2018-12-18irqchip: Add driver for Cirrus Logic Madera codecsRichard Fitzgerald1-0/+256
The Cirrus Logic Madera codecs (Cirrus Logic CS47L35/85/90/91 and WM1840) are highly complex devices containing up to 7 programmable DSPs and many other internal sources of interrupts plus a number of GPIOs that can be used as interrupt inputs. The large number (>150) of internal interrupt sources are managed by an on-board interrupt controller. This driver provides the handling for the interrupt controller. As the codec is accessed via regmap, we can make use of the generic IRQ functionality from regmap to do most of the work. Only around half of the possible interrupt source are currently of interest from the driver so only this subset is defined. Others can be added in future if needed. The KConfig options are not user-configurable because this driver is mandatory so is automatically included when the parent MFD driver is selected.
