unsure, say N.
config SCSI_UFSHCD_HPB_ACTIVATE
int "Activate HPB Host-aware Performance Booster"
depends on SCSI_UFSHCD
default 1
help
Activate or deactive UFSHPB v1.3.5 test driver
