36 tristate "Universal Flash Storage Controller Driver Core"
37 depends on SCSI && SCSI_DMA
39 select DEVFREQ_GOV_SIMPLE_ONDEMAND
42 This selects the support for UFS devices in Linux, say Y and make
43 sure that you know the name of your UFS host adapter (the card
44 inside your computer that "speaks" the UFS protocol, also
45 called UFS Host Controller), because you will be asked for it.
46 The module will be called ufshcd.
48 To compile this driver as a module, choose M here and read
49 <file:Documentation/scsi/ufs.txt>.
50 However, do not compile this as a module if your root file system
51 (the one containing the directory /) is located on a UFS device.
53 config SCSI_UFSHCD_PCI
54 tristate "PCI bus based UFS Controller support"
55 depends on SCSI_UFSHCD && PCI
57 This selects the PCI UFS Host Controller Interface. Select this if
58 you have UFS Host Controller with PCI Interface.
60 If you have a controller with this interface, say Y or M here.
64 config SCSI_UFS_DWC_TC_PCI
65 tristate "DesignWare pci support using a G210 Test Chip"
66 depends on SCSI_UFSHCD_PCI
68 Synopsys Test Chip is a PHY for prototyping purposes.
72 config SCSI_UFSHCD_PLATFORM
73 tristate "Platform bus based UFS Controller support"
74 depends on SCSI_UFSHCD
76 This selects the UFS host controller support. Select this if
77 you have an UFS controller on Platform bus.
79 If you have a controller with this interface, say Y or M here.
83 config SCSI_UFS_CDNS_PLATFORM
84 tristate "Cadence UFS Controller platform driver"
85 depends on SCSI_UFSHCD_PLATFORM
87 This selects the Cadence-specific additions to UFSHCD platform driver.
91 config SCSI_UFS_DWC_TC_PLATFORM
92 tristate "DesignWare platform support using a G210 Test Chip"
93 depends on SCSI_UFSHCD_PLATFORM
95 Synopsys Test Chip is a PHY for prototyping purposes.
100 tristate "QCOM specific hooks to UFS controller platform driver"
101 depends on SCSI_UFSHCD_PLATFORM && ARCH_QCOM
103 This selects the QCOM specific additions to UFSHCD platform driver.
104 UFS host on QCOM needs some vendor specific configuration before
105 accessing the hardware which includes PHY configuration and vendor
108 Select this if you have UFS controller on QCOM chipset.
112 tristate "Hisilicon specific hooks to UFS controller platform driver"
113 depends on (ARCH_HISI || COMPILE_TEST) && SCSI_UFSHCD_PLATFORM
115 This selects the Hisilicon specific additions to UFSHCD platform driver.
117 Select this if you have UFS controller on Hisilicon chipset.
121 bool "Universal Flash Storage BSG device node"
122 depends on SCSI_UFSHCD
123 select BLK_DEV_BSGLIB
125 Universal Flash Storage (UFS) is SCSI transport specification for
126 accessing flash storage on digital cameras, mobile phones and
127 consumer electronic devices.
128 A UFS controller communicates with a UFS device by exchanging
129 UFS Protocol Information Units (UPIUs).
130 UPIUs can not only be used as a transport layer for the SCSI protocol
131 but are also used by the UFS native command set.
132 This transport driver supports exchanging UFS protocol information units
133 with a UFS device. See also the ufshcd driver, which is a SCSI driver
134 that supports UFS devices.
136 Select this if you need a bsg device node for your UFS controller.
