    I'm not sure if we want these "historical" files. We don't have them for
    the other input types, and I believe that it's not the driver's job to
    compute and export these values. If anyone cares about the history of
    sensed values, that's something for a user-space application to
    implement. This will also be much more flexible in user-space, as it
    becomes possible to decide the exact time range to consider, to
    remember at which time the peak occurred, etc.
