+LIS302 accelerometer devicetree bindings
+
+This device is matched via its bus drivers, and has a number of properties
+that apply in on the generic device (independent from the bus).
+
+
+Required properties for the SPI bindings:
+ - compatible: should be set to "st,lis3lv02d_spi"
+ - reg: the chipselect index
+ - spi-max-frequency: maximal bus speed, should be set to 1000000 unless
+ constrained by external circuitry
+ - interrupts: the interrupt generated by the device
+
+Required properties for the I2C bindings:
+ - compatible: should be set to "st,lis3lv02d"
+ - reg: i2c slave address
+ - Vdd-supply: The input supply for Vdd
+ - Vdd_IO-supply: The input supply for Vdd_IO
+
+
+Optional properties for all bus drivers:
+
+ - st,click-single-{x,y,z}: if present, tells the device to issue an
+ interrupt on single click events on the
+ x/y/z axis.
+ - st,click-double-{x,y,z}: if present, tells the device to issue an
+ interrupt on double click events on the
+ x/y/z axis.
+ - st,click-thresh-{x,y,z}: set the x/y/z axis threshold
+ - st,click-click-time-limit: click time limit, from 0 to 127.5msec
+ with step of 0.5 msec
+ - st,click-latency: click latency, from 0 to 255 msec with
+ step of 1 msec.
+ - st,click-window: click window, from 0 to 255 msec with
+ step of 1 msec.
+ - st,irq{1,2}-disable: disable IRQ 1/2
+ - st,irq{1,2}-ff-wu-1: raise IRQ 1/2 on FF_WU_1 condition
+ - st,irq{1,2}-ff-wu-2: raise IRQ 1/2 on FF_WU_2 condition
+ - st,irq{1,2}-data-ready: raise IRQ 1/2 on data ready contition
+ - st,irq{1,2}-click: raise IRQ 1/2 on click condition
+ - st,irq-open-drain: consider IRQ lines open-drain
+ - st,irq-active-low: make IRQ lines active low
+ - st,wu-duration-1: duration register for Free-Fall/Wake-Up
+ interrupt 1
+ - st,wu-duration-2: duration register for Free-Fall/Wake-Up
+ interrupt 2
+ - st,wakeup-{x,y,z}-{lo,hi}: set wakeup condition on x/y/z axis for
+ upper/lower limit
+ - st,wakeup-threshold: set wakeup threshold
+ - st,wakeup2-{x,y,z}-{lo,hi}: set wakeup condition on x/y/z axis for
+ upper/lower limit for second wakeup
+ engine.
+ - st,wakeup2-threshold: set wakeup threshold for second wakeup
+ engine.
+ - st,highpass-cutoff-hz=: 1, 2, 4 or 8 for 1Hz, 2Hz, 4Hz or 8Hz of
+ highpass cut-off frequency
+ - st,hipass{1,2}-disable: disable highpass 1/2.
+ - st,default-rate=: set the default rate
+ - st,axis-{x,y,z}=: set the axis to map to the three coordinates.
+ Negative values can be used for inverted axis.
+ - st,{min,max}-limit-{x,y,z} set the min/max limits for x/y/z axis
+ (used by self-test)
+
+
+Example for a SPI device node:
+
+ lis302@0 {
+ compatible = "st,lis302dl-spi";
+ reg = <0>;
+ spi-max-frequency = <1000000>;

+Required properties:

+- reg: the I2C address of the device
+
+Optional properties:
+- upisemi,glass-coef: glass attenuation factor - compensation factor of

+- upisemi,dark-ths: array of 8 elements containing 16-bit thresholds (adc
+ counts) corresponding to every scale.
+- upisemi,upper-dark-gain: 8-bit dark gain compensation factor(4 int and 4
+ fractional bits - Q4.4) applied when light > threshold
+- upisemi,lower-dark-gain: 8-bit dark gain compensation factor(4 int and 4

+
+If the optional properties are not specified these factors will default to the

+The glass-coef defaults to no compensation for the covering material.
+The threshold array defaults to experimental values that work with US5182D

+There will be no dark-gain compensation by default when ALS > thresh
+(0 * dark-gain), and a 1.35 compensation factor when ALS < thresh.
