/**

 * struct lis3lv02d_platform_data - lis3 chip family platform data

 * @click_flags:	Click detection unit configuration

 * @click_thresh_x:	Click detection unit x axis threshold

 * @click_thresh_y:	Click detection unit y axis threshold

 * @click_thresh_z:	Click detection unit z axis threshold

 * @click_time_limit:	Click detection unit time parameter

 * @click_latency:	Click detection unit latency parameter

 * @click_window:	Click detection unit window parameter

 * @irq_cfg:		On chip irq source and type configuration (click /

 *			data available / wake up, open drain, polarity)

 * @irq_flags1:		Additional irq triggering flags for irq channel 0

 * @irq_flags2:		Additional irq triggering flags for irq channel 1

 * @duration1:		Wake up unit 1 duration parameter

 * @duration2:		Wake up unit 2 duration parameter

 * @wakeup_flags:	Wake up unit 1 flags

 * @wakeup_thresh:	Wake up unit 1 threshold value

 * @wakeup_flags2:	Wake up unit 2 flags

 * @wakeup_thresh2:	Wake up unit 2 threshold value

 * @hipass_ctrl:	High pass filter control (enable / disable, cut off

 *			frequency)

 * @axis_x:		Sensor orientation remapping for x-axis

 * @axis_y:		Sensor orientation remapping for y-axis

 * @axis_z:		Sensor orientation remapping for z-axis

 * @driver_features:	Enable bits for different features. Disabled by default

 * @default_rate:	Default sampling rate. 0 means reset default

 * @setup_resources:	Interrupt line setup call back function

 * @release_resources:	Interrupt line release call back function

 * @st_min_limits[3]:	Selftest acceptance minimum values

 * @st_max_limits[3]:	Selftest acceptance maximum values

 * @irq2:		Irq line 2 number

 *

 * 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.
