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.rst>.
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
77 This selects the UFS host controller support. Select this if
78 you have an UFS controller on Platform bus.
80 If you have a controller with this interface, say Y or M here.
84 config SCSI_UFS_CDNS_PLATFORM
85 tristate "Cadence UFS Controller platform driver"
86 depends on SCSI_UFSHCD_PLATFORM
88 This selects the Cadence-specific additions to UFSHCD platform driver.
92 config SCSI_UFS_DWC_TC_PLATFORM
93 tristate "DesignWare platform support using a G210 Test Chip"
94 depends on SCSI_UFSHCD_PLATFORM
96 Synopsys Test Chip is a PHY for prototyping purposes.
101 tristate "QCOM specific hooks to UFS controller platform driver"
102 depends on SCSI_UFSHCD_PLATFORM && ARCH_QCOM
103 select QCOM_SCM if SCSI_UFS_CRYPTO
104 select RESET_CONTROLLER
106 This selects the QCOM specific additions to UFSHCD platform driver.
107 UFS host on QCOM needs some vendor specific configuration before
108 accessing the hardware which includes PHY configuration and vendor
111 Select this if you have UFS controller on QCOM chipset.
114 config SCSI_UFS_MEDIATEK
115 tristate "Mediatek specific hooks to UFS controller platform driver"
116 depends on SCSI_UFSHCD_PLATFORM && ARCH_MEDIATEK
118 select RESET_TI_SYSCON
120 This selects the Mediatek specific additions to UFSHCD platform driver.
121 UFS host on Mediatek needs some vendor specific configuration before
122 accessing the hardware which includes PHY configuration and vendor
125 Select this if you have UFS controller on Mediatek chipset.
130 tristate "Hisilicon specific hooks to UFS controller platform driver"
131 depends on (ARCH_HISI || COMPILE_TEST) && SCSI_UFSHCD_PLATFORM
133 This selects the Hisilicon specific additions to UFSHCD platform driver.
135 Select this if you have UFS controller on Hisilicon chipset.
138 config SCSI_UFS_TI_J721E
139 tristate "TI glue layer for Cadence UFS Controller"
140 depends on OF && HAS_IOMEM && (ARCH_K3 || COMPILE_TEST)
142 This selects driver for TI glue layer for Cadence UFS Host
145 Selects this if you have TI platform with UFS controller.
149 bool "Universal Flash Storage BSG device node"
150 depends on SCSI_UFSHCD
151 select BLK_DEV_BSGLIB
153 Universal Flash Storage (UFS) is SCSI transport specification for
154 accessing flash storage on digital cameras, mobile phones and
155 consumer electronic devices.
156 A UFS controller communicates with a UFS device by exchanging
157 UFS Protocol Information Units (UPIUs).
158 UPIUs can not only be used as a transport layer for the SCSI protocol
159 but are also used by the UFS native command set.
160 This transport driver supports exchanging UFS protocol information units
161 with a UFS device. See also the ufshcd driver, which is a SCSI driver
162 that supports UFS devices.
164 Select this if you need a bsg device node for your UFS controller.
167 config SCSI_UFS_EXYNOS
168 tristate "EXYNOS specific hooks to UFS controller platform driver"
169 depends on SCSI_UFSHCD_PLATFORM && (ARCH_EXYNOS || COMPILE_TEST)
171 This selects the EXYNOS specific additions to UFSHCD platform driver.
172 UFS host on EXYNOS includes HCI and UNIPRO layer, and associates with
175 Select this if you have UFS host controller on EXYNOS chipset.
178 config SCSI_UFS_CRYPTO
179 bool "UFS Crypto Engine Support"
180 depends on SCSI_UFSHCD && BLK_INLINE_ENCRYPTION
182 Enable Crypto Engine Support in UFS.
183 Enabling this makes it possible for the kernel to use the crypto
184 capabilities of the UFS device (if present) to perform crypto
185 operations on data being transferred to/from the device.
188 bool "Support UFS Host Performance Booster"
189 depends on SCSI_UFSHCD
191 The UFS HPB feature improves random read performance. It caches
192 L2P (logical to physical) map of UFS to host DRAM. The driver uses HPB
193 read command by piggybacking physical page number for bypassing FTL (flash
194 translation layer)'s L2P address translation.
196 config SCSI_UFS_FAULT_INJECTION
197 bool "UFS Fault Injection Support"
198 depends on SCSI_UFSHCD && FAULT_INJECTION
200 Enable fault injection support in the UFS driver. This makes it easier
201 to test the UFS error handler and abort handler.
