820 will be called xilinx_i2c.
823 tristate "XLR I2C support"
826 This driver enables support for the on-chip I2C interface of
827 the Netlogic XLR/XLS MIPS processors.
829 This driver can also be built as a module. If so, the module
830 will be called i2c-xlr.

842 comment "External I2C/SMBus adapter drivers"
844 config I2C_DIOLAN_U2C
845 tristate "Diolan U2C-12 USB adapter"
848 If you say yes to this option, support will be included for Diolan
849 U2C-12, a USB to I2C interface.
851 This driver can also be built as a module. If so, the module
852 will be called i2c-diolan-u2c.
855 tristate "Parallel port adapter"
860 This supports parallel port I2C adapters such as the ones made by
861 Philips or Velleman, Analog Devices evaluation boards, and more.
862 Basically any adapter using the parallel port as an I2C bus with
863 no extra chipset is supported by this driver, or could be.
865 This driver is a replacement for (and was inspired by) an older
866 driver named i2c-philips-par. The new driver supports more devices,
867 and makes it easier to add support for new devices.
869 An adapter type parameter is now mandatory. Please read the file
870 Documentation/i2c/busses/i2c-parport for details.
872 Another driver exists, named i2c-parport-light, which doesn't depend
873 on the parport driver. This is meant for embedded systems. Don't say
874 Y here if you intend to say Y or M there.
876 This support is also available as a module. If so, the module
877 will be called i2c-parport.
879 config I2C_PARPORT_LIGHT
880 tristate "Parallel port adapter (light)"
884 This supports parallel port I2C adapters such as the ones made by
885 Philips or Velleman, Analog Devices evaluation boards, and more.
886 Basically any adapter using the parallel port as an I2C bus with
887 no extra chipset is supported by this driver, or could be.
889 This driver is a light version of i2c-parport. It doesn't depend
890 on the parport driver, and uses direct I/O access instead. This
891 might be preferred on embedded systems where wasting memory for
892 the clean but heavy parport handling is not an option. The
893 drawback is a reduced portability and the impossibility to
894 daisy-chain other parallel port devices.
896 Don't say Y here if you said Y or M to i2c-parport. Saying M to
897 both is possible but both modules should not be loaded at the same
900 This support is also available as a module. If so, the module
901 will be called i2c-parport-light.
903 config I2C_ROBOTFUZZ_OSIF
904 tristate "RobotFuzz Open Source InterFace USB adapter"
907 If you say yes to this option, support will be included for the
908 RobotFuzz Open Source InterFace USB to I2C interface.
910 This driver can also be built as a module. If so, the module
911 will be called i2c-osif.
914 tristate "TAOS evaluation module"
920 This supports TAOS evaluation modules on serial port. In order to
921 use this driver, you will need the inputattach tool, which is part
922 of the input-utils package.
926 This support is also available as a module. If so, the module
927 will be called i2c-taos-evm.
930 tristate "Tiny-USB adapter"
933 If you say yes to this option, support will be included for the
934 i2c-tiny-usb, a simple do-it-yourself USB to I2C interface. See
935 http://www.harbaum.org/till/i2c_tiny_usb for hardware details.
937 This driver can also be built as a module. If so, the module
938 will be called i2c-tiny-usb.
940 config I2C_VIPERBOARD
941 tristate "Viperboard I2C master support"
942 depends on MFD_VIPERBOARD && USB
944 Say yes here to access the I2C part of the Nano River
945 Technologies Viperboard as I2C master.
946 See viperboard API specification and Nano
947 River Tech's viperboard.h for detailed meaning
948 of the module parameters.
950 comment "Other I2C/SMBus bus drivers"
953 tristate "Acorn IOC/IOMD I2C bus support"
954 depends on ARCH_ACORN
958 Say yes if you want to support the I2C bus on Acorn platforms.
960 If you don't know, say Y.
963 tristate "Elektor ISA card"
964 depends on ISA && HAS_IOPORT_MAP && BROKEN_ON_SMP
967 This supports the PCF8584 ISA bus I2C adapter. Say Y if you own
970 This support is also available as a module. If so, the module
971 will be called i2c-elektor.
974 tristate "PCA9564/PCA9665 on an ISA bus"
979 This driver supports ISA boards using the Philips PCA9564/PCA9665
980 parallel bus to I2C bus controller.
982 This driver can also be built as a module. If so, the module
983 will be called i2c-pca-isa.
985 This device is almost undetectable and using this driver on a
986 system which doesn't have this device will result in long
987 delays when I2C/SMBus chip drivers are loaded (e.g. at boot
988 time). If unsure, say N.
991 tristate "SiByte SMBus interface"
992 depends on SIBYTE_SB1xxx_SOC
994 Supports the SiByte SOC on-chip I2C interfaces (2 channels).
997 tristate "NatSemi SCx200 I2C using GPIO pins (DEPRECATED)"
998 depends on SCx200_GPIO
1001 Enable the use of two GPIO pins of a SCx200 processor as an I2C bus.
1003 If you don't know what to do here, say N.
1005 This support is also available as a module. If so, the module
1006 will be called scx200_i2c.
1008 This driver is deprecated and will be dropped soon. Use i2c-gpio
1009 (or scx200_acb) instead.
1011 config SCx200_I2C_SCL
1012 int "GPIO pin used for SCL"
1013 depends on SCx200_I2C

1017 also be specified with a module parameter.
1019 config SCx200_I2C_SDA
1020 int "GPIO pin used for SDA"
1021 depends on SCx200_I2C
1024 Enter the GPIO pin number used for the SSA signal. This value can
1025 also be specified with a module parameter.
1028 tristate "Geode ACCESS.bus support"
1029 depends on X86_32 && PCI
1031 Enable the use of the ACCESS.bus controllers on the Geode SCx200 and
1032 SC1100 processors and the CS5535 and CS5536 Geode companion devices.
1034 If you don't know what to do here, say N.
1036 This support is also available as a module. If so, the module
1037 will be called scx200_acb.
