+title: Intel IXP4xx XScale Networking Processors Interrupt Controller

+
+description: |
+  This interrupt controller is found in the Intel IXP4xx processors.
+  Some processors have 32 interrupts, some have up to 64 interrupts.
+  The exact number of interrupts is determined from the compatible
+  string.
+
+  The distinct IXP4xx families with different interrupt controller
+  variations are IXP42x, IXP43x, IXP45x and IXP46x. Those four
+  families were the only ones to reach the developer and consumer
+  market.
+
+properties:
+  compatible:
+    items:
+      - enum:
+        - intel,ixp42x-interrupt
+        - intel,ixp43x-interrupt
+        - intel,ixp45x-interrupt
+        - intel,ixp46x-interrupt
