- config I2C_MUX
- bool "Suport I2C multiplexers"
- depends on DM_I2C
- 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.
- config I2C_ARB_GPIO_CHALLENGE
- bool "GPIO-based I2C arbitration"
- depends on I2C_MUX
- help
- If you say yes to this option, support will be included for an
- I2C multimaster arbitration scheme using GPIOs and a challenge &
- response mechanism where masters have to claim the bus by asserting
- a GPIO.
