0001 LIS302 accelerometer devicetree bindings
0002
0003 This device is matched via its bus drivers, and has a number of properties
0004 that apply in on the generic device (independent from the bus).
0005
0006
0007 Required properties for the SPI bindings:
0008 - compatible: should be set to "st,lis3lv02d-spi"
0009 - reg: the chipselect index
0010 - spi-max-frequency: maximal bus speed, should be set to 1000000 unless
0011 constrained by external circuitry
0012 - interrupts: the interrupt generated by the device
0013
0014 Required properties for the I2C bindings:
0015 - compatible: should be set to "st,lis3lv02d"
0016 - reg: i2c slave address
0017 - Vdd-supply: The input supply for Vdd
0018 - Vdd_IO-supply: The input supply for Vdd_IO
0019
0020
0021 Optional properties for all bus drivers:
0022
0023 - st,click-single-{x,y,z}: if present, tells the device to issue an
0024 interrupt on single click events on the
0025 x/y/z axis.
0026 - st,click-double-{x,y,z}: if present, tells the device to issue an
0027 interrupt on double click events on the
0028 x/y/z axis.
0029 - st,click-thresh-{x,y,z}: set the x/y/z axis threshold
0030 - st,click-click-time-limit: click time limit, from 0 to 127.5msec
0031 with step of 0.5 msec
0032 - st,click-latency: click latency, from 0 to 255 msec with
0033 step of 1 msec.
0034 - st,click-window: click window, from 0 to 255 msec with
0035 step of 1 msec.
0036 - st,irq{1,2}-disable: disable IRQ 1/2
0037 - st,irq{1,2}-ff-wu-1: raise IRQ 1/2 on FF_WU_1 condition
0038 - st,irq{1,2}-ff-wu-2: raise IRQ 1/2 on FF_WU_2 condition
0039 - st,irq{1,2}-data-ready: raise IRQ 1/2 on data ready contition
0040 - st,irq{1,2}-click: raise IRQ 1/2 on click condition
0041 - st,irq-open-drain: consider IRQ lines open-drain
0042 - st,irq-active-low: make IRQ lines active low
0043 - st,wu-duration-1: duration register for Free-Fall/Wake-Up
0044 interrupt 1
0045 - st,wu-duration-2: duration register for Free-Fall/Wake-Up
0046 interrupt 2
0047 - st,wakeup-{x,y,z}-{lo,hi}: set wakeup condition on x/y/z axis for
0048 upper/lower limit
0049 - st,wakeup-threshold: set wakeup threshold
0050 - st,wakeup2-{x,y,z}-{lo,hi}: set wakeup condition on x/y/z axis for
0051 upper/lower limit for second wakeup
0052 engine.
0053 - st,wakeup2-threshold: set wakeup threshold for second wakeup
0054 engine.
0055 - st,highpass-cutoff-hz=: 1, 2, 4 or 8 for 1Hz, 2Hz, 4Hz or 8Hz of
0056 highpass cut-off frequency
0057 - st,hipass{1,2}-disable: disable highpass 1/2.
0058 - st,default-rate=: set the default rate
0059 - st,axis-{x,y,z}=: set the axis to map to the three coordinates.
0060 Negative values can be used for inverted axis.
0061 - st,{min,max}-limit-{x,y,z} set the min/max limits for x/y/z axis
0062 (used by self-test)
