SYNOPSIS
enum irq_gc_flags {
IRQ_GC_INIT_MASK_CACHE,
IRQ_GC_INIT_NESTED_LOCK,
IRQ_GC_MASK_CACHE_PER_TYPE,
IRQ_GC_NO_MASK
};
CONSTANTS
IRQ_GC_INIT_MASK_CACHE
- Initialize the mask_cache by reading mask reg
IRQ_GC_INIT_NESTED_LOCK
- Set the lock class of the irqs to nested for irq chips which need to call irq_set_wake on the parent irq. Usually GPIO implementations
IRQ_GC_MASK_CACHE_PER_TYPE
- Mask cache is chip type private
IRQ_GC_NO_MASK
- Do not calculate irq_data->mask
