2 # Multiplexer I2C chip drivers configuration
5 menu "Multiplexer I2C Chip support"
9 tristate "GPIO-based I2C multiplexer"
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"
23 If you say yes here you get support for the NXP PCA9541
26 This driver can also be built as a module. If so, the module
27 will be called i2c-mux-pca9541.
29 config I2C_MUX_PCA954x
30 tristate "Philips PCA954x I2C Mux/switches"
32 If you say yes here you get support for the Philips PCA954x
33 I2C mux/switch devices.
35 This driver can also be built as a module. If so, the module
36 will be called i2c-mux-pca954x.
38 config I2C_MUX_PINCTRL
39 tristate "pinctrl-based I2C multiplexer"
42 If you say yes to this option, support will be included for an I2C
43 multiplexer that uses the pinctrl subsystem, i.e. pin multiplexing.
44 This is useful for SoCs whose I2C module's signals can be routed to
45 different sets of pins at run-time.
47 This driver can also be built as a module. If so, the module will be
48 called pinctrl-i2cmux.
