2 # Multiplexer I2C chip drivers configuration
5 menu "Multiplexer I2C Chip support"
9 tristate "GPIO-based I2C multiplexer"
10 depends on GENERIC_GPIO
12 If you say yes to this option, support will be included for a
13 GPIO based I2C multiplexer. This driver provides access to
14 I2C busses connected through a MUX, which is controlled
17 This driver can also be built as a module. If so, the module
18 will be called i2c-mux-gpio.
20 config I2C_MUX_PCA9541
21 tristate "NXP PCA9541 I2C Master Selector"
22 depends on EXPERIMENTAL
24 If you say yes here you get support for the NXP PCA9541
27 This driver can also be built as a module. If so, the module
28 will be called i2c-mux-pca9541.
30 config I2C_MUX_PCA954x
31 tristate "Philips PCA954x I2C Mux/switches"
32 depends on EXPERIMENTAL
34 If you say yes here you get support for the Philips PCA954x
35 I2C mux/switch devices.
37 This driver can also be built as a module. If so, the module
38 will be called i2c-mux-pca954x.
40 config I2C_MUX_PINCTRL
41 tristate "pinctrl-based I2C multiplexer"
44 If you say yes to this option, support will be included for an I2C
45 multiplexer that uses the pinctrl subsystem, i.e. pin multiplexing.
46 This is useful for SoCs whose I2C module's signals can be routed to
47 different sets of pins at run-time.
49 This driver can also be built as a module. If so, the module will be
50 called pinctrl-i2cmux.
