      6 * struct lis3lv02d_platform_data - lis3 chip family platform data
      7 * @click_flags:	Click detection unit configuration
      8 * @click_thresh_x:	Click detection unit x axis threshold
      9 * @click_thresh_y:	Click detection unit y axis threshold
     10 * @click_thresh_z:	Click detection unit z axis threshold
     11 * @click_time_limit:	Click detection unit time parameter
     12 * @click_latency:	Click detection unit latency parameter
     13 * @click_window:	Click detection unit window parameter
     14 * @irq_cfg:		On chip irq source and type configuration (click /
     15 *			data available / wake up, open drain, polarity)
     16 * @irq_flags1:		Additional irq triggering flags for irq channel 0
     17 * @irq_flags2:		Additional irq triggering flags for irq channel 1
     18 * @duration1:		Wake up unit 1 duration parameter
     19 * @duration2:		Wake up unit 2 duration parameter
     20 * @wakeup_flags:	Wake up unit 1 flags
     21 * @wakeup_thresh:	Wake up unit 1 threshold value
     22 * @wakeup_flags2:	Wake up unit 2 flags
     23 * @wakeup_thresh2:	Wake up unit 2 threshold value
     24 * @hipass_ctrl:	High pass filter control (enable / disable, cut off
     25 *			frequency)
     26 * @axis_x:		Sensor orientation remapping for x-axis
     27 * @axis_y:		Sensor orientation remapping for y-axis
     28 * @axis_z:		Sensor orientation remapping for z-axis
     29 * @driver_features:	Enable bits for different features. Disabled by default
     30 * @default_rate:	Default sampling rate. 0 means reset default
     31 * @setup_resources:	Interrupt line setup call back function
     32 * @release_resources:	Interrupt line release call back function
     33 * @st_min_limits[3]:	Selftest acceptance minimum values
     34 * @st_max_limits[3]:	Selftest acceptance maximum values
     35 * @irq2:		Irq line 2 number
     36 *
     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.
