Subject: [PATCH 182/203] of/irq: Pass trigger type in IRQ resource flags
|
|
|
|
Some drivers might rely on availability of trigger flags in IRQ
|
|
resource, for example to configure the hardware for particular interrupt
|
|
type. However current code creating IRQ resources from data in device
|
|
tree does not configure trigger flags in resulting resources.
|
|
|
|
This patch tries to solve the problem, based on the fact that
|
|
irq_of_parse_and_map() configures the trigger based on DT interrupt
|
|
specifier and IRQD_TRIGGER_* flags are consistent with IORESOURCE_IRQ_*,
|
|
and we can get correct trigger flags by calling irqd_get_trigger_type()
|
|
after mapping the interrupt.
