+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";

+The driver supports interrupt-driven and interrupt-less operation, depending

+the optional generation of IIO events on rising/falling light threshold changes
+requires the use of interrupts. Without interrupts, only the simple reading
+of the current light value is supported through the IIO API.

+* UPISEMI us5182d I2C ALS and Proximity sensor
+
+Required properties:
+- compatible: must be "upisemi,usd5182"
+- reg: the I2C address of the device
+
+Optional properties:
+- upisemi,glass-coef: glass attenuation factor - compensation factor of
+ resolution 1000 for material transmittance.
+
+- upisemi,dark-ths: array of 8 elements containing 16-bit thresholds (adc
+ counts) corresponding to every scale.
+
+- upisemi,upper-dark-gain: 8-bit dark gain compensation factor(4 int and 4
+ fractional bits - Q4.4) applied when light > threshold
+
+- upisemi,lower-dark-gain: 8-bit dark gain compensation factor(4 int and 4
+ fractional bits - Q4.4) applied when light < threshold
+
+- upisemi,continuous: This chip has two power modes: one-shot (chip takes one
+ measurement and then shuts itself down) and continuous (
+ chip takes continuous measurements). The one-shot mode is
+ more power-friendly but the continuous mode may be more
+ reliable. If this property is specified the continuous
+ mode will be used instead of the default one-shot one for
+ raw reads.
+
+If the optional properties are not specified these factors will default to the
+values in the below example.
+The glass-coef defaults to no compensation for the covering material.
+The threshold array defaults to experimental values that work with US5182D
+sensor on evaluation board - roughly between 12-32 lux.
+There will be no dark-gain compensation by default when ALS > thresh
+(0 * dark-gain), and a 1.35 compensation factor when ALS < thresh.
