+
+maintainers:
+ - Ivan Mikhaylov <i.mikhaylov@yadro.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

+ iio-proximity@13 {
+ compatible = "vishay,vcnl3020";
+ reg = <0x13>;
+
+ led-current = <0x14>;
