-VISHAY VCNL4035 -  Ambient Light and proximity sensor
-
-Link to datasheet: https://www.vishay.com/docs/84251/vcnl4035x01.pdf
-
-Required properties:
-
-	-compatible: should be "vishay,vcnl4035"
-	-reg: I2C address of the sensor, should be 0x60
-	-interrupts: interrupt mapping for GPIO IRQ (level active low)
-
-Example:
-
-light-sensor@60 {
-	compatible = "vishay,vcnl4035";
-	reg = <0x60>;
-	interrupt-parent = <&gpio4>;
-	interrupts = <11 IRQ_TYPE_LEVEL_LOW>;
-};
