+ * 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.
