13
  Bindings for the ambient light sensors veml6030 and veml6035 from

14
  Vishay Semiconductors over an i2c interface.

15


16
  Irrespective of whether interrupt is used or not, application

17
  can get the ALS and White channel reading from IIO raw interface.

18


19
  If the interrupts are used, application will receive an IIO event

20
  whenever configured threshold is crossed.
