The edge detection must - be set to IRQ_TYPE_EDGE_BOTH so as to detect movements toward - and away from the proximity sensor. -- io-channels: the ADC channel used for converting the voltage from - AOUT to a digital representation. -- io-channel-names: must be "aout" - -Optional properties: -- vdd-supply: regulator supplying VDD power to the component. -- capella,aset-resistance-ohms: the sensitivity calibration resistance, - in Ohms. Valid values are: 50000, 100000, 300000 and 600000, - as these are the resistance values that we are supplied with - calibration curves for.
