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