description: |
  This interrupt controller is found in the Actions Semi Owl SoCs (S500, S700
  and S900) and provides support for handling up to 3 external interrupt lines.

properties:
  compatible:
    enum:
      - actions,s500-sirq
      - actions,s700-sirq
      - actions,s900-sirq

  reg:
    maxItems: 1

  interrupt-controller: true

  '#interrupt-cells':
    const: 2
    description:
      The first cell is the input IRQ number, between 0 and 2, while the second
      cell is the trigger type as defined in interrupt.txt in this directory.

  interrupts:
    description: |
      Contains the GIC SPI IRQs mapped to the external interrupt lines.
      They shall be specified sequentially from output 0 to 2.
    minItems: 3
    maxItems: 3

required:
  - compatible
  - reg
  - interrupt-controller
