*
* 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.
