The large number (>150) of internal interrupt\nsources are managed by an on-board interrupt controller.\n\nThis driver provides the handling for the interrupt controller. As the\ncodec is accessed via regmap, we can make use of the generic IRQ\nfunctionality from regmap to do most of the work. Only around half of\nthe possible interrupt source are currently of interest from the driver\nso only this subset is defined. Others can be added in future if needed.\n\nThe KConfig options are not user-configurable because this driver is\nmandatory so is automatically included when the parent MFD driver is\nselected.\n\nSigned-off-by: Richard Fitzgerald <rf@opensource.wolfsonmicro.com>\nSigned-off-by: Charles Keepax <ckeepax@opensource.wolfsonmicro.com>\n---\nChanges since V4:\n- Fixed missing
