- ---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_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.
