+config I2C_ARB_GPIO_CHALLENGE
+ tristate "GPIO-based I2C arbitration"
+ depends on GPIOLIB || COMPILE_TEST
+ depends on OF
+ help
+ If you say yes to this option, support will be included for an
+ I2C multimaster arbitration scheme using GPIOs and a challenge &
+ response mechanism where masters have to claim the bus by asserting
+ a GPIO.
+
+ This driver can also be built as a module. If so, the module
+ will be called i2c-arb-gpio-challenge.
+
+config I2C_MUX_GPIO
+ tristate "GPIO-based I2C multiplexer"
+ depends on GPIOLIB
+ help
+ If you say yes to this option, support will be included for a
+ GPIO based I2C multiplexer. This driver provides access to
+ I2C busses connected through a MUX, which is controlled
+ through GPIO pins.
+
+ This driver can also be built as a module. If so, the module
+ will be called i2c-mux-gpio.
+
+config I2C_MUX_GPMUX
+ tristate "General Purpose I2C multiplexer"
+ select MULTIPLEXER
+ depends on OF
+ help
+ If you say yes to this option, support will be included for a
+ general purpose I2C multiplexer. This driver provides access to
+ I2C busses connected through a MUX, which in turn is controlled
+ by a MUX-controller from the MUX subsystem.
+
+ This driver can also be built as a module. If so, the module
+ will be called i2c-mux-gpmux.
+
+config I2C_MUX_LTC4306
+ tristate "LTC LTC4306/5 I2C multiplexer"
+ select GPIOLIB
+ select REGMAP_I2C
+ help
+ If you say yes here you get support for the Analog Devices
+ LTC4306 or LTC4305 I2C mux/switch devices.
+
+ This driver can also be built as a module. If so, the module
+ will be called i2c-mux-ltc4306.
+
+config I2C_MUX_PCA9541
+ tristate "NXP PCA9541 I2C Master Selector"
+ help
+ If you say yes here you get support for the NXP PCA9541
+ I2C Master Selector.
+
+ This driver can also be built as a module. If so, the module
+ will be called i2c-mux-pca9541.
+
+config I2C_MUX_PCA954x
+ tristate "NXP PCA954x and PCA984x I2C Mux/switches"
+ depends on GPIOLIB || COMPILE_TEST
+ help
+ If you say yes here you get support for the NXP PCA954x
+ and PCA984x I2C mux/switch devices.
+
+ This driver can also be built as a module. If so, the module
+ will be called i2c-mux-pca954x.
+
+config I2C_MUX_PINCTRL
+ tristate "pinctrl-based I2C multiplexer"
+ depends on PINCTRL
+ depends on OF
+ help
+ If you say yes to this option, support will be included for an I2C
+ multiplexer that uses the pinctrl subsystem, i.e. pin multiplexing.
+ This is useful for SoCs whose I2C module's signals can be routed to
+ different sets of pins at run-time.
+
+ This driver can also be built as a module. If so, the module will be
+ called i2c-mux-pinctrl.
+
+config I2C_MUX_REG
+ tristate "Register-based I2C multiplexer"
+ depends on HAS_IOMEM
+ help
+ If you say yes to this option, support will be included for a
+ register based I2C multiplexer. This driver provides access to
+ I2C busses connected through a MUX, which is controlled
+ by a single register.
+
+ This driver can also be built as a module. If so, the module
+ will be called i2c-mux-reg.
+
+config I2C_DEMUX_PINCTRL
+ tristate "pinctrl-based I2C demultiplexer"
+ depends on PINCTRL && OF
+ select OF_DYNAMIC
+ help
+ If you say yes to this option, support will be included for an I2C
+ demultiplexer that uses the pinctrl subsystem. This is useful if you
+ want to change the I2C master at run-time depending on features.
+
+config I2C_MUX_MLXCPLD
+ tristate "Mellanox CPLD based I2C multiplexer"
+ help
+ If you say yes to this option, support will be included for a
+ CPLD based I2C multiplexer. This driver provides access to
+ I2C busses connected through a MUX, which is controlled
+ by a CPLD register.
+
+ This driver can also be built as a module. If so, the module
+ will be called i2c-mux-mlxcpld.
