807 An adapter type parameter is now mandatory. Please read the file
808 Documentation/i2c/busses/i2c-parport for details.
810 Another driver exists, named i2c-parport-light, which doesn't depend
811 on the parport driver. This is meant for embedded systems. Don't say
812 Y here if you intend to say Y or M there.
814 This support is also available as a module. If so, the module
815 will be called i2c-parport.
817 config I2C_PARPORT_LIGHT
818 tristate "Parallel port adapter (light)"
819 depends on GENERIC_HARDIRQS
823 This supports parallel port I2C adapters such as the ones made by
824 Philips or Velleman, Analog Devices evaluation boards, and more.
825 Basically any adapter using the parallel port as an I2C bus with
826 no extra chipset is supported by this driver, or could be.
828 This driver is a light version of i2c-parport. It doesn't depend
829 on the parport driver, and uses direct I/O access instead. This
830 might be preferred on embedded systems where wasting memory for
831 the clean but heavy parport handling is not an option. The
832 drawback is a reduced portability and the impossibility to
833 daisy-chain other parallel port devices.
835 Don't say Y here if you said Y or M to i2c-parport. Saying M to
836 both is possible but both modules should not be loaded at the same
839 This support is also available as a module. If so, the module
840 will be called i2c-parport-light.
843 tristate "TAOS evaluation module"
849 This supports TAOS evaluation modules on serial port. In order to
850 use this driver, you will need the inputattach tool, which is part
851 of the input-utils package.
855 This support is also available as a module. If so, the module
856 will be called i2c-taos-evm.
859 tristate "Tiny-USB adapter"
862 If you say yes to this option, support will be included for the
863 i2c-tiny-usb, a simple do-it-yourself USB to I2C interface. See
864 http://www.harbaum.org/till/i2c_tiny_usb for hardware details.
866 This driver can also be built as a module. If so, the module
867 will be called i2c-tiny-usb.
869 config I2C_VIPERBOARD
870 tristate "Viperboard I2C master support"
871 depends on MFD_VIPERBOARD && USB
873 Say yes here to access the I2C part of the Nano River
874 Technologies Viperboard as I2C master.
875 See viperboard API specification and Nano
876 River Tech's viperboard.h for detailed meaning
877 of the module parameters.
879 comment "Other I2C/SMBus bus drivers"
882 tristate "Acorn IOC/IOMD I2C bus support"
883 depends on ARCH_ACORN
887 Say yes if you want to support the I2C bus on Acorn platforms.
889 If you don't know, say Y.
892 tristate "Elektor ISA card"
893 depends on ISA && HAS_IOPORT && BROKEN_ON_SMP
896 This supports the PCF8584 ISA bus I2C adapter. Say Y if you own
899 This support is also available as a module. If so, the module
900 will be called i2c-elektor.
903 tristate "PCA9564/PCA9665 on an ISA bus"
908 This driver supports ISA boards using the Philips PCA9564/PCA9665
909 parallel bus to I2C bus controller.
911 This driver can also be built as a module. If so, the module
912 will be called i2c-pca-isa.
914 This device is almost undetectable and using this driver on a
915 system which doesn't have this device will result in long
916 delays when I2C/SMBus chip drivers are loaded (e.g. at boot
917 time). If unsure, say N.
920 tristate "SiByte SMBus interface"
921 depends on SIBYTE_SB1xxx_SOC
923 Supports the SiByte SOC on-chip I2C interfaces (2 channels).
926 tristate "NatSemi SCx200 I2C using GPIO pins (DEPRECATED)"
927 depends on SCx200_GPIO
930 Enable the use of two GPIO pins of a SCx200 processor as an I2C bus.
932 If you don't know what to do here, say N.
934 This support is also available as a module. If so, the module
935 will be called scx200_i2c.
937 This driver is deprecated and will be dropped soon. Use i2c-gpio
938 (or scx200_acb) instead.
940 config SCx200_I2C_SCL
941 int "GPIO pin used for SCL"
942 depends on SCx200_I2C
945 Enter the GPIO pin number used for the SCL signal. This value can
946 also be specified with a module parameter.
948 config SCx200_I2C_SDA
949 int "GPIO pin used for SDA"
950 depends on SCx200_I2C
953 Enter the GPIO pin number used for the SSA signal. This value can
954 also be specified with a module parameter.
957 tristate "Geode ACCESS.bus support"
958 depends on X86_32 && PCI
960 Enable the use of the ACCESS.bus controllers on the Geode SCx200 and
961 SC1100 processors and the CS5535 and CS5536 Geode companion devices.
963 If you don't know what to do here, say N.
965 This support is also available as a module. If so, the module
966 will be called scx200_acb.
