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,highpass-cutoff-hz=: 1, 2, 4 or 8 for 1Hz, 2Hz, 4Hz or 8Hz of 50 highpass cut-off frequency 51 - st,hipass{1,2}-disable: disable highpass 1/2. 52 - st,default-rate=: set the default rate 53 - st,axis-{x,y,z}=: set the axis to map to the three coordinates 54 - st,{min,max}-limit-{x,y,z} set the min/max limits for x/y/z axis 55 (used by self-test) 56 57 58Example for a SPI device node: 59 60 lis302@0 { 61 compatible = "st,lis302dl-spi"; 62 reg = <0>; 63 spi-max-frequency = <1000000>; 64 interrupt-parent = <&gpio>; 65 interrupts = <104 0>; 66 67 st,click-single-x; 68 st,click-single-y; 69 st,click-single-z; 70 st,click-thresh-x = <10>; 71 st,click-thresh-y = <10>; 72 st,click-thresh-z = <10>; 73 st,irq1-click; 74 st,irq2-click; 75 st,wakeup-x-lo; 76 st,wakeup-x-hi; 77 st,wakeup-y-lo; 78 st,wakeup-y-hi; 79 st,wakeup-z-lo; 80 st,wakeup-z-hi; 81 }; 82 83Example for a I2C device node: 84 85 lis331dlh: lis331dlh@18 { 86 compatible = "st,lis331dlh", "st,lis3lv02d"; 87 reg = <0x18>; 88 Vdd-supply = <&lis3_reg>; 89 Vdd_IO-supply = <&lis3_reg>; 90 91 st,click-single-x; 92 st,click-single-y; 93 st,click-single-z; 94 st,click-thresh-x = <10>; 95 st,click-thresh-y = <10>; 96 st,click-thresh-z = <10>; 97 st,irq1-click; 98 st,irq2-click; 99 st,wakeup-x-lo; 100 st,wakeup-x-hi; 101 st,wakeup-y-lo; 102 st,wakeup-y-hi; 103 st,wakeup-z-lo; 104 st,wakeup-z-hi; 105 st,min-limit-x = <120>; 106 st,min-limit-y = <120>; 107 st,min-limit-z = <140>; 108 st,max-limit-x = <550>; 109 st,max-limit-y = <550>; 110 st,max-limit-z = <750>; 111 }; 112 113
