Summary
Now, IRQ multiplexing contains no more secrets for you. In this chapter, we discussed the most important elements of IRQ management in Linux systems, the IRQ domain API. You learned the basics for developing interrupt controller drivers and managing their bindings from within the DT. IRQ propagation was discussed so that you could understand what happens from the request to the handling. This chapter will help you to understand the interrupt-driven part of the next chapter, which deals with input device drivers.
