+ * Platform data is used to setup the sensor chip. Meaning of the different
+ * chip features can be found from the data sheet. Currently the 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 impossible to explain meaning of the
+ * fields here. Behaviour of the detection blocks varies heavily depending
+ * on the configuration. 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.
