+description: |
+  Bindings for the ambient light sensor veml6030 from Vishay
+  Semiconductors over an i2c interface.
+
+  Irrespective of whether interrupt is used or not, application
+  can get the ALS and White channel reading from IIO raw interface.
+
+  If the interrupts are used, application will receive an IIO event
+  whenever configured threshold is crossed.
+
+  Specifications about the sensor can be found at:
+    https://www.vishay.com/docs/84366/veml6030.pdf
+
+properties:
+  compatible:
+    enum:
+      - vishay,veml6030
+
+  reg:
+    description:
+      I2C address of the device.
+    enum:
+      - 0x10 # ADDR pin pulled down
+      - 0x48 # ADDR pin pulled up
+
+  interrupts:
+    description:
+      interrupt mapping for IRQ. Configure with IRQ_TYPE_LEVEL_LOW.
+      Refer to interrupt-controller/interrupts.txt for generic
+      interrupt client node bindings.
+    maxItems: 1
+
+required:
+  - compatible

+examples:

+        #size-cells = <0>;
