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

720 tristate "Parallel port adapter"
725 This supports parallel port I2C adapters such as the ones made by
726 Philips or Velleman, Analog Devices evaluation boards, and more.
727 Basically any adapter using the parallel port as an I2C bus with
728 no extra chipset is supported by this driver, or could be.
730 This driver is a replacement for (and was inspired by) an older
731 driver named i2c-philips-par. The new driver supports more devices,
732 and makes it easier to add support for new devices.
734 An adapter type parameter is now mandatory. Please read the file
735 Documentation/i2c/busses/i2c-parport for details.
737 Another driver exists, named i2c-parport-light, which doesn't depend
738 on the parport driver. This is meant for embedded systems. Don't say

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

798 tristate "Acorn IOC/IOMD I2C bus support"
799 depends on ARCH_ACORN
803 Say yes if you want to support the I2C bus on Acorn platforms.
805 If you don't know, say Y.
808 tristate "Elektor ISA card"
809 depends on ISA && HAS_IOPORT && BROKEN_ON_SMP
812 This supports the PCF8584 ISA bus I2C adapter. Say Y if you own
815 This support is also available as a module. If so, the module
816 will be called i2c-elektor.
819 tristate "PCA9564/PCA9665 on an ISA bus"
824 This driver supports ISA boards using the Philips PCA9564/PCA9665
825 parallel bus to I2C bus controller.
827 This driver can also be built as a module. If so, the module
828 will be called i2c-pca-isa.
830 This device is almost undetectable and using this driver on a
831 system which doesn't have this device will result in long
832 delays when I2C/SMBus chip drivers are loaded (e.g. at boot
833 time). If unsure, say N.
836 tristate "SiByte SMBus interface"
837 depends on SIBYTE_SB1xxx_SOC
839 Supports the SiByte SOC on-chip I2C interfaces (2 channels).
842 tristate "I2C/SMBus Test Stub"
843 depends on EXPERIMENTAL && m
846 This module may be useful to developers of SMBus client drivers,
847 especially for certain kinds of sensor chips.
849 If you do build this module, be sure to read the notes and warnings
850 in <file:Documentation/i2c/i2c-stub>.
852 If you don't know what to do here, definitely say N.
855 tristate "NatSemi SCx200 I2C using GPIO pins (DEPRECATED)"
856 depends on SCx200_GPIO
859 Enable the use of two GPIO pins of a SCx200 processor as an I2C bus.
861 If you don't know what to do here, say N.
863 This support is also available as a module. If so, the module
864 will be called scx200_i2c.
866 This driver is deprecated and will be dropped soon. Use i2c-gpio
867 (or scx200_acb) instead.
869 config SCx200_I2C_SCL
870 int "GPIO pin used for SCL"
871 depends on SCx200_I2C
874 Enter the GPIO pin number used for the SCL signal. This value can
875 also be specified with a module parameter.
877 config SCx200_I2C_SDA
878 int "GPIO pin used for SDA"
879 depends on SCx200_I2C
882 Enter the GPIO pin number used for the SSA signal. This value can
883 also be specified with a module parameter.
886 tristate "Geode ACCESS.bus support"
887 depends on X86_32 && PCI
889 Enable the use of the ACCESS.bus controllers on the Geode SCx200 and
890 SC1100 processors and the CS5535 and CS5536 Geode companion devices.
892 If you don't know what to do here, say N.
894 This support is also available as a module. If so, the module
895 will be called scx200_acb.
