General informations

The Linux kernel configuration item CONFIG_MUX_GPIO:

• prompt: GPIO-controlled Multiplexer
• type: tristate
• depends on: CONFIG_GPIOLIB || CONFIG_COMPILE_TEST
• defined in drivers/mux/Kconfig

• modules built: mux-gpio

Help text

GPIO-controlled Multiplexer controller.

The driver builds a single multiplexer controller using a number of gpio pins. For N pins, there will be 2^N possible multiplexer states. The GPIO pins can be connected (by the hardware) to several multiplexers, which in that case will be operated in parallel.

To compile the driver as a module, choose M here: the module will be called mux-gpio.
