From: Sid Manning <[email protected]> l2vic_set_irq() clears a level-triggered source's pending bit on de-assertion, so a source that drops before it is latched into int_status is not spuriously re-delivered on the next ciad. Edge-triggered sources (int_type set) keep the pulse semantics they already have via SOFT_INT/set_irq(level=1).
