implement vibrator on/off control driver The piece implemented here is just the HW on/off driver; on top of this driver there will be a VIBR service (to be implemented in RiViera land) that will implement vibration pulse trains.

/*
 * This header file is a FreeCalypso addition: it defines the functional
 * interface to the hardware vibrator driver.
