+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 at 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>;
+	};
