+config I2C_AT91
+ tristate "Atmel AT91 I2C Two-Wire interface (TWI)"
+ 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.

+config I2C_AU1550
+ tristate "Au1550/Au1200 SMBus interface"
+ depends on SOC_AU1550 || SOC_AU1200
+ help
+ If you say yes to this option, support will be included for the
+ Au1550 and Au1200 SMBus interface.
+
+ This driver can also be built as a module. If so, the module
+ will be called i2c-au1550.
+
+config I2C_BLACKFIN_TWI
+ tristate "Blackfin TWI I2C support"
+ depends on BLACKFIN
+ depends on !BF561 && !BF531 && !BF532 && !BF533
+ help
+ This is the I2C bus driver for Blackfin on-chip TWI interface.
+
+ This driver can also be built as a module. If so, the module
+ will be called i2c-bfin-twi.
+
+config I2C_BLACKFIN_TWI_CLK_KHZ
+ int "Blackfin TWI I2C clock (kHz)"
+ depends on I2C_BLACKFIN_TWI
+ range 10 400
+ default 50
+ help
+ The unit of the TWI clock is kHz.
+
+config I2C_CPM
+ tristate "Freescale CPM1 or CPM2 (MPC8xx/826x)"
+ depends on (CPM1 || CPM2) && OF_I2C
+ help
+ This supports the use of the I2C interface on Freescale
+ processors with CPM1 or CPM2.
+
+ This driver can also be built as a module. If so, the module
+ will be called i2c-cpm.
+
+config I2C_DAVINCI
+ tristate "DaVinci I2C driver"
+ depends on ARCH_DAVINCI
+ help
+ Support for TI DaVinci I2C controller driver.
+
+ This driver can also be built as a module. If so, the module
+ will be called i2c-davinci.
+
+ Please note that this driver might be needed to bring up other
+ devices such as DaVinci NIC.
+ For details please see http://www.ti.com/davinci
+
+config I2C_GPIO
+ tristate "GPIO-based bitbanging I2C"
+ depends on GENERIC_GPIO
+ select I2C_ALGOBIT
+ help
+ This is a very simple bitbanging I2C driver utilizing the
+ arch-neutral GPIO API to control the SCL and SDA lines.
+
+config I2C_HIGHLANDER
+ tristate "Highlander FPGA SMBus interface"
+ depends on SH_HIGHLANDER
+ help
+ If you say yes to this option, support will be included for
+ the SMBus interface located in the FPGA on various Highlander
+ boards, particularly the R0P7780LC0011RL and R0P7785LC0011RL
+ FPGAs. This is wholly unrelated to the SoC I2C.
+
+ This driver can also be built as a module. If so, the module
+ will be called i2c-highlander.
+
+config I2C_IBM_IIC
+ tristate "IBM PPC 4xx on-chip I2C interface"
+ depends on 4xx
+ help
+ Say Y here if you want to use IIC peripheral found on
+ embedded IBM PPC 4xx based systems.
+
+ This driver can also be built as a module. If so, the module
+ will be called i2c-ibm_iic.
+
+config I2C_IMX
+ tristate "IMX I2C interface"
+ depends on ARCH_MXC
+ help
+ Say Y here if you want to use the IIC bus controller on
+ the Freescale i.MX/MXC processors.
+
+ This driver can also be built as a module. If so, the module
+ will be called i2c-imx.
+
+config I2C_IOP3XX
+ tristate "Intel IOPx3xx and IXP4xx on-chip I2C interface"
+ depends on ARCH_IOP32X || ARCH_IOP33X || ARCH_IXP4XX || ARCH_IOP13XX
+ help
+ Say Y here if you want to use the IIC bus controller on
+ the Intel IOPx3xx I/O Processors or IXP4xx Network Processors.
+
+ This driver can also be built as a module. If so, the module
+ will be called i2c-iop3xx.
+
+config I2C_IXP2000
+ tristate "IXP2000 GPIO-Based I2C Interface (DEPRECATED)"

+ select I2C_ALGOBIT
+ help
+ Say Y here if you have an Intel IXP2000 (2400, 2800, 2850) based
+ system and are using GPIO lines for an I2C bus.
+
+ This support is also available as a module. If so, the module
+ will be called i2c-ixp2000.
+
+ This driver is deprecated and will be dropped soon. Use i2c-gpio
+ instead.
