+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
