COMPILE_TEST makes no sense when I2C is disabled, as the driver cannot compile
in that configuration:
drivers/mux/mux-adg792a.c: In function 'adg792a_write_cmd':
drivers/mux/mux-adg792a.c:34:9: error: implicit declaration of function 'i2c_smbus_write_byte_data'; did you mean 'i2c_set_clientdata'? [-Werror=implicit-function-declaration]

mux-adg792a.c:(.init.text+0x14): undefined reference to `i2c_register_driver'

Multiplexer controller subsystem. Multiplexers are used in a
|
|
variety of settings, and this subsystem abstracts their use
|
|
so that the rest of the kernel sees a common interface. When
|
|
multiple parallel multiplexers are controlled by one single
|
|
multiplexer controller, this subsystem also coordinates the
|
|
multiplexer accesses.
|
|
|
|
To compile the subsystem as a module, choose M here: the module will
|
|
be called mux-core.

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.
