815 will be called i2c-rcar.
817 comment "External I2C/SMBus adapter drivers"
819 config I2C_DIOLAN_U2C
820 tristate "Diolan U2C-12 USB adapter"
823 If you say yes to this option, support will be included for Diolan
824 U2C-12, a USB to I2C interface.
826 This driver can also be built as a module. If so, the module
827 will be called i2c-diolan-u2c.
830 tristate "Parallel port adapter"
835 This supports parallel port I2C adapters such as the ones made by
836 Philips or Velleman, Analog Devices evaluation boards, and more.
837 Basically any adapter using the parallel port as an I2C bus with
838 no extra chipset is supported by this driver, or could be.
840 This driver is a replacement for (and was inspired by) an older
841 driver named i2c-philips-par. The new driver supports more devices,
842 and makes it easier to add support for new devices.
844 An adapter type parameter is now mandatory. Please read the file
845 Documentation/i2c/busses/i2c-parport for details.
847 Another driver exists, named i2c-parport-light, which doesn't depend
848 on the parport driver. This is meant for embedded systems. Don't say
849 Y here if you intend to say Y or M there.
851 This support is also available as a module. If so, the module
852 will be called i2c-parport.
854 config I2C_PARPORT_LIGHT
855 tristate "Parallel port adapter (light)"
859 This supports parallel port I2C adapters such as the ones made by
860 Philips or Velleman, Analog Devices evaluation boards, and more.
861 Basically any adapter using the parallel port as an I2C bus with
862 no extra chipset is supported by this driver, or could be.
864 This driver is a light version of i2c-parport. It doesn't depend
865 on the parport driver, and uses direct I/O access instead. This
866 might be preferred on embedded systems where wasting memory for
867 the clean but heavy parport handling is not an option. The
868 drawback is a reduced portability and the impossibility to
869 daisy-chain other parallel port devices.
871 Don't say Y here if you said Y or M to i2c-parport. Saying M to
872 both is possible but both modules should not be loaded at the same
875 This support is also available as a module. If so, the module
876 will be called i2c-parport-light.
878 config I2C_ROBOTFUZZ_OSIF
879 tristate "RobotFuzz Open Source InterFace USB adapter"
882 If you say yes to this option, support will be included for the
883 RobotFuzz Open Source InterFace USB to I2C interface.
885 This driver can also be built as a module. If so, the module
886 will be called i2c-osif.
889 tristate "TAOS evaluation module"
895 This supports TAOS evaluation modules on serial port. In order to
896 use this driver, you will need the inputattach tool, which is part
897 of the input-utils package.
901 This support is also available as a module. If so, the module
902 will be called i2c-taos-evm.
905 tristate "Tiny-USB adapter"
908 If you say yes to this option, support will be included for the
909 i2c-tiny-usb, a simple do-it-yourself USB to I2C interface. See
910 http://www.harbaum.org/till/i2c_tiny_usb for hardware details.
912 This driver can also be built as a module. If so, the module
913 will be called i2c-tiny-usb.
915 config I2C_VIPERBOARD
916 tristate "Viperboard I2C master support"
917 depends on MFD_VIPERBOARD && USB
919 Say yes here to access the I2C part of the Nano River
920 Technologies Viperboard as I2C master.
921 See viperboard API specification and Nano
922 River Tech's viperboard.h for detailed meaning
923 of the module parameters.
925 comment "Other I2C/SMBus bus drivers"
928 tristate "Acorn IOC/IOMD I2C bus support"
929 depends on ARCH_ACORN
933 Say yes if you want to support the I2C bus on Acorn platforms.
935 If you don't know, say Y.
938 tristate "Elektor ISA card"
939 depends on ISA && HAS_IOPORT && BROKEN_ON_SMP
942 This supports the PCF8584 ISA bus I2C adapter. Say Y if you own
945 This support is also available as a module. If so, the module
946 will be called i2c-elektor.
949 tristate "PCA9564/PCA9665 on an ISA bus"
954 This driver supports ISA boards using the Philips PCA9564/PCA9665
955 parallel bus to I2C bus controller.
957 This driver can also be built as a module. If so, the module
958 will be called i2c-pca-isa.
960 This device is almost undetectable and using this driver on a
961 system which doesn't have this device will result in long
962 delays when I2C/SMBus chip drivers are loaded (e.g. at boot
963 time). If unsure, say N.
966 tristate "SiByte SMBus interface"
967 depends on SIBYTE_SB1xxx_SOC
969 Supports the SiByte SOC on-chip I2C interfaces (2 channels).
972 tristate "NatSemi SCx200 I2C using GPIO pins (DEPRECATED)"
973 depends on SCx200_GPIO
976 Enable the use of two GPIO pins of a SCx200 processor as an I2C bus.
978 If you don't know what to do here, say N.
980 This support is also available as a module. If so, the module
981 will be called scx200_i2c.
983 This driver is deprecated and will be dropped soon. Use i2c-gpio
984 (or scx200_acb) instead.
986 config SCx200_I2C_SCL
987 int "GPIO pin used for SCL"
988 depends on SCx200_I2C
991 Enter the GPIO pin number used for the SCL signal. This value can
992 also be specified with a module parameter.
994 config SCx200_I2C_SDA
995 int "GPIO pin used for SDA"
996 depends on SCx200_I2C
999 Enter the GPIO pin number used for the SSA signal. This value can
1000 also be specified with a module parameter.
1003 tristate "Geode ACCESS.bus support"
1004 depends on X86_32 && PCI
1006 Enable the use of the ACCESS.bus controllers on the Geode SCx200 and
1007 SC1100 processors and the CS5535 and CS5536 Geode companion devices.
1009 If you don't know what to do here, say N.
1011 This support is also available as a module. If so, the module
1012 will be called scx200_acb.
