1config I2C_MUX
2	bool "Support 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.

14	  This enables I2C buses to be multiplexed, so that you can select
15	  one of several buses using some sort of control mechanism. The

20	bool "GPIO-based I2C arbitration"
21	depends on I2C_MUX
22	help
23	  If you say yes to this option, support will be included for an
24	  I2C multimaster arbitration scheme using GPIOs and a challenge &
25	  response mechanism where masters have to claim the bus by asserting
26	  a GPIO.

30	depends on I2C_MUX
31	help
32	  If you say yes here you get support for the TI PCA954x I2C mux/switch
33	  devices. It is x width I2C multiplexer which enables to partitioning
34	  I2C bus and connect multiple devices with the same address to the same
35	  I2C controller where driver handles proper routing to target i2c
36	  device. Supported chips are PCA9543, PCA9544, PCA9546, PCA9547,
37	  PCA9548 and PCA9646.

41	depends on I2C_MUX && DM_GPIO
42	help
43	  If you say yes to this option, support will be included for
44	  a GPIO based I2C multiplexer. This driver provides access to
45	  I2C busses connected through a MUX, which is controlled
46	  through GPIO pins.
