+title: Integrated Proximity Sensor With Infrared Emitter
+
+maintainers:
+  - Ivan Mikhaylov <i.mikhaylov@...ro.com>
+
+description: |
+  The VCNL3020 is a fully integrated proximity sensor. Fully integrated means
+  that the infrared emitter is included in the package. It has 16-bit
+  resolution. It includes a signal processing IC and features standard I2C
+  communication interface. It features an interrupt function.
+
+  Specifications about the devices can be found at:
+  https://www.vishay.com/docs/84150/vcnl3020.pdf
+
+properties:
+  compatible:
+    enum:
+      - vishay,vcnl3020
+
+  reg:
+    maxItems: 1
+
+  led-current:
+    description:
+        IR LED current value with valid Range = 0 to 20d. e.g. 0 = 0 mA,
+        1 = 10 mA, 20 = 200 mA (2 = 20 mA = DEFAULT). LED Current is
+        limited to 200 mA for values higher than decimal 20.
+
+required:
+  - compatible
+  - reg
+  - led-current
