1 Kernel driver gpio-i2cmux
6 -----------
8 gpio-i2cmux is an i2c mux driver providing access to I2C bus segments
9 from a master I2C bus and a hardware MUX controlled through GPIO pins.

29 gpio-i2cmux uses the platform bus, so you need to provide a struct
32 bus, the number of bus segments to create and the GPIO pins used
33 to control it. See include/linux/gpio-i2cmux.h for details.
35 E.G. something like this for a MUX providing 4 bus segments
36 controlled through 3 GPIO pins:
38 #include <linux/gpio-i2cmux.h>
