298 will easily trigger RX overrun and TX underrun errors. Using
299 low I2C clock rates may partially work around those issues
300 on some systems. Another serious problem is that there is no
301 documented way to issue repeated START conditions, as needed
302 to support combined I2C messages. Use the i2c-gpio driver

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

772 Basically any adapter using the parallel port as an I2C bus with

775 This driver is a light version of i2c-parport. It doesn't depend
776 on the parport driver, and uses direct I/O access instead. This
777 might be preferred on embedded systems where wasting memory for
778 the clean but heavy parport handling is not an option. The
779 drawback is a reduced portability and the impossibility to
780 daisy-chain other parallel port devices.
782 Don't say Y here if you said Y or M to i2c-parport. Saying M to
783 both is possible but both modules should not be loaded at the same

797 use this driver, you will need the inputattach tool, which is part
798 of the input-utils package.
802 This support is also available as a module. If so, the module
803 will be called i2c-taos-evm.
806 tristate "Tiny-USB adapter"
809 If you say yes to this option, support will be included for the
810 i2c-tiny-usb, a simple do-it-yourself USB to I2C interface. See
811 http://www.harbaum.org/till/i2c_tiny_usb for hardware details.
813 This driver can also be built as a module. If so, the module
814 will be called i2c-tiny-usb.
816 comment "Other I2C/SMBus bus drivers"
819 tristate "Acorn IOC/IOMD I2C bus support"
820 depends on ARCH_ACORN
824 Say yes if you want to support the I2C bus on Acorn platforms.
826 If you don't know, say Y.
829 tristate "Elektor ISA card"
830 depends on ISA && HAS_IOPORT && BROKEN_ON_SMP
833 This supports the PCF8584 ISA bus I2C adapter. Say Y if you own
836 This support is also available as a module. If so, the module
837 will be called i2c-elektor.
840 tristate "PCA9564/PCA9665 on an ISA bus"
845 This driver supports ISA boards using the Philips PCA9564/PCA9665
846 parallel bus to I2C bus controller.
848 This driver can also be built as a module. If so, the module
849 will be called i2c-pca-isa.
851 This device is almost undetectable and using this driver on a
852 system which doesn't have this device will result in long
853 delays when I2C/SMBus chip drivers are loaded (e.g. at boot
854 time). If unsure, say N.
857 tristate "SiByte SMBus interface"
858 depends on SIBYTE_SB1xxx_SOC
860 Supports the SiByte SOC on-chip I2C interfaces (2 channels).
863 tristate "I2C/SMBus Test Stub"
864 depends on EXPERIMENTAL && m
867 This module may be useful to developers of SMBus client drivers,
868 especially for certain kinds of sensor chips.
870 If you do build this module, be sure to read the notes and warnings
871 in <file:Documentation/i2c/i2c-stub>.
873 If you don't know what to do here, definitely say N.
876 tristate "NatSemi SCx200 I2C using GPIO pins (DEPRECATED)"
877 depends on SCx200_GPIO
880 Enable the use of two GPIO pins of a SCx200 processor as an I2C bus.
882 If you don't know what to do here, say N.
884 This support is also available as a module. If so, the module
885 will be called scx200_i2c.
887 This driver is deprecated and will be dropped soon. Use i2c-gpio
888 (or scx200_acb) instead.
890 config SCx200_I2C_SCL
891 int "GPIO pin used for SCL"
892 depends on SCx200_I2C
895 Enter the GPIO pin number used for the SCL signal. This value can
896 also be specified with a module parameter.
898 config SCx200_I2C_SDA
899 int "GPIO pin used for SDA"
900 depends on SCx200_I2C
903 Enter the GPIO pin number used for the SSA signal. This value can
904 also be specified with a module parameter.
907 tristate "Geode ACCESS.bus support"
908 depends on X86_32 && PCI
910 Enable the use of the ACCESS.bus controllers on the Geode SCx200 and
911 SC1100 processors and the CS5535 and CS5536 Geode companion devices.
913 If you don't know what to do here, say N.
915 This support is also available as a module. If so, the module
916 will be called scx200_acb.
