Avago apds993x and apds990x ambient light + proximity combo driver.
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
|
||
|
|
- compatible : Should be "avago,apds9930" or "avago,apds9900".
|
||
|
|
- reg : i2c slave address of the device.
|
||
|
|
- pinctrl-names : The pinctrl configration names of this sensor driver. Should be
|
||
|
|
"default" and "sleep".
|
||
|
|
- pinctrl-0 : Should specify pin control groups used for this controller.
|
||
|
|
- pinctrl-1 : Should specify pin control groups used for this controller.
|
||
|
|
- interrupt-parent : Parent of interrupt.
|
||
|
|
- interupts : L/P sample interrupt to indicate new data ready.
|
||
|
|
- vdd-supply : Power supply needed to power up the device.
|
||
|
|
- vio-supply : IO power supply needed for IO and I2C.
|
||
|
|
- avago,irq-gpio : The gpio pin for the interrupt.
|
||
|
|
- avago,ps-threshold : The threshold adc value for proximity sensor
|
||
|
|
to trigger away interrupt.
|
||
|
|
- avago,ps-hysteresis-threshold: The hysteresis threshold adc value for
|
||
|
|
proximity sensor to trigger close interrupt.
|
||
|
|
- avago,ps-pulse : The proximity pulse that the LDR will generate.
|
||
|
|
- avago,ps-gain : The proximity gain of the sensor.
|
||
|
|
- avago,als-B : Tuning value of COE_B parameter.
|
||
|
|
- avago,als-C : Tuning value of COE_C parameter.
|
||
|
|
- avago,als-D : Tuning value of COE_D parameter.
|
||
|
|
- avago,ga-value : Tuning value of the gain for light sensor.
|
||
|
|
|
||
|
|
Optional properties:
|
||
|
|
|
||
|
|
- avago,cross-talk : Calibrate the threshold of proximity sensor.
|
||
|
|
the cross-talk value is raw data of proximity.
|
||
|
|
|
||
|
|
- avago,default-cal : Boolean to select calibration,if this property is defined
|
||
|
|
sensor will be use default calibration, otherwise the sensor
|
||
|
|
will be use factroy calibration.
|
