Could you give me a bit more hints or point where to start? I've tried
to build sandbox, but it fails for v2021.01 release (I've did make
sandbox_defconfig && make all). I assume I would need to add adc and
adc-keys devices to some sandbox dts and some code triggering and
checking the key values, but that's all I know now.
Well you do need to be able to build sandbox or you will get
nowhere...what error did you get? Once we understand what went wrong
we can update the docs. Maybe it is missing a dependency.

This is pretty mysterious. Are you sure you are using an x86_64 machine?
r9 relates to ARMv7.
You have to unset CROSS_COMPILE when you build the sandbox.
The sandbox runs fine on aarch64.
There are a bunch of errors currently when building on 32bit
architectures. Simon has a lot of patches pending.
Best regards
