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/Regmap register bitfield-controlled Multiplexer controller.
The driver builds multiplexer controllers for bitfields in either
a syscon register or a driver regmap 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.
