297 on some systems. Another serious problem is that there is no
298 documented way to issue repeated START conditions, as needed

703 tristate "Parallel port adapter"
708 This supports parallel port I2C adapters such as the ones made by
709 Philips or Velleman, Analog Devices evaluation boards, and more.
710 Basically any adapter using the parallel port as an I2C bus with
711 no extra chipset is supported by this driver, or could be.
713 This driver is a replacement for (and was inspired by) an older
714 driver named i2c-philips-par. The new driver supports more devices,
715 and makes it easier to add support for new devices.
717 An adapter type parameter is now mandatory. Please read the file
718 Documentation/i2c/busses/i2c-parport for details.
720 Another driver exists, named i2c-parport-light, which doesn't depend
721 on the parport driver. This is meant for embedded systems. Don't say
722 Y here if you intend to say Y or M there.

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

802 tristate "PCA9564/PCA9665 on an ISA bus"
807 This driver supports ISA boards using the Philips PCA9564/PCA9665
808 parallel bus to I2C bus controller.
810 This driver can also be built as a module. If so, the module
811 will be called i2c-pca-isa.
813 This device is almost undetectable and using this driver on a
814 system which doesn't have this device will result in long
815 delays when I2C/SMBus chip drivers are loaded (e.g. at boot
816 time). If unsure, say N.
819 tristate "SiByte SMBus interface"
820 depends on SIBYTE_SB1xxx_SOC
822 Supports the SiByte SOC on-chip I2C interfaces (2 channels).
825 tristate "I2C/SMBus Test Stub"
826 depends on EXPERIMENTAL && m
829 This module may be useful to developers of SMBus client drivers,
830 especially for certain kinds of sensor chips.
832 If you do build this module, be sure to read the notes and warnings
833 in <file:Documentation/i2c/i2c-stub>.
835 If you don't know what to do here, definitely say N.
838 tristate "NatSemi SCx200 I2C using GPIO pins (DEPRECATED)"
839 depends on SCx200_GPIO
842 Enable the use of two GPIO pins of a SCx200 processor as an I2C bus.
844 If you don't know what to do here, say N.
846 This support is also available as a module. If so, the module
847 will be called scx200_i2c.
849 This driver is deprecated and will be dropped soon. Use i2c-gpio
850 (or scx200_acb) instead.
852 config SCx200_I2C_SCL
853 int "GPIO pin used for SCL"
854 depends on SCx200_I2C
857 Enter the GPIO pin number used for the SCL signal. This value can
858 also be specified with a module parameter.
860 config SCx200_I2C_SDA
861 int "GPIO pin used for SDA"
862 depends on SCx200_I2C
865 Enter the GPIO pin number used for the SSA signal. This value can
866 also be specified with a module parameter.
869 tristate "Geode ACCESS.bus support"
870 depends on X86_32 && PCI
872 Enable the use of the ACCESS.bus controllers on the Geode SCx200 and
873 SC1100 processors and the CS5535 and CS5536 Geode companion devices.
875 If you don't know what to do here, say N.
877 This support is also available as a module. If so, the module
878 will be called scx200_acb.
