+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>;
