+title: Intel IXP4xx XScale Networking Processors Interrupt Controller
+
+maintainers:
+ - Linus Walleij <linus.walleij@linaro.org>
+
+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.
