This interrupt controller is found in the Actions Semi Owl SoCs (S500, S700 and S900) and provides support for handling up to 3 external interrupt lines. Each line can be independently configured as interrupt and triggers on either of the edges or either of the levels. Additionally, each line can also be masked individually.
