+description: |
+  The Kalray Core Interrupt Controller is tightly integrated in each kv3 core
+  present in the Coolidge SoC.
+
+  It provides the following features:
+  - 32 independent interrupt sources
+  - 2-bit configurable priority level
+  - 2-bit configurable ownership level
+
+properties:
+  compatible:
+    const: kalray,kv3-1-intc

+  "#interrupt-cells":
+    const: 1
+    description:
+      The IRQ number.

+  interrupt-controller: true
+
+additionalProperties: false

+required:
+  - compatible
+  - "#interrupt-cells"
+  - "#address-cells"
