1LIS302 accelerometer devicetree bindings 2 3This device is matched via its bus drivers, and has a number of properties 4that 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 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 14Required 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 21Optional 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 contition 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) 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
