13description: |
14  This interrupt controller is found in the Intel IXP4xx processors.
15  Some processors have 32 interrupts, some have up to 64 interrupts.
16  The exact number of interrupts is determined from the compatible
17  string.
18
19  The distinct IXP4xx families with different interrupt controller
20  variations are IXP42x, IXP43x, IXP45x and IXP46x. Those four
21  families were the only ones to reach the developer and consumer
22  market.
