	  ADG792A and ADG792G Wide Bandwidth Triple 4:1 Multiplexers

	  The driver supports both operating the three multiplexers in
	  parallel and operating them independently.

	  To compile the driver as a module, choose M here: the module will
	  be called mux-adg792a.

	  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.

	  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.
