enum_irq_gc_flags: Initialization flags for generic irq chips

NAME

enum_irq_gc_flags - Initialization flags for generic irq chips

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,
  IRQ_GC_BE_IO
};  

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

IRQ_GC_BE_IO

Use big-endian register accesses (default: LE)
