+config SCSI_UFSHCD

+       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.

+       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.

+       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.
