Message-Id: <ee3c0c716da8f1b1146d8829bc5184fbf1c3ead2.1385623064.git.peter.crosthwaite@xilinx.com> Date: Wed, 27 Nov 2013 23:26:12 -0800 From: Peter Crosthwaite <peter.crosthwaite@...inx.com> To: grant-likely@...aro.org, devicetree@...r.kernel.org, linux-kernel@...r.kernel.org Cc: rob.herring@...xeda.com Subject: [PATCH v1 1/2] of: irq: Ignore disabled intc's when searching map When searching the interrupt map, if a matched parent is disabled, just ignore it and move on with the search. This allows for specifying connection of a single device IRQ to multiple interrupt controllers via the interrupt map schema. This change allows for selection of the active interrupt controller via the already existing status = "disabled" mechanism.
