| 12 | If you say yes to this option, support will be included for an |
| 13 | I2C multimaster arbitration scheme using GPIOs and a challenge & |
| 14 | response mechanism where masters have to claim the bus by asserting |
| 15 | a GPIO. |
| 16 | |
| 17 | This driver can also be built as a module. If so, the module |
| 18 | will be called i2c-arb-gpio-challenge. |

| 24 | If you say yes to this option, support will be included for a |

| 26 | I2C busses connected through a MUX, which is controlled |
| 27 | through GPIO pins. |

| 54 | help |
| 55 | If you say yes to this option, support will be included for an I2C |
| 56 | multiplexer that uses the pinctrl subsystem, i.e. pin multiplexing. |
| 57 | This is useful for SoCs whose I2C module's signals can be routed to |
| 58 | different sets of pins at run-time. |

| 60 | This driver can also be built as a module. If so, the module will be |
| 61 | called pinctrl-i2cmux. |
