289 This supports the use of the I2C interface on Atmel AT91
292 This driver is BROKEN because the controller which it uses
293 will easily trigger RX overrun and TX underrun errors. Using
294 low I2C clock rates may partially work around those issues
295 on some systems. Another serious problem is that there is no
296 documented way to issue repeated START conditions, as needed
297 to support combined I2C messages. Use the i2c-gpio driver
298 unless your system can cope with those limitations.

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

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

805 will be called i2c-pca-isa.
807 This device is almost undetectable and using this driver on a

809 delays when I2C/SMBus chip drivers are loaded (e.g. at boot
810 time). If unsure, say N.
813 tristate "SiByte SMBus interface"
814 depends on SIBYTE_SB1xxx_SOC
816 Supports the SiByte SOC on-chip I2C interfaces (2 channels).
819 tristate "I2C/SMBus Test Stub"
820 depends on EXPERIMENTAL && m
823 This module may be useful to developers of SMBus client drivers,
824 especially for certain kinds of sensor chips.
826 If you do build this module, be sure to read the notes and warnings
827 in <file:Documentation/i2c/i2c-stub>.
829 If you don't know what to do here, definitely say N.
832 tristate "NatSemi SCx200 I2C using GPIO pins (DEPRECATED)"
833 depends on SCx200_GPIO
836 Enable the use of two GPIO pins of a SCx200 processor as an I2C bus.
838 If you don't know what to do here, say N.
840 This support is also available as a module. If so, the module
841 will be called scx200_i2c.
843 This driver is deprecated and will be dropped soon. Use i2c-gpio
844 (or scx200_acb) instead.
846 config SCx200_I2C_SCL
847 int "GPIO pin used for SCL"
848 depends on SCx200_I2C
851 Enter the GPIO pin number used for the SCL signal. This value can
852 also be specified with a module parameter.
854 config SCx200_I2C_SDA
855 int "GPIO pin used for SDA"
856 depends on SCx200_I2C
859 Enter the GPIO pin number used for the SSA signal. This value can
860 also be specified with a module parameter.
863 tristate "Geode ACCESS.bus support"
864 depends on X86_32 && PCI
866 Enable the use of the ACCESS.bus controllers on the Geode SCx200 and
867 SC1100 processors and the CS5535 and CS5536 Geode companion devices.
869 If you don't know what to do here, say N.
871 This support is also available as a module. If so, the module
872 will be called scx200_acb.
