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

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

762 Basically any adapter using the parallel port as an I2C bus with
763 no extra chipset is supported by this driver, or could be.
765 This driver is a light version of i2c-parport. It doesn't depend
766 on the parport driver, and uses direct I/O access instead. This
767 might be preferred on embedded systems where wasting memory for
768 the clean but heavy parport handling is not an option. The
769 drawback is a reduced portability and the impossibility to
770 daisy-chain other parallel port devices.
772 Don't say Y here if you said Y or M to i2c-parport. Saying M to
773 both is possible but both modules should not be loaded at the same

799 If you say yes to this option, support will be included for the
800 i2c-tiny-usb, a simple do-it-yourself USB to I2C interface. See
801 http://www.harbaum.org/till/i2c_tiny_usb for hardware details.
803 This driver can also be built as a module. If so, the module
804 will be called i2c-tiny-usb.
806 comment "Other I2C/SMBus bus drivers"
809 tristate "Acorn IOC/IOMD I2C bus support"
810 depends on ARCH_ACORN
814 Say yes if you want to support the I2C bus on Acorn platforms.
816 If you don't know, say Y.
819 tristate "Elektor ISA card"
820 depends on ISA && HAS_IOPORT && BROKEN_ON_SMP
823 This supports the PCF8584 ISA bus I2C adapter. Say Y if you own
826 This support is also available as a module. If so, the module
827 will be called i2c-elektor.
830 tristate "PCA9564/PCA9665 on an ISA bus"
835 This driver supports ISA boards using the Philips PCA9564/PCA9665
836 parallel bus to I2C bus controller.
838 This driver can also be built as a module. If so, the module
839 will be called i2c-pca-isa.
841 This device is almost undetectable and using this driver on a
842 system which doesn't have this device will result in long
843 delays when I2C/SMBus chip drivers are loaded (e.g. at boot
844 time). If unsure, say N.
847 tristate "SiByte SMBus interface"
848 depends on SIBYTE_SB1xxx_SOC
850 Supports the SiByte SOC on-chip I2C interfaces (2 channels).
853 tristate "I2C/SMBus Test Stub"
854 depends on EXPERIMENTAL && m
857 This module may be useful to developers of SMBus client drivers,
858 especially for certain kinds of sensor chips.
860 If you do build this module, be sure to read the notes and warnings
861 in <file:Documentation/i2c/i2c-stub>.
863 If you don't know what to do here, definitely say N.
866 tristate "NatSemi SCx200 I2C using GPIO pins (DEPRECATED)"
867 depends on SCx200_GPIO
870 Enable the use of two GPIO pins of a SCx200 processor as an I2C bus.
872 If you don't know what to do here, say N.
874 This support is also available as a module. If so, the module
875 will be called scx200_i2c.
877 This driver is deprecated and will be dropped soon. Use i2c-gpio
878 (or scx200_acb) instead.
880 config SCx200_I2C_SCL
881 int "GPIO pin used for SCL"
882 depends on SCx200_I2C
885 Enter the GPIO pin number used for the SCL signal. This value can
886 also be specified with a module parameter.
888 config SCx200_I2C_SDA
889 int "GPIO pin used for SDA"
890 depends on SCx200_I2C
893 Enter the GPIO pin number used for the SSA signal. This value can
894 also be specified with a module parameter.
897 tristate "Geode ACCESS.bus support"
898 depends on X86_32 && PCI
900 Enable the use of the ACCESS.bus controllers on the Geode SCx200 and
901 SC1100 processors and the CS5535 and CS5536 Geode companion devices.
903 If you don't know what to do here, say N.
905 This support is also available as a module. If so, the module
906 will be called scx200_acb.
