Subject: [PATCH v1 2/2] of: irq: Ignore disabled interrupt controllers
Date: Wed, 27 Nov 2013 23:26:13 -0800	[thread overview]
Message-ID: <e395866d7910723ed8cf82ba9475ef51ac6443f2.1385623064.git.peter.crosthwaite@xilinx.com> (raw)
In-Reply-To: <cover.1385623064.git.peter.crosthwaite@xilinx.com>
In-Reply-To: <cover.1385623064.git.peter.crosthwaite@xilinx.com>

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.
