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

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

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

791 depends on ARCH_ACORN
795 Say yes if you want to support the I2C bus on Acorn platforms.
797 If you don't know, say Y.
800 tristate "Elektor ISA card"
801 depends on ISA && HAS_IOPORT && BROKEN_ON_SMP
804 This supports the PCF8584 ISA bus I2C adapter. Say Y if you own
807 This support is also available as a module. If so, the module
808 will be called i2c-elektor.
811 tristate "PCA9564/PCA9665 on an ISA bus"
816 This driver supports ISA boards using the Philips PCA9564/PCA9665
817 parallel bus to I2C bus controller.
819 This driver can also be built as a module. If so, the module
820 will be called i2c-pca-isa.
822 This device is almost undetectable and using this driver on a
823 system which doesn't have this device will result in long
824 delays when I2C/SMBus chip drivers are loaded (e.g. at boot
825 time). If unsure, say N.
828 tristate "SiByte SMBus interface"
829 depends on SIBYTE_SB1xxx_SOC
831 Supports the SiByte SOC on-chip I2C interfaces (2 channels).
834 tristate "I2C/SMBus Test Stub"
835 depends on EXPERIMENTAL && m
838 This module may be useful to developers of SMBus client drivers,
839 especially for certain kinds of sensor chips.
841 If you do build this module, be sure to read the notes and warnings
842 in <file:Documentation/i2c/i2c-stub>.
844 If you don't know what to do here, definitely say N.
847 tristate "NatSemi SCx200 I2C using GPIO pins (DEPRECATED)"
848 depends on SCx200_GPIO
851 Enable the use of two GPIO pins of a SCx200 processor as an I2C bus.
853 If you don't know what to do here, say N.
855 This support is also available as a module. If so, the module
856 will be called scx200_i2c.
858 This driver is deprecated and will be dropped soon. Use i2c-gpio
859 (or scx200_acb) instead.
861 config SCx200_I2C_SCL
862 int "GPIO pin used for SCL"
863 depends on SCx200_I2C
866 Enter the GPIO pin number used for the SCL signal. This value can
867 also be specified with a module parameter.
869 config SCx200_I2C_SDA
870 int "GPIO pin used for SDA"
871 depends on SCx200_I2C
874 Enter the GPIO pin number used for the SSA signal. This value can
875 also be specified with a module parameter.
878 tristate "Geode ACCESS.bus support"
879 depends on X86_32 && PCI
881 Enable the use of the ACCESS.bus controllers on the Geode SCx200 and
882 SC1100 processors and the CS5535 and CS5536 Geode companion devices.
884 If you don't know what to do here, say N.
886 This support is also available as a module. If so, the module
887 will be called scx200_acb.
