This driver provides access to 14 I2C busses connected through a MUX, which is controlled 15 through GPIO pins. 16 17 This driver can also be built as a module. If so, the module 18 will be called i2c-mux-gpio. 19 20config I2C_MUX_PCA9541 21 tristate "NXP PCA9541 I2C Master Selector" 22 depends on EXPERIMENTAL 23 help 24 If you say yes here you get support for the NXP PCA9541 25 I2C Master Selector. 26 27 This driver can also be built as a module. If so, the module 28 will be called i2c-mux-pca9541. 29 30config I2C_MUX_PCA954x 31 tristate "Philips PCA954x I2C Mux/switches" 32 depends on EXPERIMENTAL 33 help 34 If you say yes here you get support for the Philips PCA954x 35 I2C mux/switch devices. 36 37 This driver can also be built as a module. If so, the module 38 will be called i2c-mux-pca954x. 39 40config I2C_MUX_PINCTRL 41 tristate "pinctrl-based I2C multiplexer" 42 depends on PINCTRL 43 help 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. 48 49 This driver can also be built as a module. If so, the module will be 50 called pinctrl-i2cmux. 51 52endmenu 53
