A UFS host controller is an electronic component that is able to communicate with a UFS card. UFS host controllers occur in smartphones, laptops, digital cameras and also in cars. The kernel module will be called ufshcd. To compile this driver as a module, choose M here and read <file:Documentation/scsi/ufs.rst>. However, do not compile this as a module if your root file system (the one containing the directory /) is located on a UFS device. if SCSI_UFSHCD source "drivers/ufs/core/Kconfig" source "drivers/ufs/host/Kconfig" endif
