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
