Setup a range of interrupts with a generic chip
void irq_setup_generic_chip(struct irq_chip_generic * gc, u32 msk, enum irq_gc_flags flags, unsigned int clr, unsigned int set);
gc
Generic irq chip holding all data
msk
Bitmask holding the irqs to initialize relative to gc->irq_base
flags
Flags for initialization
clr
IRQ_* bits to clear
set
IRQ_* bits to set
Set up max. 32 interrupts starting from gc->irq_base. Note, this initializes all interrupts to the primary irq_chip_type and its associated handler.
