The Sigma Designs SMP86xx and SMP87xx chips use a secondary interrupt controller with 64 inputs. The inputs go to an edge/level detector, the outputs of which are replicated to three mask blocks, each with a separate primary IRQ.
These patches add a device tree binding and an irqchip driver for this controller.
