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. | |

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. |

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. | |
