| * 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. |
