-* AMS/TAOS ALS and proximity sensor
-
-Required properties:
-
-  - compatible: Should be one of
-		"amstaos,tsl2571"
-		"amstaos,tsl2671"
-		"amstaos,tmd2671"
-		"amstaos,tsl2771"
-		"amstaos,tmd2771"
-		"amstaos,tsl2572"
-		"amstaos,tsl2672"
-		"amstaos,tmd2672"
-		"amstaos,tsl2772"
-		"amstaos,tmd2772"
-		"avago,apds9930"
-  - reg: the I2C address of the device
-
-Optional properties:
-
-  - amstaos,proximity-diodes - proximity diodes to enable. <0>, <1>, or <0 1>
-                               are the only valid values.
-  - led-max-microamp - current for the proximity LED. Must be 100000, 50000,
-                       25000, or 13000.
-  - vdd-supply: phandle to the regulator that provides power to the sensor.
-  - vddio-supply: phandle to the regulator that provides power to the bus.
-  - interrupts: the sole interrupt generated by the device
-
-  Refer to interrupt-controller/interrupts.txt for generic interrupt client
-  node bindings.
-
-Example:
-
-tsl2772@39 {
-	compatible = "amstaos,tsl2772";
-	reg = <0x39>;
-	interrupts-extended = <&msmgpio 61 IRQ_TYPE_EDGE_FALLING>;
-	vdd-supply = <&pm8941_l17>;
-	vddio-supply = <&pm8941_lvs1>;
-	amstaos,proximity-diodes = <0>;
-	led-max-microamp = <100000>;
-};
