  1LIS302 accelerometer devicetree bindings
  2
  3This device is matched via its bus drivers, and has a number of properties
  4that apply in on the generic device (independent from the bus).
  5
  6
  7Required properties for the SPI bindings:
  8 - compatible: 		should be set to "st,lis3lv02d-spi"
  9 - reg:			the chipselect index
 10 - spi-max-frequency:	maximal bus speed, should be set to 1000000 unless
 11			constrained by external circuitry
 12 - interrupts:		the interrupt generated by the device
 13
 14Required properties for the I2C bindings:
 15 - compatible:		should be set to "st,lis3lv02d"
 16 - reg:			i2c slave address
 17 - Vdd-supply:		The input supply for Vdd
 18 - Vdd_IO-supply:	The input supply for Vdd_IO
 19
 20
 21Optional properties for all bus drivers:
 22
 23 - st,click-single-{x,y,z}:	if present, tells the device to issue an
 24				interrupt on single click events on the
 25				x/y/z axis.
 26 - st,click-double-{x,y,z}:	if present, tells the device to issue an
 27				interrupt on double click events on the
 28				x/y/z axis.
 29 - st,click-thresh-{x,y,z}:	set the x/y/z axis threshold
 30 - st,click-click-time-limit:	click time limit, from 0 to 127.5msec
 31				with step of 0.5 msec
 32 - st,click-latency:		click latency, from 0 to 255 msec with
 33				step of 1 msec.
 34 - st,click-window:		click window, from 0 to 255 msec with
 35				step of 1 msec.
 36 - st,irq{1,2}-disable:		disable IRQ 1/2
 37 - st,irq{1,2}-ff-wu-1:		raise IRQ 1/2 on FF_WU_1 condition
 38 - st,irq{1,2}-ff-wu-2:		raise IRQ 1/2 on FF_WU_2 condition
 39 - st,irq{1,2}-data-ready:	raise IRQ 1/2 on data ready condition
 40 - st,irq{1,2}-click:		raise IRQ 1/2 on click condition
 41 - st,irq-open-drain:		consider IRQ lines open-drain
 42 - st,irq-active-low:		make IRQ lines active low
 43 - st,wu-duration-1:		duration register for Free-Fall/Wake-Up
 44				interrupt 1
 45 - st,wu-duration-2:		duration register for Free-Fall/Wake-Up
 46				interrupt 2
 47 - st,wakeup-{x,y,z}-{lo,hi}:	set wakeup condition on x/y/z axis for
 48				upper/lower limit
 49 - st,wakeup-threshold:		set wakeup threshold
 50 - st,wakeup2-{x,y,z}-{lo,hi}:	set wakeup condition on x/y/z axis for
 51				upper/lower limit for second wakeup
 52				engine.
 53 - st,wakeup2-threshold:	set wakeup threshold for second wakeup
 54				engine.
 55 - st,highpass-cutoff-hz=:	1, 2, 4 or 8 for 1Hz, 2Hz, 4Hz or 8Hz of
 56				highpass cut-off frequency
 57 - st,hipass{1,2}-disable:	disable highpass 1/2.
 58 - st,default-rate=:		set the default rate
 59 - st,axis-{x,y,z}=:		set the axis to map to the three coordinates.
 60				Negative values can be used for inverted axis.
 61 - st,{min,max}-limit-{x,y,z}	set the min/max limits for x/y/z axis
 62				(used by self-test)
