| config I2C_ARB_GPIO_CHALLENGE |
| tristate "GPIO-based I2C arbitration" |
| depends on GENERIC_GPIO && 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 GENERIC_GPIO |
| 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_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 "Philips PCA954x I2C Mux/switches" |
| help |
| If you say yes here you get support for the Philips PCA954x |
| 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 |
| 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 pinctrl-i2cmux. |
