The MULTIPLEXER question in the Kconfig might be confusing and is of dubious value. Remove it. This makes consumers responsible for selecting MULTIPLEXER, which they already do.

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.
