756 tristate "Parallel port adapter"
761 This supports parallel port I2C adapters such as the ones made by
762 Philips or Velleman, Analog Devices evaluation boards, and more.
763 Basically any adapter using the parallel port as an I2C bus with
764 no extra chipset is supported by this driver, or could be.
766 This driver is a replacement for (and was inspired by) an older
767 driver named i2c-philips-par. The new driver supports more devices,
768 and makes it easier to add support for new devices.
770 An adapter type parameter is now mandatory. Please read the file
771 Documentation/i2c/busses/i2c-parport for details.
773 Another driver exists, named i2c-parport-light, which doesn't depend
774 on the parport driver. This is meant for embedded systems. Don't say
775 Y here if you intend to say Y or M there.

787 Basically any adapter using the parallel port as an I2C bus with
788 no extra chipset is supported by this driver, or could be.
790 This driver is a light version of i2c-parport. It doesn't depend
791 on the parport driver, and uses direct I/O access instead. This
792 might be preferred on embedded systems where wasting memory for
793 the clean but heavy parport handling is not an option. The
794 drawback is a reduced portability and the impossibility to
795 daisy-chain other parallel port devices.
797 Don't say Y here if you said Y or M to i2c-parport. Saying M to
798 both is possible but both modules should not be loaded at the same
801 This support is also available as a module. If so, the module
802 will be called i2c-parport-light.
805 tristate "TAOS evaluation module"
806 depends on EXPERIMENTAL
811 This supports TAOS evaluation modules on serial port. In order to
812 use this driver, you will need the inputattach tool, which is part
813 of the input-utils package.
817 This support is also available as a module. If so, the module
818 will be called i2c-taos-evm.
821 tristate "Tiny-USB adapter"
824 If you say yes to this option, support will be included for the
825 i2c-tiny-usb, a simple do-it-yourself USB to I2C interface. See
826 http://www.harbaum.org/till/i2c_tiny_usb for hardware details.
828 This driver can also be built as a module. If so, the module
829 will be called i2c-tiny-usb.
831 config I2C_VIPERBOARD
832 tristate "Viperboard I2C master support"
833 depends on MFD_VIPERBOARD && USB
835 Say yes here to access the I2C part of the Nano River
836 Technologies Viperboard as I2C master.
837 See viperboard API specification and Nano
838 River Tech's viperboard.h for detailed meaning
839 of the module parameters.
841 comment "Other I2C/SMBus bus drivers"
844 tristate "Acorn IOC/IOMD I2C bus support"
845 depends on ARCH_ACORN
849 Say yes if you want to support the I2C bus on Acorn platforms.
851 If you don't know, say Y.
854 tristate "Elektor ISA card"
855 depends on ISA && HAS_IOPORT && BROKEN_ON_SMP
858 This supports the PCF8584 ISA bus I2C adapter. Say Y if you own
861 This support is also available as a module. If so, the module
862 will be called i2c-elektor.
865 tristate "PCA9564/PCA9665 on an ISA bus"
870 This driver supports ISA boards using the Philips PCA9564/PCA9665
871 parallel bus to I2C bus controller.
873 This driver can also be built as a module. If so, the module
874 will be called i2c-pca-isa.
876 This device is almost undetectable and using this driver on a
877 system which doesn't have this device will result in long
878 delays when I2C/SMBus chip drivers are loaded (e.g. at boot
879 time). If unsure, say N.
882 tristate "SiByte SMBus interface"
883 depends on SIBYTE_SB1xxx_SOC
885 Supports the SiByte SOC on-chip I2C interfaces (2 channels).
888 tristate "NatSemi SCx200 I2C using GPIO pins (DEPRECATED)"
889 depends on SCx200_GPIO
892 Enable the use of two GPIO pins of a SCx200 processor as an I2C bus.
894 If you don't know what to do here, say N.
896 This support is also available as a module. If so, the module
897 will be called scx200_i2c.
899 This driver is deprecated and will be dropped soon. Use i2c-gpio
900 (or scx200_acb) instead.
902 config SCx200_I2C_SCL
903 int "GPIO pin used for SCL"
904 depends on SCx200_I2C
907 Enter the GPIO pin number used for the SCL signal. This value can
908 also be specified with a module parameter.
910 config SCx200_I2C_SDA
911 int "GPIO pin used for SDA"
912 depends on SCx200_I2C
915 Enter the GPIO pin number used for the SSA signal. This value can
916 also be specified with a module parameter.
919 tristate "Geode ACCESS.bus support"
920 depends on X86_32 && PCI
922 Enable the use of the ACCESS.bus controllers on the Geode SCx200 and
923 SC1100 processors and the CS5535 and CS5536 Geode companion devices.
925 If you don't know what to do here, say N.
927 This support is also available as a module. If so, the module
928 will be called scx200_acb.
