The Cirrus Logic CS48L31/32/33 audio codecs contain a programmable interrupt controller with a variety of interrupt sources, including GPIOs that can be used as interrupt inputs.

This driver provides the handling for the interrupt controller. As the codec is accessed via regmap, the generic regmap_irq functionality is used to do most of the work.

I cannot spot a shred of interrupt controller code in there. This belongs IMO to the MFD code. It is also a direct copy of the existing irq-madera.c code, duplicated for no obvious reason.
