- config I2C_MUX
- bool "Support 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 SPL_I2C_MUX
- bool "Support I2C multiplexers on SPL"
- depends on I2C_MUX
- 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.
- config I2C_MUX_PCA954x
- tristate "TI PCA954x I2C Mux/switches"
- depends on I2C_MUX
- help
- If you say yes here you get support for the TI PCA954x
- I2C mux/switch devices. It is x width I2C multiplexer which enables to
- paritioning I2C bus and connect multiple devices with the same address
- to the same I2C controller where driver handles proper routing to
- target i2c device. PCA9544 and PCA9548 are supported.
