1 LIS302 accelerometer devicetree bindings
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).
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
15 Optional properties for all bus drivers:
17 - st,click-single-{x,y,z}: if present, tells the device to issue an
18 interrupt on single click events on the
20 - st,click-double-{x,y,z}: if present, tells the device to issue an
21 interrupt on double click events on the
23 - st,click-thresh-{x,y,z}: set the x/y/z axis threshold
24 - st,click-click-time-limit: click time limit, from 0 to 127.5msec
26 - st,click-latency: click latency, from 0 to 255 msec with
28 - st,click-window: click window, from 0 to 255 msec with
30 - st,irq{1,2}-disable: disable IRQ 1/2
31 - st,irq{1,2}-ff-wu-1: raise IRQ 1/2 on FF_WU_1 condition
32 - st,irq{1,2}-ff-wu-2: raise IRQ 1/2 on FF_WU_2 condition
33 - st,irq{1,2}-data-ready: raise IRQ 1/2 on data ready contition
34 - st,irq{1,2}-click: raise IRQ 1/2 on click condition
35 - st,irq-open-drain: consider IRQ lines open-drain
36 - st,irq-active-low: make IRQ lines active low
37 - st,wu-duration-1: duration register for Free-Fall/Wake-Up
39 - st,wu-duration-2: duration register for Free-Fall/Wake-Up
41 - st,wakeup-{x,y,z}-{lo,hi}: set wakeup condition on x/y/z axis for
43 - st,highpass-cutoff-hz=: 1, 2, 4 or 8 for 1Hz, 2Hz, 4Hz or 8Hz of
44 highpass cut-off frequency
45 - st,hipass{1,2}-disable: disable highpass 1/2.
46 - st,default-rate=: set the default rate
47 - st,axis-{x,y,z}=: set the axis to map to the three coordinates
48 - st,{min,max}-limit-{x,y,z} set the min/max limits for x/y/z axis
52 Example for a SPI device node:
55 compatible = "st,lis302dl-spi";
57 spi-max-frequency = <1000000>;
58 interrupt-parent = <&gpio>;
64 st,click-thresh-x = <10>;
65 st,click-thresh-y = <10>;
66 st,click-thresh-z = <10>;
