From 000e99c3334cdddaec020d7324fe4ca2a683d3dd Mon Sep 17 00:00:00 2001 From: Lennert Buytenhek Date: Sun, 18 May 2008 19:46:59 +0200 Subject: [ARM] Orion: top-level IRQs are level-triggered Make it clear that Orion top-level IRQs are level-triggered. This means that we don't need an ->ack() handler, or at least, we don't need the ->ack() handler (or the acking part of the ->mask_ack() handler) to actually do anything. Given that, we might as well point our ->mask_ack() handler at the ->mask() handler instead of providing a dummy ->ack() handler, since providing a ->mask_ack() handler on level IRQ sources will prevent ->ack() from ever being called.
