On a side note, this is a totally configuration-free peripheral that doesn't do
anything crazy until manually configured.

In the slow quest to be (hopefully) more sane about the defaults, should we keep
them enabled by default? Bjorn?

But many (most?) devices don't have a vibration motor connected to
PMI632, some (like devboards) don't have anything, and other phones have
a separate chip that controls the vibration motor.

Enabling this by default would mean all devices with PMI632 would get an
input device for the vibrator that probably doesn't work?

Regards
Luca
