| help | |
| This enables I2C buses to be multiplexed, so that you can select | |
| one of several buses using some sort of control mechanism. The | |
| bus select is handled automatically when that bus is accessed, | |
| using a suitable I2C MUX driver. | |

| help | |
| If you say yes to this option, support will be included for an | |
| I2C multimaster arbitration scheme using GPIOs and a challenge & | |
