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.
