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. 60 61 config SCSI_UFSHCD_PLATFORM 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 70 If unsure, say N.
