+Avago APDS990X driver
+
+Required properties:
+- compatible: "avago,apds990x"
+- reg: address on the I2C bus
+- interrupts: external interrupt line number
+- Vdd-supply: power supply for VDD
+- Vled-supply: power supply for LEDA
+- ga: Glass attenuation
+- cf1: Clear channel factor 1
+- irf1: IR channel factor 1
+- cf2: Clear channel factor 2
+- irf2: IR channel factor 2
+- df: Device factor
+- pdrive: IR current, one of APDS_IRLED_CURR_XXXmA values
+- ppcount: Proximity pulse count
+
+Example (Nokia N9):
+
+ als_ps@39 {
+ compatible = "avago,apds990x";
+ reg = <0x39>;
+
+ interrupt-parent = <&gpio3>;
+ interrupts = <19 10>; /* gpio_83, IRQF_TRIGGER_FALLING | IRQF_TRIGGER_LOW */
+
+ Vdd-supply = <&vaux1>;
+ Vled-supply = <&vbat>;
+
+ ga = <168834>;
+ cf1 = <4096>;
+ irf1 = <7824>;
+ cf2 = <877>;
+ irf2 = <1575>;
+ df = <52>;
+
+ pdrive = <0x2>; /* APDS_IRLED_CURR_25mA */
+ ppcount = <5>;
+ };
