From bf49be02d6f92b95c2462e5027fc90b98f62e324 Mon Sep 17 00:00:00 2001 From: Peter Crosthwaite Date: Wed, 27 Nov 2013 23:26:13 -0800 Subject: [PATCH] of: irq: Ignore disabled interrupt controllers When searching the system for interrupt controllers, skip over any that are explicitly disabled. This makes interrupt controllers consistent with regular devices, which can be marked as do-not-probe via the status = "disabled" dts property.
