11 | help |
| 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. | |

| 92ed1a76 PK |
23 | help |
| 24 | If you say yes to this option, support will be included for a | |
| 25 | GPIO based I2C multiplexer. This driver provides access to | |
| 26 | I2C busses connected through a MUX, which is controlled | |
| 27 | through GPIO pins. | |
| 28 | ||
| 29 | This driver can also be built as a module. If so, the module | |
| e7065e20 | 30 | will be called i2c-mux-gpio. |

34 | help |
| 35 | If you say yes here you get support for the NXP PCA9541 | |
| 36 | I2C Master Selector. | |
| 37 | ||
| 38 | This driver can also be built as a module. If so, the module | |
| b4f0b74e | 39 | will be called i2c-mux-pca9541. |

| 45 | If you say yes here you get support for the Philips PCA954x | |
| 46 | I2C mux/switch devices. | |

| 52 | tristate "pinctrl-based I2C multiplexer" | |
| 53 | depends on PINCTRL | |
| 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. | |
| 59 | ||
| 60 | This driver can also be built as a module. If so, the module will be | |
| 61 | called pinctrl-i2cmux. | |
