820 the Netlogic XLR/XLS MIPS processors.
822 This driver can also be built as a module. If so, the module
823 will be called i2c-xlr.
826 tristate "Renesas R-Car I2C Controller"
827 depends on ARCH_SHMOBILE || COMPILE_TEST
829 If you say yes to this option, support will be included for the
830 R-Car I2C controller.
832 This driver can also be built as a module. If so, the module
833 will be called i2c-rcar.
835 comment "External I2C/SMBus adapter drivers"
837 config I2C_DIOLAN_U2C
838 tristate "Diolan U2C-12 USB adapter"
841 If you say yes to this option, support will be included for Diolan
842 U2C-12, a USB to I2C interface.
844 This driver can also be built as a module. If so, the module
845 will be called i2c-diolan-u2c.
848 tristate "Parallel port adapter"
853 This supports parallel port I2C adapters such as the ones made by
854 Philips or Velleman, Analog Devices evaluation boards, and more.
855 Basically any adapter using the parallel port as an I2C bus with
856 no extra chipset is supported by this driver, or could be.
858 This driver is a replacement for (and was inspired by) an older
859 driver named i2c-philips-par. The new driver supports more devices,
860 and makes it easier to add support for new devices.
862 An adapter type parameter is now mandatory. Please read the file
863 Documentation/i2c/busses/i2c-parport for details.
865 Another driver exists, named i2c-parport-light, which doesn't depend
866 on the parport driver. This is meant for embedded systems. Don't say
867 Y here if you intend to say Y or M there.
869 This support is also available as a module. If so, the module
870 will be called i2c-parport.
872 config I2C_PARPORT_LIGHT
873 tristate "Parallel port adapter (light)"
877 This supports parallel port I2C adapters such as the ones made by
878 Philips or Velleman, Analog Devices evaluation boards, and more.
879 Basically any adapter using the parallel port as an I2C bus with
880 no extra chipset is supported by this driver, or could be.
882 This driver is a light version of i2c-parport. It doesn't depend
883 on the parport driver, and uses direct I/O access instead. This
884 might be preferred on embedded systems where wasting memory for
885 the clean but heavy parport handling is not an option. The
886 drawback is a reduced portability and the impossibility to
887 daisy-chain other parallel port devices.
889 Don't say Y here if you said Y or M to i2c-parport. Saying M to
890 both is possible but both modules should not be loaded at the same
893 This support is also available as a module. If so, the module
894 will be called i2c-parport-light.
896 config I2C_ROBOTFUZZ_OSIF
897 tristate "RobotFuzz Open Source InterFace USB adapter"
900 If you say yes to this option, support will be included for the
901 RobotFuzz Open Source InterFace USB to I2C interface.
903 This driver can also be built as a module. If so, the module
904 will be called i2c-osif.
907 tristate "TAOS evaluation module"
913 This supports TAOS evaluation modules on serial port. In order to
914 use this driver, you will need the inputattach tool, which is part
915 of the input-utils package.
919 This support is also available as a module. If so, the module
920 will be called i2c-taos-evm.
923 tristate "Tiny-USB adapter"
926 If you say yes to this option, support will be included for the
927 i2c-tiny-usb, a simple do-it-yourself USB to I2C interface. See
928 http://www.harbaum.org/till/i2c_tiny_usb for hardware details.
930 This driver can also be built as a module. If so, the module
931 will be called i2c-tiny-usb.
933 config I2C_VIPERBOARD
934 tristate "Viperboard I2C master support"
935 depends on MFD_VIPERBOARD && USB
937 Say yes here to access the I2C part of the Nano River
938 Technologies Viperboard as I2C master.
939 See viperboard API specification and Nano
940 River Tech's viperboard.h for detailed meaning
941 of the module parameters.
943 comment "Other I2C/SMBus bus drivers"
946 tristate "Acorn IOC/IOMD I2C bus support"
947 depends on ARCH_ACORN
951 Say yes if you want to support the I2C bus on Acorn platforms.
953 If you don't know, say Y.
956 tristate "Elektor ISA card"
957 depends on ISA && HAS_IOPORT && BROKEN_ON_SMP
960 This supports the PCF8584 ISA bus I2C adapter. Say Y if you own
963 This support is also available as a module. If so, the module
964 will be called i2c-elektor.
967 tristate "PCA9564/PCA9665 on an ISA bus"
972 This driver supports ISA boards using the Philips PCA9564/PCA9665
973 parallel bus to I2C bus controller.
975 This driver can also be built as a module. If so, the module
976 will be called i2c-pca-isa.
978 This device is almost undetectable and using this driver on a
979 system which doesn't have this device will result in long
980 delays when I2C/SMBus chip drivers are loaded (e.g. at boot
981 time). If unsure, say N.
984 tristate "SiByte SMBus interface"
985 depends on SIBYTE_SB1xxx_SOC
987 Supports the SiByte SOC on-chip I2C interfaces (2 channels).
990 tristate "NatSemi SCx200 I2C using GPIO pins (DEPRECATED)"
991 depends on SCx200_GPIO
994 Enable the use of two GPIO pins of a SCx200 processor as an I2C bus.
996 If you don't know what to do here, say N.
998 This support is also available as a module. If so, the module
999 will be called scx200_i2c.
1001 This driver is deprecated and will be dropped soon. Use i2c-gpio
1002 (or scx200_acb) instead.
1004 config SCx200_I2C_SCL
1005 int "GPIO pin used for SCL"
1006 depends on SCx200_I2C
1009 Enter the GPIO pin number used for the SCL signal. This value can
1010 also be specified with a module parameter.
1012 config SCx200_I2C_SDA
1013 int "GPIO pin used for SDA"
1014 depends on SCx200_I2C
1017 Enter the GPIO pin number used for the SSA signal. This value can
1018 also be specified with a module parameter.
1021 tristate "Geode ACCESS.bus support"
1022 depends on X86_32 && PCI
1024 Enable the use of the ACCESS.bus controllers on the Geode SCx200 and
1025 SC1100 processors and the CS5535 and CS5536 Geode companion devices.
1027 If you don't know what to do here, say N.
1029 This support is also available as a module. If so, the module
1030 will be called scx200_acb.
