To compile the driver as a module, choose M here: the module will be called mux-adg792a. config MUX_GPIO tristate "GPIO-controlled Multiplexer" depends on GPIOLIB || COMPILE_TEST help 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. config MUX_MMIO tristate "MMIO register bitfield-controlled Multiplexer" depends on (OF && MFD_SYSCON) || COMPILE_TEST help MMIO register bitfield-controlled Multiplexer controller. The driver builds multiplexer controllers for bitfields in a syscon register. For N bit wide bitfields, there will be 2^N possible multiplexer states. To compile the driver as a module, choose M here: the module will be called mux-mmio. endmenu
