  1. config I2C_MUX
  2. bool "Suport I2C multiplexers"
  3. depends on DM_I2C
  4. help
  5. This enables I2C buses to be multiplexed, so that you can select
  6. one of several buses using some sort of control mechanism. The
  7. bus select is handled automatically when that bus is accessed,
  8. using a suitable I2C MUX driver.
  9. config I2C_ARB_GPIO_CHALLENGE
  10. bool "GPIO-based I2C arbitration"
  11. depends on I2C_MUX
  12. help
  13. If you say yes to this option, support will be included for an
  14. I2C multimaster arbitration scheme using GPIOs and a challenge &
