Vinayak Holikattie0eca632013-02-25 21:44:33 +0530[diff] [blame]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.
46
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.
