I am looking at 3rd type, and evaulating that for embedded systems
devices having haptics chips can be programmed under drivers/input or
not. It is kind of early discussion and gathering inputs on what could
be lacking part in input subsystem for support such category of
devices.

Is it possible for you to submit your version of code and drivers? It
will be good starting point for discussion.
