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_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.

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.
