Hi,
Legacy interrupts are level triggered, but i see some RC drivers use
flow handler "handle_simple_irq" instead why they are not using
"handle_level_irq" ?
Why they are registering dummy_irq_chip with "handle_simple_irq", if
they use this chip how the irq type is set for this virtual irq (level
or edge).
Regards,
vamiki
