description: |+
  The Socionext SynQuacer SoC has an external interrupt unit (EXIU)
  that forwards a block of 32 configurable input lines to 32 adjacent
  level-high type GICv3 SPIs.

properties:
  compatible:
    const: socionext,synquacer-exiu

  reg:
    maxItems: 1

  '#interrupt-cells':
    const: 3

  interrupt-controller: true
