| 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. |
