This driver is registered as an input device with sysfs control
interface, but it still can output 3 axes data in non-interrupt mode.

This is primarily an input device but can also be used as for other things.
It thus exposes the power control (so you can keep power on when you want) and
x/y/z co-ordinates directly.

I'd be more happy if it was just an input device. If non-wired interrupt
is a common case then we should probably add polled input device mode,
but we certainly should not register completely non-functional input
device as the driver does now.

We also have a way of retrieving current (or rather most recent)
coordinates via EVIOCGABS so I am not sure why we want the sysfs way of
retrieving coordinates as well.

Regarding power mode - I really believe that this should be done on the
driver core level instead of implementing "manual off" in every single
driver out there.

definitely.  Know anyone with the time / inclination to get that added?
