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 help 23 If you say yes here you get support for the NXP PCA9541 24 I2C Master Selector. 25 26 This driver can also be built as a module. If so, the module 27 will be called i2c-mux-pca9541. 28 29config I2C_MUX_PCA954x 30 tristate "Philips PCA954x I2C Mux/switches" 31 help 32 If you say yes here you get support for the Philips PCA954x 33 I2C mux/switch devices. 34 35 This driver can also be built as a module. If so, the module 36 will be called i2c-mux-pca954x. 37 38config I2C_MUX_PINCTRL 39 tristate "pinctrl-based I2C multiplexer" 40 depends on PINCTRL 41 help 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. 46 47 This driver can also be built as a module. If so, the module will be 48 called pinctrl-i2cmux. 49 50endmenu 51
