1LIS302 accelerometer devicetree bindings2 3This device is matched via its bus drivers, and has a number of properties4that 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 index10 - spi-max-frequency: maximal bus speed, should be set to 1000000 unless11 constrained by external circuitry12 - interrupts: the interrupt generated by the device13 14Required properties for the I2C bindings:15 - compatible: should be set to "st,lis3lv02d"16 - reg: i2c slave address17 - Vdd-supply: The input supply for Vdd18 - Vdd_IO-supply: The input supply for Vdd_IO19 20 21Optional properties for all bus drivers:22 23 - st,click-single-{x,y,z}: if present, tells the device to issue an24 interrupt on single click events on the25 x/y/z axis.26 - st,click-double-{x,y,z}: if present, tells the device to issue an27 interrupt on double click events on the28 x/y/z axis.29 - st,click-thresh-{x,y,z}: set the x/y/z axis threshold30 - st,click-click-time-limit: click time limit, from 0 to 127.5msec31 with step of 0.5 msec32 - st,click-latency: click latency, from 0 to 255 msec with33 step of 1 msec.34 - st,click-window: click window, from 0 to 255 msec with35 step of 1 msec.36 - st,irq{1,2}-disable: disable IRQ 1/237 - st,irq{1,2}-ff-wu-1: raise IRQ 1/2 on FF_WU_1 condition38 - st,irq{1,2}-ff-wu-2: raise IRQ 1/2 on FF_WU_2 condition39 - st,irq{1,2}-data-ready: raise IRQ 1/2 on data ready condition40 - st,irq{1,2}-click: raise IRQ 1/2 on click condition41 - st,irq-open-drain: consider IRQ lines open-drain42 - st,irq-active-low: make IRQ lines active low43 - st,wu-duration-1: duration register for Free-Fall/Wake-Up44 interrupt 145 - st,wu-duration-2: duration register for Free-Fall/Wake-Up46 interrupt 247 - st,wakeup-{x,y,z}-{lo,hi}: set wakeup condition on x/y/z axis for48 upper/lower limit49 - st,wakeup-threshold: set wakeup threshold50 - st,wakeup2-{x,y,z}-{lo,hi}: set wakeup condition on x/y/z axis for51 upper/lower limit for second wakeup52 engine.53 - st,wakeup2-threshold: set wakeup threshold for second wakeup54 engine.55 - st,highpass-cutoff-hz=: 1, 2, 4 or 8 for 1Hz, 2Hz, 4Hz or 8Hz of56 highpass cut-off frequency57 - st,hipass{1,2}-disable: disable highpass 1/2.58 - st,default-rate=: set the default rate59 - 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 axis62 (used by self-test)63 64 65Example for a SPI device node:66 67 accelerometer@0 {68 compatible = "st,lis302dl-spi";69 reg = <0>;70 spi-max-frequency = <1000000>;71 interrupt-parent = <&gpio>;72 interrupts = <104 0>;73 74 st,click-single-x;75 st,click-single-y;76 st,click-single-z;77 st,click-thresh-x = <10>;78 st,click-thresh-y = <10>;79 st,click-thresh-z = <10>;80 st,irq1-click;81 st,irq2-click;82 st,wakeup-x-lo;83 st,wakeup-x-hi;84 st,wakeup-y-lo;85 st,wakeup-y-hi;86 st,wakeup-z-lo;87 st,wakeup-z-hi;88 };89 90Example for a I2C device node:91 92 lis331dlh: accelerometer@18 {93 compatible = "st,lis331dlh", "st,lis3lv02d";94 reg = <0x18>;95 Vdd-supply = <&lis3_reg>;96 Vdd_IO-supply = <&lis3_reg>;97 98 st,click-single-x;99 st,click-single-y;100 st,click-single-z;101 st,click-thresh-x = <10>;102 st,click-thresh-y = <10>;103 st,click-thresh-z = <10>;104 st,irq1-click;105 st,irq2-click;106 st,wakeup-x-lo;107 st,wakeup-x-hi;108 st,wakeup-y-lo;109 st,wakeup-y-hi;110 st,wakeup-z-lo;111 st,wakeup-z-hi;112 st,min-limit-x = <120>;113 st,min-limit-y = <120>;114 st,min-limit-z = <140>;115 st,max-limit-x = <550>;116 st,max-limit-y = <550>;117 st,max-limit-z = <750>;118 };119 120
