Hello,
I would like to know how we configure interrupts in falling edge or rising
edge with RTDM.
I have to rewrite a linux driver in RTDM module and I don't find the
equivalent of IRQF_TRIGGER_FALLING.
Best Regards
Perrine

There is no such thing in RTDM. You can use set_irq_type() for this,
like some Linux drivers do as well. But the cleaner approach indeed seem
to be to let RTDM manage the flags (and check if there conflicts in case
of shared IRQs). Will put it on the todo list, but not with a high prio.

I can use set_irq_type() just before rtdm_irq_request() ?
I don't use shared IRQs, so I wouldn't have any problem.
