1 LIS302 accelerometer devicetree bindings
2
3 This device is matched via its bus drivers, and has a number of properties
4 that apply in on the generic device (independent from the bus).
5
6
7 Required 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
14 Required 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
21 Optional 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)
