-Capella Microsystems CM3605
-Ambient Light and Short Distance Proximity Sensor
-
-The CM3605 is an entirely analog part which however require quite a bit of
-software logic to interface a host operating system.
-
-This ALS and proximity sensor was one of the very first deployed in mobile
-handsets, notably it is used in the very first Nexus One Android phone from
-2010.
-
-Required properties:
-- compatible: must be: "capella,cm3605"
-- aset-gpios: GPIO line controlling the ASET line (drive low
- to activate the ALS, should be flagged GPIO_ACTIVE_LOW)
-- interrupts: the IRQ line (such as a GPIO) that is connected to
- the POUT (proximity sensor out) line. 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. If not supplied, 100 kOhm will be assumed
- but it is strongly recommended to supply this.
-
-Example:
-
-cm3605 {
- compatible = "capella,cm3605";
- vdd-supply = <&foo_reg>;
- aset-gpios = <&foo_gpio 1 GPIO_ACTIVE_LOW>;
- capella,aset-resistance-ohms = <100000>;
- interrupts = <1 IRQ_TYPE_EDGE_BOTH>;
- io-channels = <&adc 0x01>;
- io-channel-names = "aout";
-};
