+title: Socionext SynQuacer External Interrupt Unit (EXIU)
+
+maintainers:
+  - Ard Biesheuvel <ardb@kernel.org>
+
+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
+
+  socionext,spi-base:
+    $ref: /schemas/types.yaml#/definitions/uint32
+    description: The SPI number of the first SPI of the 32 adjacent ones the
+      EXIU forwards its interrupts to.
