I'm trying to enable the dm9000 driver for DT support. I've run into
a problem with the interrupt flags. The dm9000 driver is expecting to
get them passed in on the resource flags:
unsigned long irqflags = db->irq_res->flags & IRQF_TRIGGER_MASK;
But of_irq_to_resource() is not adding them:
r->flags = IORESOURCE_IRQ;
Now if I trace into of_irq_to_resource() it calls
irq_of_parse_and_map() which calls irq_create_of_mapping() which then
calls domain->ops->dt_translate() to get the flags. So we have the
flags down the callstack but passing them back means adding a
parameter to a public API.
I can't see any API to ask an irq for its current flags. That would be
another way to get them and add them to the resource.
Any other options?
