11 - Linus Walleij <linus.walleij@linaro.org>
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
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
