From a67202583f44c90d1155f4de8c8028884a2a1451 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Sat, 15 Jun 2013 23:56:32 +0200 Subject: [PATCH] ARM: integrator: get the LM interrupts from DT The OF/DT boot path needs to get the LM (Logical Module) IRQs from the device tree for coherency. This augments the DT syscon node to contain these IRQs and alter the DT LM code to get them from there.
