	depends on ARCH_AT91 && EXPERIMENTAL && BROKEN
	help
	  This supports the use of the I2C interface on Atmel AT91
	  processors.

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

	  Basically any adapter using the parallel port as an I2C bus with

	  This driver is a replacement for (and was inspired by) an older

	  An adapter type parameter is now mandatory.  Please read the file

	  might be preferred on embedded systems where wasting memory for
	  the clean but heavy parport handling is not an option.  The
	  drawback is a reduced portability and the impossibility to
	  daisy-chain other parallel port devices.

	  Don't say Y here if you said Y or M to i2c-parport.  Saying M to

	help
	  If you say yes to this option, support will be included for the
	  Voodoo 3 I2C interface. This driver is deprecated and you should
	  use the tdfxfb driver instead, which additionally provides
	  framebuffer support.

	  This driver can also be built as a module.  If so, the module
	  will be called i2c-voodoo3.

comment "Other I2C/SMBus bus drivers"

config I2C_ACORN
	tristate "Acorn IOC/IOMD I2C bus support"
	depends on ARCH_ACORN
	default y
	select I2C_ALGOBIT
	help
	  Say yes if you want to support the I2C bus on Acorn platforms.

	  If you don't know, say Y.

config I2C_ELEKTOR
	tristate "Elektor ISA card"
	depends on ISA && BROKEN_ON_SMP
	select I2C_ALGOPCF
	help
	  This supports the PCF8584 ISA bus I2C adapter.  Say Y if you own
	  such an adapter.

	  This support is also available as a module.  If so, the module
	  will be called i2c-elektor.

config I2C_PCA_ISA
	tristate "PCA9564/PCA9665 on an ISA bus"
	depends on ISA
	select I2C_ALGOPCA
	default n
	help
	  This driver supports ISA boards using the Philips PCA9564/PCA9665
	  parallel bus to I2C bus controller.

	  This driver can also be built as a module.  If so, the module
	  will be called i2c-pca-isa.

	  This device is almost undetectable and using this driver on a
	  system which doesn't have this device will result in long
	  delays when I2C/SMBus chip drivers are loaded (e.g. at boot
	  time).  If unsure, say N.

config I2C_PCA_PLATFORM
	tristate "PCA9564/PCA9665 as platform device"
	select I2C_ALGOPCA
	default n
	help
	  This driver supports a memory mapped Philips PCA9564/PCA9665
	  parallel bus to I2C bus controller.

	  This driver can also be built as a module.  If so, the module
	  will be called i2c-pca-platform.

config I2C_PMCMSP
	tristate "PMC MSP I2C TWI Controller"
	depends on PMC_MSP
	help
	  This driver supports the PMC TWI controller on MSP devices.

	  This driver can also be built as module. If so, the module
	  will be called i2c-pmcmsp.

config I2C_SIBYTE
	tristate "SiByte SMBus interface"
	depends on SIBYTE_SB1xxx_SOC
	help
	  Supports the SiByte SOC on-chip I2C interfaces (2 channels).

config I2C_STUB
	tristate "I2C/SMBus Test Stub"
	depends on EXPERIMENTAL && m
	default 'n'
	help
	  This module may be useful to developers of SMBus client drivers,
	  especially for certain kinds of sensor chips.

	  If you do build this module, be sure to read the notes and warnings
	  in <file:Documentation/i2c/i2c-stub>.

	  If you don't know what to do here, definitely say N.

config SCx200_I2C
	tristate "NatSemi SCx200 I2C using GPIO pins (DEPRECATED)"
	depends on SCx200_GPIO
	select I2C_ALGOBIT
	help
	  Enable the use of two GPIO pins of a SCx200 processor as an I2C bus.

	  If you don't know what to do here, say N.

	  This support is also available as a module.  If so, the module
	  will be called scx200_i2c.

	  This driver is deprecated and will be dropped soon. Use i2c-gpio
	  (or scx200_acb) instead.

config SCx200_I2C_SCL
	int "GPIO pin used for SCL"
	depends on SCx200_I2C
	default "12"
	help
	  Enter the GPIO pin number used for the SCL signal.  This value can
	  also be specified with a module parameter.

config SCx200_I2C_SDA
	int "GPIO pin used for SDA"
	depends on SCx200_I2C
	default "13"
	help
	  Enter the GPIO pin number used for the SSA signal.  This value can
	  also be specified with a module parameter.

config SCx200_ACB
	tristate "Geode ACCESS.bus support"
	depends on X86_32 && PCI
	help
	  Enable the use of the ACCESS.bus controllers on the Geode SCx200 and
	  SC1100 processors and the CS5535 and CS5536 Geode companion devices.

	  If you don't know what to do here, say N.

	  This support is also available as a module.  If so, the module
	  will be called scx200_acb.
