| 13 | If you say yes to this option, support will be included for an |
| 14 | I2C multimaster arbitration scheme using GPIOs and a challenge & |
| 15 | response mechanism where masters have to claim the bus by asserting |
| 16 | a GPIO. |
| 17 | |
| 18 | This driver can also be built as a module. If so, the module |
| 19 | will be called i2c-arb-gpio-challenge. |
