I'm glad you got it to work with two drivers for the same device.
With this binding, I'm still a bit unhappy about the st,lpc-mode property,
in particular since you rely on a shared include file for something that
can only be set in one way or another and always has to be present.
Why not just use a boolean property that enforces one mode when present
and another mode when absent?
