0013 description: |
0014 This interrupt controller is found in the Intel IXP4xx processors.
0015 Some processors have 32 interrupts, some have up to 64 interrupts.
0016 The exact number of interrupts is determined from the compatible
0017 string.
0018
0019 The distinct IXP4xx families with different interrupt controller
0020 variations are IXP42x, IXP43x, IXP45x and IXP46x. Those four
0021 families were the only ones to reach the developer and consumer
0022 market.
