| 10 | depends on GENERIC_GPIO |
| 11 | help |
| 12 | If you say yes to this option, support will be included for a |
| 13 | GPIO based I2C multiplexer. This driver provides access to |
| 14 | I2C busses connected through a MUX, which is controlled |
| 15 | through GPIO pins. |
| 16 | |
| 17 | This driver can also be built as a module. If so, the module |
| Jean Delvare | e7065e2 | 2012-04-28 15:32:06 +0200 | [diff] [blame] | 18 | will be called i2c-mux-gpio. |

| 42 | depends on PINCTRL |
| 43 | help |
| 44 | If you say yes to this option, support will be included for an I2C |
| 45 | multiplexer that uses the pinctrl subsystem, i.e. pin multiplexing. |
| 46 | This is useful for SoCs whose I2C module's signals can be routed to |
| 47 | different sets of pins at run-time. |
| 48 | |
| 49 | This driver can also be built as a module. If so, the module will be |
| 50 | called pinctrl-i2cmux. |
