| 41 | This selects the support for UFS devices in Linux, say Y and make |
| 42 | sure that you know the name of your UFS host adapter (the card |
| 43 | inside your computer that "speaks" the UFS protocol, also |
| 44 | called UFS Host Controller), because you will be asked for it. |
| 45 | The module will be called ufshcd. |

| 47 | To compile this driver as a module, choose M here and read |
| 48 | <file:Documentation/scsi/ufs.txt>. |
| 49 | However, do not compile this as a module if your root file system |
| 50 | (the one containing the directory /) is located on a UFS device. |
