   13   AMS/TAOS TSL2591 is a very-high sensitivity
   14   light-to-digital converter that transforms light intensity into a digital
   15   signal.
   16 
   17 properties:
   18   compatible:
   19     const: amstaos,tsl2591
   20 
   21   reg:
   22     maxItems: 1
   23 
   24   interrupts:
   25     maxItems: 1
   26     description:
   27       Interrupt (INT:Pin 2) Active low. Should be set to IRQ_TYPE_EDGE_FALLING.
   28       interrupt is used to detect if the light intensity has fallen below
   29       or reached above the configured threshold values.
