Since commit 0166dc11be ("of: make CONFIG_OF user selectable"), it
is possible to test-build any driver which depends on OF on any
architecture by explicitly selecting OF. Therefore depending on
COMPILE_TEST as an alternative is no longer needed.
It is actually better to always build such drivers with OF enabled,
so that the test builds are closer to how each driver will actually be
built on its intended target. Building them without OF may not test
much as the compiler will optimize out potentially large parts of the
code. In the worst case, this could even pop false positive warnings.
Dropping COMPILE_TEST here improves the quality of our testing and
avoids wasting time on non-existent issues.
As a minor optimization, this also lets us drop of_match_ptr(), as we
now know what it will resolve to, we might as well save cpp some work.

Multiplexer devices
config MULTIPLEXER tristate
menu "Multiplexer drivers" depends on MULTIPLEXER
config MUX_ADG792A tristate "Analog Devices ADG792A/ADG792G Multiplexers" depends on I2C help 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.
config MUX_ADGS1408 tristate "Analog Devices ADGS1408/ADGS1409 Multiplexers" depends on SPI help ADGS1408 8:1 multiplexer and ADGS1409 double 4:1 multiplexer switches.
To compile the driver as a module, choose M here: the module will
be called mux-adgs1408.
config MUX_GPIO tristate "GPIO-controlled Multiplexer" depends on GPIOLIB || COMPILE_TEST help 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.
config MUX_MMIO tristate "MMIO/Regmap register bitfield-controlled Multiplexer" depends on OF help 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.
