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.

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

|
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.
