LIS302 accelerometer devicetree bindings This device is matched via its bus drivers, and has a number of properties that apply in on the generic device (independent from the bus). Required properties for the SPI bindings: - compatible: should be set to "st,lis3lv02d-spi" - reg: the chipselect index - spi-max-frequency: maximal bus speed, should be set to 1000000 unless constrained by external circuitry - interrupts: the interrupt generated by the device Required properties for the I2C bindings: - compatible: should be set to "st,lis3lv02d" - reg: i2c slave address - Vdd-supply: The input supply for Vdd - Vdd_IO-supply: The input supply for Vdd_IO Optional properties for all bus drivers: - st,click-single-{x,y,z}: if present, tells the device to issue an interrupt on single click events on the x/y/z axis. - st,click-double-{x,y,z}: if present, tells the device to issue an interrupt on double click events on the x/y/z axis. - st,click-thresh-{x,y,z}: set the x/y/z axis threshold - st,click-click-time-limit: click time limit, from 0 to 127.5msec with step of 0.5 msec - st,click-latency: click latency, from 0 to 255 msec with step of 1 msec. - st,click-window: click window, from 0 to 255 msec with step of 1 msec. - st,irq{1,2}-disable: disable IRQ 1/2 - st,irq{1,2}-ff-wu-1: raise IRQ 1/2 on FF_WU_1 condition - st,irq{1,2}-ff-wu-2: raise IRQ 1/2 on FF_WU_2 condition - st,irq{1,2}-data-ready: raise IRQ 1/2 on data ready contition - st,irq{1,2}-click: raise IRQ 1/2 on click condition - st,irq-open-drain: consider IRQ lines open-drain - st,irq-active-low: make IRQ lines active low - st,wu-duration-1: duration register for Free-Fall/Wake-Up interrupt 1 - st,wu-duration-2: duration register for Free-Fall/Wake-Up interrupt 2 - st,wakeup-{x,y,z}-{lo,hi}: set wakeup condition on x/y/z axis for upper/lower limit - st,wakeup-threshold: set wakeup threshold - st,wakeup2-{x,y,z}-{lo,hi}: set wakeup condition on x/y/z axis for upper/lower limit for second wakeup engine. - st,wakeup2-threshold: set wakeup threshold for second wakeup engine. - st,highpass-cutoff-hz=: 1, 2, 4 or 8 for 1Hz, 2Hz, 4Hz or 8Hz of highpass cut-off frequency - st,hipass{1,2}-disable: disable highpass 1/2. - st,default-rate=: set the default rate - st,axis-{x,y,z}=: set the axis to map to the three coordinates. Negative values can be used for inverted axis. - st,{min,max}-limit-{x,y,z} set the min/max limits for x/y/z axis (used by self-test) Example for a SPI device node: accelerometer@0 { compatible = "st,lis302dl-spi"; reg = <0>; spi-max-frequency = <1000000>; interrupt-parent = <&gpio>; interrupts = <104 0>; st,click-single-x; st,click-single-y; st,click-single-z; st,click-thresh-x = <10>; st,click-thresh-y = <10>; st,click-thresh-z = <10>; st,irq1-click; st,irq2-click; st,wakeup-x-lo; st,wakeup-x-hi; st,wakeup-y-lo; st,wakeup-y-hi; st,wakeup-z-lo; st,wakeup-z-hi; }; Example for a I2C device node: lis331dlh: accelerometer@18 { compatible = "st,lis331dlh", "st,lis3lv02d"; reg = <0x18>; Vdd-supply = <&lis3_reg>; Vdd_IO-supply = <&lis3_reg>; st,click-single-x; st,click-single-y; st,click-single-z; st,click-thresh-x = <10>; st,click-thresh-y = <10>; st,click-thresh-z = <10>; st,irq1-click; st,irq2-click; st,wakeup-x-lo; st,wakeup-x-hi; st,wakeup-y-lo; st,wakeup-y-hi; st,wakeup-z-lo; st,wakeup-z-hi; st,min-limit-x = <120>; st,min-limit-y = <120>; st,min-limit-z = <140>; st,max-limit-x = <550>; st,max-limit-y = <550>; st,max-limit-z = <750>; };
