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_DWC_TC_PLATFORM
84 tristate "DesignWare platform support using a G210 Test Chip"
85 depends on SCSI_UFSHCD_PLATFORM
87 Synopsys Test Chip is a PHY for prototyping purposes.
92 tristate "QCOM specific hooks to UFS controller platform driver"
93 depends on SCSI_UFSHCD_PLATFORM && ARCH_QCOM
96 This selects the QCOM specific additions to UFSHCD platform driver.
97 UFS host on QCOM needs some vendor specific configuration before
98 accessing the hardware which includes PHY configuration and vendor
101 Select this if you have UFS controller on QCOM chipset.
