From b797318666dade9675a253d311125ae7b568e2f8 Mon Sep 17 00:00:00 2001 From: Alexander Graf Date: Wed, 24 Sep 2014 12:32:17 +0200 Subject: sysbus: Expose IRQ enumeration helpers Sysbus devices can get their IRQ lines connected to other devices. It is possible to figure out which IRQ line a connection is on and whether a sysbus device even provides an IRQ connector at a specific offset. This patch exposes helpers to make this information publicly accessible. We will need it for the platform bus dynamic sysbus enumeration.
