  35config SCSI_UFSHCD
  36        tristate "Universal Flash Storage Controller Driver Core"
  37        depends on SCSI && SCSI_DMA
  38        ---help---
  39        This selects the support for UFS devices in Linux, say Y and make
  40          sure that you know the name of your UFS host adapter (the card
  41          inside your computer that "speaks" the UFS protocol, also
  42          called UFS Host Controller), because you will be asked for it.
  43          The module will be called ufshcd.
  44
  45          To compile this driver as a module, choose M here and read
  46          <file:Documentation/scsi/ufs.txt>.
  47          However, do not compile this as a module if your root file system
  48          (the one containing the directory /) is located on a UFS device.

  51        tristate "PCI bus based UFS Controller support"
  52        depends on SCSI_UFSHCD && PCI
  53        ---help---
  54        This selects the PCI UFS Host Controller Interface. Select this if
  55        you have UFS Host Controller with PCI Interface.
  56
  57          If you have a controller with this interface, say Y or M here.
  58
  59          If unsure, say N.

  62        tristate "Platform bus based UFS Controller support"
  63        depends on SCSI_UFSHCD
  64        ---help---
  65        This selects the UFS host controller support. Select this if
  66        you have an UFS controller on Platform bus.
  67
  68        If you have a controller with this interface, say Y or M here.
  69
