description: |
  AMS/TAOS TSL2591 is a very-high sensitivity
  light-to-digital converter that transforms light intensity into a digital
  signal.

properties:
  compatible:
    const: amstaos,tsl2591

  reg:
    maxItems: 1

  interrupts:
    maxItems: 1
    description:
      Interrupt (INT:Pin 2) Active low. Should be set to IRQ_TYPE_EDGE_FALLING.
      interrupt is used to detect if the light intensity has fallen below
      or reached above the configured threshold values.

required:
  - compatible
  - reg

additionalProperties: false
