   * Platform data is used to setup the sensor chip. Meaning of the different
   * chip features can be found from the data sheet. It is publicly available
   * at www.st.com web pages. Currently the platform data is used
   * only for the 8 bit device. The 8 bit device has two wake up / free fall
   * detection units and click detection unit. There are plenty of ways to
   * configure the chip which makes is quite hard to explain deeper meaning of
   * the fields here. Behaviour of the detection blocks varies heavily depending
   * on the configuration. For example, interrupt detection block can use high
   * pass filtered data which makes it react to the changes in the acceleration.
   * Irq_flags can be used to enable interrupt detection on the both edges.
   * With proper chip configuration this produces interrupt when some trigger
   * starts and when it goes away.
